(8 GGO) The Israeli attack on the U.S.S. Liberty some 14 years ago was, indeed, a
wrenching experience for U.S. Sigint agencies. The loss, particularly in the case of those Sigint
specialists who gave their lives or were wounded, was difficult to accept. The knowledge that the
tragedy resulted not only from Israeli miscalculation but also from faulty U. S. communications
practices was even more difficult to accept.
(8 060) The passage of time has made it possible for the authors to reexamine the Liberty
incident objectively and answer a number of persistent questions. The authors accordingly set
forth the technical rationale for the Liberty mission, the particulars of the Israeli miscalculation,
the details of the American communications failures, a narrative of the attack and of attempts
to minimize the compromise of cryptologic materials, and the lessons to be learned from the
(6 660) Finally, this is also an account of the way the U.S. Sigint agencies organized
their response to requirements brought on by a crisis situation. As such, it has much to offer the
student of U.S. cryptologic operations.
(G 000) A word about the authors, who worked on this project part time after they had
retired. An experienced operations officer and research specialist, Mr. Gerhard headed the NSA-
SCA Task Force that produced the Southeast Asia History Series, as well as the Special Research
Element that produced studies of Sigint crisis situations. Mr. Millington, who spent most of his
career in research and documentation activities, was for years in charge of the NSA Library.

Chapter I
Political-Military Background (U)
(V) A brief look at the Middle Eastern
situation during early 1967 is necessary for an appre-
ciation of the mounting political and military tensions
that ultimately led to the U.S. decision to position
the V.S.S. Liberty in the eastern Mediterranean.
(U) Since the mid-1950s, the major world
powers had been keenly aware of and sensitive to the
buildup of tensions in the Middle East. Both the
Soviet Union and Communist China were quick to take
advantage of unsettled conditions there to extend their
own influence over governments wherever possible -
often competing with one another in this effort.
(U) By the end of the 19508 the Chinese
Communists had begun to assert themselves, especially
in Iraq and Syria. In May 1966, Syria's new president,
Nureddin el-Attassi, scoffed at waging a conventional
war against Israel and urged what he called a "people's
war of liberation," Chinese-Communist style.
head of the Palestine Liberation Organization (PLO),
Ahmed Shukairy, also admitted to receiving Chinese
aid. PLO representatives had been sent to Vietnam
and communist China to observe communist guerrilla
techniques, and PLO troops were receiving arms from
Communist China.
(U) As for the Soviets, they had particular
cause for not wishing to see the Syrian Government
humiliated, defeated, and, perhaps, overthrown. The
increasingly radical Syrian Governments which had
assumed power since the beginning of 1966 had come
to rely more and more on Soviet military and economic
aid, to permit increasing numbers of Soviet advisers
to be stationed in the country, and all in all to offer
the most promising field for Soviet penetration and
influence in the Middle East. The Soviets genuinely
feared massive Israeli retaliation that might topple
the Syrian Government; they therefore spurred the
Egyptians on to vigorous counteraction, the full reper-
cussions of which they could not foresee."
(U) The United States supported the
United Nations' efforts to maintain peace in the area
and, while championing the right of the State of Israel
to exist, urged restraint and respect for the rights of
all nations.
(U) Within the Arab world, President
Gamal Abdel Nasser of the United Arab Republic
(U.A.R.) sought to overcome opposition to his leader-
ship by the monarchies of Saudi Arabia and Jordan."
In late January 1967, when U.A.R. aircraft bombed
Najran in Saudi Arabia, relations between the two
countries were further strained. In Yemen, the U.A.R.
supported the insurgents against the Royalists. Jordan,
trying to keep from becoming embroiled in Israeli-
Arab frictions, ordered in March a halt to Arab
infiltration into Israel through Jordanian territory as
well as a cessation of Palestine Liberation internal
agitation against the Jordanian Government.
(V) Between January and April 1967, the
Syrian-Israeli frontier was the scene of a series of
escalating clashes ranging from potshots at tractors to
exchanges of fire between tanks, artillery, and aircraft.
Both sides refused, at different times, to permit the
United Nations Mixed Armistice Commission to mark
the armistice line at disputed points and insisted on
farming and patrolling disputed areas. S
(8 GGO) On 7 April 1967, a Syrian-Israeli clash
escalated from an exchange of fire between tanks to
attacks by both Syrian and Israeli aircraft. By the
end of the day, Israeli planes had appeared over the
outskirts of Damascus and six Syrian planes had been
shot down. This event triggered a Sigint Readiness
"Alfa" called by NSA for Middle East targets. The
Alfa was terminated three days later."
(B-CCO) As the tempo of the civil war within
Yemen increased, V.A.R. aircraft dropped poison-gas
bombs on Yemeni Royalists on 22 April. Later that
month when the Yemeni Government imprisoned two
Americans from the Agency for International Devel-

(U) The U.S.S. Liberty was commissioned in May 1945 as a victory ship and later converted into a technical research ship (December
1964). She had an overall length of 455 feet. a maximum speed of 18 knots with an allowable personnel complement of 9 officers and
151 enlisted men along with an additional 6 officers and 128 enlisted men from the Naval Security Group.

( ~ - e e ~ ) From 11-14 May, UA.R. aircraft at-
Itacked towns in Saudi Arabial I
(8-888) When on 14 May the D.A.R. placed
its air defense units on full alert and deployed its
tactical naval units, NSA expanded its Alfa to embrace
all Middle East targets.
(U) On 17 May, the D.A.R. requested
that the United Nations Emergency Force (DNEF)
withdraw from the Gaza Strip. The UN. complied,
and Nasser immediately began moving troops into the
Sinai. This decision by the D.A.R. government -
presumably encouraged by the Soviets and Syrians
- to move its armed forces up to the Sinai armistice
line thus reestablished the direct Egyptian-Israeli
military confrontation which had been the major
immediate cause of the 1956 war. 10
(8 GGO) Five days later on 23 May 1967, the
D.A.R. blockaded the Strait of Tiran, thereby closing
the Gulf of Aqaba to Israeli shipping and prohibiting
unescorted tankers of any flag from reaching the
Israeli port of Elat. This action reproduced another
element that had brought on the 1956 war. Because
Israel had repeatedly asserted that she would go to
war if the UA.R. blocked the Gulf, NSA raised its
Alfa to a Sigint Readiness "Bravo Crayon" for all
Middle East communications. II
(D) The D.A.R. blockade precipitated
quiet but full-scale mobilization by Israel. Arab forces
were repositioned, and on 30 May Egypt and Jordan
signed a five-year military alliance, completing Arab
encirclement of Israel. Shortly thereafter, Soviet naval
vessels entered the Mediterranean through the
Dardenelles. 12
(D) On 1 June, as pressure to open the
Strait of Tiran built within Israel, Moshe Dayan was
appointed Israeli Minister of Defense. The next day,
Friday, 2 June, the United States and the United
Kingdom issued a joint statement declaring the Gulf
of Aqaba an international waterway to which all states
were entitled free passage.
(D) The weekend of 3 and 4 June passed
uneventfully, but then lightning struck. On Monday,
5 June at approximately 0845 Middle East time, Israel
launched simultaneous air strikes against all forward
D.A.R. airfields on the Sinai and in the Suez Canal
Zone. While the bulk of the 40o-plane Israeli air force
concentrated on U.A.R. targets, the remaining Israeli
jets made coordinated attacks against airfields in
Jordan, Syria, and Iraq. Israeli raids against Arab air
bases continued throughout 5 June and by nightfall
Israel had complete mastery of the sky having virtually
destroyed four Arab air forces. 13
(8m(J09)ummummF'orty-fiveulninutesmaftel' the la.unchiIlg
of the Israeli air offensive, Israeli troops started their
crushing ground attack against U.A.R. forces in the
Sinai. In the Gaza Strip, Israeli ground forces took
Rafah and Khan Yunus. Meanwhile tank columns
raced thirty miles west into the Sinai to capture Al
'Arish. With this rapid spread of hostilities, NSA
instituted a Si int Readiness Alfa to watch Soviet
'-- ..1moves.
(D) On Tuesday, 6 June, UA.R. President
Nasser, charging that D.S. and British planes had
intervened in the war on the side of Israel, closed the
Suez Canal to all shipping and severed diplomatic
relations with the US. In turn, the US. broke
diplomatic ties with Cairo.
(U) On the battlefield, Israeli tank col-
umns advanced toward the Suez Canal on three major
fronts: through Al 'Arish toward Al Qantarah in the
north; through AbuUwayjilah along the central route
toward Ismailia; and to Al Qusaymah on the southern
route. Farther south, other columns advanced to Al
Kuntillah in the Sinai.
(D) Operating against the Jordanian
forces, Israeli troops captured the cites of Janin,
Qalqilyah, and Ram Allah and took the high ground
north of Jerusalem on 6 June.
(U) On 7 June, Israeli units swept across
the Sinai to advance within eighteen miles of the Suez
Canal in the north and reached toward the Mitla Pass
in the south. Other Israeli forces captured Ash Shar-
mah at the entrance to the Gulf of Aqaba, breaking
the blockade at the Strait of Tiran. Also on the 7th,
Israel gained control of the Gaza Strip plus the West
Bank of the Jordan River. The Jordanian army and
accompanying Iraqi units were defeated.
(D) The United Nations called for a cease-
fire. Israel accepted provided the other belligerents
complied. On 7 June, Jordan agreed to the cease-fire,
but the UA.R. rejected it. The following day (8 June),
however, both the D.A.R. and Syria accepted the
cease-fire. At approximately 1400 hours this same
date the US.S. Liberty was attacked.
(D) On 9 June, following an Israeli charge
that Syria had violated the cease-fire, Israeli troops
and armored forces smashed deep into Syria. By the
time both sides agreed, on 10 June, to observe the
UN. cease-fire, the entire southwestern corner of
Syria was in Israeli hands, including the Golan Heights
which dominated Israeli territory in the Jordan Valley
and around the Sea of Galilee.

Considerations Leading to the Ship's Deployment (U)
(S GGQ) Looking back upon the Liberty inci-
dent today, Americans might well question why the
U.S. introduced an intelligence ship into a war theater
in which Americans were not direct participants and
expose that ship to the risk it did. The decision to
deploy, it should be noted, came before the Six Day
War erupted. It came after careful NSA consideration
of customer requirements for intelligence from this
troubled region, of technical factors which would
govern the collection of Middle East communications,
and of the need to develop technical Sigint data in
the event future U. S. involvement in Middle East
hostilities should bring a requirement to support U. S.
forces. The NSA decision to request the Liberty's
deployment on 23 May, the day it raised its Sigint
readiness condition to Bravo-Crayon, was, moreover,
only one of many actions taken to improve Sigint
collection, processing, and reporting in the critical
weeks before the Six Day War as the NSA action
office, G6, began a round-the-clock Sigint operation at
Fort Meade. I
The Requirements for Intelligence (U)

ligence users for information on a number of military

categories of information they need from Sigint, and
it is up to the Sigint specialists to translate their

('I'S 000) The major part of the U.S. VHF/UHF

specified by NSA. Prior to 23 May, U.S. Airborne

flew some eight sorties a month in the eastern Medi-

collection managers concluded that the then existing
collection organization would be able, at best, only to
make a moderate response to many of the intelligence
requirements in view of technical limitations in the
collection of VHF/UHF communications.
(8 000) In the case of the airborne collectors,
the Sigint planners felt that the average orbit time of
the C-130s and EC-121s - about five hours on station
after allowing for time to and from orbit areas - was
too short for the sustained collection desired.

a possibility, but additional aircraft in sufficient num-
bers would be difficult to obtain, and there was the
consideration of downtime for maintenance which/for
aircraft was greater than for othy Platforms.iS
GGO In the case of the sites, Sigint
planners considered their fixed locations and the
resulting confinement of their VHF/UHF intercept to
line-of-sight distances from those locations. They also
correctly anticipated that, in the event of war, certain
Arab countries would break diplomatic relations with
the U.S. and that,'
000) For consistent, close-in intercept, Sig-
int specialists decided that the assignment of a collec-
tion ship to work..offshore from the U.A.R. was in
order. It was/natural that they would decide upon
shipbomecollection. A technical research ship (TRS)
was, according to one estimate at the time, the
equivalent of 13 airborne collectors and, besides that,
was more economical to operate than the airborne
collectors.'? In addition to tasks such as sustained
collection as in the case of U.S.N.S. Muller
off the shore of Cuba

prepared by design for quick reaction to exigencies of
one kind or another."

narrowed between the U.S.N.S. Valdez I I
then near Gibraltar, and the Liberty in port at
Abidjan, Ivory NSA chose the Liberty because
she had superior speed (18 knots vs. 8 knots for
Valdez), because her VHF/UHF multichannel collec-
tion capability was better, and because she was, unlike
Valdez, at the beginning of a deployment;'? NSA
accordingly requested the Joint ChiefsofStaffiJoint
Reconnaissance Center (JCS/JRC) on 23 May 1967 to
divert the Liberty to the Mediterranean.

Deployment to the Mediterranean (U)
i'St- With Sigint unit USN-855 on board,
the U.S.S. Liberty had been in operation for two years
and four months when NSA sent its message to the
JCS asking for deployment of the Liberty to the
Mediterranean. During this time it had undertaken
I'" ,,".,ate mi"ion, off the ,oo,t 0;
had executed a number of difficult tasks locating

(C-CCO) Other US. Sigint ships at this time
included the U.S.S. Oxford and Jamestown in South-
east Asia, the US.S. Georgetown and Belmont in
South America, the US.N.S. Muller off Cuba, and
the U.S.N.S. Valdez enroute to the US. from the
Mediterranean. I
u.s.s. Modus Operandi (U)
(U) us. reconnaissance operations came
under the purview of the J-3, Joint Chiefs of Staff. A
Deputy Director for Reconnaissance assisted the J-3
in the exercise of operational control over reconnais-
sance activities of the unified and specified commands.
The Joint Reconnaissance Center (JRC) worked for
the Deputy Director for Reconnaissance and had
authority over U.S. reconnaissance operations. NSA
had a representative to the Joint Reconnaissance
Center, Mr. John Connell.
(U) In 1965 the JCS had given general
guidance on the conduct of technical research ship
(TRS) operations. Operational control of the ships was
to be effected by unified and specified commanders
"through the naval component commander to a specific
fleet or force commander." In May 1967, the US. S.
Liberty, an auxiliary general technical research ship
(AGTR) was operating under the control of the Com-
mander-in-Chief, Atlantic. The TRS commanding of-
ficer was Commander William L. McGonagle.
(8-CeO) The JCS also specified that technical
control of Sigint activities \Vasto be exercised by the
Director, NationafBecurity Agency via direct com-
munication to the ships or through the Director, Naval
Security Group. A collection assignment, the JCS
stated further in its 1965 message, would take into
account technical factors as determined by NSA and
safety factors as determined by military operational
(C-CCO) Liberty's Sigint detachment, USN-855,
therefore, came under the technical control of the
Director, NSA and under the management control of
the Director, Naval Security Group. On board the
Liberty, the Sigint detachment was known as the
"Research Department." Its space below decks was
compartmented with access permitted only to staff
having the proper clearances. Commanding officer of
the Research Department was Lieutenant Commander
David E. Lewis. The ship's Captain, Commander
McGonagle, had the clearances needed for access to
the Research Department, visited the department
daily, received briefings, and reviewed the "special
traffic" available there.
(C-CCO) Paddy E. Rhodes, during an interview,
described the area of the Liberty which housed USN-
855: "The research spaces had really three decks. On
the lowest deck we had a training room and a fan
room. The next deck was the R Branch (collection)
spaces, the 0 Branch (communications) spaces, and
processing and reporting. The one above it was T
Branch (other than morse signals)."
"11:0 1. 4 (c)
(U) A small portion of the antenna configuration of the U.S.S. Liberty included:
(34) Discone antenna
(35) Monocone antenna
(36) ECM antenna
(41) VHF-receive antenna
(42) 35' whip antenna
(Figure is UNCLASSIFIED)
(11) Long-wire VLF/LF antenna
(12) ECM antenna
(27) 10' whip antenna
(32) ECM antenna
(33) ECM antenna
1t' Typical of communications arrange-
ments of the AGTR class, the Liberty had circuits for
the ship's command in one location and those for its
Sigint detachment in a separate location. Liberty's
naval communications station, which served the com-
mand, had a "receive" terminal for fleet broadcasts,
three circuits for on-line ship/shore radiotelephone and
voice communications, and one additional orderwire
full-duplex circuit. In a separate location, USN-855
had an on-line, full-duplex radiotelephone circuit, a
secure one-channel moon-relay system - technical
research ship special communications system
(TRSSCOMM) - and a "receive-only" terminal for
fleet broadcasts. In case of need several off-line en-
cryption devices were also available.
(0 000) Sigint collection positions included one
for direction finding, 17 for radiotelephone, 20 for
manual morse, 7 for automatic morse, 7 for electronic
countermeasures, and 33 for non morse search and
development, the latter for frequencies both above
and below 30 Mhz.
(U) Perhaps the most visible technical
feature of the ship was its antennas, some 45 in all.
. (U) Not so visible was, however, the ship's
armament, which was minimal - four .50-caliber
machine guns, 2 forward and 2 aft, one Browning
automatic rifle, and a number of small arms.?

Abidjan to Rota, 24-31 May 1967 (U)
(0 000) The TRS was at Abidjan, Ivory Coast,
at the end of May on its fifth African cruise when, in
response to NSA's message on 23 May, the JCS/JRC,
with approval of the Deputy Secretary of Defense,
directed movement of the ship to the eastern Medi-
terranean via Rota, Spain, and requested the Com-
mander-in-Chief, Atlantic to change operational con-
trol of the ship to the Commander-in-Chief, Europe
upon its arrival at Rota.:' At the time, the Liberty
was under the operational control of the Commander,
Service Squadron 8, a component of the Commander-
in-Chief, Atlantic, and on 24 May the Commander,
Service Squadron 8 issued sailing orders to the Liberty,
with information copies to Commander, Sixth Fleet
and others, directing the ship to move at once to
The Liberty departed Abidjan at 0530Z, 24
May, with estimated time of arrival in Rota, 31 May.s
Lihertyat Rota,
31 May to 2 June 1967 (U)
(V) When the Liberty arrived at Rota on
31 May, it came under the operational control of the
V.S. Commander-in-Chief, Europe (Gen. L.L. Lem-
nitzer) who turned over control to the Commander-in-
Chief, U.S. Navy Europe." While delegating his con-
trol, General Lemnitzer still wanted operational infor-
mation on the ship's progress and asked on 1 June
that situation reports (Sitreps) and planned intended
movement (Pim) reports from the Liberty arrive at
his headquarters daily and that any incidents be
reported as soon as possible in accordance with the
existing reconnaissance reporting instructions.
to-CCO) After taking control, Admiral John S.
McCain, Jr., Commander-in-Chief, U.S. Navy Europe,
directed the Liberty to send to his headquarters daily
Sitreps and position reports and in those reports to
include the Pim for the next 24 hours and any
comments on status of the ship. He directed the
Liberty to depart for the eastern Mediterranean when
ready, provided guidelines for its staying within inter-
national waters, and asked for adherence to estab-
lished communications procedures for the region. NSA
also received the situation reports being required by
Commander-in-Chief, Europe and Commander-in-
Chief, V.S. Navy Europe and used these, along with
ship positions given in Liberty's daily informal tech-
nical summaries, to plot on a routine basis the course
of the Liberty.
(U) At Rota, the Liberty prepared for its
deployment to the eastern Mediterranean, taking on.,
provisrons and fuel, acquiring the military documen-
tation necessary for its assignment to Commander-in-
Chief, U.S. Navy Europe and later to the U.S. Sixth
Fleet, and repairing its TRSSCOMM which had a
faulty hydraulic system.

the missions at hand.
~ C CCG) NSA action officers established a tel-
econ with USN-855 (Lieutenant Commander D. E.
Lewis and his assistant, Lieutenant Maury H. Ben-

(S-CCO) To facilitate the planning for USN-
855's collection mission, Sigint managers had desig-
nated five operational areas numbered west to east in
the eastern Mediterranean near the coastline of the
D.A.R., Israel, Lebanon, and Syria, each measuring
about 5Q-by-50 miles. In proposing the five operational
areas to the JCS, the Director, NSA had indicated
his preference, based on wave propagation analysis of
D.A.R. communications, for operational area three
(32:00-33:00N to 34:00E) if operational and safety
factors did not dictate otherwise. 10 With the territorial
limits established by Middle East countries in mind,
JCS subsequently directed the Commander-in-Chief,
Europe to deploy the Liberty to operational area three
with closest point of approach (CPA) to Algeria, Libya,
and the U.A.R. of 13 nautical miles during transit.
On arrival in operational area three, CPA was to be
12.5 nm to the U.A.R. and 6.5 nm to Israel. II Acting

VQ-2 EC-121 and Air Force's C-130 intercept, which
had increased considerably from the now daily flights
off the Israeli and U.A.R. coastline. The objective was

Communications Station at Asmara, Ethiopia, which
served the eastern Mediterranean. In accordance with
customary communications procedures, the Liberty
would guard the fleetlJroadcast of the Naval Com-
munications Station, Morocco, until it reached the
eastern Mediterranean.
(U) The Commander-in-Chief, U. S. Navy
Europe apprised Commander, Sixth Fleet, Vice Ad-
miral William 1. Martin, on 3 June, that the Liberty's
mission was to conduct an "extended independent
surveillance operation in the eastern Mediterraneair'
and that Sixth Fleet might be called upon to provide
logistic and other support. 17
(U) With the outbreak of the war on 5
June, the Commander-in-Chief, U.S. Navy Europe in
a message to the Commander, Sixth Fleet and others
took note of the movement of some 20 Soviet warships
with supporting vessels and an estimated 8 or 9 Soviet
submarines into the eastern Mediterranean and Ae-
gean and, along with other guidance,instructed Vice
Admiral Martin to keep his ships arid aircraft at least
100 nm away from the coasts of Lebanon, Syria,
Israel, and the U.A.R. and at least 25 nm away from
Cyprus. 1M The Commander, Sixth Fleet directed his
units to comply later/that day.19 Neither the Com-
mander-in-Chief, U.S. Navy Europe nor the Com-
mander, Sixth .Fleet directives included specific in-
structions to.the U.S.S. Liberty.
(0 GOO) Liberty was to the south of Italy when
the Six Day War broke out. With the war's inception,
the Liberty assumed a readiness condition, and USN-
855 began to keep abreast of events from NSA and
field site Sigint Readiness Crayon and other reports
on the Middle East situation and, of course, from its
own intercept. ,0 Members of the USN-855 felt some
apprehension as they approached what they now knew
to be a war zone; they appreciated perhaps more than
before the need for general quarters drills, but they
took comfort from their noncombatant status and, of
course, the visibility of the flag. One USN-855 survivor
recalls being told that" ... if anything were to happen
we were within ten minutes of air strike and help.
None of us were very worried.... "21

bility nor intention to adjudge the safety factors of
the Liberty's mission, in view of the outbreak of
hostilities, NSA's Gene Sheck and Dick Harvey did
te eeej When the TPC became operational on
1 June, the linguists, divided into four operational
shifts, processed the tapes as they were brought into
the TPC compound from the aircraft, and the ana-
lysts/reporters issued their contents with a minimum
of delay as Critics, Spots, electrigrams, or. in the
technical supplements to post-mission flight reports. 13
(8 GGO) On 29 May in a message to USN-855,
the Director, NSA had outlined the mission for the
Liberty during its voyage to the eastern Mediterra-
nean, the changing geographical and hearability con-
siderations to govern specific collection activity during
the trip. The Director, NSA designated USN-855
positions for search and development of Moroccan HF,
VHF, UHF, and radioprinter communications and
Algerian HF, VHF, and possible VHF multichannel
communications. USN-855 was to forward by electrical
transmission technical summaries of Moroccan and
Algerian communications to NSA, with information
copies going tol I
and courier delivery of tapes and traffic to NSA's
Middle East Office, G6.
(8-000) Liberty's move into the Mediterranean
proceeded according to plan. It reported that it
overtook and passed three Soviet ships during its
passage through the Strait of Gibraltar;'? Following
the North African coastline, its collection positions
were on the prescribed Algerian and Moroccan com-
munications. Orientation and training for the main
objective, U.A.R. communications, detracted some-
what from performance on the secondary Algerian and
Moroccan assignments, but this was to be expected. 16

ask the NSA liaison officer to the JCS/JRC, Mr. J.
Connell, on 5 June if any consideration was being
given there to a change in the Liberty's operational
area. They reminded Connell that during the 1962
Cuban missile crisis five years earlier the V.S.S.
Oxford had been pulled back from the Havana area.
The NSA concern was for the technical collection
arrangements which would have to be adjusted if the
Liberty was to be withdrawn. The NSA liaison officer
discussed the matter with JRC's ship-movement officer
and then advised Sheck and Harvey that no action
was then under consideration. 22
(V) On 6 June, as it was passing between
Libya and Crete, the Liberty reported to Sixth Fleet
that its TRSSCOMM, which had had malfunctions in
its power supply and hydraulic systems on the trip
from Rota, was again operating satisfactorily and, in
reply to a Commander-in-Chief, U.S. Navy Europe
query concerning Pims not being received, provided
the date-time group of Pims previously sent.
VSN-855's communications on the 6th
to NSA were normal - its 24-hour summary for 5
June, its informal technical summary no. 3, a Spot
Ireport, its follow-up to I
and other reports all being received without commu-
nication difficulties. It was also in satisfactory com-
munication lin this period. 23
(V) On this same day, 6 June, the Com-
mander-in-Chief, U.S. Navy Europe told the Com-l
mander, Sixth Fleet that the Liberty was to come
under his operational control at OOOl.Z, 7 June 1967
in order "to facilitate area command and control and
any possible requirement for protection during the
Middle East hostilities" and pointed \.out that the
Liberty's schedule might be revised for safety reasons
"as dictated by the local situation. ,,24 Libert y acknowl-
edged the instructions concerning its operational con.
trol at 2036Z on the 6th. Liberty's commanding
officer, Commander McGonagle, also told\\ the Com-
mander, Sixth Fleet that the ship was in a "Readiness
Condition Three-Modified" and reminded his superior
that the ship's "self-defense capability" was limited
to four .50-caliber machine guns and small arms.
(V) Three hours later the Commander,
Sixth Fleet cautioned its new charge by message to
"maintain a high state of vigilance against attack or
threat of attack" in view of the "unpredictability of
V.A.R. actions." He directed the Liberty to report by
Flash precedence any threatening actions orrany
diversion from schedule necessitated by
threat" and to submit "reports of contact with ship$,
aircraft, and submarines which are unidentified, df
intelligence interest, or engage in harassment." Ad-
miral Martin also instructed the Liberty to copy the
fleet broadcast and to use his fast carrier task force
(TF-60) tactical circuits if necessary." Liberty did not
receive, for one reason or another, this message. 26
(V) On 7 June at 0800Z the Liberty was
off the coast of the V.A.R. and approaching opera-
tional areas two and three. Despite the Immediate
Precedence assigned to the Liberty's Sitrep/Posit re-
port at 0908Z, 7 June, giving its position at 0800Z at
33-06N 28-54E, it took, according to a JCS postmor-
tem report, some fifteen and one-half hours for the
Liberty's position report to reach the Commander,
Sixth Fleet, the action addressee.r ' Liberty was now
guarding the fleet broadcast of the Naval Communi-
cations Station, Asmara. On this day a number of
actions were under way to minimize the appearance of
U.S. involvement in the Middle East hostilities and
to change the Libert's 0 erational area.
In a message to the Commander, Sixth
Fleet, the JCS took note of new V.A.R. allegations,
possibly derived in JCS's opinion from the V.A.R.'s
I Ito the effect that U. S. personnel
were in communication with Israel and were possibly
providing military assistance. Equally concerned about
the earlier U. A. R. allegations that U. S. aircraft had
participated in the Israeli air strikes against the
U.A.R., the JCS asked for assurance from Vice Ad-
miral Martin that his aircraft were not within 200
miles of the U. A. R., Syria, or Israel and that there
were no Sixth Fleet communications or other contacts
with Israel. 19 The Commander, Sixth Fleet replied
negatively, observing only that radio voice circuits had
been established with the American Embassy in Tel
Aviv and that transmissions so far had only been for
testing purposes. 30
(8 eeO) Studying the successful Israeli drive
into V.A.R. territory, the Director, NSA decided that
the Liberty's opportunity for effective collection of
EO 1. 4 . (c)
U.A.R. communications might best take place in
operational area two to the west of the originally
specified area three. The Director, NSA asked at
2104Z that the JCS/JRC change the Liberty's schedule
"to satisfy technical requirements." Since this request
reached the JCS/JRC as the latter was having second
thoughts about the Liberty, no action would be taken
on the NSA request.
Directions to Withdraw the Liherty (U)
(0 000) In view of the sensitivity regarding the
U.A.R. charges of U.S. complicity with Israel and
following a question from the US. Chief of Naval
Operations about the wisdom of Liberty's assignment
in the war zone;" the JCS/JRC made a new assessment
of the danger inherent in the Liberty's operations.
JRC considered the distance of the Liberty from the
Sixth Fleet, some 300 to 400 miles. After it learned
from NSA the degree to which the collection mission
would suffer if the ship's CPA was changed;" JRC
decided to accept the mission degradation. At the
time of these deliberations - 2300Z, 7 June - the
Liberty arrived on station in operational area three.
(U) In a message conveying the sense of
urgency then developing in the Pentagon staff, JCS
expressed concern in a message at 2230Z to Com-
mander-in-Chief, Europe over the Middle East situa-
tion and stated that the JCS-directed operational area
for the Liberty was "for guidance only" and could be
"varied as local conditions dictate." JCS also in-
structed the Commander-in-Chief, Europe to change
CPA to the U.A.R. to 20 nm, to Israel 15 nm.
Although a copy of the message was to have gone to
the Liberty, it would not reach the ship prior to the
attack. The Department of Army Communications
Center in error sent it to the Naval Communications
Station in the Pacific. 34
(U) Further deliberation within the JCS/
JRC following discussions with the Chief of Naval
Operations, who was pressing for a 100-mile CPA for
the Liberty, now resulted in a JCS decision to move
the Liberty well off the hostile shoreline. Contributing
to the decision, as JRC's Captain Merriwell Vineyard
(USN) told NSA's JRC representative, John Connell,
late on the 7th, was the desire of General Wheeler,
Chairman, JCS, to support in any way the US.
position taken at the UN. in answer to U.A.R. charges
of complicity. U.S. Ambassador Arthur J. Goldberg
had stated on the 6th to the Security Council that
"All Sixth Fleet aircraft are and have been several
hundred miles from the area of conflict."
(U) At 2350Z, one hour after the JCS had
given its instructions restricting the Liberty to the 15-
20 nm CPA, JRC's Major Breedlove, skipping normal
Commander-in-Chief, Europe channels, on Yocom
called Commander-in-Chief, U.S. Navy Europe's com-
mand center to convey the JCS/JRC decision and to
direct that the Liberty be moved back to a CPA of
100 nm to the coasts of Israel, U. A. R., and Syria and
a CPA of 25 nm to Cyprus. He indicated to Lieutenant
E. L. Galavotti, the operations duty officer there, that
a confirming JCS message would follow. Breedlove
explained the urgency of the matter "because time
[was] getting short to where she will be in those
limits." Galavotti said he would go to Sixth Fleet right
away and had an appropriate message ready by
080001Z for release by his superiors to Sixth Fleet.
Some fourteen minutes after calling Commander-in-
Chief, U. S. Navy Europe, Breedlove called the Com-
mander-in-Chief, Europe JRC watch officer, informing
him of the verbal request to NAVEUR and telling him
that NAVEUR had promised to take action. 35
(U) Within the Commander-in-Chief, U.S.
Navy Europe command center, an unfortunate delay
took place, however, in relaying this JCS/JRC instruc-
tion to the Sixth Fleet for action. Mindful that this
directive had skipped channels and was only verbal,
Galavotti's superior, Captain M. J. Hanley, Jr., Dep-
uty Chief of Staff, U.S. Navy Europe, directed that
the message to Sixth Fleet not be released until the
date-time group of the JCS confirming message was at
hand. NAVEUR policy allowed for acceptance of oral
instructions from higher headquarters to move ships
and aircraft only if given by flag or general officers or
if firm evidence of a message directive were provided
- for example, the date-time group of a confirming
message. Instead of releasing the message, Captain
Hanley told the NAVEUR command center duty
officer, Commander C. G. Jorgensen, to apprise Com-
mander-in-Chief, Europe of the matter and ask that
headquarters to obtain the date-time group of the
confirming JCS message. Jorgensen then called the
US. European Command's (EUCOM) command duty
officer at 080030Z, who indicated he would check and
call back. The JCS confirming message, JCS 08011 OZ
was, of course, not yet released at the time of the
call. Its transmission by the Department of Army
Communications Center in the Pentagon to Com-
mander-in-Chief, Europe was at 080211Z.
(U) Not hearing from the higher head-
quarters, Commander Jorgensen repeated his call at
0325Z on 8 June to check again on the status of the
action and again asked EUCOM to obtain a date-time
group, this time speaking with a duty officer in the
JRC section of EUCOM, Lieutenant Colonel C. K.
Russell. European Command's delay of three hours in

The Liberty would not receive the critical message in
preparations on board the D.S.S. America for a press
conference relating to the U.A.R. charges of V.S.
complicity with Israel in the prosecution of the war
and to Sixth Fleet's need to transmit other traffic of
equal or higher precedence.r" Meanwhile Liberty was,
of course, already in its operational area. Its position
at 080800Z was within 30 nm of 31-45N 33-30E in
area three.
(V) When it rains, it pours, and there
would be even further delays in the attempts to get
the word to the Liberty.
(V) JCS's investigating team, the U.S.
Navy Court of Inquiry, and later a congressional staff
gave close attention to the Sixth Fleet message to the
Liberty, following the status of the message in the
critical hours before it came under attack. Essentially,
the findings were these:
responding to NAVEUR had resulted from its assump-
tion, based on Breedlove's call from the JCS/JRC,
that NAVEUR was already taking action. 37 Shortly
thereafter, Russell was able to give Jorgensen the
required JCS date-time group, the message having
just arrived in the EVCOM JRC duty officer's hands,
but this was about the same time as NAVEUR's
information copy of JCS 080110Z, the confirming
message, arrived in the NAVEUR command center
itself - the time, 0325Z, 8 June. A precious four
hours had gone by since Major Breedlove's call.
(V) Commander Jorgensen then asked for
a telecon with Sixth Fleet's staff duty officer and at
080355Z was experiencing difficulties in establishing
contact because of atmospheric conditions. He then
had his radio operator contact Sixth Fleet lAy single
sideband radio and request the telecon as soon as
possible. The two-way telecon with Sixth Fleet began
at 080410Z.
(D) When the Sixth Fleet staff duty officer
told Jorgensen his command did not have JCS 080110Z
as yet (the Army Communications Center, Pentagon,
having misrouted this message to Hawaii), Jorgensen
passed it to him three times before gaining an ac-
knowledgement at 080440Z from the Sixth Fleet's duty
officer, who was having difficulty in hearing NAVEUR.
Jorgensen then sent a confirming message: "From
CINCNAVEDR Command Duty Officer to COM-
SIXTHFLT Duty Officer. Be advised that JCS 0801lOZ
FORAC. Official msg follows."
(V) Ironically, the Sixth Fleet's duty offi-
cer then indicated to Jorgensen that Sixth Fleet did
not hold reference (a) on the critical JCS message and
asked for a copy. Since NAVEUR also was without a
copy of the referenced message, despite both NAVEUR
and Sixth Fleet's having been designated for infor-
mation copies (JCS 7337/072230Z), Jorgensen would
obtain it from Commander-in-Chief, Europe and later,
on obtaining a copy, outline to the Sixth Fleet's duty
officer its contents which had, by that time, been
overtaken by events.
(D) From 080440Z June 67 it became the
Commander, Sixth Fleet's responsibility to direct the
Liberty to a safer area of operations than the one in
which she was then steering. Vice Admiral Martin's
message to the Liberty, directing it not to approach
the coast of the D.A.R., Syria, or Israel closer than
100 nm, went out some four and one-half hours later,
at 080917Z, the delay in this case being attributed to
0630Z, 8 June

giving action on the JCS message to NAVEUR. Infor-
mation copies of the JCS and the CINCEUR action
messages were to have gone to the U.S.S. Liberty,
and it is, of course, entirely possible that timely
receipt of these might have triggered a withdrawal
action on the part of the Liberty's Commander Me-
Gonagle. But the same unkind fate guarding the action
messages was also looking after the information copies.
These too ran into communications problems of one
kind or another, and the Liberty would not receive
them. 39
Operational Area Three, 8 June (U)
(8 eeO) Once on station off Port Said in oper-
ational area three, USN-855 employed its collection

Icommunications I
i'Sf3t- The Liberty had no specific assign-
ment to intercept Israeli communications while it was
in operational area three. Omission of this tasking
was, in part, owing to the lack of Hebrew linguists.
But on the morning of 8 June its VHF search positions
did produce three tapes of Israeli air traffic. The
contents were, as determined later, routine operational
messages. As a by-product of searching for U.A.R.
communications in the Sinai, USN-855 also identified
some 22 frequencies as Israeli, but again there was
nothing relatable in any way to the forthcoming
Lihertys Processing Mission (U)
(8 eeO) On station in operational area three,
USN-855's processing and reporting constituted a
complex undertaking. It was to provide daily technical
summaries for use by other collectors and NSA,
enabling them to remain up to date on the Liberty's
operation. Upon completion of its deployment, USN-

Chapter IV
The Attack (U)
(U) Thursday morning, 8 June 1967, found
the Liberty cruising slowly in international waters on
station as directed. At approximately 0830 hours (local
time), the Liberty notified the Commander, Sixth
Fleet that her position for the next 24 hours would be
within 30 nautical miles of coordinates 31-45N and
33-30E.I The sea was calm and the clear sky permitted
visibility of ten miles; a light breeze ruffled the
Liberty's ensign.
(U) Liberty's projected course for that day
was to proceed to a point 13 nautical miles from the
U.A.R. coast at 31-27.2N, 34-00E (Point Alpha),
thence to 31-22.3N, 33-42E (Point Bravo), thence to
31-31N, 33-00E (Point Charlie) retracing this track
until new orders were received. Normal steaming speed
was to be five knots and typical steaming colors (which
indicated conditions were normal) were flown.
"condition of readiness three, modified" was set; i.e.,
a normal steaming watch, except that one man was
stationed at each of the forward two .50-caliber
machine guns, numbers 51 and 52. Lookouts on the
bridge were designated to man machine guns 53 and
54 just aft of the bridge, in the event of a surprise air
or surface attack."
(U) At about 0930 hours, it was possible
to visually sight the minaret at Al 'Arish on the
U.A.R. coast. This was used as a navigational aid and
the ship's position was verified as being within its
operating limits. There were no other conspicuous or
outstanding navigational features in the area."
Reconnaissance of the Liberty (U)
(U) Shortly before 0900 hours (Iocal time),
two delta-wing, single-engine jet aircraft orbited the
Liberty three times at 31-27N, 34-00E. The planes'
altitude was estimated at 5,000 feet, at a distance of
approximately two miles. Liberty notified the Com-
mander, Sixth Fleet and others of this reconnaissance,
stating that identification was unknown and that no
amplifying report would be submitted.
(U) Later in the morning, at 1056 hours,
an aircraft similar to an American flying boxcar
crossed astern of the Liberty at a distance of about
three to five miles. The plane circled the ship around
the starboard side, proceeded forward of the ship and
headed back toward the Sinai peninsula. This recon-
naissance was repeated at approximately 30-minute
intervals. It was impossible to see any identifying
markings on the aircraft. The plane never approached
the Liberty in a provocative manner and made no
attempt to signal the ship. Nor did the Liberty
attempt to signal it. 7 Subsequent investigations of the
attack on the Liberty identified the aircraft as a
French-built Noratlas NORD 2501, piloted by Israeli
Air Force.
-tet" Though this plane was unidentified,
the thoughts of Robert L. Wilson (one of three NSA
civilians aboard the Liberty) must have been shared
by his shipmates. Wilson remembered thinking when
he saw the plane, that "it must be Israeli because
what else is flying out here at this point in the war
and also it's coming from the direction of Israel and
it's going back to Israel, so it was obvious that it was
Israeli. I didn't think much of it. They were just out
there checking us out. That's what I would do tOO.,,8
(V) Being sensitive to its exposed and
unprotected position, the Liberty reported to the
Naval Security Station Command, at approximately
1100 hours, that she had destroyed all superseded
May publications (e.g. crypto documents) and intended
to destroy all irregularly superseded material daily
because of the "current situation and shallow water in
operating area.""
General Quarters Drill (U)
(V) After the lunch hour, at 1310 hours,
the Liberty's crew was exercised at general quarters
for drill purposes for a mandatory noncompetitive
exercise to train the crew in chemical-attack proce-
dures. This was a routine activity, part of the ship's

training program established by the Commander, Ser-
vice Force, Atlantic Fleet, and was not related to her
mission in the eastern Mediterranean. The drill was
performed satisfactorily and the ship returned to her
"modified condition three" at 1345. LO
(U) Following the general quarters drill,
the Liberty's Commanding Officer, Commander Wil-
liam L. McGonagle, fixed her position by radar as
being 25.5 nautical miles from the minaret at Al
'Arish, which was to the southeast (bearing 142
Air Attack Begins (U)
(8 000) Amidships below deck, the Liberty's
Research Department (the Sigint collection, process-
ing, and reporting area) resumed normal operations.
Robert L. Wilson was in the analysis/reporting area
together with the other civilians, Allen M. Blue and
Donald L. Blalock, plus the Marine linguists. Things
had been slow and Wilson considered going up on deck
to do some sunbathing but changed his mind. Com-

That far below deck it was diffi-

(U) During the general quarters (GQ)
drill, Lieutenant James G. O'Connor (Assistant Tech-
nical Operations Officer of the Research Department)
had been officer of the deck on the bridge. At the
conclusion of the drill, he went up to the 04 level
(above the bridge) to see if he could locate the
approaching airplanes that had been picked up on
radar by the lookouts. It was 1400 hours. From the
starboard wing of the bridge, Commander McGonagle
observed a single jet aircraft that appeared similar, if
not identical, to those that had been sighted earlier
in the day and about which a sighting report had been
submitted. The relative bearing of this plane was
about 135
, its position angle was about 45
, its
elevation approximately 7,000 feet, and it was approx-
imately five to six miles from the ship. It appeared to
McGonagle that the plane was traveling parallel to,
and in the same direction as the Liberty. With his
binoculars trained on the aircraft, the Commander
was unaware of a second plane swooping in from the
port side to launch a rocket directed toward the
bridge. When the rocket exploded two levels below the
bridge, McGonagle ordered the general alarm to be

Commander had ordered the whaleboat engine tested
and, when Dusty heard a muffled explosion, he
thought, "Those damned deck apes blew that boat up
and I've got to go back up and fight the fire."
Simultaneously, Dusty heard the general quarters
alarm. Scampering back up the ladder, he could smell
burning powder and started "dogging down" doors
when a rocket tore through a bulkhead to his right
ripping steel all about.

(U) Down in the Research Department,
Terry McFarland, wearing his headphones, was va-
guely aware of flickers of light coming through the
bulkhead. He didn't realize that these were armor-
piercing tracer bullets slicing through the Liberty's
skin. The "flickers" were accompanied by a strange
noise that sounded to Terry like chains being pulled
across the bottom of the ship. Next, he saw Seaman
"Red" Addington race down the ladder from above
with blood running down his right leg from a wound in
the knee. "Somebody's up there shootin' at us," said
Red. Nobody spoke, but Terry could see the fear in
the faces about him. Someone ordered the men to
perform emergency destruction, and they turned to
dumping classified material in the weighted, white
canvas bags specially made for this purpose. Robert,
L. Wilson went up to the second deck from the
processing and reporting (P&R) spaces to empty safes
on that upper level.
(0 eeS) Hearing the general quarters alarm,
CT3 Clyde W. Way ran from the mess deck to his
station in the T-Branch spaces one deck above the R
Branch. Way plugged in his radio receivers and heard
nothing; he called the R2 area only to learn that their
reception had also gone dead.
(U) Topside, one level above the main
deck, the exploding rocket had started a blazing fire
in two 55-gallon gasoline drums stowed below the
bridge on the port side. McGonagle quickly ordered
his Executive Officer, Lieutenant Commander Philip
M. Armstrong, to go down and release the gasoline
cans. Lieutenant O'Connor joined the Exec. Just as

both reached the top of the ladder to proceed down,
a bomb hit near the whaleboat on the starboard side,
immediately aft of the bridge. Armstrong and O'Connor
were thrown back onto the bridge and other personnel
in the pilot-house were blown from their feet. Mc-
Gonagle grabbed the engine order annunciator and
rang up all head flank speed - an order for maximum
speed. At the same time, he ordered Lieutenant
Maurice H. Bennett to report to the Chief of Naval
Operations (CNO) via the high-command radio circuit
(hicom) that the Liberty was under attack by uniden-
tified jet aircraft and required immediate assistance.
This Flash message, giving the Liberty's position as
33-25E, 31-23N, was received by the aircraft carrier
V.S.S. Saratoga (CVA-60) and relayed to Commander,
V.S. Naval Forces Europe; Commander, Sixth Fleet;
and Commander, Task Force 60 (CTF 60).ll Liberty's
transmission was not made without difficulty. During
the attack and intermittently thereafter, the hicom
voice circuit was subjected to loud jamming regardless
of frequency. This electronic interference was de-
scribed as a steady carrier without modulation.'?
(V) After being blown back onto the bridge
floor, Lieutentant O'Connor realized he had no feeling
in his body from the waist down. To get out of the
way, he dragged himself into the combat information
center (CIC) behind the bridge, where several others
had also sought safety. Lying face down, O'Connor
soon noticed that there was a lot of blood on the floor
and then realized it was his. About this time, Ensign
O'Malley stepped into the CIC and helped stop
O'Connor's bleeding by stuffing a T-shirt into the holes
in his back.
(V) A few moments after the bomb blast
on the starboard side, Commander McGonagle was hit
by flying shrapnel and knocked off his feet, but, though
shaken up, he remained on the bridge, totally in
(V) For the next five or six minutes, air-
craft made criss-cross attacks on the Liberty at about
one-minute intervals, hitting her with rockets and
machine-gun fire. A final count entered into the Court
of Inquiry's record, showed 821 separate hits on the
ship's hull and superstructure. The attacking aircraft
were later identified as French-built Dassault Mirage
jet fighters whose armament consisted of two 30mm
cannon, two 1,000-pound bombs, and four rocket pods
(18 rockets each).
(V) During the first or second strafing run,
the ship's public-address system, the electrically pow-
ered intercom system, and most sound-powered phone
circuits were severed or destroyed.
(V) In the first minutes of the air attack
the Liberty suffered a complete loss of external com-
munications because of badly damaged radio trans-
mitting equipments and antenna systems. In spite of
this, emergency restoration of hicom voice capability
was completed within minutes. All U.S.S. Liberty
communications immediately thereafter were via the
hicom voice network."
(V) The coordinated strafing, rocket, and
incendiary air attacks created three major fires topside
that covered large areas of the Liberty with flames
and heavy smoke. Eight men were killed or died of
injuries received during the air attack: two killed or
mortally wounded on the bridge, two killed at machine
gun 51, one killed at machine gun 52, one died from
wounds received on the main deck starboard side, and
two died of wounds received on the 01 level portside.
Throughout the topside area, 75 men had been
wounded by shrapnel and shock of exploding rockets.
(V) During this period, the Liberty grad-
ually built up speed from five knots; her exact speed
was not known but it is doubtful that she exceeded 11
or 12 knots while under attack.
Torpedo-Boat Attack (U)
(V) At about 1424 hours, look-outs sighted
three high-speed boats approaching the Liberty from
the northeast on a relative bearing of approximately
at a distance of about 15 miles. The boats
appeared to be in a wedge-type formation, spaced
about 150 to 200 yards apart, and closing in a torpedo-
launch attitude at an estimated speed of 27 to 30
knots. Commander McGonagle ordered a sailor from
the bridge to man the starboard gun and take the
boats under fire. Using the hicom circuit, the Liberty's
radioman reported the approach of the torpedo boats.
This was received and relayed by the V. S. S. Saratoga
to Commander-in-Chief, V.S. Navy Europe and to the
Commander, Sixth Fleet. 14
(V) It was then that the Commander no-
ticed that the Liberty's American flag had been shot
down. He immediately ordered a signalman to hoist
the "holiday ensign" - the largest flag aboard (ap-
proximately 7 x 13 feet) - from the yardarm, the
normal flag halyard having been destroyed. There was
smoke from the burning whaleboat and other topside
fires in the vicinity of the bridge.
(V) Commander McGonagle passed the
word, "Stand by for torpedo attack." He held his
course, since turning away from the boats would bring
the ship closer to land, and turning toward them would
swing the ship broadside toward the attackers, giving
them a larger target.
(U) When Robert L. Wilson heard the
torpedo attack warning, he remembered one of the
seamen telling him to sit on the floor and brace his
feet against the wall.
(U) In the processing and reporting area,
CT Terry McFarland was told to "tuck pant legs into
your socks, button top collar, get rid of loose material,
and lie flat on floor and hold your head in your hands
to protect your face."
(0) When the motor torpedo boats were
approximately a mile away, the center boat was seen
flashing a signal. light. Because of smoke and flames
in the direction from which the boats were approach-
ing, Commander McGonagle could not read the signals,
but he saw what he believed to be an Israeli flag. As
the air attack had knocked out the Liberty's starboard
signal light, he attempted to signal with a hand-held
Aldis lamp. This may not have been powerful enough
to penetrate the smoke pouring from the fires started
by the attackers. Believing that the air attack might
have been in error, Commander McGonagle quickly
shouted to the starboard forward gun to withhold fire.
The gunner fired a short burst at the motor torpedo
boats before he understood the CO's order. At the
same time, though unattended, the after gun on the
starboard side opened fire: flames from the burning
whaleboat had ignited bullets in the gun and in the

done to one of the two forward area 50-caliber
gun mounts.

ammunition box, causing the gun to fire in the
direction of the attacking boats.
(U) At this time, the motor torpedo boats
opened fire with their gun mounts, killing the Liberty's
helmsman. In a matter of seconds one torpedo crossed
astern of the ship at about 25 yards. The time was
then 1434 hours. A minute later, a second torpedo
struck the ship on the starboard side, just forward of
the bridge and a few feet below the water line. Again,
using the hicom net, the Liberty broadcast that the
ship had been torpedoed and was listing badly. The
Saratoga picked up the transmission and relayed it to
the Commander-in-Chief, V.S. Navy Europe and to
the Commander, Sixth Fleet. 15
(U) To Lieutenant O'Connor, lying on the
floor of the combat information center, the torpedo's
deafening explosion seemed to lift the ship right out
of the water, and when it settled back he thought it
was going to roll over.
(V) In the Research Department where
the torpedo struck, everything went black; oil and
debris were everywhere. Water rushed in and equip-
ment fell over Terry McFarland, but he managed to
keep clear and make his way in the darkness to the
ladder to go topside. When he got out there was about
a foot and a half of air space left.
(U) CT Clyde W. Way was in T-Branch
spaces above the processing and reporting area. With
the explosion below, all equipment fell to the floor and
smoke poured from the P&R hatch. Way started
pulling men out as they came up the ladder. There
was no panic. A Marine went down the ladder to help
locate men possibly trapped in the water. As the water
rose in the Research Department, Lieutenant Maurice
Bennett realized that he had to close the hatch to
contain the flooding. Attempts to contact the Marine
who had gone back failed, and Lieutenant Bennett
reluctantly and sorrowfully ordered the hatch closed.
McFarland and Way then went topside to help fight
fires and attend the wounded.
(U) The torpedo explosion had torn a hole
in the side of the ship that extended from a few feet
above the water line to below the turn of the bilge. It
was shaped like a tear-drop, and was 39 feet across at
its widest point. Its immediate effect was to flood all
compartments on two decks below the water line, from
frame 53 to frame 66. These frames supported water-
tight bulkheads, and marked the location of the
Liberty's Research Department and store rooms.
Twenty-five men died in these spaces some from the
blast, others drowned.
(U) The torpedo hit did not start a major
fire, probably because of the immediate flooding of the

affected area, but the Liberty immediately listed nine
degrees to starboard. Power and steering control were
lost temporarily and the ship came dead in the water.
The time was 1440 hours.
(D) The three torpedo boats also stopped
and then milled around astern of the Liberty at a
range of approximately 500 to 800 yards. One of the
boats signaled by flashing light, in English, "Do you
require assistance?" Not being able to signal by light,
Commander McGonagle ordered a signalman to hoist
the international flag signal for "not under command,"
meaning that the ship was maneuvering with difficulty
and that they should keep clear. One of the torpedo
boats was identified by a hull number of 204-17. All
boats retired toward shore at 1505 hours. The attack-
ing torpedo boats were later identified as French-built
motor torpedeo boats of the Israeli Ayah class. These
were 62-ton craft, capable of 42 knots, with a crew of
15 and armament consisting of one 40mm cannon,
four 20mm cannon, and two torpedos.
Post-Attack Reconnaissance (U)
(D) At about 1515 hours, two helicopters
approached the Liberty and circled around the ship at
a distance of about 100 yards. The Star of David
insignia was clearly visible. One of the helicopters was
numbered 04 or 04, the other 08 or 08. The helicop-
ters departed, returned, and departed again.
(D) Commander McGonagle designated the
mess decks as a casualty collection station, and the
wounded were taken there by repair party personnel
and other crew members able to assist.
(D) Reports received from damage control
central indicated that the flooding was under control.
Power was restored to the bridge at 1520 hours, but
steering control could not be regained from the bridge,
making it necessary to give rudder orders by telephone
to men in the "after steering" compartment, and for
some time they operated the ship's heavy rudder by
(D) At 1536 hours, the Israeli torpedo
boats again approached the Liberty from the star-
board, at a range of five miles. During the next hour
and a quarter, the boats returned toward the ship
several times before disappearing over the horizon
without further signal or action.
(D) Communications were restored at
about 1600 hours, and Commander McGonagle dic-
tated a message to Lieutenant Bennett providing
additional information concerning the attack by un-
identified aircraft and the fact that the torpedo boats
had been identified as Israeli. A preliminary estimate
of the number of dead and casualties, as well as the
condition of the ship, was also provided. Transmission
of this message was delayed because shipboard emer-
gency measures demanded immediate attention to
preserve the safety and stability of the ship and
minimize new casualties.
(D) Fifteen minutes later two unidentified
jet aircraft approached the Liberty from the starboard
side and reconnoitered from a distance before disap-
pearing from the scene.
Sixth Fleet Reacts (U)
(D) Aboard his flagship, the guided-missile
light cruiser U. S. S. Little Rock (CLG-4), the Com-
mander, Sixth Fleet received (from the Saratoga) the
Liberty's messages about the air and torpedo boat
attacks. At 1450 hours, fifty minutes after the attack
began, he ordered the aircraft carrier U. S. S. America
(CVA-66) to launch four armed A-4 Skyhawks and the
carrier U.S.S. Saratoga (CVA-60) to launch four
armed A-1 attack planes to defend the Liberty. The
America was also directed to provide fighter cover and
tanker aircraft to refuel the fighters, if necessary. 16
At this time, the Sixth Fleet was located south of
Crete, approximately 450 miles west of the Liberty.
(D) At 1516 hours, Commander, Task
Force 60, implemented Sixth Fleet's directive and
instructed his carrier pilots to "destroy or drive off
any attackers who are clearly making attacks on the
Liberty. Remain over international waters. Defend
yourself if attacked." 17
(U) On the heels of this action, at 1520
hours, the Commander, Sixth Fleet, informed U. S.
Commander-in-Chief, Europe (CINCEUR) of the at-
tack and aircraft being deployed to defend the Liberty.
It was estimated that the first aircraft would be on
the scene at 1715 hours."

(U) Following this, at 1549 hours, the
Commander, Sixth Fleet relayed to the Chief of Naval
Operations (CNO) and the Commander-in-Chief, U.S.
Navy Europe, (CINCUSNAVEUR) his message of
instruction to the carriers concerning the use of force
and observance of Israeli and Egyptian territorial
limits. 19
(U) Commander, Task Force 63, reacting
to the Liberty's plight, sent a message to Sixth Fleet
at 1610 hours recommending that fleet ocean tug

diverted to proceed at maximum speed to assist the
Washington Informed (U)
(U) An hour and eleven minutes after the
Liberty was attacked, the National Military Command
Center (NMCC) in the Pentagon was phoned by
CINCEUR and told of the situation as known. At 0915
hours (DST), 8 June, NMCC phoned the NSA Sigint
Command Center to notify NSA of the attack. 20
(U) At the White House, President Lyn-
don B. Johnson was busy telephoning cabinet members
and congressional leaders when he was interrupted at
0949 hours (DST) by Walt Rostow, his Special Assist-
ant for National Security Affairs, and told that "the
Liberty, has been torpedoed in the Mediterranean.
The ship is located 60-100 miles north of Egypt.
Reconnaissance aircraft are out from the 6th fleet .
... no knowledge of the submarine or surface vessel
which committed this act.... shall keep you informed.Y"
(U) Rostow phoned again at 1014 hours to
advise the President that the Liberty was "listing
badly to starboard. The Saratoga has launched 4-A4's
and 4-A1's.... ,>22
Israel Reports Error (U)
CU) In Tel Aviv, Israel, the U.S. Naval
Attache, Commander E. C. Castle, was called to the
Foreign Liaison Office, Israel Defence Force at approx-
imately 1600 hours (local time) and told that Israeli
air and sea forces had attacked the Liberty in error.
Immediately the U. S. Defense Attache office sent a
Flash message to advise the White House, Department
of State, and others of this development. 23
Johnson Informs Kosygin (U)
CU) The message was received by the
White House, NMCC, and other members of the U.S.
military and intelligence community at 1045 hours
CDST). Walt Rostow informed the President and
immediately drafted a "hot line" message to the
Kremlin. President Johnson approved the following
text which was sent to Chairman Kosygin at 1117
hours (DST):
We have just learned that U.S.S. Liberty, an auxiliary ship,
has apparently been torpedoed by Israel forces in error off Port
Said. We have instructed our carrier, Saratoga now in the
Mediterranean to dispatch aircraft to the scene to investigate.
We wish you to know that investigation is the sole purpose of
this flight of aircraft, and hope that you will take appropriate
steps to see that proper parties are informed. We have passed
this message to Chernyakov but feel that you should know of
this development urgently. 24
The message was received in Moscow at 1124 hours
CDST).25 At 1210 hours Kosygin replied by "hot line"
that he had passed the message to President Nasser
of Egypt.
Thereafter instructions were issued by JCS
and Commander, Sixth Fleet to withdraw the aircraft
launched to defend the Liberty. By 1849 hours Sixth
Fleet reported all planes recalled and accounted for. 27
(U) Deputy Secretary of Defense Vance
notified the Commander-in-Chief, U.S. Navy Europe,
by phone at 1700 hours that all news releases on the
Liberty affair would be made at the Washington level
- no releases were to be made aboard ships. This
information was relayed to the Commander, Sixth
Fleet. 28
Libert}' Recovers (U)
CU) Unaware of what was happening at
fleet headquarters or in Washington and Tel Aviv, the
Liberty was struggling to regain full engine power and
to reach deeper water. The gyro compass was out but
the pilot-house magnetic compass appeared to be
(U) The ship remained at general quarters
while the crew effected post-attack emergency meas-
ures. Sixth Fleet was notified that the Liberty had
carried out the emergency destruction of all crypto
publications and key cards. Her only means of com-
munication remained the hicom circuits. 29
(U) Liberty's medical officer, Lieutenant
Richard F. Kiepfer, Medical Corps, USN, performed
one major operation and gave emergency treatment to
wounded men as best he could. He manned the main
battle dressing station, together with one hospital
corpsman, while the other corpsman operated a sec-
ondary station in the forward part of the ship. Both
stations were flooded with seriously injured men and
for a time there was little opportunity to do more than
give first aid. Bleeding was stopped, men were given

morphine for pain and treated for shock, and those
with lung wounds were treated to ease breathing.
(U) At 1750 hours, Sixth Fleet advised the
Liberty that destroyers were on the way at maximum
speed and that the Liberty was to proceed on a course
of 340

u.s. Naval Attache Helicopters to
the Lihert)' (U)
(U) Back in Tel Aviv, the Israeli Foreign
Liaison Office was arranging for a helicopter to fly
Commander Castle, U.S. Naval Attache, to the Lib-
erty so that he might communicate with its command-
ing officer. The helicopter left Dov Hoss (now Sde-
Dov) airfield on the northern side of Tel Aviv at 1810
hours and proceeded directly to the Liberty. By 1835
hours, the Israeli Sikorsky helicopter, carrying Com-
mander Castle, was over the ship hovering at approx-
imately 30 feet from bridge level. Lettering on the
tail of the helicopter was SA32K and on the fuselage
were the numerals 06 or D6. The helicopter had
neither an electric megaphone nor hand-held signal
light with which to communicate with the Liberty.3o
(U) Wearing civilian clothes, Commander
Castle could not convey his identity to the bridge of
Liberty but by visual means indicated that he wished
to be lowered aboard the ship. At first, Commander
McGonagle prepared to receive the attache but, con-
sidering the obstructions in the forecastle area, sig-
naled a wave-off to the transfer attempt. Simultane-
ously, the helicopter pilot said he could not make the
transfer because of the Liberty's speed. A few minutes
later an impromptu package weighted with an orange
was dropped from the helicopter onto the forecastle.
Inside the package was a message written on a calling
card of "Commander Ernest Carl Castle, United
States Navy, Naval Attache for Air, Embassy of the
United States of America, Tel Aviv." On the back of
the card was written, "Have you casualties?" Using an
Aldis lamp, the Liberty attempted for ten to fifteen
minutes, to reply to this message with "affirmative
casualties." It was not clear to those on the ship that
the reply was understood. Castle, however, had re-
ceived the message but was uncertain as to whether
the number flashed was four or forty. The bodies of
three crew members had not yet been removed from
the forecastle and must have been observed by those
in the helicopter. With the waning light and approach
of dusk the helicopter departed the ship at approxi-
mately 1900 hours."
(U) Shortly thereafter, at 1915 hours, the
Liberty transmitted to CNO a post-attack situation
report. 32

communications of the attacking aircraft or torpedo
boats were available. However, one of the airborne
platforms operating from Athens, had collected voice
conversations between two Israeli helicopter pilots and
the control tower at Hazor Airfield (near Tel Aviv).
Control told helicopter 815 at 1431 hours that"there
is a warship there which we attacked. The men jumped
into the water from it. You will try to rescue them."
Although there were other references to a search for
the men in the water, no personnel from the Liberty
had jumped overboard. At 1434 hours, the control
tower told helicopter 815 that the ship was Egyptian
and that he could return home. At 1510 hours, the
controller asked 815 to identify the nationality of any
survivors. Subsequently, the helicopter pilot reported
seeing an American flag on the ship. In another portion
of the conversation, the pilot of helicopter 815 reported
that number GTR 5 was written on the ship's side
and that behind the ship were several uninflated life
boats. At 1521 hours the helicopters were instructed
to return home.
Liherty Licks Its Wounds (U)
(U) As darkness settled over the Liberty,
Commander McGonagle remained on the bridge, still
suffering from the loss of blood and experiencing a
great deal of pain from his wounds. By remaining on
the bridge, McGonagle believed his presence there
would give reassurance to the crew. The Liberty's
doctor, Lieutenant Kiepfer, had seen McGonagle on
the bridge but made no effort to get him below to a
battle dressing station. In Lieutenant Kiepher's words,
The Commanding Officer at that time was like a rock upon
which the rest of the men supported themselves. To know that
he was on the bridge grievously wounded, yet having the conn
and helm and ... calling every change of course, was the thing
that told the men "we're going to live." When I went to the
bridge and saw this, I should say that I knew that I could only
insult this man by suggesting that he be taken below for
treatment of his wounds. I didn't even suggest it. 15
(U) The attack had demanded the very
best from the Liberty's crew and they had responded
exceptionally well. Damage control competence mini-
mized Liberty's structural wounds and kept her afloat.
The engineering crew under Lieutenant George Golden
maintained power to the engines so that the Liberty
could move away from dangerous shoals in the attack
area and head toward the Sixth Fleet. The medical
officer and his two corpsmen needed help and they got
it. In Kiepfer's words,
Any time we needed one volunteer, we'd get ten. If anything
had to be done ... there were hands everywhere. When we

asked for two pints of blood for transfusion, we had people on
the adjoining tables who were saying, "If you need some, I have
this type." These were people already wounded. 36
NSA civilian, Robert L. Wilson, remembered, too,
that surprisingly there was no panic. When the men
were ordered to do something, they did it. Everyone
was kept busy. Though some were obviously scared to
death, there was simply no panic; nobody ran rampant
through the ship. No one slept much that night.
Helping the wounded became everyone's job - even
those with no medical training. Men learned to dress
wounds or do stitches. In some cases to quiet a man,
he was given a bottle of rum to drown his pain. With
the lengthening hours of darkness, deepening depres-
sion and shock caused some men to break down and
succumb to the fears they had been able to restrain
during the attack and immediately thereafter. 37
(U) Alone, battered, and scarred but un-
vanquished, the Liberty steamed steadily on through-
out the night toward a rendezvous with Sixth Fleet
destroyers. Three musters were taken to identify the
dead, the seriously injured, and those who were
missing. Casualty messages were completed as quickly
as possible and necessary message notifications sent.

Chapter V
The Israeli Explanation (U)
The classification of paragraphs in this chapter which derive
from the statement of the Israeli Defence Forces Court of Inquiry
results from a government of Israel request to the Department of
State that the information "be treated on a restricted and confi-
dential basis."
fSt- The Israeli Defence Forces Court of
Inquiry into the U.S.S. Liberty incident presented its
findings to the Military Advocate General who rec-
ommended that a preliminary judicial inquiry be held
to determine if there was any individual or individuals
against whom any charges should be brought. The
examining judge was Lieutenant Colonel Yishaya
Yerushalmi. He gave his decision under date of 21
July 1967. From the report of that decision comes the
following Israeli account and explanation of the attack
on the Liberty'
Chronology of Israeli Actions (U)
~ At 0600 hours (local time) on 8 June
1967, an Israeli aircraft, with a naval observer on
board, located a ship 70 miles west of Tel Aviv. On
the basis of this information, Israeli Navy Headquar-
ters marked the object in red (meaning an unidentified
target) on the combat information center plot table.
~ At about 0900 hours, another Israeli
plane reported sighting a ship 20 miles north of AI
'Arish, The pilot reported that the ship was "coloured
gray, very bulky, and the bridge amidships." The ship
was then identified by the Israelis as a supply vessel
of the American Navy; thereupon, the marking on the
combat information center plot table was changed to
green (a neutral ship).
11- Later that morning at 1055 hours, the
Naval Liaison Officer at Israeli Air Force Headquarters
reported to the Acting Chief of Naval Operations at
Navy Headquarters that the ship sighted earlier was
"an electromagnetic audio-surveillance ship of the
U.S. Navy, named Liberty, whose marking was G. T.R.-
5." Upon receiving this data, the Acting Chief of
Naval Operations ordered the target erased from the
combat information center plot table because he had
no current information as to its location. Thus from
this moment on (approximately 1100 hours) the Lib-
erty no longer appeared on the combat information
center plot table at Israeli Navy Headquarters.
-ft Between 1100 and 1200 hours, Navy
Headquarters received reports that Al 'Arish (occupied
by Israeli ground troops) was being shelled from the
sea. These reports came from two separate sources,
the Air-Ground-Support Officer and the Israeli South-
ern Command. At 1205 hours, the Head of the Naval
Department ordered three torpedo boats of the division
at Ashdod to proceed toward Al 'Arish to locate the
target. Air Force Headquarters was advised of this
navy action and it was agreed that, when the torpedo
boats located the target, aircraft would be dispatched.
Accordingly, the commander of the torpedo boat
division was ordered to establish radio contact with
the aircraft as soon as they appeared over the target.
(U) The torpedo boats located an uniden-
tified target at 1341 hours 20 miles north of AI 'Arish
and reported that it was moving toward Port Said at
a speed of 30 knots. A few minutes later, the torpedo
boat division commander reported that the target,
then 17 miles from him, was moving at 28 knots, and
since he could not overtake it, he requested the
dispatch of aircraft towards it. This was done; the
aircraft executed a run over the ship (Liberty) in an
attempt to identify it but saw no flag or other
identification mark. They did, however, report to
headquarters that the ship was painted gray and two
guns were situated in the bow. On the assumption
that the ship was an enemy target, Air Force Head-
quarters gave the aircraft an order to attack.
~ During the first stage of the attack
the aircraft strafed the ship with cannon and machine
guns and during the second stage dropped bombs on
it which caused fires and smoke aboard the ship. As
(U) Israeli motor torpedo boat of the class which attacked the Liberty:.

(Figure is UNCLASSIFIED)
the torpedo boats drew near, the aircraft were ordered
to leave the target. During the last run, a low-flying
aircraft reported to headquarters that it saw the
marking "CPR-5" on the ship's hull.
~ Upon receipt of this information about
the ship's marking, the Naval Operations Branch, at
approximately 1420 hours, ordered the torpedo boat
division commander not to attack inasmuch as the
aircraft may have possibly identified the target incor-
rectly. The division commander was ordered to ap-
proach the ship in order to establish visual contact
and to identify it. He reported that the ship appeared
to be a merchant or supply vessel and that when he
signalled the ship and requested its identification the
ship replied with a signal meaning "identify yourself
first." At the same time, the division commander was
consulting a book on the identification of Arab Navies
and making comparisons with the target before him.
He concluded that the target was an Egyptian supply
ship named El-Kasir, Simultaneously, the commander
of another of the torpedo boats informed the division
commander that he, too, thought the ship was the EI-
Kasir. Therefore, at 1436 hours, the division com-
mander authorized the torpedo attack to begin. Only
after a torpedo struck the ship and one of the torpedo
boats approached it from the other side were the
markings" CTR-5" noticed on the hull. Then the order
was given to cease the attack.
38 eONPIDHNTIAL
it Throughout the contact, no Israeli
plane or torpedo boat saw an American or any other
flag on the ship. It was only an Israeli helicopter, sent
after the attack to render assistance - if necessary
- that noticed a small American flag flying over the
ship. At this time, the vessel was finally identified "as
an audio-surveillance ship of the U.S. Navy."
Israeli Prosecutor's Charges of
Negligence (D)
it" Based on the foregoing account, the
Israeli Chief Military Prosecutor submitted a number
of charges of negligence to the examining judge of the
Preliminary Inquiry. The examining judge was then to
decide whether or not there was sufficient prima facie
evidence to justify bringing the accused to trial for
fflT Given below are the charges brought
by the Chief Military Prosecutor together with the
judge's findings.
tt 1. Charge: The first charge related to
the failure of the Acting Chief of Naval Operations to
report to the Head of the Naval Department that the
American ship, Liberty, was seen in the morning hours
of the day of the incident sailing in the vicinity of the
Israeli coast.
Finding: Though the Head of the
Naval Department testified that he did not know of
the Liberty's presence in the area on the day of the
incident, the Officer of the Watch at Navy Headquar-
ters testified that the Head of the Naval Department
was on the Navy Command Bridge when the Com-
manding Officer of the Navy ordered the marking (on
the combat information center plot table) of the
American supply ship changed to green (indicating a
neutral vessel). Since the Acting Chief of Naval
Operations was an eyewitness to the event, he con-
cluded that the Head of the Naval Department did
know about the presence of an American supply ship
in the area. In view of this, the examining judge found
no negligence on the part of the accused.
~ 2. Charge: That the Acting Chief of
Naval Operations failed to report to the Head of the
Naval Department that the hull markings on the ship
. observed by one of the attacking aircraft were similar
to those on the Liberty.
Finding: Witnesses testified that
when the Naval Liaison Officer at the Air Force
Headquarters telephoned the Naval Command Bridge
about the hull markings and their similarity to those
of the Liberty, the officer to whom he spoke repeated
the message in a loud voice so that it was heard by all
present on the Command Bridge including the Head
of the Naval Department. The examining judge stated,
therefore, that there was thus no reason to repeat to
the Head of the Naval Department a fact that had
been audibly announced to those present. The charge
was dismissed.
1'67- 3. Charge: That the Naval Liaison
Officer at the Air Force Headquarters was negligent
by not reporting to the Air Force the information
about the presence of the Liberty in the area.
Finding: The examining judge con-
sidered this charge unfounded. The responsibility for
the defense of Israel against enemy naval actions rests
solely with the Navy. Even though Air Force Head-
quarters ordered the aircraft to attack, it was really
an order issued by the Navy, passed on through Air
Force Headquarters. The Naval Liaison Officer at the
Air Force Headquarters was entitled to assume that
the decision to attack was made after considering this
report about the Liberty. There was no reason to feed
the Air Force with information and considerations
that did not concern it.
~ 4. Charge: That the Naval Depart-
ment's order not to attack the ship (the Liberty), "for
fear of error and out of uncertainty with regard to the
true identity of the ship," was not delivered to the
torpedo boat division.
Finding: Though the torpedo boat
division commander claimed he never received the
message not to attack, the deputy commander of the
boat testified that he had received the message and
passed it on to the division commander. The examining
judge believed that, in the heat of battle, it was
possible that the message escaped the awareness of
the division commander and, in any event, there was
insufficient evidence to commit any accused person to
~ 5. Charge: That it was negligence to
give the order to attack a warship without previously
establishing, beyond doubt, its national identity and
without taking into account the presence of the Amer-
ican ship, Liberty, in the vicinity of the coast of
Finding: To the examining judge,
there was no doubt that the dominant factors in the
initial attack decision were the speed and course of
the target. Those in command were entitled to assume
that the reported speed (28 knots) of the ship was
correct, within the usual limits of reasonable error of
10-15 percent, relying upon the existing means of
determining the speed of the target. It was, therefore,
concluded that this was a military vessel, and since
the Liberty was classed as a cargo ship, there was no
reason for surmising, in view of the speed, that the
target could possibly be the ship, Liberty. If one adds
to this other factors such as the report of the shelling
of the Al 'Arish coast for hours on end, the ship's
course toward Port Said, the aircraft report that the
target was a warship and carried no naval or other
identification marks, and the ship's location close to
shore in a battle zone, the cumulative effect negates
any presumption whatsoever of a connection between
the American supply ship and the target discovered
by the torpedo boats. Thus, the examining judge
concluded that the assumption it was an enemy ship
was reasonable and that the order given to the aircraft
to attack was justified.
~ 6. Charge: That it was negligent to
order the torpedo boat to attack the ship upon an
unfounded presumption that it was an Egyptian war-
ship, and this as a consequence of not taking reason-
able steps to make proper identification.
Finding: The examining judge con-
sidered it noteworthy that the identification of the
target as the El- Kasir was made both by the division
commander and the commander of a second torpedo
boat. Upon examining photos of the two ships, he was
satisfied that a likeness existed between them, and
that an error of identification was possible, especially
when the identification was made while the ship was
eONFIDENCfIAL 39

clouded in smoke. The Chief Military Prosecutor
argued that this identification was unreasonable be-
cause it was inconceivable to think that this auxiliary
ship El- Kasir could shell the Al 'Arish coast or that
she could move at a speed of 28 knots. In reply, the
examining judge said that it seemed reasonable to him
that the El- Kasir might have been part of the vessels
that shelled the coast and failed to get away from the
area or that the ship had come to assist in the
evacuation of Egyptian soldiers struggling away from
areas occupied by Israeli forces. Further, the judge
said that there was no doubt that the Liberty's refusal
to identify herself to the torpedo boats contributed
largely to the error of identification.
(U) In summation, the judge concluded
that in all the circumstances of the case the conduct
of the naval officers concerned in the Liberty incident
could not be considered unreasonable to an extent
which would justify committal for trial.
Explanation Reexamined (U)
(U) Reexamination of Israel's explanation
of why its air and naval forces attacked the Liberty
reveals egregious errors in both command judgments
and operational procedures.
The incident is doubly tragic when it
is realized that three hours before the attack occurred,
Israeli Navy Headquarters was made aware of the
(U) U.S.S. Libert,y arriving in Malta after the attack.
(Figure is UNCLASSIFIED)
Liberty's presence, including exact name, ship type',
and hull number. The first error in responsible military
operations came when the Liberty's identity was totally
erased at 1100 hours from the combat information
center plot table at Naval Headquarters because no
exact location for her was known after 0900 hours on
8 June.
ter The next sin of omission was the
Israeli Navy's failure to share with the Air Force full
details about the Liberty's presence off the Al Arish
coast. This combat parochialism was almost certainly
a factor contributing to the attack on the Liberty -
the examining judge's opinion to the contrary. Even
the Israeli examining judge alluded to such possibility
when he said:
Indeed, whoever peruses the ample evidence presented to me,
may conceivably draw some lesson regarding the relations
between the two arms of the Israel Defence Forces, which
were involved in the incident, and the operational procedures
in time of war....
~ In spite of the fact that the Israeli Atr
Force did not have all the information about the
Liberty that was available to the Navy, the pilots of
the attacking planes were at fault for failing to make
positive identification of the Liberty before attacking
the ship. Though the pilots testified to the contrary,
every official interview of numerous Liberty crewmen
gave consistent evidence that indeed the Liberty was
flying an American flag - and, further, the weather
conditions were ideal to assure its easy observance and
identification. These circumstances - prior identifi-
cation of the Liberty and easy visibility of the Amer-
ican flag - prompted the Department of State to
inform the Israeli Government that
the later military attack by Israeli aircraft on the U. S. S.
Liberty is quite literally incomprehensible. AB a minimum,
the attack must be condemned as an act of military reck-
lessness reflecting wanton disregard for human life.
~ In the chain of mistakes, the next one
occurred when the division commander of the attacking
torpedo boats failed to hear his deputy tell him that
Naval Headquarters had ordered the boats not to
attack for fear of having mistaken the ship's identity.
The Israeli examining judge exonerated the com-
mander because he believed it quite possible that the
message "escaped the awareness of the division com-
mander in the heat of battle."
tet The final error was the identification
of the Liberty as the Egyptian supply ship El- Kasir,
The fact that two separate torpedo boat commanders
made the same false identification only raises the
question of the veracity of both commanders. The El-
Kasir was approximately one-quarter of the Liberty's
tonnage, about one-half its length, and offered a
radically different silhouette. To claim that the Liberty
closely resembled the El-Kasir was most illogical.
(U) The Department of State expressed
its view of the torpedo attack in these words:
The subsequent attack by Israeli torpedo boats, substantially
after the vessel was or should have been identified by Israeli
military forces, manifests the same reckless disregard for
human life. The silhouette and conduct of V.S.S. Liberty
readily distinguished it from any vessel that could have been
considered hostile....It could and should have been scrutinized
visually at close range before torpedos were fired.... The
Vnited States Government expects the Government of Israel
also to take the disciplinary measures which international
law requires in the event of wrongful conduct by the military
personnel of a State... [and] to issue instructions necessary to
ensure that United States personnel and property will not
again be endangered by the wrongful actions of Israeli
military personnel. J

decision of the Israeli Defence Forces Preliminary
Inquiry, he summed up his personal feelings on the
subject by calling it "a nice whitewash.:"

Chapter VI
Recovery and Initial Assessment (U)
(V) Sixteen and one-half hours after the
Liberty was attacked, V.S. assistance finally reached
her. At 0625 hours (local time) on 8 June, the
destroyers V.S.S. Davis (DD-937) and V.S.S. Massey
(DD-778) rendezvoused with the ship at 33-0IN, 31-
59E, a position 420 miles east-southeast of Soudha
Bay, Crete. The carrier, V.S.S. America, was still 138
miles from the Liberty, closing at 30 knots.'
Medical Assistance (U)
(V) The Commander of Destroyer Squad-
ron Twelve, Captain H. G. Leahy, and other personnel
from the Davis and Massey immediately boarded the
Liberty to assist in controlling damage and in treating
the injured. Only after this transfer did Commander
McGonagle relinquish his watch on the bridge. He was
exhausted and in danger of having his wounds become
infected. Temporary command of the Liberty was
assumed by the Operations Officer of Destroyer Squad-
ron Twelve. Upon completion of a medical assessment,
the Commander, Sixth Fleet was advised that the
Liberty was ready to transfer 15 seriously wounded
and 9 dead to the America when its helicopters
arrived. The possibility of anyone being alive in the
flooded spaces was deemed unlikely. Bulkheads were
firm and the flooding contained, so that the Liberty
was completely mobile to 10 knots. The Davis assumed
all communications functions for the Liberty. Further,
Sixth Fleet was advised that, upon arrival of the fleet
ocean tug, V.S.S. Papago, the destroyer Massey could
return to fleet duties.
(V) While Liberty's on-board needs were
being tended to, two boats from the destroyers
searched the area around the Liberty for two hours
looking for classified papers that might be washing out
from the pear-shaped, gaping hole in the flooded
Research Department spaces; no classified items were
(V) At approximately 0915 hours, all ships
got under way and headed toward the carrier America
at 10 knots. By 1030 hours, two helicopters from the
America reached the Liberty and began evacuating
the seriously wounded back to the carrier. One hour
later, the America rendezvoused with the Liberty.
Thereafter, the group of ships set a course for Soudha
Bay, Crete, some 300 miles away.
Commander, Sixth Fleet Arrives (U)
(V) Later that afternoon, Vice Admiral
William 1. Martin, Commander, Sixth Fleet, boarded
the Liberty for one hour to visit its captain and crew
and to personally survey the damages sustained. Fol-
lowing his visit, Vice Admiral Martin recommended to
the Commander-in-Chief, V.S. Navy Europe, Admiral
John S. McCain, Jr., that the Liberty proceed direct
to Malta for dry docking rather than to Soudha Bay
first because of the primary necessity to protect the
cryptomaterial and equipment. Admiral McCain gave
his approval. 4
(V) Also visiting the Liberty during the
late afternoon of the 9th was Captain Russell Arthur,
Sixth Fleet Maintenance Officer, who reported to the
V. S. Commander-in-Chief, Europe the following cor-
rective actions: "established water-tight boundaries at
frames 52 and 78 and at second-deck level and made
repairs to gyro, engine-order telegraph, rudder-angle
indicator, fathometer, sound-powered phones and
bridge-steering control." The Liberty's crew was aug-
mented as necessary, and accompanied by the tug
Papago; and the destroyer, Davis, she proceeded
toward Malta at 10 knots.
Replacement Inquiries (U)
(6 660) A possible replacement for the Liberty
was already being considered. At approximately 1300
hours, the Director, Naval Security Group Europe
sent a message t0L] u .uuu ItlIeAmeficaarid

also forwarded Lieutenant Bennett's request that a
team from the Naval Security Group Europe meet the
Liberty when she docked at Malta to assist in evalu-
ation of compromise of cryptomaterials and prepara-
tion of reports.
Recovery of Sensitive Materials (U)
CU) Mounting concern over the possible
loss of sensitive documents drifting out of the Liberty's
ruptured Research Department's operations space
prompted NAVEURtodirect Sixth Fleet on 9 June to
do whatever is feaeible to keep any Soviet ships out of Liberty's
wake.... maintain observation of Liberty's wake and if possible
find-out what sort of documents are being lost in the wake.... take
whatever steps may be reasonable and appropriate to reduce
possibility of compromise, noting that a compromise could have
both political and technical aspects.'
(U) Liberty's escorts reacted quickly and
most effectively to minimize the uncontrollable loss of
sensitive materials. Though a Soviet guided-missile
destroyer (DDG 626/4) of the Kildin class remained
in the vicinity of the Liberty between 1320 and 1600
hours on the 9th, she was kept under constant sur-
veillance and did not stop or recover anything. The
Davis, Massey, or Papago trailed in Liberty's wake-
constantly to recover papers adrift. The first night,

the night of 8-9 June, the Chief and Deputy Chief,
NSA Civilian Personnel (Messrs. William M. Holleran
and Albert W. Ulino) drove to the Silver Spring home
of Allen Blue's wife, Patsy, to notify her that Allen
was missing in action.'?
(C CCO) On 10 June, the Director, NSA sent
a message to NSA Europe directing that a represent-
ative be sent to meet the Liberty at Malta to provide
maximum assistance and guidance in respect to NSA
personnel, local liaison, and informational reporting to
NSA. The Director. NSA directed NSA Europe to
arrange for Robert L. Wilson's transportation home
by quickest means and to relay messages for his wife.
All appropriate assistance was to be given to Donald
L. Blalock in arranging for his return to the U. S.
Information copies of the message were sent to Senior
U. S. Liaison Officer, London and to the Director,
Naval Security Group Europe. 13
Assistance to NSA P e r ~ o n n e l (C CeO)
(U) As the Liberty steamed westward on
10 June, Commander McGonagle had the shrapnel
removed from his leg and was resting comfortably.
With adequate provisions of food, fuel, and water on
board ship to reach Malta, there was concern about
crew morale and Sixth Fleet was requested to have a
helicopter pick up the Liberty's outgoing mail as soon

the Papago picked up one classified item ten miles
behind Libert-y,'
(0 CCO) Enroute to Malta, the Papago contin-
ued to take exceptional measures to recover materials.
Always in Liberty's wake, she used boat hooks and
crab nets to pick up floating material. Lights were
rigged on Papago's bridge wing so that visibility at
night was even better than during the day. When
material could not be recovered, Papago ran over it
with her propeller and then backed down over it to
shred the paper into small pieces. Although some
paper with typing on it did not disintegrate in nine
hours when placed in water by Papago'e CO, it was
believed that ocean-wave action would have caused the
fanfold paper (which was in multimessage blank
lengths) to ball up and sink or at least not be easily
visible. Total materials recovered by the Papago
weighed eight pounds; highest classification was secret

(U) In Washington. after the general de-
tails of the attack on the Liberty had been absorbed,
there was. quite naturally, a clamor for specific
information about casualties - their names and
extent of injuries. The Liberty forwarded the best
information obtainable, but data about those missing
was elusive. During the Israeli attack and immediately
thereafter. the Liberty conducted no search for per-
sonnel because none had been reported overboard and
she was trying to clear the area as soon as possible.
On 10 June. the U.S. Commander-in-Chief, Europe
notified JCS that the Liberty's flooded compartment
could not be opened to account for missing personnel
until the ship was drydocked. To do otherwise would
risk further flooding and peril the ship and the lives
of the survivors who were taking the crippled vessel to

After Rear Admiral Renken left Nor-
for his TG 100.3 (Public Affairs) was
as possible and at the same time deliver mail addressed
to the ship's company. 14 The Liberty continued clean-
up operations aboard ship as well as the grisly task of
accounting for personnel that were missing. On 11
June, the Papago recovered one body floating six miles
astern of the Liberty; another person previously re-
ported missing was now confirmed dead after recovery
aboard ship. 15
Command Investigations Initiated (U)
(U) While the Liberty limped steadily to-
ward Malta under the watchful protection of the Davis
and Papago, U.S. military commands in the Pentagon
and in Europe were feverishly arranging for the
drydocking of the ship plus full-scale investigations of
the events and circumstances surrounding the attack
itself. The Joint Chiefs of Staff appointed a fact-
finding team on 9 June and initiated plans for the
team to visit, in turn, the Commander-in-Chief, U. S.
Navy Europe; U. S. Commander-in-Chief, Europe;
Commander, Sixth Fleet; and the U.S.S. Liberty,"
(U) On the 10th, after conferring with the
Commander-in-Chief, U.S. Navy Europe, the U.S.
Commander-in-Chief, Europe recommended to JCS
that a Navy Court of Inquiry be established. In his
message to JCS, CINCEUR gave his rationale for this
action as follows:
Have reviewed available data with respect to Liberty with
CINCUSNAVEUR in general frame of chronology before acci-
dental attack, during attack and subsequent thereto. We both
have many very pertinent and as yet unanswered questions as
we appreciate Washington has. At the same time, [it] must be
recognized [that] crew members of Liberty from whom answers
must be gotten are at point of exhaustion, suffering from
wounds and shock, dead or missing. It simply does not make
sense, legally or otherwise, to initiate barrage of uncorrelated
questioning via long-haul communications at this time. Ob-
viously facts must be developed involving actions and judgments
of crew, Liberty command and chain of command, and also
legal base must be established for possible claims against
government of Israel. Therefore, I strongly endorse establish-
ment of Court of Inquiry by Commander-in-Chief, U.S. Navy
Europe, as proper procedure... although it may be somewhat
time-consuming and create impatience among those who desire
more rapid answers.
JCS gave immediate concurrence and on 11 June, the
Commander-in-Chief, U.S. Navy Europe convened the
court in London with directions to proceed promptly
to the Mediterranean and board the Liberty at sea as
soon as possible. 17
(U) In Israel, too, high-level investigations
were being considered. On 13 June, the Israeli Defence
Force Chief of Staff, General Rabin, appointed an
official Court of Inquiry to examine the Liberty
incident. 18
(U) To provide for the handling of the
Liberty when she arrived at Malta, Admiral McCain,
activated Task Force (TF) 100, effective 12 June,
under the command of Rear Admiral Henry A. Ren-
ken, Commander, Service Force Atlantic Fleet sta-
tioned in Norfolk, Virginia. CTF 100 was charged
1. Supervising the drydocking, removal, and ship-
ment of remains of personnel killed in action;
2. Preventing disclosure of classified information
and material to unauthorized personnel; and
3. Readying the Liberty for repair by Com-
mander, Service Force Sixth Fleet.
These functions were expected to be completed within
two days after Liberty's expected arrival in Malta on
13 June. Subordinate task group commanders were
instructed to be prepared to report in person to Rear
Admiral Renken at the U. S. Embassy in Malta by
noon, 12 June.
(U) Of the eight subordinate task groups
that comprised Task Force 100, the Director, Naval
Security Group Europe was directed to provide person-
nel for TG 10004, (Security); this group was to assume
responsibility for all materials requiring special han-
dling, including their removal from the Liberty, trans-
fer to secure storage, and continuous security at all
times. 20
(G GGO) Captain Carl M. Smith, Director, Na-
val Security Group Atlantic, was designated Com-
mander, TG 100.4; other TG 100.4 personnel were
Commander E. H. Platzek; Lieutenant Commander
Benjamin M. Bishop; Lieutenant Philip G. Firestone,
USNR; Lieutenant R. H. Lee; Lieutenant M. H.
Bennett (from the Sigint component aboard the Lib-
erty); and CTC Alfred J. Pawlinkowski. Additionally,
NSA Europe named Lieutenant Colonel Robert T.
Green, USAF and Clarence R. Klumfoot (NSA security
officer) to assist TG 100.4 as necessary. II Of this
group, Bishop, Firestone, and Pawlinkowski were fur-
ther designated to assist Lieutenant Bennett, as he
had requested, with the evaluation of security com-
promise and preparation of required reports. 22

with its services, the Director Naval Securit Grou
Europe also arranged

compiled and radioed for delivery to him as he passed
through Rota, Spain, enroute to Malta. TG 100.3's
mission was to satisfy the legitimate interests of
newsmen without compromise of classified information,
unwarranted interference with operations, or invasion
of individual rights of privacy. Further, it was directed
that all public affairs activities be conducted with the
aim of maintaining the credibility of the official
announcements regarding the mission of U. S. S. Lib-
erty; i.e., she was a communications research ship
that was diverted from her research assignment to
provide improved communication-relay links with the
several U. S. embassies around the entire Mediterra-
nean during the current troubles. 24
(U) Specific ground rules were set forth
for press coverage of Liberty's arrival in Malta.
Newsmen were not to be permitted in the immediate
vicinity of the dockyard while the Liberty entered the
dock, unless CTF 100 was satisfied that the torpedo
hole was adequately covered; while the drydock was
pumped out, regardless of covering; and after the dock
was pumped out, until all remains were removed and
classified matter safeguarded. If newsmen asked about
these restrictions, they were to be told that the actions
were being taken primarily out of consideration of
families of missing personnel, since remains may be in
the exposed compartment and visible to photogra-
phers; and because communications spaces normally
contain classified equipment and are closed to the
public, since it must be assumed that some classified
equipment is exposed. Additionally, no interviews of
the officers or crew of the Liberty were to be granted
until authorized by Commander-in-Chief, U.S. Navy
Europe, after completion of the Court of Inquiry. If
queried by the press about the reason for such policy,
the security officer (TG 100.4) was to say that these
men are potential witnesses before the Court of Inquiry
and it is the desire of the convening authority and the
President of the Court that recollections of witnesses
remain as fresh as possible and not be influenced in
any way by outside discussions. The doctrine of
security at the source was to be followed at all times
and there was to be no censorship of newsmen's
material. 25
(U) Upon arriving at Malta, Rear Admiral
Renken met with his task group commanders and
American embassy officials on Tuesday, 13 June, to
complete plans for docking operations, which would
commence on Liberty's arrival - then estimated at
about 2300 hours that night.
Blalock Returns Home (U)
(e eeO) That same afternoon, NSA civilian,
Donald L. Blalock (earlier evacuated from the Liberty
to the U. S. S. America with minor shrapnel wounds)
was released from America's medical department and
flown to Athens. There he was met by NSA Europe
representative, Charles Cowardin, who arranged for
Blalock's travel to the United States. Blalock arrived
at Washington National Airport the following day. 27
Liberty's Arrival at Malta (U)
(0 000) Liberty's arrival in Malta was delayed
until 0630 hours, 14 June. Precautionary safety meas-
ures had required additional shoring of damaged
bulkheads and her speed was reduced. Divers from the
Papago immediately began an underwater inspection
of the ship's hull to determine whether or not changes
in the keel blocks would be necessary before drydocking
could begin. The keel was found to be straight and
undamaged. At 1400 hours the Liberty entered the
drydock; by 1530 hours a canvas net had been tied
across the damaged side of the ship and screens had

been installed across all drydock drains. During the
pump down, navy swimmers and men in a rubber raft
picked up oil-covered paper as it floated out of the
ship. When the drydock was completely drained, a
thorough search of the entire drydock and each drain
screen was conducted by indoctrinated Naval Security
Group personnel. NSA Europe personnel, sent to
Malta, witnessed all drainage operations. 28
Evacuation of Wilson (D)
(C 000) Earlier, as soon as the Liberty entered
Malta, NSA Europe personnel boarded the ship to see
NSA civilian Robert L. Wilson. When Wilson said he
did not wish to stay aboard any longer, he was quickly
ushered to the U.S. Consulate in Valletta for a short
debriefing. Immediately thereafter, accompanied by
Lieutenant Colonel Green (from the NSA Europe
staff), he returned home. Later Wilson learned that
his wife had been continually informed by NSA per-
sonnel of what was going on from the time the whole
incident began; they had even offered to have someone
stay with her.
Clearing Damaged Areas (D)
(U) In Malta the search for and removal
of bodies began at 1830 hours on the 14th and
continued until approximately midnight, by which
time the remains of 20 men, including Allen Blue, had
been recovered. Bodies of the remaining five missing
men were presumed lost at sea enroute to Malta.
Liberty's death toll stood at 34.

Research Department space, a guard was posted and
all personnel were required to log in when authorized
access. Crews of indoctrinated personnel began remov-
ing all classified equipment and documents to a secure
space one deck above the damaged area. This recovery
process proved to be very slow because the classified
equipment and material was mixed with the mass of
twisted wreckage. Of course, no repair to the ship's
side could begin until the damaged area was freed of
all classified papers and equipment. By 19 June, all
classified matter (including 168 large canvas bags) had
been stowed under guard in a secure space aboard the

June, newsmen and photographers were given a rigidly
controlled tour of Liberty's topside area plus several
compartments on the lower decks, near the point of
impact, from which all classified equipment had been
removed. Later that afternoon, Task Force 100 was
officially dissolved. Some task force personnel remained
with the Liberty, however, to help wind up adminis-
trative, public affairs, and supply matters. The Sixth
Fleet Maintenance Officer also remained to supervise
Libert y' s repairs."
Damage Survey at Malta (U)
eC CC6) In Washington, the Naval Ships En-
gineering Center was coordinating a visit to the Liberty
to survey damage in order to expedite repairs to the
ship's electronic system; it was recommended that the
inspection team include contractor personnel plus NSA
and NSG people. 32 Thus, Eugene Sheck, Comint
Collection (Mobile) Management, K12, and Lieuten-
ant Allan Deprey, VSN, Sigint Engineering (Mobile
and Space), K32, in company with representatives of
the Naval Security Group, Naval Ships Engineering
Center, and contractor respresentatives of Ling-Temco-
Vought (LTV) and the FTM Systems Company visited
the Liberty on 19-21 June. Their findings confirmed
the massive damage to the Sigint electronic
eo CC6) With the exception of the TRSSCOM
system antenna, all antennas were either destroyed,
damaged, or burned to some degree; almost complete
replacement of the antenna system would be required.
In Research Room no. 1, equipment not completely
destroyed by the torpedo explosion had been totally
submerged in heavy oil and salt water for six days,
rendering it beyond salvage. The processing and re-
porting spaces, transcribing positions, maintenance
shop and cryptographic room were severely damaged;
all equipment was either destroyed by the explosion or
removed from the spaces at Malta because of extensive
damage. In the Research Department and non-morse
search and development areas on the second deck,
very little outward damage was noticeable. However,
the shifting of the racks and breaks in the air
conditioning ducts indicated considerable shock dam-
age; each and every piece of gear would require
complete checks. Additionally, internal wiring and
patching facilities between all research spaces would
have to be checked. From the initial inspection, it was
obvious that considerable replacement of internal
wiring would be required. Preliminary, informal esti-
mates made by the engineers inspecting the Liberty
indicated that the cost to reconfigure the platform
would range between four and six million dollars. 33
JCS Fact Finding Team's
Interviews (U)
(V) While the Liberty was being cleansed
and surveyed in the Malta shipyard, the Navy and
JCS investigative bodies were busily interviewing ap-
propriate personnel aboard the Liberty and at various
European command headquarters.
(G GGO) Headed by Major General Joseph R.
Russ, VSA, the JCS Fact Finding Team arrived in
London on Tuesday morning, 13 June and spent most
of the day at Commander-in-Chief, V.S. Navy Europe
Headquarters interviewing Admiral John S. McCain,
Jr., and members of his staff. Late that afternoon,
the team flew to Stuttgart to talk with V.S. European
Command personnel involved in the Liberty incident.
The following day's interviews also included one with
Brigadier General William Keller, Chief, NSA Europe.
Points covered in the talk with Keller were:
1. Explanation of the mechanics involved for
tasking in satisfaction of both national and theater
consumer intelligence requirements;
2. Technical reports issued by the Liberty (the
JCS Team was provided a copy of Liberty's reports
from 2 through 8 June); and
3. Adequacy of Criticomm service to EVCOM in
handling of the Mid-East crisis. No unusual delays
were experienced and pertinent Sigint product was
received by J-2 EVCOM on a timely basis.
Both the JCS team and J-3 EVCOM appeared satis-
fied with General Keller's explanations. 34
(V) On 15 June, the team spent two hours
visiting Vice Admiral William 1. Martin, Commander-
in-Chief, Sixth Fleet, and staff aboard his flagship,
the U. S. S. Little Rock. The team arrived in Malta at
1815 hours on the 15th and departed for London at

Russ and his team visited the Liberty and also spoke
with Rear Admiral I. C. Kidd, President of the Naval
Court of Inquiry. The JCS team returned to Washing-
ton in the early evening of 18 June.
Accounting for Classified Material (U)
(C CCO) Though activities aboard the Liberty
immediately upon arrival at Malta had centered on
readying the ship for repair, the requirement to
account for all on-board classified material had not
been overlooked. Not only had many classified docu-
ments been lost, but the records and inventories of
sensitive materials and registered publications carried
aboard ship had also been destroyed. To reconstruct
Liberty's list of holdings, the Director, NSA requested
appropriate field station and NSA elements to compile
detailed lists of all technical support materials that
had been forwarded to the Liberty.35
(U) In Malta, Liberty personnel attempted
to make an inventory of registered publications but
found it to be fragmentary at best. The registered
publications vault and cryptospaces were completely
destroyed by the torpedo attack. In spite of the fact
that, just before the attack, most registered publica-
tions had been put in weighted canvas bags, it was
discovered that these bags were torn apart by the
blast of the torpedo explosion; no bags remained
intact. Further, those publications that were recovered
were unusable: they were either soaked in oil and salt
water or damaged by the blast. None could be page
checked for completeness. All paper and metal residue
from the damaged area were placed in canvas bags
and secured in locked spaces aboard ship under twenty-
four-hour guard. 36

(U) After Liberty personnel had completed
this action, Captain Carl M. Smith (who had been
TG 100.4 commander) informed the Director, Naval
Security Group that
despite [the] fact that all classified material cannot be accurately
accounted for and loss at scene [is] unknown, [am] confident that
possibility of compromise is reasonably unlikely while Liberty
[was] en route [to] Malta and zero thereafter. It was a time-
consuming task under difficult conditions but thoroughness of all
has resulted in maintenance of highest degree of security integrity.
All can take justifiable pride in dedication, willingness, and high
morale of those participating in the salvage operation. 37
Joint Survey at Norfolk (U)
(U) Recognizing that the Liberty had had
extensive reserve, on-board cryptographic keying ma-
terials that might require replacement Navy-wide and
DoD-wide, the Chief of Naval Operations proposed
that a joint survey team meet the Liberty when she
returned to Norfolk and take a sampling of the residue
to determine whether a sorting operation was possible,
and to make recommendations for further actions or
disposition of material. The survey team membership
would be drawn from the Naval Security Group, Naval
Intelligence Center, and NSA.
(e CeO) NSA representatives to this team
were: Billy Durham, Operations, Comsec Status,
(S13); Benjamin G. Cwalina, Security, Research Divi-
sion, (M55); and Lieutenant John T. McTighe, USN,
Operations Staff, (G04). On 31 July, these three
traveled to Norfolk, Virginia, and hoarded the Liberty,
just returned from Malta. There they were joined by
other members of the survey team, principally NSG
personnel. Following a brief tour of the ship, the team
was taken below decks to the Research Operations
spaces, where the canvas bags of residue were piled.
Sailors from the Liberty's Sigint complement, dressed
in rubber overalls and gloves, selected about six or
seven bags at random from the grimy, oily 160-plus
total and, one by one, opened each and dumped its
KANDt! ViA e6I\HN'f eUANNHtS 6NM' CONFIDENTIAL 55
contents on the floor in front of the survey team. It
was not a pretty sight and had malodorous qualities
resulting from the combination of oil, brackish sea
water, burned metal, paper, and pieces of human
flesh. The team immediately agreed that it would be
impossible to make a page-by-page check of the bags'
contents. From looking at this sampling, the survey
team concluded that:
1. Eighty percent of the material was unidenti-
2. Some of the material was definitely discernible,
readable, and classified; and
3. Some of the classified material was identifia-
ble, in part, by short titles and cover markings or
name-plate designations; e.g.; large bound volumes or
The team recommended that:
1. No attempt be made to conduct a detailed bag-
by-bag search for the sole purpose of identifying
classified material;
2. The Commanding Officer of the Liberty be
authorized to destroy the bagged material held on
board; and
3. Prior to the process of burning, an effort be
made to empty each bag at the incinerator to deter-
mine the possible existence of identifiable registered
publications and that each such complete publication
be accounted for prior to its destruction. 39
(U) CNO concurred with the survey team's
recommendations and authorized destruction as re-
quested. At the Director, NSA's request, all remaining
Comsec material (excluding that in canvas bags)
aboard the Liberty at the time of attack was segre-
gated and forwarded to NSA for inspection;"
(0 000' With this command approval, Lib-
erty's CO arranged for appropriately cleared personnel
to fill a trailer with bagged residue and burn it at the
Norfolk incinerator. A list of documents identified in
the burning process was forwarded to CNO. At NSA,
M55 determined that there was only minimal security
damage and no compromise had occurred.
(0 000) Though incinerator flames consumed
the last bits and pieces of oil-soaked residue from the
assault on the Liberty these ashes did not mark the
end of the train of events set in motion on 8 June
1967. The Israeli attack had already taken the lives
of 34 Americans - 25 from the Siginit unit, including
Allen Blue, and 9 of the Liberty's crew - and touched
those of scores more. The investigations then under
way would affect even more people.

Chapter VII
The Incident under Review (U)
(U) Following the attack on the Liberty,
both the Executive and the Legislative Branches set
about ascertaining the basic facts surrounding the
incident. Other than the U.S. Navy Court of Inquiry
and the cursory Israeli Board of Inquiry immediately
after the event, reviews went forward under the
auspices of the House Appropriations Committee, the
JCS, and NSA. In addition, a Special Committee of
the National Security Council elicited information to
answer the Administration's questions on the incident.
The NSA Review and Reaction (U)
(U) The eighth of June proved to be a
busy day for NSA's directorate. Having received a
Critic message on the Liberty's dilemma, Brigadier
General John Morrison of NSA's Production Organi-
zation, notified the directorate of the event at about
0900 hours, Washington time. Some 45 minutes later,
the directorate learned that the attack had been by
the Israelis.
(6 660) Immediate concern was for the safety
of the personnel and the security of the materials on
board. During the day urgent requests went out from
NSA to the National Military Command Center
(NMCC), other offices in the Pentagon, and the
Bureau of Naval Personnel to ascertain if the names
of any of the three NSA civilians on board appeared
on the casualty list. Both General Marshall S. Carter
and Dr. Louis W. Tordella became aware that the
ship was in shallow water, 35-40 fathoms. And they
knew, of course, that the ship held technical materials
which would reveal the mission of the ship and that
it had electronic equipment which would compromise
U. S. success in demultiplexing VHF and UHF multi-
channel communications. Accordingly, Dr. Tordella
asked JRC's Captain Merriwell W. Vineyard, USN, to
have all documents on board the Liberty burned and
all equipment saved, if possible. General Carter was
prepared to recommend all necessary action to insure
the security of the technical material and equipment,
should the ship go under but, in discussions with the
JRC, ruled out the deliberate scuttling of the ship
since its presence in shallow water made compromise
of materials and equipment a distinct possibility.
(0 000) Other concerns were for the reassign-
ment of the Liberty's intercept mission to other
collectors,1 lin the
face of the inevitable attention the press would. give
to this incident, and for developing a core of infor-
mation for the expected questions the Agency would
receive from DoD and other officials.
(8-000) As the eighth of June wore on, the
NSA staff considered wa s to reassi Liberty's mis-

redeployment of the U.S.S. Belmont, scheduled for
refitting at Norfolk at about that-time. Only the last

Tordella discussed this matter with Rear Admiral
Ralph E. Cook. the Director Naval Securitv Group.
I This stated that the
Liberty's presence off Port Said was "to assure com-
munications for the U. S. Government posts in the
Middle East and to assist in relaying information
concerning the evacuation of U.S. dependents and
other citizens from the Arab-Israeli war area." As was
its custom, NSA's staff worked closely with the Pen-
tagon's Public Information Office and referred all
public queries NSA received to that Pentagon Office.
(0 000) There was, finally, on that long day of
8 June, the need to establish quickly a core of
information on the incident to prepare for the many
questions being asked and decisions to be made.
Already the Secretary of Defense, Robert S. Mc-
Namara, had called General Carter asking for "precise
information" on the ship's complement, the number
of civilians, the meaning of "AGTR" which appeared
on the ship's hull, and other matters which he felt
would be needed for a public release. Discussions also
took place with White House staff members Patrick
Coyne and Bromley Smith, who elicited details on the
(0 000) To take care of this need for infor-
mation, General Carter established in his outer office
a Temporary Mid-East Information Group consisting
Mr. Walter Deeley of the
Production Organization andl land Lieu-
tenant Commander Edward Koczak, USN, of the
Director's staff. The main function of this group was
to gather information on the event and to anticipate
the numerous questions to be directed to NSA over
the coming weeks.
(8 000) With timely help from agency compo-
nents, the group assembled basic data on the ship
itself, on U.S. I Icoverage of Middle East
communications; on operational and technical respon-
sibilities, and on the technical rationale for the
mission; it also compiled /a chronology of events and a
compendium of key documents and messages. Assem-
bling the information in a large red notebook entitled
"Report to the DirectorNSA - U.S.S. Liberty (AGTR-
5), 23 May-8 June 1967," the group presented the
completed report to the Director on 12 June - rather
respectable staff work in view of the timeliness and
EO 1.4. (c)
quality-of" the report. NSA was then in a position to
give copies of this comprehensive report to the JCS
Fact Finding Team and to the Special Committee of
the National Security Council (NSC).
(0 660) Directed as it was to develop a core of
information on the event, the NSA group did not seek
to identify remedies for faulty procedures or, for that
matter, to make any recommendations at all. Major
responsibility for that fell to the JCS and others. The
group did have to field searching questions being asked
the Agency by others.
(6 660) The JCS Fact Finding Team was ask-
ing specific questions such as these:
Does NSA receive and plot situation reports? Does
it keep the track?
Why was an Opscomm circuit not established
between NSA and the Liberty?
Were there any communications problems during
transit in the Mediterranean?
Did NSA fail to receive any technical summaries,
product, or other communications from the Liberty,
nonreceipt of which would have been indicative of
communications difficulties?
Was there any departure from normal command
relationships in the handling of the Liberty's cruise?
(0 600) And Patrick Coyne of the National
Security Council's Special Committee asked broad
questions such as these:
What information was received from the Liberty
from the time it arrived on station until the incident?
Were there any Sigint reflections of the Israeli
Would we receive all of our Sigint holdings relating
to the incident?
(U) Although questions remained which
would require answers, the work of the NSA group was
essentially complete by the middle of June 1967. I
The JeS Review (U)
(U) On 9 June, immediately after the
Liberty incident the JCS fielded a five-man team from
its organization, all with the necessary clearances, to
examine communications and control aspects of the
event. Senior member of the JCS team was Major
General Joseph R. Russ, USA. Other team members
were Rear Admiral Francis J. Fitzpatrick, USN;
Colonel William A. Garrett, USAF; Captain William
D. Owen, USN; and Major Harlan E. Priddle, USAF.
(U) In spelling out the terms of reference
for the team, Lieutenant General B. E. Spivy, Director
of the Joint Staff, asked the team to examine the
EO 1.4. (c)
1.4. (d)
IIA:NBI.B fA: eOMIN'I' eIIANNBI.S ONI.
means employed in issuing operational directives of
the JCS to the V.S.S. Liberty and the specific orders
to the Liberty between 1 June and 8 June 1967, and
to identify and develop information on conflicting
directives, delays in message traffic, and nonreceipt of
orders. The team was to report its findings, along with
recommendations, to the JCS.
(0-006) The JCS team visited NSA, other
Washington-area principals, and concerned military
staffs and commands in Europe and the Mediterra-
nean. On 10 June, as the team began its fact-finding
mission, General Carter called General Russ and
offered the total cooperation of NSA and followed
through on this offer by making as much information
available to him as required, although General Russ
had already decided not to concentrate on sensitive
(that is, special intelligence) matters.
(V) As the work of the fact-finding team
was drawing to a close, General Russ provided on 18
June a preliminary report to the Chairman of the
Joint Chiefs of Staff, General Earle Wheeler, VSA.
He apprised the Chairman of the four messages from
higher headquarters on 7/8 June to subordinate com-
mands designed to change the Liberty's CPA, receipt
of which by Liberty "would undoubtedly have resulted
in the ship's being a greater distance from the scene
of action.... " Despite the Liberty's having been either
an action or an information addressee on each of these
messages, General Russ's team found no evidence that
the ship received anyone of them. Nor did his team
find, for that matter, any evidence of conflicting
directives governing the Liberty's operation. General
Russ also made note of the irregular procedure JCS
itself had adopted in bypassing Commander-in-Chief,
Europe when it passed verbal instructions to Com-
mander-in-Chief, V.S. Navy Europe, and he recounted
the reasons for delays at NAVEUR and Sixth Fleet in
translating the JCS directive into action.
(V) By 20 June the JCS Fact Finding
Team had completed its work, had prepared its report,
and had made its recommendations to the JCS. Of
the 17 recommendations made, 9 concerned the mis-
sions, functions, operational responsibilities, and op-
erational control/technical tasking and guidance mat-
ters; the other 8 related to communications, traffic
management, methods, facilities, and availability of
trained personnel. In reviewing and commenting on
the report's recommendations for the JCS, the J3 and
J6/JCS reserved follow-on action for the first category
of recommendations to the Joint Staff but assigned
responsibilities to various other agencies for study and
implementation actions in the second category of
recommendations. NSA drew assignments on three
recommendations dealing with emphasis on dedicated
command-and-control circuitry rather than on
common-user circuitry, with measures to improve fleet
control communications via communications satellite
technology, and with the amalgamation of NATO and
V.S. military communications.
(0 OOQ) Other than the three recommendations
on which it participated as an action agency, NSA
was concerned about some of the other findings in the
report. One recommendation was, for example, that
"procedures governing the control of surveillance plat-
forms be made more definitive with respect to tech-
nical research ships to insure that "artificial barriers
between operational elements of staffs and NSNNaval
Security Group" owing to security considerations be
eliminated "in order to improve the value and timely
utilization of the Sigint products at all major command
echelons." Insofar as NSA was concerned, this rec-
ommendation was off the mark since Sigint product
already went directly to all commands and not through
NSNNaval Security Group staffs. NSA commented
formally on this point in a letter to Major General
G.B. Pickett, Vice Director for Operations (J-3); in
its commentary on the Russ report for the JCS, the
J-3 discounted this recommendation.
(V) When copies of the JCS Fact Finding
Team's report reached NSA at the end of June,
General Carter instructed the chief of his telecom-
munications organization, Colonel Leslie J. Bolstridge,
VSAF, to review the report in minute detail with a
view to "correcting our procedures wherever we can
profit from this debacle of military communications."
Since the Russ report primarily dealt with command-
and-control communications, the Russ recommenda-
tions had only marginal pertinence to NSA's own
Congressional Review (U)
(V) Following a hearing focusing on the
JCS messages which failed to reach the Liberty, the
House Appropriations Committee on 14 August 1967
directed its Surveys and Investigations staff to examine
the effectiveness of the DoD worldwide communications
system. The staff studied the delays and nondelivery
of messages originated on 7 and 8 June directing the
withdrawal of the Liberty as a springboard to its
broader review of DoD's worldwide communications.
The staff produced a two-volume report for the chair-
man of the congressional committee. Volume I re-
viewed the communications problems in the Liberty
incident, volume II the worldwide communications
systems and networks of the DoD.

gations staff interviewed JCS, NSA, Naval Commu-
nications Command, Department of Army Communi-
cations Center, and JCS Message Center personnel in
the Washington area and most of the military com-
mands and communications centers in the Pacific and
European regions which had been involved with Lib-
erty's communications in one way or another.
(U) Essentially the staff covered the same
ground that General Russ's team plowed earlier. They
worked their way through all the communications
errors made during the attempts to withdraw the
Liberty on 7/8 June. The staff was somewhat more
critical than the JCS Fact Finding Team of the failure
to deliver to the Liberty the information copies of the
JCS and CINCEUR messages directing withdrawal
(JCS 080110Z June 67 and CINCEUR 080625Z June
67). Specifically, they wanted to know if a typical
commander would take action on an information copy
of this kind from a higher command before receiving
the implementing message of his immediate superior.
They tested the matter with unnamed U. S. Navy
officials who had commanded both large and small
naval vessels and learned, according to the report,
that there would have been no question that if the
Liberty had received the information copies, "the
Captain of the Liberty would have moved within
minutes without waiting for an implementing order."
(U) In its volume II, the congressional
staff took full note of the breakdown of the precedence
system in communications and drew upon 000-
provided information for the Middle East crisis. Of
some 452 high-precedence, (Flash and Immediate)
crisis-related 000 messages, only 22 percent of the
Flash and 30 percent of the Immediate messages
actually met established precedence criteria.
(U) Part of the' delay in transmitting the
Immediate-precedence Sixth Fleet withdrawal message
to the Liberty, it will be recalled, was owing to the
urgency of equal or higher precedence (that is, Flash)
messages. During the crisis, originators assigned Im-
mediate precedence to messages on subjects such as
these: enlisted men reassignments, hospital-patient
reports unrelated to the crisis, friendly ship locations
and movements, setting up of press conferences,
changes in reporting formats, U. S. military sales
policies, and reorganization of Army Reserve units. In
contrast, actual instructions called for assignment of
Immediate precedence to "situations which gravely
affect the security of national/allied forces or populace,
and which require immediate delivery to the addres-
sees" - for example, amplifying reports of initial
enemy contact, reports of unusual major movements
of military forces of foreign powers during peacetime
or during strained relations, attack orders, and urgent
intelligence messages.
(U) While the congressional staff directed
most of its attention to 000 command communica-
tions, it also took note of Criticomm which, they found
functioned throughout the crisis relatively free of
problems. The staff was aware of steps NSA took to
keep Criticomm free of the overburdening traffic
common in crisis situations, particularly an 8 June
action in which NSA directed the curtailment of
electrical forwarding of all routine reports so that
crisis-related traffic could flow expeditiously.

Chapter VIII
A Final Look (U)
(0 000) Perhaps the Liberty has undergone
scrutiny long enough. First the Israeli Court of Inquiry
examined the event, exculpation of Israeli nationals
apparently not being hindmost in the court's calcula-
tions. Then the U. S. Navy Court of Inquiry studied
the incident. The JCS review actively sought to
identify faulty procedures and practices for corrective
action. The NSA review was essentially fact-finding in
nature. And the House Appropriations Committee
review, made as it was without all the information
available to the JCS team, nonetheless reconstructed
many of the basic findings of that team and sought to
use them as a mirror in which to observe problem
areas in DoD's worldwide communications. Despite the
official scrutiny, it is still necessary to comment briefly
on a few subjects of interest and concern to cryptologic
Safety Estimates for Collection Missions
of Mobile Platforms (U)
t7 One principal area of concern was the
manner in which safety factors were adjudged. Prior
to the Liberty incident, commanders did not essen-
tially regard mobile collectors as integral components
of their commands. After all, JCS/JRC assigned the
schedules and routes, the platforms existed to satisfy
"national intelligence" and - as they may have
thought - not their own intelligence requirements,
and NSA was on the sidelines as a major interested
party. As General Russ learned, commanders accord-
ingly felt some uncertainty as to their specific respon-
sibilities in supporting these platforms. The General
reasoned therefrom, and so stated in his report, that
commanders must have adequate knowledge of a ship's
mission if they are to control and support it effectively.
(U) JCS/JRC looked to the unified and
specified commands to provide for the safety of the
mobile collectors. The regional commands were in close
touch with political and military conditions in which
the platforms operated and were, JCS/JRC believed,
in the best position to evaluate safety factors. I
(C CCQ) ,. In the Liberty incident, the Com-
mander, Sixth Fleet, was responsible for the safety of
the ship. But Vice Admiral Martin was not in a
position to evaluate the expected intelligence gain or
assign degrees of importance to the expected intelli-
gence gain in terms of changing risk factors. Judgment
on the value of the intelligence to be gained could
come only from DoD-level intelligence agencies - and,
in the case of the Liberty, particularly from NSA.
(0 000) In the aftermath of the incident, there
was indeed some soul searching on this point within
NSA. The head of NSA's Temporary Mid-East Infor-
mation Group told Dr. Tordella in mid-June that he
believed NSA could not really absolve itself totally
from the safety considerations. He believed that NSA
may have to demonstrate "that the need is not
established frivolously" and questioned whether or not
the intelligence requirements against which NSA
worked at the time were really of such a compelling
nature as to justify using the special operational areas
in the Middle East which NSA designated.
(0 000) One has to pose this question. Had
NSA sent a message to the JCS/JRC on 5 June, the
day war broke out, and stated simply that the agency
which initiated the mission in the first place, NSA,
now believed the risk to its cryptologic materials and
personnel outweighed its estimate of technical and
intelligence benefits to be derived, would there have
been more expeditious action by JCS/JRC to cut the
mission short? NSA may have drawn a mild rebuke
for presuming to evaluate safety factors. But the
hypothetical NSA message might have added to the
position the CNO was taking at about this time to
increase the ship's CPA, and it might have stimulated
JCS/JRC action earlier than 080110Z.
(0 000) On 8 June NSA was, however, of a
totally different mind. Since it did not want to lose
IIANBbH ".tIA COflfHN'f CIIANNHbS ONbl' eONFIDHN'fIAL 61
'fOP SECRE'f
the coverage it had planned for the Middle East, it
sent a message to the JCS/JRC proposing assignment
of the U.S.S. Belmont to the eastern Atlantic/Medi-
terranean as soon as possible after that ship's expected
arrival at Norfolk on the next day." The Director,
NSA later withdrew this request in the face of
reluctance on the part of the Commander-in-Chief,
Atlantic" and reevaluation of the CPA constraints on
mission effectiveness.
(6 660) In reflecting on the Liberty/ Pueblo
incidents in an oral history interview, General Mar-
shall S. Carter said
as a result of both of those traumatic experiences, we have
reviewed our procedures and found there was little change
needed in NSA-JCS relationships, but there were some changes
needed in the chain of command supervision and monitoring...
of just where the ship is, and what it is doing, 'and was it
(6 660) As it turned out, the Liberty incident
- and some six months later the Pueblo seizure -
brought about some modification in the JCS/JRC
procedures for weighing risk vs. intelligence-gain fac-
tors. Instead of relying entirely on military assess-
ments, the new procedures took into account
intelligence-agency information relating to potential
Just prior to the Pueblo's capture, NSA had
apprised the JCS of Sigint from North Korean com-
munications portending difficulties for the Pueblo.
(U) NSA should not yield or should yield
grudgingly to others, this review would suggest, in
safety evaluations of missions involving large holdings
of Sigint materials, equipment, and personnel.
Availability of Linguists (U)(C-CCOI-
(6 660) Looking back on the Liberty incident,
one perhaps should fault the cryptologic organization
for not assuring the presence on board of qualified
Hebrew linguists for on-station examination of Israeli
voice communications uncovered in the intercept from
the nonmorse search and development mission and for
not even having a token mission on Israeli voice
communications. It turned out that Hebrew language
tapes produced by USN-855 from the search and
development mission on the morning of 8 June did not
contain information on the forthcoming Israeli attack,
but NSA did not learn this until it had received these
tapes and had processed them several days after the
event. For all NSA and USN-855 knew at the time,
information on Israeli intentions towards the ship
might well have been on those tapes.
(6 660) Hebrew linguists were, to be sure, in
short supply. In sending three Hebrew linguists to fill
out the staff of the U. S. Air Force Security Service's
EO 1. 4 . (c I
technical processing center at I INSA had sent
to the field all but one of its Hebrew linguists. Prior
to the Liberty's arrival at Rota, Spain, the Naval
Security Group had inventoried its available linguists
in order to select Arab linguists for assignment to
USN-855. One of the selectees, it turned out, carried
the classification "Special Arabic" - in reality,
Hebrew- and assignment of that individual was by
accident rather than by design. USN-855 did not use
him as a Hebrew linguist.
(U) As in other situations - the lack of
Vietnamese linguists during the Vietnam period, for
example - this lack of Hebrew linguists showed that
the linguist talent pool available to U. S. cryptologic
agencies for employment in crisis conditions was not
always adequate.
Communications Problems (D)
(U) Errors made in the handling of com-
munications accounted, in some measure, for the
Liberty tragedy. Studied in great detail by the JCS
Fact Finding Team and reviewed by the staff of the
House Appropriations Committee, the communications
problems posed a challenge for the JCS and for DoD
agencies in the immediate post-Liberty period.
(U) NSA was not the DoD action office for
correcting faulty communications procedures, but it
was indeed a very interested party to corrective actions
stimulated by the Russ Report. Doing what he could,
General Carter called Army Chief of Staff, General
Harold K Johnson, about the considerable number of
mishandled messages in the Department of Army's
communications center in the Pentagon, particularly
those coming to NSA, and on 3 July provided General
Johnson's staff with examples of message mishandling
during the Liberty incident. Department of Army's
response was positive, and soon thereafter its Com-
munications Staff added page monitors on its circuits
to NSA to check assignment of address groups. Errors
diminished from some 40 to 7 a day out of an average
daily total of 1,000 transmissions. General Carter also
insisted, as noted earlier, that his staff examine the
Russ Report recommendations relating to DoD com-
munications for any possible application to NSA's
Criticomm network.
File Reduction for Exposed Collectors (U)
('f'S 660 nF) The Six Day War and the Liberty
incident created conditions in which Sigint personnel
had to take fast action to prevent loss of their
documentation and e ui ment.

the problem, did encounter difficulties because of the
time required to destroy records and neutralize equip-
ment. In its report on emergency destruction of Sigint
documentation and equipment I I
recommended reduction to the absolute minimum of
detachment files as one measure to facilitate the
destruction. The report stated:
Technical documents, operational aids, etc., should be limited
to those required to carry out the mission; files held and
containing information that mayor may not be needed at some
future date should be eliminated. The library of training
manuals ought to be limited to those covering items of equip-
ment in use at the detachment; anyone who cannot read a
TEXTA card can be taught without the use of a TEXTA
Manual; a Traffic Analyst's Handbook is not needed where
there are no traffic analysts, nor is a cryptographic textbook
where there is no cryPtanalysis,:.a;:c.::;;co;;.:m:;Jp;;.:l,::is.::h.::;;ed:;,._' ...,
The cryptologic holdin s of
were small in comparison with those held by the
('T'S-CCO) After the Liberty incident, a review of
USN-855's cryptologic documentary holdings showed
that the Sigint unit held technical reports such-as
TEXTA, Techins (Technical Lnstructione), tasking
records of all kinds, Informal Technical Notes, and
Comint Technical Rep():rtsf6rl IMiddle
Eastern, I Icountries, and the U.S.S.R. -
documents which would have made possible, granted
a serious compromise, a country-by-country index to
the Sigint success achieved by the U. S. for the
countries concerned. The Sigint unit also held collec-
tion management records recapitulating intercept as-
signments by case notation at U.S. Sigintsites world-
wide. In addition, USN-855 held much/of the Musso
(Manual of U.S. Sigint Operations) library spelling
out Sigint policy and procedures. It held numerous
records denotingI // I
IAndjt heldthen current S.. igint product for
JMiddleEastern countries, and the
(S OCO) USN-855 had received this comprehen-
sive documentation primarily from NSA's collection
management, telecommunications, and G Group of-
fices, Naval Security Group Headquarters, and U.S.
in microcosm.
(G GGO) Asked if the ship had too much Sigint
documentation and equipment, one USN-855 survivor
Entirely too much. There is no way emergency destruction
could be carried out unless you were given... two day's notice
that you're going to get hit. And usually you're not given any
notice. 10
(G GGO) Casual examination of document list-
ings reveals, of course, countless records which were
not specific to USN-855's eastern Mediterranean mis-
sion, records which could have remained behind at
Rota. This same judgment would probably not apply,
on the other hand, to on-board Sigint equipment,
virtually all of which was essential to the mission.
ft- The Liberty's experience, together with
the Pueblo capture, led to some emphasis on file
reduction and on measures to facilitate destruction of
cryptologic materials and equipment. The incidents
pointed up, as no others had done before.the need for
scaling the distribution of technical documentation to
specific and minimal levels necessary for execution of
tasks, and following the incidents some moderationin

Unanswered Questions (U)
(U) A persistent question relating to the
Liberty incident is whether or not the Israeli forces
which attacked the ship knew that it was American.
Several authors and not a few of the Liberty's crewmen
and USN-855 staff are convinced that they did. Their
belief derived from consideration of the long time the
Israelis had the ship under surveillance prior to the

attack, the visibility of the flag, and the intensity of
the attack itself.
(O-CCO) Speculation as to Israeli motivation
varied. Some believed that Israel expected that the
complete destruction of the ship and killing of the
personnel would lead the U.S. to blame the U.A.R.
for the incident and bring the U.S. into the war on
the side of Israel. Ironically, even though the Liberty
had no specific mission against Israeli communications,
others felt Israeli forces wanted the ship and men out
of the way in order to deny the U.S. any Sigint on
Israel's preparations to attack. Syria - an attack the
U. S. might try to prevent.
(8 COO) Authors of .the several books now in
print about the Liberty.' whether members. of the
Liberty's complement or/ not, have not had access to
I Ii Sigint reports on the Israeli
helicopter pilot voice communications, nor have they
had access to the confidential Israeli Government's
explanation given to the U. S. Department of State.
(O-OeO) In part because of the press speculation
at the time, President Johnson directed the Director
of Central Intelligence, Richard Helms, to prepare a
report by 13 June, five days after the attack, assessing
the Israeli intentions. The CIA assessment drew heav-
ily upon the Sigint reports referred to above. While
these reports revealed some confusion on the part of
the pilots concerning the nationality of the ship, they
tended to rule out any thesis that the Israeli Navy
and Air Force deliberately attacked a ship they knew
to be American.
Denouement (U)
(U) On 11 June 1968, exactly one year
and three days after the attack on the Liberty, her
commanding officer, Captain William Loren Me-
Gonagle (promoted after the attack), was presented
the Congressional Medal of Honor by the Secretary of
the Navy for gallantry and courage displayed during
Liberty's hours of trial. Following that award, the
Presidential Unit Citation was conferred upon the
Liberty and crew on 14 June 1968 at Portsmouth,
(0 GGO) Scores of individual decorations
(Bronze Star, Silver Star., etc.) were given to crew
members, and 170 Purple Hearts were earned by
Liberty's complement, including two NSA civilians,
Donald L. Blalock and Allen M. Blue (the latter,
(U) Claims against the government of Is-
rael for compensation concerning deaths and injuries
of U.S. personnel and damage to the Liberty were
initiated by the Department of State. In May 1968,
Israel paid the U.S. Government $3,323,500 as full
payment on behalf of the families of the 34 men killed
in the attack. 13 Eleven months later, Israel paid
$3,566,457 in compensation to the men who had been
wounded. 14 The U. S. claim of $7,644,146 for material
damage to the Liberty itself was not settled until 18
December 1980 when Israel agreed to pay $6 million.
(U) After returning to Norfolk in July
1967, the Liberty languished there while NSA tried
unsuccessfully to obtain DoD budgetary approval to
restore her to Sigint operational status; the proposed
budget figure was $10,200,000. When this effort failed,
the Liberty was decommissioned on 28 June 1968. In
1970 the ship was turned over to the Maritime
Administration and sold for scrap for $101,666.66. In
1973 the ship came to an ignominious end as she was
cut up in Baltimore's Curtis Bay shipyard.
(U) There was one aspect of the Liberty
tragedy which should not go unnoted. This was its
adverse and lingering affect on the Liberty's survivors.
Oral interviews with USN-855 personnel some 13 years
after the event, show that time has not healed all the
scars." Apart from bitterness toward the Israeli Gov-
ernment, there still remains dismay that the U. S.
Government or Sixth Fleet did not come to Liberty's
aid in timely fashion.
(U) The contributions of technical re-
search ships to this nation's Sigint production also
should not go unnoted. These were unique in their
time, often irreplaceable, often unheralded. That the
TRS program came to an end in 1969 was not for lack
of competence and dedication of the men who served
or for lack of NSA's appreciation for their contribu-
tions, but rather for budgetary considerations by the
Department of Defense.
