question: Was either the Tet Offensive or Western Allied invasion of Germany started on a holiday?
answer: yes
context: Title: Matthew Ridgway
  Passage: General Matthew Bunker Ridgway (March 3, 1895 – July 26, 1993) was the 19 Chief of Staff of the United States Army.  He served with great distinction during World War II, where he was the Commanding General (CG) of the 82nd Airborne Division, leading it in action in Sicily, Italy and Normandy, before taking command of the newly formed XVIII Airborne Corps in August 1944, holding this post until the end of the war, commanding it in the Battle of the Bulge, Operation Varsity and the Western Allied invasion of Germany.
  Title: Tet Offensive
  Passage: The Tet Offensive (Vietnamese: "Sự kiện Tết Mậu Thân 1968" , or "Tổng tiến công và nổi dậy Tết Mậu Thân") was one of the largest military campaigns of the Vietnam War, launched on January 30, 1968, by forces of the Viet Cong and North Vietnamese People's Army of Vietnam against the forces of the South Vietnamese Army of the Republic of Vietnam, the United States Armed Forces, and their allies.  It was a campaign of surprise attacks against military and civilian command and control centers throughout South Vietnam.  The name of the offensive comes from the Tết holiday, the Vietnamese New Year, when the first major attacks took place.
  Title: 1969 in the Vietnam War
  Passage: Tet 1969 refers to the attacks mounted by principally North Vietnamese forces in February 1969 in South Vietnam during the Vietnam War, one year after the original Tet Offensive.

  Title: Vietnamization
  Passage: Vietnamization of the war was a policy of the Richard Nixon administration to end U.S. involvement in the Vietnam War through a program to "expand, equip, and train South Vietnam's forces and assign to them an ever-increasing combat role, at the same time steadily reducing the number of U.S. combat troops."  Brought on by the Viet Cong's Tet Offensive, the policy referred to U.S. combat troops specifically in the ground combat role, but did not reject combat by the U.S. Air Force, as well as the support to South Vietnam, consistent with the policies of U.S. foreign military assistance organizations.  U.S. citizens' mistrust of their government that had begun after the offensive worsened with the release of news about U.S. soldiers massacring civilians at My Lai (1968), the invasion of Cambodia (1970), and the leaking of the Pentagon Papers (1971).
  Title: May Offensive
  Passage: During the early morning hours of 1 May, communist units initiated PHASE II of the Tet Offensive of 1968 (also known as the May Offensive, "Little Tet", and "Mini-Tet") by striking 119 targets throughout South Vietnam, including Saigon.  This time, however, allied intelligence was better prepared, removing the element of surprise.  Most of the communist forces were intercepted by allied screening elements before they reached their targets.  13 NLF battalions, however, managed to slip through the cordon and once again plunged Saigon into chaos.  Severe fighting occurred at Phú Lâm (where it took two days to root out the 267th NLF Local Force Battalion), around the Y-Bridge in Saigon, and at Tan Son Nhut Air Base.  By 12 May the offensive was over as NLF forces withdrew from the area leaving behind over 3,000 dead and 7,500 wounded.
  Title: Battle of Coral–Balmoral
  Passage: The Battle of Coral–Balmoral (12 May – 6 June 1968) was a series of actions fought during the Vietnam War between the 1st Australian Task Force (1 ATF) and the North Vietnamese 7th Division and Viet Cong Main Force units, 40 km north-east of Saigon.  Following the defeat of the communist Tet offensive in January and February, in late April two Australian infantry battalions—the 1st and 3rd Battalions of the Royal Australian Regiment (RAR)—with supporting arms, were again deployed from their base at Nui Dat in Phuoc Tuy Province to positions astride infiltration routes leading to Saigon to interdict renewed movement against the capital.  Part of the wider allied Operation Toan Thang I, it was launched in response to intelligence reports of another impending communist offensive, yet the Australians experienced little fighting during this period.  Meanwhile, the Viet Cong successfully penetrated the capital on 5 May, plunging Saigon into chaos during the May Offensive in an attempt to influence the upcoming Paris peace talks scheduled to begin on the 13th.  During three days of intense fighting the attacks were repelled by US and South Vietnamese forces, and although another attack was launched by the Viet Cong several days later, the offensive was again defeated with significant losses on both sides, causing extensive damage to Saigon and many civilian casualties.  By 12 May the fighting was over, and the North Vietnamese and Viet Cong were forced to withdraw having suffered heavy casualties.  US casualties were also heavy and it proved to be their most costly week of the war.
  Title: Western Allied invasion of Germany
  Passage: The Western Allied invasion of Germany was coordinated by the Western Allies during the final months of hostilities in the European theatre of World War II.  The Allied invasion of Germany started with the Western Allies crossing the Rhine River in March 1945 before fanning out and overrunning all of western Germany from the Baltic in the north to Austria in the south before the Germans surrendered on 8 May 1945.  This is known as the "Central Europe Campaign" in United States military histories.
  Title: Massacre at Huế
  Passage: The Huế Massacre (Vietnamese: "Thảm sát tại Huế Tết Mậu Thân" , or "Thảm sát Tết Mậu Thân ở Huế, "lit.  translation: "Tet Offensive Massacre in Huế") is the name given to the summary executions and mass killings perpetrated by the Viet Cong (VC) and People's Army of Vietnam (PAVN) during their capture, occupation and later withdrawal from the city of Huế during the Tet Offensive, considered one of the longest and bloodiest battles of the Vietnam War.
  Title: 21st Army Group
  Passage: The 21st Army Group was a World War II British headquarters formation, in command of two field armies and other supporting units, consisting primarily of the British Second Army and the First Canadian Army.  Established in London during July 1943, under the command of Supreme Headquarters Allied Expeditionary Force (SHAEF), it was assigned to Operation Overlord, the Western Allied invasion of Europe, and was an important Allied force in the European Theatre.  The 21st Army Group operated in Northern France, Luxembourg, Belgium, the Netherlands and Germany from June 1944 until the end of the war in Europe in May 1945, after which it was redesignated the British Army of the Rhine (BAOR).
