who started the battle of the coral sea
Battle of the Coral Sea On 4 May, from a position 100 nmi (120 mi; 190 km) south of Guadalcanal (11°10′S 158°49′E﻿ / ﻿11.167°S 158.817°E﻿ / -11.167; 158.817), a total of 60 aircraft from TF 17 launched three consecutive strikes against Shima's forces off Tulagi. Yorktown's aircraft surprised Shima's ships and sank the destroyer Kikuzuki (09°07′S 160°12′E﻿ / ﻿9.117°S 160.200°E﻿ / -9.117; 160.200) and three of the minesweepers, damaged four other ships, and destroyed four seaplanes which were supporting the landings. The U.S. lost one torpedo bomber and two fighters in the strikes, but all of the aircrew were eventually rescued. After recovering its aircraft late in the evening of 4 May, TF 17 retired towards the south. In spite of the damage suffered in the carrier strikes, the Japanese continued construction of the seaplane base and began flying reconnaissance missions from Tulagi by 6 May.[32]
