Operation Coronet

During World War II, there were two "Operations Coronet," one of which was executed and the other only planned:

1. The planning name used for the capture of Woodlark[?] and Kiriwina Islands[?], off the eastern tip of New Guinea, by U.S. forces on 30 June 1944. Executed under the name Operation Chronicle[?]. the landings were unopposed. The operation formed part of Operation Cartwheel[?].

2. The planned invasion of the Japanese home island of Honshu at the Tokyo Plain south of the capital. First scheduled for 1 December 1945 and later postponed to March, 1946. This would have been the largest amphibious operation of all time, with fifteen divisions (including the floating reserve) earmarked for the operation. This invasion would have followed Operation Olympic; both attacks were components of Operation Downfall. It was never executed.
