Operation Pastel

from Wikipedia, the free encyclopedia

The operation pastel was drawn up in late spring 1945 and was a diversionary plan of the Americans to cover the planned but not executed invasion of the Japanese main islands (→ Operation Downfall ) to end the Pacific War . He was mainly referring to the sub-operation Olympic with the landings on Kyushu . The planned operations were simulated landings near Shanghai in China (Operation Longtom) in early October 1945 and on Shikoku in early December.

A deception plan approved by the Combined Chiefs of Staff in June 1945, Operation Broadaxe , envisaged invasions on Taiwan in late summer and Hokkaidō in early autumn, landings in Indochina in autumn and attacks on Sumatra from India in late autumn . Furthermore, additional bases should be secured in winter after an advance into the Yellow Sea . This plan was passed on to the leadership in Washington, DC at almost the same time as Operation Pastel . The overlap resulted in a conference on both plans that took place on June 27, 1945. As a result, the Pastel Plan was revised and issued on July 9th as Directive 1410 of the Joint Chiefs of Staff .

After the downfall dates were postponed, the plan for Operation Pastel was revised and rescheduled. The new operational dates ( Pastel Two ) were now for the beginning of April 1946 for a fictional invasion of South Korea and for the beginning of April for the Shikoku landings. In addition, the planners included a landing on Hokkaidō for the beginning of June. The Shanghai landings had been removed from the plan when the plan was passed on July 30, 1945.
