Not only the high level of casualties to be expected in the invasion, but also, all POWs would most probably would have been killed. See the link here:- https://www.forces-war-records.co.uk...nese-1939-1945

This is what is said in the introduction:- "After the war, it became clear that there existed a high command order – issued from the War Ministry in Tokyo – to kill all remaining POWs."
