One aspect of the war I have been meaning to read about is one rarely mentioned: Japanese POWs held in Russia.
Some of them, Koreans conscripted to fight for the Japanese, were captured, fought for the Soviets, captured again, fought for the Germans and then were captured again by us in Normandy.
There is a highly fictionalized Korean movie called 'My Way' which, last time I watched it, was on Netflix.
Interesting...never much considered that.
