Koreans and D-Day

[Abd_Yesua_alMasih]

So this is a rather random question to put on a theological forum but I know a lot of you have been in the military or have studied military history or something similar. I have been reading Stephen Ambrose's "D-Day" and at the very start it mentions how the Americans captured a group of Koreans at Normandy. Apparantly they had been conscripted by the Japanese, captured by the Russians, captured by the Germans at Stalingrad (I think it was Stalingrad) and then eventually forced into fighting for Hitler in France along with Indians, Africans and other prisoners from all over the world. I never realised how 'international' the German army was by 1944.

My question is does anyone else know anything about this? I am really interested in what happened to the Koreans who were captured on D-Day but I am also interested in any books or articles which deal with the 'foreigners' in Hitler's army in WWII.
