Thanks for the info. I think most of the survivors never made it home. The German 6th Army, under Field Marshal von Paulus lost all but about 6,000 who eventually made it back to Germany. But I think you probably know more about the Eastern Front than I.
Neither the Russians or the Germans were very concerned about the Geneva Convention when it came to the treatment of prisoners.
Stalin himself was a cold SOB. The Germans captured his son. Hitler himself offered a prisoner swap for the son; Stalin refused and the son died in one of the Reich's POW camps before war’s end.
