After WW2, there were 2,000,000 German prisoners or absent or dead on the Eastern Front. The Soviets reported they just held 850,000. That was a surprise to the Germans.
As a matter of fact, NO nation treated the German POW according to the worldwide convention . The Soviets send them into forced work for a long time, which few survived.
Remorseless were the Danish who send POW on the shorelines to influence the mines to detonate. More than 75 % did not survive.
Conversely, because of the endeavors of Konrad Adenauer, German detainees began getting back home by 1954 and were received as legends. At the point when the trains arrived, the German detainees were welcomed with thronging, cheering group, nourishment, et cetera.
