During World War II, prisoners of war were required by the Geneva Conventions to be treated according to established rules. But in late 1944, when a large number of Americans were captured or surrendered during the Battle of the Bulge and elsewhere, their captors had different plans. Those who were Jewish or from some other “undesirable” ethnic or religious group were separated from their fellow captives and sent to the brutal slave-labour camp at Berga. Until now, the story of what these men endured has been a well-guarded secret.
