We talk about Camp Hale, the Colorado Army base that was home to the 10th Mountain Division during World War II, but also home to 400 German POWs and the 620th Engineer General Service Company, a misfit unit of Nazi sympathizers. One of those soldiers would go AWOL with 2 German POWs in one of the biggest treason cases of the war.
