Where did the first man captured by the United States as a POW work after the war was over and why?

during the war, Allied nations, such as the United States and Great Britain, were ordered to treat Axis prisoners strictly in accordance with the Geneva Convention (1929). some breaches of the Convention took place, however. according to Stephen E. Ambrose, of the roughly 1,000 U.S. combat veterans that he had interviewed, roughly 1/3 told him they had seen U.S. troops kill German prisoners.
