During the war, the armies of Western Allied nations such as Australia, Canada, the UK and the US were given orders to treat Axis prisoners strictly in accordance with the Geneva Convention. Some breaches of the Convention took place, however. According to Stephen E. Ambrose, of the roughly 1,000 US combat veterans that he had interviewed, only one admitted to shooting a prisoner, saying that he "felt remorse, but would do it again". However, one-third told him they had seen US troops kill German prisoners.
