The Cowra breakout occurred on 5 August 1944, when 1,104 Japanese prisoners of war attempted to escape from a prisoner of war camp near Cowra, in New South Wales, Australia. It was the largest prison escape of World War II, as well as one of the bloodiest. During the escape and ensuing manhunt, 4 Australian soldiers and 231 Japanese soldiers were killed. The remaining escapees were re-captured and imprisoned.
