A prisoner-of-war camp in Japan during World War II was set up to provide skilled workers at a factory complex. But survivors say that the Japanese instead got motivated saboteurs of their war effort. The POWs got about half the 4,000 calories a day the U.S. Army considered the minimum but more than other POWs, said Gregory J.W. Urwin, a Temple history professor. "The Japanese didn't keep you healthy for fun," he said. At Mukden, they wanted work — and to look good for the Red Cross, which occasionally visited.
