On April 18, 1942, Jimmy Doolittle led the first bombing raid against Japan. Two five-man crews didn't make it back. Landing on Japanese-occupied territory in China, two drowned and the rest were captured one by one, as thousands of Japanese soldiers, in a massive manhunt, swept southward from Shanghai, scorching the earth behind them and slaughtering a quarter of a million Chinese peasants. For the Americans, capture meant solitary imprisonment, starvation, torture, and for some, death. Only four came home.
