No ceremonies marked the fiftieth anniversary of the wartime riots in New York, Los Angeles, Beaumont, Detroit, and Mobile. American political culture, if not recent historical analysis, continues to associate “the Good War” with national unity rather than unrest. But race tension was palpable to contemporaries. For example, ten months prior to Pearl Harbor and six months before a deadly shoot-out between black soldiers and white military policemen occurred in Fayetteville, North Carolina, that town had already earned the nickname “Uncle Sam's Powder Keg.” Less than ten miles from the city lay Fort Bragg, the nation's largest army camp, and visitors sensed a “seething undercurrent” of race friction coursing through the camp and the city. Thousands of black artillery trainees visited the downtown area each week, drinking and milling about in the streets. Because very few establishments welcomed their business, there was little else for them to do. A cab driver, asked about the city's hostile mood, replied that “the trouble is not ‘Is there trouble,’ but ‘What kind of trouble is it going to be and when is it going to pop?’” Similar questions animate this research, which explores the relationship between the Second World War mobilization and War Department practices and policies, on the one hand, and racial confrontations and violence involving soldiers, on the other.
