About half a million African Americans served overseas during World War II, almost all in segregated second-line units. This artificially limited their potential contribution, but their work - especially along the logistic lifelines of the fighting divisions - was vital. This book summarizes the service of these men and women; and it also focuses on the small proportion who, remarkably, overcame prejudicial barriers to reach the battlefields in combat units of the US forces and Coast Guard. Their story is illustrated with wartime photographs, and color plates - including portraits of the most outstanding African Americans, the true heirs of the old "Buffalo Soldiers."
