The US Armed Forces were segregated until President Harry Truman issued Executive Order 9981 on July 26, 1948 which desegregated all the military service branches. That segregation during World War II helped create the Riot of Bamber Bridge in Great Britain in 1943. When US forces were sent to Britain that year black soldiers were met with respect and often open arms by the local population. The village of Bamber Bridge, Lancashire, then home to U.S. Army Air Base 569 was one such place. The 1511th Quartermaster Truck Regiment, a logistics unit stationed at the base consisted primarily of black soldiers. The all white 234th US Military Police Unit was stationed on the north side of the village and the two units were known to have had several skirmishes over race relations.
