The Brownsville affair, or the Brownsville raid, was an incident of racial discrimination that occurred in 1906 in the southwestern United States due to resentment by white residents of Brownsville, Texas, of the Buffalo Soldiers, black soldiers in a segregated unit stationed at nearby Fort Brown. When a white bartender was killed and a white police officer wounded by gunshots one night, townspeople accused the members of the African-American 25th Infantry Regiment. Although their commanders said the soldiers had been in the barracks all night, evidence was allegedly planted against the men.
