The wartime migration did not happen calmly, and in 1943 it boiled over. White mobs and hate strikes struck Black workers in Detroit, Mobile and Beaumont, Harlem rose against police violence, and servicemen beat Mexican American youth in Los Angeles. Dozens died and hundreds were hurt, and the racial order decided who did the killing and who did the dying.
Sources differ on the Beaumont death toll and the Mobile toll is limited or disputed. Harlem's riot was a Black uprising against police violence aimed at property, not a white-initiated attack, and false rumors repeatedly escalated the violence.
