The 1917 Riot was a mutiny by 150 black soldiers from the Third Battalion of the Twenty-Fourth United States Infantry. It lasted one afternoon, and resulted in the deaths of four soldiers and 15 civilians. The rioters were tried at three courts-martial. Ninteen were executed, and 51 were given life sentences.
A September 17, 1923 TIME Magazine article noted that part of the NAACP’s “Message to the People of the United States” at its 14th annual convention read: “We ask that the American people demand the release of the 54 members of the 24th Infantry now incarcerated at Leavenworth Federal Penitentiary for their connection with the Houston, Texas [race] riots of 1917.”
The battalion of black soldiers was stationed in Houston to guard the construction of Camp Logan.
