On September 3, 1918, five soldiers were hanged for alleged participation in the Houston riot (or Camp Logan riot). In all, 19 mutineers were executed. An excerpt from the article:
"On the hot, sunny afternoon of August 23, 1917, two white policemen broke up a craps game in the San Felipe section of Houston and then, while in pursuit of the suspects, broke into the house of a local woman, Sara Travers, whom they dragged outside in her torn nightgown. One passing soldier, Private Alonzo Edwards, was bold enough to approach the officer who was holding Travers with an offer to take custody of the distraught woman, possibly intending to return her to her home and de-escalate the situation – but instead Edwards was pistol-whipped for his presumption for speaking to a white police officer. Later that afternoon the same white officer clubbed another black soldier, Corporal Charles Baltimore, who asked after Travers; anger among the regiment’s Third Battalion, to which Baltimore belonged, reached a fever pitch with untrue rumors that he had been shot and died from the wound.
That night 156 black soldiers from the Third Battalion – apparently under the mistaken impression that a white lynch mob was about to attack the camp – armed themselves and marched from Camp Logan towards town, killing anyone they came across, for about two hours before the authorities surrounded and disarmed the mutineers. Altogether the mutineers killed nine white civilians and five white policemen, while four black soldiers were also killed by authorities – marking this as the only race riot in American history with more white than black fatalities.
Unsurprisingly, the official response to the Camp Logan riot and mutiny was draconian: around 100 members of the Third Battalion were tried collectively for murder in several court martials – making it one of the biggest murder cases in American history, measured by number of defendants – and 95 were convicted (top, a photo of the trial proceedings). Of these, 28 mutineers received death sentences and dozens of others were imprisoned.
The U.S. Army executed 13 soldiers almost immediately, all by hanging, and another six soldiers were hung at Camp Travis, Texas in September 1918. But the evidence for the involvement of many convicted soldiers in the mutiny and murders was often sketchy, based in many cases on contradictory eyewitness testimony, and protests from the National Association for the Advancement of Colored People (NAACP) and other civic groups prompted Woodrow Wilson commute ten of the remaining death sentences. The last mutineer was finally released from prison in 1938."
