March 19, 1840. A contingent of Comanches came to San Antonio’s Council House for a peace conference with Texian authorities. But things went wrong.
The Texians expected the Indians to bring a number of captives with them (they had only one). They attempted to take the Comanches into custody but the Indians attempted to fight their way out. In the battle, 12 Comanche leaders were shot to death in the house, and another 23 died in the streets outside. Thirty Indians were captured. The Council House Fight led to decades of bloody warfare.
