The harsh anti-Indian policies of President Mirabeau B. Lamar and Mexican efforts to weaken the Republic of Texas stirred Indian hostilities, and hatred increased after the Council House Fight in San Antonio on March 19, 1840, where 12 Comanche chiefs were killed. After regrouping and making plans for revenge, 600 Comanches and Kiowas, including women and children, moved across central Texas in early August and raided Victoria and Linnville, a prosperous seaport 120 miles southeast. About 200 Texans met at Good's Crossing on Plum Creek under Major-General Felix Huston to stop them. Adorned with their plunder from Linnville, the war party stretched for miles across the prairie. The Battle of Plum Creek on August 12, 1840, began on Comanche Flats 5.5 miles southeast and proceeded to Kelley springs 2.5 miles southwest, with skirmishes as far as present San Marcos and Kyle. Mathew Caldwell, for whom Caldwell County was named, had been injured in the Council House fight but took part in this battle, and volunteers under Edward Burleson included 13 Tonkawa Indians marked as Texan allies by white armbands. Texan casualties were light while the Indians lost over 80 chiefs and warriors, and the battle ended the Comanche penetration of settled portions of Texas.
