The battle of Plum Creek was an aftermath of the Council House Fight, in which many of the Comanche Indian chiefs, their women, and warriors were killed. In the summer of 1840 the Comanches swept down the Guadalupe valley, killing settlers, stealing horses, plundering, and burning settlements. After sacking Linnville in Calhoun County, they started a retreat. The Texans organized a volunteer army under Gen. Felix Huston, Col. Edward Burleson, Capt. Mathew Caldwell, and others and with Texas Rangers under Ben McCulloch overtook the Indians at Plum Creek in the vicinity of the present town of Lockhart on August 11, 1840. There a decisive defeat on the following day pushed the Comanches westward.
