The historian T.R. Fehrenbach postulated that the unique character of Texas came from one thing which differentiated it from other trans-Mississippi states; that it was in a constant state of war for the best part of half a century and so the readiness to fight for life at a moment’s notice became ingrained. Usually the fight was with the Comanches, who lived for war, plunder and ransom. While the Anglo settlers occasionally took a break from fighting to farm or ranch, or take up some peaceable trade, the Comanches never did; there was no other means of advancing in their culture, save being a fearless warrior and raider. At the high noon-time of their peak, they were the lords of the southern plains, from the Arkansas River to the Balcones Escarpment, having ruthlessly pushed other tribes out the Tonkawa, Lipan Apache, the Karankawa and others. The Comanche ranged and raided as far as they pleased, occasionally interrupted by a fragile peace treaty.
A relative period of peace between the Penateka, or southern Comanche, and the Republic of Texas came to a spectacularly violent end in the spring of 1840 during the course of what had been intended as a peace conference in San Antonio. A contingent of chiefs and Texan peace commissioners met in a large building adjoining the town jail, on Main Plaza and Market Street. In token of their good faith, the chiefs had promised or led the Texans to believe they had been promised to turn over a number of captives, and sign a peace treaty. But the Penateka only released one; a teenaged girl, Matilda Lockhart, who had been savagely abused, raped and mutilated during a year of captivity. She told the disappointed and outraged Texan officials that the Comanches camped outside the town held more than a dozen other captives, including her own sister, but meant to extort large ransoms for each. When the chiefs and the peace commissioners met again, the commissioners asked about the other captives. The leader of the chiefs answered that they had brought in the only one they had. The others were with other tribes. And then he added, insolently, “How do you like that answer?”
