But in 1840 trouble broke out again with the Comanches. Twelve chiefs of this tribe came to San Antonio to sign a new treaty. As usual, they were accompanied by their women and children. They had promised to bring with them thirteen white prisoners, but they appeared with but one, a little girl named Matilda Lockhart, who had been carried away in a raid on her father’s house two years before. The chiefs declared they had no more prisoners. But the child said there were others at the camp, who were to be brought in one by one for large ransom. A company of soldiers was ordered into the council-room, and the Indians were told that they were prisoners until the other white captives were given up. One of the chiefs immediately attempted to escape, stabbing the sentinel at the door. A furious combat followed, in which the twelve chiefs were all killed. In the plaza outside there was also a desperate fight. The Indian women took part in this, and three of them were killed. Captain Matthew Caldwell, who was unarmed, defended himself with stones until his assailant was killed. Judge Thompson, who had been playing with the Indian children, setting up pieces of money for them to shoot at, was slain by an arrow from one of their bows. Colonel Wells came riding into the plaza in the midst of the skirmish. A powerful Indian leaped on his horse behind him and tried to shake him off. Unable to do this he seized the bridle and tried to guide the horse out of the plaza. Colonel Wells’s arms were pinioned so that he could not draw his pistol, and it was only after careering thus several times around the plaza that the Indian was shot by a soldier and the Colonel released. The band was finally overpowered. Thirty-two warriors, three squaws, and two children were killed; the others were all made prisoners. This encounter is known as the “Council-house Fight.” Congress held its meetings in Houston until 1839. But the site for a new capital had been chosen. It was on the banks of the Colorado River, on the then extreme frontier. Two or three pioneer cabins already stood there, and the little settlement bore the proud name of Waterloo. But bands of savage Indians still roamed the hills and prairies adjacent. It was necessary to place guards about the grounds to protect the masons and carpenters while they were at work on the capitol building. Among the buildings erected was a blockhouse, as a refuge for the women and children in case of an Indian raid. The new capital was named Austin, in grateful memory of the Father of Texas. Congress met at Austin for the first time in October, 1839. Among the important acts of this session was the appropriation of fifty leagues of land for a state university, and three leagues to each county for schools. This Congress also adopted a national flag, the same now used as the Texas state flag.
