In 1832 he visited Washington in the interest of the western Cherokee, calling in Indian costume upon President Jackson, who received him with old-time friendship. Being accused while there of connection with a fraudulent Indian contract, he administered a severe beating to his accuser, a member of Congress. For this he was fined $500 and reprimanded by the bar of the House, but Jackson remitted the fine. Soon after his return to the West he removed to Texas to take part in the agitation just started against Mexican rule. He was a member of the convention which adopted a separate constitution for Texas in 1833, and two years later aided in forming a provisional government, and was elected commander-in-chief to organize the new militia. In 1836 he was a member of the convention which declared the independence of Texas. At the battle of San Jacinto in April of that year he defeated with 750 men Santa Ana's army of 1,800, inflicting upon the Mexicans the terrible loss of 630 killed and 730 prisoners, among whom was Santa Ana himself. Houston received a severe wound in the engagement. In the autumn of the same year he was elected first president of the republic of Texas, receiving more than four-fifths of the votes cast. He served two years and retired at the end of his term, leaving the country on good terms with both Mexico and the Indian tribes, and with its notes at par. He was immediately elected to the Texas congress and served in that capacity until 1841, when he was reelected president. It was during these years that he made his steadfast fight in behalf of the Texas Cherokee, as is narrated elsewhere, supporting their cause without wavering, at the risk of his own popularity and position. He frequently declared that no treaty made and carried out in good faith had ever been violated by Indians. His Cherokee wife having died some time before, he was again married in 1840, this time to a lady from Alabama, who exercised over him a restraining and ennobling influence through the stormy vicissitudes of his eventful life. In June, 1842, he vetoed a bill making him dictator for the purpose of resisting a threatened invasion from Mexico.
