Santa Anna was a member of the same tribe of the Comanche as the more famous Buffalo Hump. He was an important chief, though probably less influential than Buffalo Hump, if not, perhaps, than this one's cousin Yellow Wolf, during the 1830s and 1840s. He was the first member of his tribe to visit Washington, D.C. He was originally, along with Buffalo Hump and Yellow Wolf, a leader of Comanche resistance to Anglo settlement in Texas, especially during the period following the Council House Fight. He was the father ofCarne Muerto, later a War Chief of the Quahadi tribe of Comanche. Santa Anna, "a large, fine-looking man with an affable and lively countenance," rose to prominence in the years following the Texas Revolution. Ferdinand Roemer, a noted German scientist who was traveling in the Americas at the time of the meetings in the mid and late 1840s, attended the council between the chiefs and white representatives. He described the three Comanche chiefs present as 'serene and dignified,' characterizing Old Owl as 'the political chief' and Santa Anna as an affable and lively-looking 'war chief'.
Following the deadly Council House Fight, where the Comanche felt that the whites had slaughtered their envoys despite the promise of the white treaty flag, conflict between Comanches and migrating Anglo-Texans had become increasingly frequent. Santa Anna advocated armed and bitter resistance to the white invasion of the Comancheria, and gained prominence after the Council House Fight in San Antonio in 1840. For approximately the next five years he joined Buffalo Hump and a number of other war chiefs in conducting a series of raids and attacks on Anglo settlements, including the Great Raid of 1840, during which the Comanche burned two cities, and raided all the way to the sea. Though it is today impossible to trace his direct involvement with any sort of precision, Santa Anna probably took part in the raids on Linnville and Victoria in 1840 and may have been present at the Battle of Plum Creek. Prior to 1845 he was firmly identified with the faction of his tribe that opposed accommodation with whites.
Santa Anna became a proponent of accommodation and peace with the whites following his involvement with treaty talks with the Army, and a later visit to Washington, D.C. in 1847. Before 1845 he was firmly identified with the militant faction of his tribe that opposed accommodation with whites. In point of fact, there is absolutely no record of his ever meeting with officials representing the government of the Republic of Texas. He appeared during this time to be even more militant than Buffalo Hump, who had met with Sam Houston in 1843–44. But in the later part of 1845, he was finally convinced to attend treaty negotiations conducted by United States officials, where he was first exposed to the true numbers and weaponry of the whites. Santa Anna, more than any other Native American of the Plains during this time, was influenced by what he had seen. Convinced that his people could simply not defeat or long resist the numbers and weapons of the whites, he began advocating peace. In May 1846 he was one of those Comanche Chiefs who signed a treaty promising peace between his people and American citizens in Texas. Geologist Dr. Ferdinand von Roemer was present at those treaty talks, which resulted in the Meusebach-Comanche Treaty, and left an enduring and vivid portrait of Santa Anna: In early December 1847, Santa Anna and a party of chiefs from several tribes in Texas visited Washington, D.C. The first of his tribe to make such a journey, Santa Anna was recorded to be overwhelmed by what he saw, especially the sheer numbers of the whites. From that moment on, convinced that continued armed resistance against the United States was tantamount to suicide for his people, he began advocating accommodation and attempted to use his prestige as a noted War Chief to secure a lasting peace. But among the still-warlike Comanche, Santa Anna's conversion reduced his prestige.
Death
Santa Anna apparently tired of his reduced position, and to regain his former glory he led several raids into Mexico in 1848–49. These raids necessitated intervention by the army and United States Indian agent Robert S. Neighbors, and Santa Anna was persuaded to halt the raids. In late December 1849, a cholera epidemic killed over 300 Penateka Comanche in a few weeks time. Santa Anna was one of the victims, though Buffalo Hump, also ill, survived. Following Santa Anna's death, those in the Penateka tribe, other than the division commanded by Buffalo Hump, disintegrated. Its surviving members joined other Comanche tribes.
