Many fought for slavery, (Travis was an ex-slave dealer from Louisiana, I believe, and stayed at the Alamo despite orders from Houston to get out of an undefendable trap) many fought against despotism. Santa Anna was marching to Texas from Jalisco where he had just put down a similar insurrection. After victory, he turned his army loose on the city. Estimates run as high as 20,000 civilians slaughtered. Davy Crockett was a fascinating fellow and a unique individual. I wish I still had my coonskin cap.
