The Texas Revolution had officially begun on October 2 and by the end of the month the Texans had initiated a siege of Béxar, home of the largest Mexican garrison in the province. Bored with the inactivity, many of the Texan soldiers returned home; a smaller number of adventurers from the United States arrived to replace them. After the Texan Army rejected commander-in-chief Stephen F. Austin's call to launch an assault on Béxar on November 22, Austin resigned from the army.
