Title: History of San Antonio
Content:  After Mexico won independence from Spain in 1821, Anglo American settlers, at the invitation of the Mexican government via Empresarios such as Stephen F. Austin, began to settle in Texas in areas east and northeast of San Antonio. When Antonio López de Santa Anna, after being elected President of Mexico in 1833, rescinded the Mexican Constitution of 1824, violence ensued in many provinces of Mexico. In Texas the Anglo settlers joined many Hispanic Texans, who called themselves Tejanos, in demanding a return to the Constitution of 1824. In a series of battles the Anglo Texans, who called themselves Texians, supported by a significant number of Tejano allies, initially succeeded in forcing the Mexican military to retreat from Texas. Under the leadership of Ben Milam, in the Battle of Bexar, December, 1835, Texian forces captured San Antonio from forces commanded by General Martin Perfecto de Cos, Santa Anna's brother-in-law. Forces opposing Santa Anna took control of the entire province of Texas. Today Milam Park and the Cos House in San Antonio commemorate this battle.

After a separate favorable Texian engagement earlier in the day, a reinforcement company of 54 Texas militia, mostly from Fayette County, under the command of Nicholas Mosby Dawson, began advancing on the rear of the Mexican Army. The Mexican commander, General Adrián Woll, sent 500 of his cavalrymen and two cannons to attack the group. The Texians held their own against the Mexican soldiers, but their fatalities mounted after the cannons came within range.
