1836 – Texas Revolution: The Battle of the Alamo begins in San Antonio, Texas
. When Mexican troops departed San Antonio de Béxar (now San Antonio, Texas, USA) Texian soldiers established a garrison at the Alamo Mission, a former Spanish religious outpost which had been converted to a makeshift fort by the recently expelled Mexican Army. Described by Santa Anna as an "irregular fortification hardly worthy of the name," the Alamo had been designed to withstand an attack by native tribes, not an artillery-equipped army. The Battle of the Alamo (February 23 – March 6, 1836) was a pivotal event in the Texas Revolution. Following a 13-day siege, Mexican troops under President General Antonio López de Santa Anna launched an assault on the Alamo Mission near San Antonio de Béxar (modern-day San Antonio), Texas, United States, killing all of the Texian defenders. Santa Anna's cruelty during the battle inspired many Texians—both Texas settlers and adventurers from the United States—to join the Texian Army. Buoyed by a desire for revenge, the Texians defeated the Mexican Army at the Battle of San Jacinto, on April 21, 1836, ending the revolution.
