ON THIS DAY

March 6, 1836:

The Battle of the Alamo (February 23 – March 6, 1836) was a pivotal event and military engagement in the Texas Revolution. Following a 13-day siege, Mexican troops under President General Antonio López de Santa Anna reclaimed the Alamo Mission near San Antonio de Béxar (modern-day San Antonio, Texas, United States). About one hundred Texians were then garrisoned at the mission, with around a hundred subsequent reinforcements led by eventual Alamo co-commanders James Bowie and William B. Travis. 

On February 23, approximately 1,500 Mexicans marched into San Antonio de Béxar as the first step in a campaign to retake Texas. In the early morning hours of March 6, the Mexican Army advanced on the Alamo. After repelling two attacks, the Texians were unable to fend off a third attack. As Mexican soldiers scaled the walls, most of the Texian fighters withdrew into interior buildings. Those who were unable to reach these points were slain by the Mexican cavalry as they attempted to escape. Between five and seven Texians may have surrendered; if so, they were quickly executed. Subsequently almost all of the Texian inhabitants were killed.

Santa Anna's execution of surrendering soldiers during the battle inspired many Texians and Tejanos to join the Texian Army. Motivated by a desire for revenge, as well as their written desire to preserve a border open to immigration and the importation and practice of slavery, the Texians defeated the Mexican Army at the Battle of San Jacinto, on April 21, 1836.

In 19th-century Texas, the Alamo complex gradually became known as a battle site rather than a former mission. The Texas Legislature purchased the land and buildings in the early part of the 20th century and designated the Alamo chapel as an official Texas State Shrine.
