Battle of the Alamo, battle during the Texas Revolution that occurred from February 23 to March 6, 1836, in San Antonio, Texas. It ended in a decisive victory for Mexican forces over Texan volunteers.

The Mexican Army, led by General Antonio López de Santa Anna, won the Battle of the Alamo. The siege lasted for 13 days, ending on the morning of March 6, 1836. The Texian defenders, including famous figures like James Bowie, William B. Travis, and David Crockett, were completely overwhelmed by the superior numbers of the Mexican force. Virtually all of the combatant defenders—roughly 180 to 250 men—were killed in the final assault. While it was a decisive military victory for Mexico, it became a strategic blunder for Santa Anna. The "sacrifice" of the Alamo defenders became a powerful rallying cry—"Remember the Alamo!"—which galvanized the Texian spirit and attracted more volunteers to the cause. Just weeks later, the Texian army led by Sam Houston defeated Santa Anna’s forces at the Battle of San Jacinto, securing Texas's independence. Thus, while Mexico won the battle, the event directly led to them losing the war and, eventually, the territory of Texas.
