The significant event that took place at the Alamo in 1836 was a pivotal battle during the Texan independence movement. A small group of Texian defenders, including notable figures like James Bowie and Davy Crockett, held out against a much larger Mexican army led by General Antonio López de Santa Anna. Despite the ultimate defeat of the defenders after a 13-day siege, the Alamo became a symbol of resistance and martyrdom in the fight for Texan independence. The phrase "Remember the Alamo!" became a rallying cry for Texians, motivating them to ultimately defeat the Mexican forces and secure Texas's independence later that year.
