The Battle of the Alamo, which took place from February 23 to March 6, 1836, was a pivotal event in the Texas Revolution, where a small group of approximately 189 defenders, including famous figures like Davy Crockett and Jim Bowie, fought against a much larger Mexican army led by General Santa Anna. The battle resulted in the deaths of nearly all the defenders, but it galvanized support for the revolution, which ultimately led to the defeat of the Mexican army at the Battle of San Jacinto on April 21, 1836.
