Battle context

The Battle of San Jacinto was the decisive engagement of the Texas Revolution, ending the conflict in a Texan victory. Under General Sam Houston, the Texan Army defeated General Antonio López de Santa Anna's Mexican force—numbering approximately 1,360 men—in a engagement that lasted just 18 minutes. Mexican casualties ranged from 208 to 630. The speed and completeness of the Texan victory effectively ended organized Mexican military resistance and determined the outcome of the revolution. Houston's account, written from the San Jacinto headquarters on April 25, 1836, stands as the primary first-hand record of the engagement, and the battle has since attracted extensive secondary analysis as the culminating moment of Texas's break from the Centralist Republic of Mexico.
