Facts About the Battle of San Jacinto

The Battle of San Jacinto was a decisive event in the Texas Revolution, fought on April 21, 1836, near present-day Houston, Texas. Led by General Sam Houston, the Texan army launched a surprise attack against Mexican forces commanded by General Antonio López de Santa Anna. The battle resulted in a major Texan victory and helped secure Texas independence from Mexico.

The Battle of San Jacinto Was Decided in Just 18 Minutes

One of the most remarkable facts about the Battle of San Jacinto is how quickly the main fighting ended. On the afternoon of April 21, 1836, approximately 900 Texan soldiers advanced toward the Mexican camp while many of Santa Anna's troops were resting.

The Texans launched a sudden assault, catching the Mexican army largely unprepared. The organized fighting lasted approximately 18 minutes, although the pursuit of fleeing Mexican soldiers continued afterward. This brief confrontation became one of the most consequential military victories in Texas history.

Roughly 600 Mexican Soldiers Were Captured After San Jacinto

Following the Texan victory, hundreds of Mexican soldiers were taken prisoner. Historical accounts commonly report that approximately 600 Mexican troops were captured during and after the battle.

Among those captured was General Santa Anna, who was discovered the following day while attempting to escape. His capture proved especially important because he was both the commander of the Mexican forces and the president of Mexico. While held prisoner, Santa Anna signed agreements that called for the withdrawal of Mexican troops from Texas.

Around 630 Mexican Soldiers Were Killed at San Jacinto

The Battle of San Jacinto resulted in heavy casualties for the Mexican army. According to General Sam Houston's official report, approximately 630 Mexican soldiers were killed, while another 730 were captured. By comparison, the Texan army suffered nine deaths or mortal wounds and approximately 30 additional injuries.

Many Mexican casualties occurred after the initial fighting ended, as Texan soldiers pursued retreating troops. The Texans' anger over earlier events, particularly the Battle of the Alamo and the Goliad Massacre, contributed to the intensity of the fighting.

Why the Battle of San Jacinto Was Important

The Battle of San Jacinto effectively ended the major military campaign of the Texas Revolution. Santa Anna's capture and the subsequent agreements helped bring about the withdrawal of Mexican forces from Texas, although Mexico did not formally recognize Texas independence at the time.

The victory allowed the Republic of Texas to establish itself as an independent nation. Texas remained a republic until joining the United States in 1845. Today, the San Jacinto Monument and surrounding battleground preserve the history of this important event.
