The Battle of San Jacinto: Eighteen Minutes That Made a Country

The battle that created the Republic of Texas lasted eighteen minutes. The killing that followed lasted considerably longer.

By April of eighteen thirty-six, the Texas Revolution appeared to be failing. The Alamo had fallen in early March. In late March, Mexican troops executed Colonel James Fannin and more than three hundred Texian prisoners at Goliad, a massacre that sent a shudder through the settler population and sparked a mass flight eastward known as the Runaway Scrape. Sam Houston, commanding a ragged army of volunteers, retreated for weeks, drawing sharp criticism for what many called cowardice.

Houston had a plan. He chose this ground carefully: a low peninsula at the confluence of Buffalo Bayou and the San Jacinto River, sheltered by trees on one side and marsh on the other. Santa Anna, who had split his forces, arrived with about seven hundred men and made camp nearby on the afternoon of April twentieth. He expected Houston to attack that day. Houston did not.

On the afternoon of April twenty-first, as the Mexican forces rested during siesta, Houston ordered his men forward. He also sent his famous scout Erastus Smith, known as Deaf Smith, to destroy Vince's Bridge behind them. Both armies were now trapped on the same peninsula. There was no retreating for anyone.

The Texian line moved across the open prairie at three-thirty in the afternoon, then broke into a run. The Mexican camp was caught completely unprepared. In eighteen minutes of combat, the Mexican force was shattered. More than six hundred Mexicans were killed and over seven hundred captured. Houston lost nine men dead. Santa Anna himself was captured the following morning, hiding in marsh grass dressed in a private's uniform. A fellow prisoner called out his name, and that was that.

Under duress, Santa Anna signed the Treaties of Velasco, agreeing to withdraw Mexican forces and recognize Texas independence. Mexico never formally ratified the agreement, and the boundary dispute this left behind would eventually ignite the Mexican-American War a decade later. But on the afternoon of April twenty-first, eighteen thirty-six, on this piece of marshy ground near the Houston Ship Channel, the battle cries of Remember the Alamo and Remember Goliad became, for a few hours at least, the sound of a nation being born.
