After extreme patience, on April 21, 1836, Sam Houston strikes at Santa Anna. The Battle of San Jacinto was quick and decisive. In under 20 minutes the Texian army killed 600 Mexicans and captured another 700. Texians death were under 10. Santa Anna cowered after the defeat, disguising himself as a private before being noticed in the makeshift POW camp. He negotiated for his life, and against the wishes of many, Houston arranged for his return to Mexico. The war was effectively over and the Republic of Texas was founded.
