As early as October 27, Mexican president Antonio Lopez de Santa Anna had been preparing to quell the unrest in Texas. In early 1836, Santa Anna personally led a 6,000-man force toward Texas. His force was large but ill-trained. Santa Anna led the bulk of the troops to San Antonio de Bexar to besiege the Alamo Mission, while General Jose de Urrea led the remaining troops up the coast of Texas. Urrea's forces soon defeated all the Texian resistance along the coast, culminating in the Goliad Massacre, where they executed 300 Texian prisoners of war. After a thirteen-day siege, Santa Anna's forces overwhelmed the nearly 200 Texians defending the Alamo, and killed the prisoners. "Remember the Alamo! Remember Goliad!" became a battle cry of the Texas Revolution.
