On March 6, 1836, just five days after delegates had declared their independence from Mexico during a meeting in Washington-on-the-Brazos, the fortified compound of San Antonio de Valero Mission, under siege for thirteen days by the Mexican army under General Antonio Lòpez de Santa Anna, was subjected to an early morning assault. After a fierce battle, the defenses of the Alamo were overrun and all the defenders were killed. The slogan "Remember the Alamo!" became a rallying cry for the Texas Revolution.”
