Sunday, March 6, 1836. At around 5 a.m., Gen. Antonio López de Santa Anna ordered the assault on the Alamo. Approximately 1,800 Mexican troops advanced on the small American garrison, some 200 men, inside that mission fort. Though the Alamo’s defenders were exhausted from the 12 previous days of siege warfare, and with the walls of their fortress battered and beginning to break apart, their cannon and rifle fire twice staggered the Mexican advance. Then, the lines re-formed for a third time, the attackers charged forward, and soon they were inside the fort’s perimeter.
