In December 1835, in the early stages of Texas’ war for independence from Mexico, a group of Texan (or Texian) volunteers led by George Collinsworth and Benjamin Milam overwhelmed the Mexican garrison at the Alamo and captured the fort, seizing control of San Antonio. By mid-February 1836, Colonel James Bowie and Lieutenant Colonel William B. Travis had taken command of Texan forces in San Antonio. Though Sam Houston, the newly appointed commander-in-chief of the Texan forces, argued that San Antonio should be abandoned due to insufficient troop numbers, the Alamo’s defenders–led by Bowie and Travis–dug in nonetheless, prepared to defend the fort to the last. These defenders, who despite later reinforcements never numbered more than 200, included Davy Crockett, the famous frontiersman and former congressman from Tennessee, who had arrived in early February.
On February 23, a Mexican force comprising somewhere between 1,800 and 6,000 men (according to various estimates) and commanded by General Antonio Lopez de Santa Anna began a siege of the fort. The Texans held out for 13 days, but on the morning of March 6 Mexican forces broke through a breach in the outer wall of the courtyard and overpowered them. Santa Anna ordered his men to take no prisoners, and only a small handful of the Texans were spared. One of these was Susannah Dickinson, the wife of Captain Almaron Dickinson (who was killed) and her infant daughter Angelina. Santa Anna sent them to Houston’s camp in Gonzalez with a warning that a similar fate awaited the rest of the Texans if they continued their revolt. The Mexican forces also suffered heavy casualties in the Battle of the Alamo, losing between 600 and 1,600 men.
