Robert Jenkins Onderdonk, Fall of the Alamo, 1903, Texas State Archives.

March 6, 1836: Following a thirteen-day siege, more than 2000 Mexican troops launched a pre-dawn attack from all four sides on the fortress defended by 180 men. The Mexicans were repulsed twice, but a third assault gained the north wall and broke through the west wall. After fierce fighting, the defenders were killed to a man. The casualties included Colonel William Barret Travis, James Bowie, and former Congressman from Tennessee David Crockett.
