The official Alamo website tries to correct the persistent myth that everyone died at the Alamo. “It is true that nearly all of the Texans under arms inside the fort were killed in the March 6, 1836, attack. However, nearly twenty women and children, who experienced the twelve days of siege leading to the final assault, were spared and allowed to return to their homes." Also spared were the slave of William Travis, named Joe and Susanna Dickinson. See official website for more.
