Susannah and her husband, Almaron, joined a group of volunteers who helped to secure San Antonio de Bexar as a stronghold for the Texans after the Battle of Gonzales in 1835. It was here, in 1836, that her husband lost his life and Susannah would endure the ordeal of the siege. She was interviewed by Santa Anna himself following the fall of the Alamo and released. After heading eastward from San Antonio, she was found by Deaf Smith and Henry Karnes, scouts for the Texas army. Susannah died on October 7, 1883, and is buried in Austin.
