For the next twelve days, the Alamo lay under siege. Santa Anna planned an early morning assault for March 6. At 8:10 pm on March 5 the Mexican artillery ceased their bombardment. As Santa Anna had planned, the exhausted Texans soon fell into the first uninterrupted sleep many had had since the siege began. At 5:30 am Santa Anna gave the order to advance. As the Mexican soldiers began to yell and their buglers sounded, the Texan defenders awakened and rushed to their posts. Susanna, Angelina, and most other noncombatants gathered in the chapel sacristy for safety. She later mentioned that Davy Crockett stopped briefly to pray before taking his assigned position.
