From the official website of the Alamo:
"The final assault came before daybreak on the morning of March 6, 1836, as columns of Mexican soldiers emerged from the predawn darkness and headed for the Alamo's walls. Cannon and small arms fire from inside the Alamo beat back several attacks. Regrouping, the Mexicans scaled the walls and rushed into the compound. Once inside, they turned a captured cannon on the Long Barrack and church, blasting open the barricaded doors. The desperate struggle continued until the defenders were overwhelmed. By sunrise, the battle had ended and Santa Anna entered the Alamo compound to survey the scene of his victory.
While the facts surrounding the siege of the Alamo continue to be debated, there is no doubt about what the battle has come to symbolize. People worldwide continue to remember the Alamo as a heroic struggle against impossible odds — a place where men made the ultimate sacrifice for freedom. For this reason, the Alamo remains hallowed ground and the Shrine of Texas Liberty."
