On Feb. 23, the first elements of the Mexican army arrived in San Antonio, led by Santa Anna. Over the next twelve days, more and more units arrived and the force swelled to over 4,000. The history of the siege became a matter of legend. Some historians say, no one really knows if Col. William B. Travis on day six and some say day 12, Feb. 28 or Mar. 5, 1836, drew a line in the sand and explained to the defenders three possibilities. The first, was to surrender and be executed. The second, was to try and fight their way out and many would be butchered by Santa Anna’s cavalry lancers. The Third, cross the line, defend the fort, resist the attacks, and make Santa Anna’s soldiers pay dearly. Legend says that he began his speech this way. “We must die, our business is not to make a fruitless effort to save our lives, but to choose the manner of our death,” Travis said.
