On February 23, 1836, after a grueling winter march, General Antonio LÃ³pez de Santa Anna and his army arrived at San Antonio to put down the frontier rebellion. The Texian rebels withdrew across the San Antonio River into the safety of the old fortified mission known as the Alamo.
Santa Anna crossed the Rio Grande on February 12, and - a month earlier than expected - he arrived outside Bexar on February 23. Travis dispatched a note to Gonzales calling for reinforcements and numbering the defenders at 150. The next day he wrote his Letter from the Alamo, probably the best known of all Texas documents. Reinforcements under Captain Albert Martin arrived from Gonzales on March 1. With the arrival of the last of Santa Anna's forces, Travis was able to send out only one last appeal on March 3.
