Some viewed Santa Annaâs overthrow of the Mexican Republic as an opportunity to break away and form an independent Republic of Texas that might one day become an American state. Determined to crush the Texas rebels, Santa Anna took command of the Mexican army that invaded Texas in 1836. His forces successfully defeated the Texas rebels at the Alamo, and he personally ordered the execution of 400 Texan prisoners after the Battle of Goliad.
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.
