Alamo - Mexican army
During the winter of 1835-1836, the people of Texas decided to sever their relations with Mexico because of dissatisfaction with the Mexican government. To prevent the success of this independence movement, General Antonio Lopez de Santa Anna, in command of the Mexican Army, approached San Antonio with his troops. Lieutenant Colonel William Barret Travis and a force of about 150 Texans sought to defend the city. The company included the famous frontiersmen James Bowie and Davy Crockett.

The siege of the Alamo lasted 13 days. By March 5, the garrison could not return Mexican fire because ammunition was low. This convinced Santa Anna that the fort could be assaulted. Early the next morning, the Mexicans succeeded in scaling the walls. At the end, the Texans fought using their rifles as clubs. Some historians believe that a few defenders, perhaps including Crockett, survived the battle only to be executed at Santa Anna's orders.
