Following a 13 - day siege, Mexican troops under President General Antonio López de Santa Anna launched an assault on the Alamo Mission near San Antonio de Béxar (modern - day San Antonio, Texas, United States), killing all of the Texian defenders . Santa Anna's cruelty during the battle inspired many Texians--both Texas settlers and adventurers from the United States--to join the Texian Army . Buoyed by a desire for revenge, the Texians defeated the Mexican Army at the Battle of San Jacinto, on April 21, 1836, ending the revolution . </P> <P> Several months previously, Texians had driven all Mexican troops out of Mexican Texas . About 100 Texians were then garrisoned at the Alamo . The Texian force grew slightly with the arrival of reinforcements led by eventual Alamo co-commanders James Bowie and William B. Travis . On February 23, approximately 1,500 Mexicans marched into San Antonio de Béxar as the first step in a campaign to retake Texas . For the next 10 days, the two armies engaged in several skirmishes with minimal casualties . Aware that his garrison could not withstand an attack by such a large force, Travis wrote multiple letters pleading for more men and supplies, but the Texians were reinforced by fewer than 100 men . </P>
