On February 23, 1836, General Antonio López de Santa Anna marched an army through inclement weather, including snowstorms in mountain passes, against the Texas rebellion. The city of San Antonio de Bexar was one of his intermediate objectives; his ultimate objective was to capture the Texas government and restore the rule of the central Mexican government over a rebellious territory, as he had over the State of Zacatecas the previous year.
The Alamo, originally named Mision San Antonio de Valero, served as a home for converted Indians and their Christian missionaries in the late 1700s. Throughout the later years and up to the 1830s, the mission would become a home for various outfits including revolutionaries, rebels, and then eventually Mexican citizens.

Thus, it was decided by Mexican generals to attack the Alamo garrison in February of 1836. It would be a 13-day long affair that climaxed on March 6 with the capture of the mission and the death of nearly all of the Texian defenders.
