The Heroes of the Alamo knew that they would not reinforced nor assisted in their battle. There job was to delay Santa Anna as long as possible to allow Sam Houston and the Texas Army more time to establish their force for a later battle.
The brutal slaughter of the Mexican Army at San Jacinto was pay-back for what happened at the Alamo, Gonzales and other Villages and Posts.

I knew what Deguello meant long before ZZ Top named their album.
