main reasons Mexico had encouraged Americans to settle in Texas in the 1820s and 1830s was because they wanted a buffer against Comanches, a sort of insurance policy on their borderlands. In that sense, the Alamo, Goliad, San Jacinto, and the birth of the Texas republic were the product of a misguided scheme to stop the Comanches. No one knew this, either. Certainly not settlers like the Parkers who were, in effect, being offered up as meat for Comanche raiders.
