"By 1700 the unmatched mobility and power of the horse was transforming the Indian's way of life, including warfare. Nuevo Santander and other parts of New Spain were in frequent danger from raids by mounted Apache and Comanche warriors. Defense, thus, was a routine part of life for Escandón's colonists. To help save the expense of large numbers of royal troops, the settlers were expected to bear arms when necessary, as militia. Most villas had about a dozen of these citizen-soldiers, under the village capitán's authority."
