The expedition established its headquarters in San Juan, and from there Oñate sent Gaspar Pérez de Villagrá and his other captains into expeditions in search of towns, riches, and resources. The first Spanish settlers in New Mexico moved from San Juan in 1598, to the river valley settlement of San Gabriel in 1601, then to a spot twenty miles south at the foot of the Sangre de Cristo mountain range, named Sante Fe in 1607. The expeditions found nothing and the settlers he had brought became discontent with the quest, some deciding to leave. As a demonstration of disapproval, Oñate ordered the execution of some of the settlers who led the dissent.
