 Although the Comanches and their Wichita allies were never able to breach the presidio's walls, their constant harassment of patrols, supply trains, and foragers made life at the presidio unbearable.Conditions deteriorated to the point that Captain Rábago abandoned the post without authorization in June 1768, evacuating the garrison, women, and children to the relative safety of Mission San Lorenzo de la Santa Cruz.For this action he, too, was relieved of command, and replaced by Captain Manuel Antonio de Oca.
