"Anza worked to secure Ecueracapa's [Leather Cape's] preeminent position as captain general of the entire Comanche nation. And he succeeded. By April 1787, he had in hand a final treaty with all three branches. Ecueracapa had gone after Apaches and sent in tally sheets of his kills. His people had come again to trade at Pecos. Despite the replacement of Anza in 1787 and the death of Ecueracapa in 1793, despite the utter failure of the Jupes to settle down in the pueblo they asked the Spaniards to build for them on the Arkansas, despite troublesome hostilities of Utes, Navajos, and Jicarillas with Comanches, the alliance of Comanches and Spaniards embarked upon at Pecos in 1786 stood unbroken for a generation."
