After being forced to swear loyalty to Olid, they were released. After the death of Olid, Spanish relations with the natives of Naco deteriorated notably. The survivors were captured by Olid. Las Casas secretly sent messages to Briones, attempting to buy his support against Olid. His ships limped into the bay at Triunfo, where Olid had established his headquarters. Olid sent Briones to conquer more territory. Under the circumstances, Olid proposed a truce. Olid next marched inland to the Naco Valley. Nevertheless, Olid decided to launch an attack with two caravels. Olid was executed by having his throat cut in the plaza at Naco. Olid managed to capture his rivals, but was betrayed by his men and assassinated.
