Only a handful had survived when they reached the banks of the Brazos River. The most perilous part of the journey remained: Comancheria—Comanche Territory. The Spaniards built a raft to float down the Brazos to safety. They made it to Cyclone Bend when the Comanche caught up with them. The Spaniards sought refuge in the bluffs of the Brazos, hiding in the caves in what is now known as Bruton Canyon. The Comanche besieged them and were eventually able to collapse the cave burying the Spaniards and their gold. The gold was never found — leaving hidden treasure along the banks of the Brazos River.
