In 1849, Buffalo Hump escorted Robert S. Neighbors and John S. “Rip” Ford’s expedition along the first part of the trail from San Antonio to El Paso, as far as the Nokoni villages, Yellow Wolf and Shanaco (son of a chief killed in the Council House of San Antonio) joining him; at the Nokoni villages Buffalo Hump and Yellow Wolf entrusted their proteges to their old friend Huupi-pahati, the Nokoni chief, who brought the whites to their destination. In 1851 Yellow Wolf and Buffalo Hump, again together in the field, led their warriors in a great raid into Mexico, raiding the states of Chihuahua and Durango.
