After the peace treaty, Cochise retired to his new reservation, the short-lived Chiricahua Reservation (1872-1876), with his friend Jeffords as agent. Cochise died of natural causes (probably abdominal cancer) in 1874. He was buried in the rocks above one of his favorite camps in Arizona's Dragoon Mountains, now called the Cochise Stronghold. Only his people and Tom Jeffords knew the exact location of his resting place, and they took the secret to their graves.
