Part of the Apache Wars
"On three occasions – April or August 1878; September 1881; and May 1885 – Geronimo led his band of followers in breakouts from the reservation to return to their former nomadic life associated with raiding and warfare. Following each breakout, Geronimo and his band would flee across Arizona and New Mexico to Mexico, killing and plundering as they went, and establish a new base in the rugged and remote Sierra Madre Occidental Mountains. In Mexico, they were insulated from pursuit by U.S. armed forces. The Apache knew the rough terrain of the Sierras intimately, which helped them elude pursuit and protected them from attack. The Sierra Madre mountains lie on the border between the Mexican states of Sonora and Chihuahua, which allowed the Apache access to raid and plunder the small villages, haciendas, wagon trains, worker camps and travelers in both states. From Mexico, Apache bands also staged surprise raids back into the United States, often seeking to replenish their supply of guns and ammunition. Utley refers to a specific raid in March 1883, in which Geronimo's people split up with Geronimo and Chihuahua raiding in the Sonora River valley to collect livestock and provisions, while Chatto and Bonito raided through southern Arizona to gather weapons and cartridges. In these raids into the United States, the Apaches moved swiftly and attacked isolated ranches, wagon trains, prospectors and travelers. They often killed all the persons they encountered in order to avoid detection and pursuit as long as possible before they slipped back over the border into Mexico.
The "breakouts" and the subsequent resumption of Apache raiding and warfare caused the Mexican Army and militia as well as United States forces to pursue and attempt to kill or apprehend off-reservation "renegade" Apache bands, including Geronimo's, wherever they could be found. Because the Mexican army and militia units of Sonora and Chihuahua were unable to suppress the several Chiricahua bands based in the Sierra Madre mountains, in 1883 Mexico allowed the United States to send troops into Mexico to continue their pursuit of Geronimo's band and the bands of other Apache leaders.
Geronimo and his followers had little or no time to rest or stay in one place. Completely worn out, the small band of Apaches returned to the U.S. with Lawton and officially surrendered to General Miles on September 4, 1886, at Skeleton Canyon, Arizona.
When Geronimo surrendered, he had in his possession a Winchester Model 1876 lever-action rifle with a silver-washed barrel and receiver, bearing Serial Number 109450. It is on display at the United States Military Academy, West Point, New York. Additionally, he had a Colt Single Action Army revolver with a nickel finish and ivory stocks bearing Serial Number 89524, and a Sheffield Bowie knife with a dagger type blade and a stag handle made by George Wostenholm in an elaborate silver-studded holster and cartridge belt. The revolver, rig, and knife are on display at the Fort Sill museum." - https://en.wikipedia.org/wiki/Geronimo#Geronimo_campaign
