The Apache Campaign of 1896 was the final United States Army operation against Apaches who were raiding and not living in a reservation. It began in April after Apache raiders killed three white American settlers in the Arizona Territory. The Apaches were pursued by the army, which caught up with them in the Four Corners region of Arizona, New Mexico, Sonora and Chihuahua. There were only two important encounters during the campaign and, because both of them occurred in the remote Four Corners region, it is unknown if they took place on American or Mexican soil.

Massai was a member of the Mimbres/Mimbreños local group of the Chihenne band of the Chiricahua Apache. He was a warrior who was captured but escaped from a train that was sending the scouts and renegades to Florida to be held with Geronimo and Chihuahua.
