The Battle of Apache Pass was fought in 1862 at Apache Pass, Arizona, in the United States, between Apache warriors and the Union volunteers of the California Column as it marched from California to capture Confederate Arizona and to reinforce New Mexico's Union army. It was one of the largest battles between the Americans and the Chiricahua during the Apache Wars.
