Once the Confederates were driven from New Mexico, Carson's commander Major James Henry Carleton, turned his attention to the Native Americans. The historian Edwin Sabin writes that this officer had a "psychopathic hatred of the Apaches". Carleton led his forces deep into the Mescalero Apache territory. The Mescaleros were tired of fighting, and put themselves under Carson's protection. Carleton put these Apaches on a remote and lonely reservation east on the Pecos River.
