The site of Fort Breckinridge was reoccupied as Fort Stanford, or Camp Stanford, from 1862 to 1865 by troops of the California Column. When the U.S. Army proper finally reoccupied the site, it was renamed Camp Grant between 1865 and 1872. In 1872, after the Camp Grant Massacre, the United States Army post at old Camp Grant (at the confluence of Aravaipa Creek and the San Pedro River) was relocated to the southwestern slope of Graham Mountain in what is now Graham County. The new fort was strategically placed so as to protect settlers who were constantly harassed by Apache warriors. It played a prominent role in the Apache Wars of the 1880s.
