Charles Warren Foster (1830 – 1904) was an American soldier and military officer. He first served as an enlisted engineer and NCO in the United States Army during the Mexican–American War and then as a commissioned officer in the American Civil War. In the latter he notably headed the Bureau of Colored Troops, managing the recruitment and organization of African-American units for the Union Army. In 1865 he also received a Regular Army commission, being made captain in the Quartermaster Corps and receiving regular brevets to major, lieutenant colonel and colonel for his war service. He continued to lead the bureau during the early Reconstruction era, until it was disestablished in October 1867, at the same time mustering out of the USV. Foster remained in the army, now with his regular commission as captain and quartermaster, and in 1868 went with an expedition to Alaska. In the following years he served on various posts in the departments of California, Arizona, Dakota, Utah and eventually back in the East, being promoted to major in 1883. He stayed on duty until 1891, when he retired after 40 years of service.
Fort Whipple served as a tactical base for detachments of several regiments involved in the American Indian Wars between 1864 and 1886. Fort Whipple became headquarters of the Military Department of Arizona from 1870 to 1886 when Colonel George Crook was assigned to Fort Whipple. Whipple Depot was destroyed by fire in April 1872 and rebuilt by July 1872.

Camp Hualapai, Arizona was a U.S. Army camp established in May 1869, at the close of the Hualapai War, just southeast of Aztec Pass (located on Walnut Creek Road north of Prescott) It was built by Major William R. Price and his men of the 8th U.S. Cavalry; it was first named Camp Devin, but was quickly renamed Camp Toll Gate because it was established along the Hardyville-Prescott Toll Road. Its purpose was to protect the road from Indian attacks. It was renamed once again to Camp Hualpai on August 1, 1870. A small settlement that grew up around the camp became known as Juniper. The camp was abandoned on July 31, 1873, and later transferred to the Department of the Interior.
