## History

Department of the Pacific was created January 15, 1861, during the American Civil War. The District of Southern California was established on September 25, 1861.
The district was composed of San Luis Obispo County, Tulare County, Santa Barbara County, Los Angeles County, San Bernardino County, and San Diego County. Tulare County at the time was composed of additional territory now belonging to Kern County, to Inyo County, Kings County and a small part of southeastern Fresno County. Santa Barbara County included what is now Ventura County, Los Angeles County included what is now Orange County and parts of Kern and Inyo County. San Bernardino County contained parts of Inyo and Riverside Counties. San Diego County included most of Riverside County, and Imperial County.
Its first headquarters was located at Camp Latham, located west of Los Angeles. The headquarters was later moved to Drum Barracks. On July 27, 1865, the Military Division of the Pacific was created under Major General Henry W. Halleck, replacing the Department of the Pacific. The department consisted of the Department of the Columbia and the expanded Department of California absorbing the District of Southern California that now consisted of the States of California and Nevada and the Territory of New Mexico and Territory of Arizona.
