Camp Sherman

Camp Sherman was a World War I era United States Army encampment established in 1917 near the San Jacinto Mountains and the San Bernardino Mountains in Southern California. The site functioned as a mobilization and training point for units destined for the American Expeditionary Forces in Europe during the First World War and was associated with regional military infrastructure such as the Presidio of San Francisco and the Camp Kearny mobilization network. Its short period of operation intersected with national mobilization efforts overseen by the War Department and national figures including General John J. Pershing.

History

Camp Sherman was created amid the rapid expansion of the United States Army following the entry of the United States into the First World War in 1917. The establishment linked to federal mobilization policies under the Selective Service Act of 1917 and the logistical planning of the War Department and the General Staff. Troop formations processed at the camp included National Guard units drawn from the California National Guard, elements previously attached to depots such as Fort MacArthur and staging areas like Camp Kearny. The camp’s operational timeline corresponded with major wartime events including the Second Battle of the Marne and the American buildup preceding the Meuse-Argonne Offensive, after which many temporary stations were decommissioned.

Location and Facilities

Situated in a high-desert and chaparral environment near Idyllwild–Pine Cove and the Lake Hemet area, the camp occupied land accessible via rail lines connected to the Southern Pacific Railroad and regional highways that linked to Los Angeles and San Diego. Facilities included wooden barracks, mess halls, a parade ground, rudimentary field hospitals modeled on Walter Reed General Hospital practices, and firing ranges designed in accordance with standards used at posts like Fort Ord. Support infrastructure relied on nearby municipal services in Riverside, California and temporary waterworks similar to projects undertaken by the United States Army Corps of Engineers. The site’s layout reflected contemporary army camp design influenced by logistics doctrines promulgated in the War Department General Orders.

Military Use and Training

At Camp Sherman, recruits underwent basic infantry training, marksmanship instruction on ranges patterned after those at Sierra Army Depot, and field maneuvers consistent with training manuals from the United States Army Training and Doctrine Command antecedents. Units cycled through unit cohesion exercises, gas mask drills informed by lessons from the Battle of Ypres and the use of chemical agents, and mobilization drills paralleling procedures at Camp Lewis and Camp Funston. Command and administrative oversight connected with divisional headquarters that had links to theaters of operation in Western Front logistics. The camp also served as a staging area for artillery detachments and engineer contingents that later supported operations alongside the American Expeditionary Forces.

Post-military Development and Current Status

Following the Armistice of 11 November 1918 and the demobilization programs spearheaded by the War Department, Camp Sherman was rapidly decommissioned and many structures were dismantled or repurposed. Land parcels were sold or returned to private and municipal ownership, echoing redevelopment patterns seen at former installations such as Camp Kearny and Camp Lewis. Over ensuing decades the area experienced land-use changes tied to regional growth driven by Southern California expansion, real estate developments influenced by proximity to Palm Springs and Riverside County population centers, and conservation efforts involving entities like the United States Forest Service. Presently, vestiges of the camp are limited to landscape footprints and occasional archaeological surveys coordinated with agencies such as the California Office of Historic Preservation.

Environmental and Cultural Impact

The establishment and dismantling of Camp Sherman affected local ecosystems in the Peninsular Ranges with impacts on chaparral, oak woodlands, and riparian zones near San Jacinto River tributaries; ecological consequences paralleled those documented around other temporary World War I camps examined by the United States Forest Service and the National Park Service. Culturally, the camp’s presence influenced regional demographics by accelerating infrastructure upgrades that later supported communities in Riverside County and San Bernardino County and intersected with Native American histories of the Cahuilla people and settler communities established during the California Gold Rush aftermath. Commemorative interest has involved local historical societies, county archives, and academic programs at institutions such as the University of California, Riverside and the California State University, San Bernardino which have investigated wartime mobilization, material culture, and landscape transformation tied to Camp Sherman.
