Camp Stoneman

Camp Stoneman was a United States Army staging area and embarkation camp established during World War II near Pittsburg, California, intended to process and transport troops to the Pacific Theater, the China Burma India Theater, and later to support operations in Korean War logistics. The facility served as a nexus between rail lines, port facilities at San Francisco Bay and military transportation networks including United States Coast Guard operations and Army Transportation Corps units. After the war it was used in demobilization, veterans' return processing, and Cold War planning involving Department of Defense components and Veterans Administration resources.

History

Camp Stoneman was activated in 1942 following the United States' entry into World War II after Attack on Pearl Harbor. Construction involved coordination with the War Department, United States Army Corps of Engineers, and regional authorities including Alameda County and Contra Costa County. The camp was named in honor of George Stoneman Jr. and was part of a broader expansion of staging areas including Fort Ord, Fort Lewis, Fort Benning, and Camp Pendleton. During its wartime peak the camp interfaced with the Office of Defense Transportation, the War Shipping Administration, and United Service Organizations for troop morale and transit services. Postwar demobilization saw ties to the GI Bill implementation, Selective Service System adjustments, and the repatriation operations coordinated with American Red Cross and United Nations Relief and Rehabilitation Administration processes.

Location and Facilities

Located near Pittsburg, California on the eastern shore of San Francisco Bay, the camp utilized rail connections to the Southern Pacific Railroad and shipping access via the Port of San Francisco and Oakland Harbor. Facilities included barracks, mess halls, motor pools, supply depots, and staging patios adjacent to warehouses used by the Army Service Forces and Quartermaster Corps. Medical support came from units linked to Walter Reed Army Medical Center protocols and the camp coordinated with nearby installations such as Naval Supply Depot Oakland, Bay Area civilian hospitals, and Treasure Island (San Francisco). Administrative oversight involved offices that worked with the Office of the Provost Marshal General and regional commanders reporting to the Western Defense Command and Army Ground Forces.

Role in Military Operations

As a primary embarkation camp, Camp Stoneman processed divisions, regiments, and individual replacements destined for operations in the Pacific War, including campaigns like Guadalcanal Campaign, Philippine Campaign (1944–45), and Battle of Okinawa. The camp coordinated troop movements with the Army Transportation Corps and convoy sailings organized by the Military Sea Transportation Service and tugs serving the Military Sealift Command precursors. Intelligence and security screening linked to the Counterintelligence Corps and the Military Intelligence Division ensured unit readiness for overseas deployment. During the Korean War, the camp resumed expanded activity supporting deployments to United Nations Command operations on the Korean Peninsula, working with Pacific Fleet logistical schedules and Seventh Fleet embarkation coordination.

Notable Units and Personnel

Units processed or staged at Camp Stoneman included elements of the 25th Infantry Division, 32nd Infantry Division, 91st Infantry Division, 7th Infantry Division, 81st Infantry Division, and numerous Service Command detachments, Quartermaster Corps companies, Signal Corps units, and Medical Corps contingents. High-profile personnel who passed through or inspected the camp included representatives from General Douglas MacArthur's staff, officers from United States Army Forces Pacific, and delegations tied to Commander-in-Chief, Pacific Fleet leadership. The camp also hosted visits from civic and political figures such as members of United States Congress, state governors, and officials from the Office of War Information and the American Red Cross.

Postwar Use and Legacy

After World War II, Camp Stoneman served as a demobilization and redistribution center assisting returning veterans under programs influenced by the Servicemen's Readjustment Act of 1944 (the GI Bill). In the late 1940s and into the Korean War, it was intermittently reactivated to support mobilization and redeployment linked to Department of Defense planning and National Guard federalization. The camp’s physical footprint was gradually repurposed for industrial and municipal uses involving Port of Stockton expansion interests, local Pittsburg redevelopment, and state infrastructure projects with input from California Department of Transportation and State Lands Commission. Commemorations and historical preservation efforts have involved National Park Service advisors, local historical societies, and veterans' organizations such as the American Legion and Veterans of Foreign Wars. The legacy of the camp is reflected in regional military histories, archives held by National Archives and Records Administration, and oral histories collected by universities including University of California, Berkeley and Stanford University.
