 The Marine Corps Logistics Base, presently the second largest employer in the Barstow area, was established as the Marine Corps Depot of Supplies at its present location on December 28, 1942, when the United States Navy turned it over to the Marine Corps as a storage site for supplies and equipment needed for Fleet Marine Forces in the Pacific theater during World War II.By the end of World War II, the base had outgrown its facilities and as a result, 2,000 acres (8 km²) of land, approximately seven miles east of the Nebo Main Base were annexed from the United States Army in October 1946.In 1954, the Commanding General, Marine Corps Depot of Supplies, Roy M. Gulick, moved his flag from San Francisco to Barstow and since then the base has grown in stature, strength and size.
