Stevedore operations were established by the United States Army to provide movement of supplies through ports in support of the American Expeditionary Forces during World War I. The first American stevedores in France were civilians. Stevedores were originally organized into regiments, and were among the first troops sent to France. Three regiments and two separate battalions were deployed, and were later reorganized into separate battalions and transferred from the Army Service Corps to the Transportation Corps. The battalions were inactivated in France and the troops were assigned to companies without a branch affiliation for their return to the U.S.
