The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting the Army Distinguished Service Medal to Major (Infantry) Stephen Jones Chamberlin, United States Army, for exceptionally meritorious and distinguished services to the Government of the United States, in a duty of great responsibility during World War I. As Acting Dispatch Officer at Port of Embarkation, Hoboken, New Jersey, from 15 November 1917 to 6 September 1918, Major Chamberlin displayed marked ability in handling the movements of troops through the port, assigning units and detachments to camps, convoys, and ships, and by foresight, thorough organization, and hard work arranged for the smooth working of troop movements, prevented congestion at the camps and piers, thus enabling the transports to sail at the appointed time with the appropriate number of troops.
