Most of the remainder were transported in ships under British control. To guard against submarine attack, American transports making the trip to Europe were, as far as practicable, gathered into groups and escorted through the danger zone by destroyers and other armed vessels. This method of combat- ing the submarine menace was most suc- cessful and the results obtained were re- markable. Not a single vessel of the Cruiser and Transport Force was lost on the eastward voyage, although three Stern of Des troyer Showing 4-Inch Gun and ships returning to the United States were Depth Bombs Used Agains t Submarines sunk out of a total of five torpedoed. Nearly all the troops who crossed the Atlantic in American and French ships landed at French ports, while those going in other vessels landed in England. This necessitated the establishment of a small transport force of American ships at Southampton, the chief port used for reembarkation to France, in order to aug- ment the British cross-channel service. As the number of troops overseas in- creased, the task of supplying them be- came more difficult. This problem was met by the formation of the Naval Over- seas Transportation Service, which was a force distinct from the troop transport organization. It developed into a fleet of more than 400 vessels, manned by ap- proximately 4,500 officers and 29,000 men. To form this great organization it was Explosion of a 300-Pound Depth Bomb Dropped necessary to take vessels from every by a United States Destroyer, May 18, 19l 8 available source, and included in it were ships taken over from the Shipping Board, new tonnage resulting from the intensive building program of the Emer- gency Fleet Corporation, and a number of ships which were brought from the Great Lakes under considerable difficul- ties. The convoy system was also used insofar as possible in the operation of this fleet, and only seven vessels were lost by enemy action. This was considered an exceptionally fine record. As soon as the safety of the transports and supply ships had been reasonably assured, aggressive steps were taken against enemy submarines.
