On May 17th a second American destroyer flotilla of six ships arrived at Queenstown. From that date until July 5th a new division put in nearly every week. The six destroyers which escorted our first troopships from America to France were promptly assigned to duty with our forces in Irish waters. Meanwhile other ships were added. On May 22nd the _Melville_, the "Mother Ship" of the destroyers, arrived and became the flagship of all the American vessels which were stationed at Queenstown. This repair and supply ship practically took the place of a dockyard, so far as our destroyer forces were concerned. Queenstown had been almost abandoned as a navy yard many years before the European War and its facilities for the repair of warships were consequently very inadequate. The _Melville_ relieved the British authorities of many responsibilities of this kind. She was able to do three-quarters of all this work, except major repairs and those which required docking. Her resources for repairing destroyers, and for providing for the wants and comforts of our men, aroused much admiration in British naval circles. The rapidity with which our forces settled down to work, and the seamanly skill which they manifested from the very beginning, likewise made the most favourable impression. By July 5th we had thirty-four destroyers at Queenstown--a force that remained practically at that strength until November. In 1918 much of the work of patrolling the seas and of convoying ships to the west and south of Ireland--the area which, in many ways, was the most important field of submarine warfare--fell upon these American ships. The officers and crews began this work with such zest that by June 1st I was justified in making the following statement to the Navy Department: "It is gratifying to be able to report that the operations of our forces in these waters have proved not only very satisfactory, but also of marked value to the Allies in overcoming the submarine menace. The equipment and construction of our ships have proved adequate and sufficient, and the personnel has shown an unusually high degree of enthusiasm and ability to cope with the situation presented."
