"Let me say to you on behalf of the British people what a debt of gratitude we owe to your navy for its co-operation with us. There is no finer spectacle to be seen at present than that complete and cordial co-operation which is existing between your fleet and ours. They work as one. I always think to myself and hope that the co-operation of our fleets, of our navies, is the harbinger of what is to come in the future when the war is over, of that which will still continue then. Magnificent is their work, and I glory always in the thought that an American admiral has taken charge of the British Fleet and the British policy, and that when the plans are formed for an attack that American admiral is given the place of honor in our fleet, because we feel that it is his due at this moment." And finally, there is the testimony of Admiral Sir Rosslyn Wemyss, first sea lord of the British, concerning our effective aid, testimony, by the way, which enlightens us to some extent upon British and American methods of co-operation. "On the broad lines of strategic policy," he said, "complete unanimity exists. Admiral Benson and Admiral Mayo have both visited us and studied our naval plans. No officers could have exhibited keener appreciation of the naval situation. I find it difficult to express the gratitude of the British service to these officers and to Admiral Sims for the support they have given us. I am not exaggerating, or camouflaging, to borrow a word of the moment. Our relations could not be more cordial. The day-to-day procedure is of the simplest. Every morning I hold conference with the principal officers of the naval staff, and Admiral Sims is present as the representative of the United States Fleet, joining freely in the discussion of the various subjects which arise. I need not add that I keenly appreciate his help. At sea the same spirit of cordial co-operation exists--extremely cordial. I should like to say we have, fortunately, a common language and common traditions, which have done much to assist us in working together. "The American officers and men are first-rate. It is impossible to pay too high a tribute to the manner in which they settled down to this job of submarine hunting, and to the intelligence, resource, and courage which they have exhibited. They came on the scene at the opportune moment. Our men had been in the mill for many weary months. Possibly the American people, so far removed from the main theatre of the war, can hardly appreciate what it meant when these American officers and men crossed the Atlantic. They have been splendid, simply splendid. I have seen a number of the destroyers and conversed with a large number of officers. I also have had many reports and am not speaking of the aid the United States has rendered without full knowledge.
