As is well known, Admiral Sims, with the consent of the United States Navy Department, placed all vessels which were dispatched to British waters under the British flag officers in whose Command they were working. This step, which at once produced unity of command, is typical of the manner in which the two navies, under the guidance of their senior officers, worked together throughout the war. The destroyers operating from Queenstown came under Admiral Sir Lewis Bayly; Captain Pringle, the senior United States officer on the spot, whose services were ever of the utmost value, was appointed as Chief of the Staff to Sir Lewis Bayly, whilst on the occasion of Sir Lewis Bayly, at my urgent suggestion, consenting to take a few days' leave in the summer of 1917, Admiral Sims, at our request, took his place at Queenstown, hoisting his flag in command of the British and United States naval forces. The relations between the officers and men of the two navies in this Command were of the happiest possible nature, and form one of the pleasantest episodes of the co-operation between the two nations. The United States officers and men very quickly realized the strong personality of the Commander-in-Chief at Queenstown, and became imbued with the same feelings of great respect and admiration for him as were held by British officers and men. Also he made the officers feel that Admiralty House, Queenstown, was their home when in port, and saw that everything possible was done for the comfort of the men. The very high standard of duty set by Sir Lewis, and very fully sustained by him, was cheerfully and willingly followed by the United States force, the personnel of which earned his warmest admiration. I think it will be agreed in years to come that the comradeship between the two navies, first initiated in the Queenstown Command, went very far towards cementing the bonds of union between the two great English-speaking nations. This was the first step in co-operation. The next was taken when the United States Navy Department, as the result of a request made by us to Admiral Sims, sent to Gibraltar a detachment of three light cruisers and a number of revenue cutters as patrol and escort vessels, placing the whole force under the British senior naval officer at Gibraltar, Rear-Admiral Heathcote Grant. Here again the relations between the two navies were of the happiest nature. Finally, later in the year, I discussed with Admiral Sims the desirability of a small force of United States battleships being sent to reinforce the Grand Fleet.
