A feature of the patrol service of much interest was the manner in which a large number of retired officers, including many of flag rank—­who had reached mature age—­volunteered for service in the yachts and other small craft engaged in the work.  The late Admiral Sir Alfred Paget was one of the first, if not the first, to come forward, and in order to avoid any difficulty in the matter of rank, this fine veteran proposed to sink his Naval status and to accept a commission as captain of the Royal Naval Reserve.  Sir Alfred, in common with many other officers who took up this work, was over sixty, but age did not deter these gallant seamen from facing the hardship and discomfort of service in small craft in the North Sea and elsewhere.  To name all the officers who undertook this duty, or who were in charge of patrol areas, would be impossible, and it may seem invidious to mention names at all; but I cannot forbear to speak of some of those with whom I came most frequently into contact during 1917.  Sir James Startin, K.C.B., who was the life and soul of the patrols and minesweepers working from Granton, was frequently at sea in decoy ships fitted out there, as well as in minesweepers, etc., and together with his son won the Albert Medal for saving life during the war; Admiral J.L.  Marx, C.B., D.S.O., served also in a decoy ship; Admiral John Denison, D.S.O., was in charge first at Falmouth and later at Kingstown; Admiral T.P.  Walker, D.S.O., had his yacht sunk under him; Admiral Sir Charles Dare, K.C.M.G., C.B., won great distinction in command of the patrols, etc., working from Milford Haven; and Rear-Admiral C.H.  Simpson’s Peterhead trawlers, splendidly manned, took a heavy toll of enemy submarines.  A large number of retired Naval officers below the rank of admiral served in minesweepers and patrol craft, and in command of various areas, and their work was of the greatest possible value.  A few of those with whom I came into personal contact during the year 1917 were the late Captain F. Bird, C.M.G., D.S.O., who was most conspicuous in command of the drifters of the Dover Patrol; Captain W. Vansittart Howard, D.S.O., who commanded the Dover Trawler Patrol with such ability; Commander Sir George Armstrong, Bart., who so successfully inspired the minesweeping force working from Havre; and Commander H.F.  Cayley, D.S.O., whose services in the Harwich minesweeping force, working under his brother, Rear-Admiral C.G.  Cayley, were invaluable.

So much for the patrol craft.  The great work carried out by the minesweepers can be best judged by quoting a few figures for 1917, during which year the mine menace attained its maximum intensity, owing to the large increase in the number of German submarine minelayers.

During the year 1916 the average number of mines swept up per month was 178.

Statistics for 1917 show the following numbers of mines swept up per month:
