Sailor, what of the debt we owe you? Day or night is the peril more? Who so dull that he fails to know you, Sleepless guard of our island shore? Safe the corn to the farmyard taken; Grain ships safe upon all the seas; Homes in peace and a faith unshaken— Sailor, what do we owe for these? _The late Viscount Stuart._ No picture of the war work of the British Navy could be complete without some account of its officers and men. From what has already been said, the nature of the qualities demanded of them will have been realised. In the general direction of the Navy by the Admiralty there have been required calm reflection, profound insight, strategic imagination, sound and swift judgment as to the full use and the yet ill-understood limitations of sea-power, an abundant spring of action, and the unflinching resolution to give effect to the utmost to the striking and controlling force of the naval arm. In the Commander-in-Chief of the Grand Fleet there was needed the high ability to administer and exercise the command, to inspire officers and men of every rank and rating in the Fleet with zeal, efficiency, and devotion, as well as sleepless vigilance in the long waiting for the enemy, and instant readiness for action at all times. The Commander-in-Chief does not work alone. He has a staff who collaborate in these duties and give effect to his plans; and admirals secondary in command, who have no light task in directing the work and operations of the larger elements of the Fleet. Sir John Jellicoe, who was appointed to the Grand Fleet at the beginning of the war, was a master of the high attainments required for his office, and it was he who created the base of his operations, organised all the agencies of his command, and exercised that command with consummate ability. The instrument he had shaped and handled so capably fell to the charge of Sir David Beatty, a most gallant officer, eminently fitted to use it, whose temperament is the very spirit of action, and yet who forms his plans in the mould of cool reflection. Happily for the British Navy, the fire of action is mingled in its officers with the ice of thought. They know when to strike, and when they strike they strike hard.
