Steps were taken to start a school for training young wireless operators at Scapa, first on board each ship, and, later, in a specially fitted merchant ship. The want of wireless operators had been most seriously felt since the War began. In addition to the needs of new warships of all classes in this respect, the requirements for merchant ships, trawlers and other patrol craft were immense and could not be met. In this branch of instruction Lieut.-Commander R. L. Nicholson, the Fleet wireless officer on my staff, carried out invaluable work in organising and starting the school. The training of young ratings in visual signal duties was also taken in hand vigorously under Commander A. E. Wood and the signal officers of the Fleet. The Grand Fleet became, in effect, a great school for turning out trained personnel for the Navy as a whole, whilst still keeping watch over the High Sea Fleet, and controlling the North Sea and its northern exit, thus carrying out its rôle as the centre and pivot of the whole naval side of the War.
Early in 1915 the subject of the instruction and education of the midshipmen also exercised my attention. On mobilisation all the cadets had been removed from Dartmouth and sent to sea, with their training, of course, very incomplete. During the first months of the War, when the ships were either at sea or, if in harbour, were coaling, it was impossible to give these young officers any regular instruction, and, whilst they were learning much that would be invaluable to them in the future, it was evidently highly desirable that their systematic education should be continued as far as was possible during a war.
Steps were accordingly taken in this direction. The first essential was to obtain naval instructors for the ships carrying midshipmen. The policy of the Admiralty, for some years before the War, had been to reduce gradually the number of naval instructors afloat, the idea being that the training at the Colleges and on board the training cruisers rendered the presence of instructors at sea unnecessary. I never held this view personally, but, in any case, it was clear that, as the cadets had gone to sea with less than half their course completed, further instruction at sea was necessary. The specialist officers afloat could not undertake this work under war conditions and strong representations were, therefore, made to the Admiralty on the subject. Eventually a number of gentlemen were entered specially for this instructional work and, after a short course of training in navigation at Greenwich, were sent to the Fleet, where their work proved to be of great value to the rising generation of officers.
The blockade was becoming daily more effective, although the blockading cruisers worked at so great a distance from the German coast. The only interference ever attempted by the enemy was by submarine attack or by mines, and during the year 1915 no great success was achieved by them in this respect when the conditions are considered. The regular blockading squadron, the 10th Cruiser Squadron, was assisted in its work by the sweeps of our cruisers and light cruisers, accompanied occasionally by the Battle Fleet. In addition to the discharge of these duties, the Battle Fleet engaged in periodical cruises, during which battle exercises were carried out for the purpose of maintaining efficiency in the handling of the ships and squadrons and of giving the fresh officers, who were frequently joining the Fleet, to replace others required for the new ships, experience in the work of the Grand Fleet under the novel war conditions.
Pursuant to this general policy, the Dreadnought Battle Fleet remained in harbour until January 10th, and then left for a cruise to the westward of the Orkneys and Shetlands. Gunnery practices were carried out by day and at night, as well as battle exercises, and the Fleet returned to Scapa during the day and the night of the 13th. The 3rd Battle Squadron left Rosyth on the 12th for a cruise in the North Sea, and on the night of the 13th–14th passed to the westward of the Orkneys for gunnery practice, returning to Rosyth on the 15th.
Other events of interest during the first fortnight of January were the return of the Princess Royal from North American waters on the 1st; a short cruise in the centre of the North Sea by the 1st Battle Cruiser Squadron and the 1st Light Cruiser Squadron between the 3rd and the 5th, and by the 3rd Cruiser Squadron between the 6th and the 8th; a cruise by the 1st Cruiser Squadron to the westward of the Orkneys between the 4th and 6th, and by the 6th Cruiser Squadron between the 6th and the 9th, and the 10th and 14th. On January 4th the King George V. completed the work of retubing her condenser.
On the 9th all ships at Scapa raised steam ready for leaving, in consequence of a report of a submarine being sighted in Hoy Sound, and available destroyers and trawlers were sent to patrol in the vicinity of the Hoy anti-submarine Fleet obstructions until the Battle Fleet left harbour on the 10th.
Gales were experienced at Scapa on the 1st, 13th, 16th and 19th of January.
On January 15th the 2nd Battle Cruiser Squadron was reconstituted, under Vice-Admiral Sir A. G. W. Moore, K.C.B., whose flag was transferred from the Leviathan, of the 1st Cruiser Squadron, to the New Zealand; the 2nd Battle Cruiser Squadron then comprised the New Zealand, Indomitable and Invincible (the last not having yet arrived). Rear-Admiral Sir Robert Arbuthnot, Bart., took command of the 1st Cruiser Squadron in place of Sir Gordon Moore, flying his flag in the Defence, which took the place of the Leviathan; the latter vessel was transferred to the 6th Cruiser Squadron. Rear-Admiral A. C. Leveson, C.B., relieved Sir Robert Arbuthnot as Rear-Admiral in the 2nd Battle Squadron, flying his flag in the Orion.
On the 17th the 1st and 2nd Battle Cruiser Squadrons and 1st Light Cruiser Squadron left Rosyth for a cruise in the centre and southern portions of the North Sea, and on the 19th, at dawn, arrived in position Lat. 55 N., Long. 5.30 E. to support Commodore Tyrwhitt in carrying out a reconnaissance in Heligoland Bight. Nothing was sighted beyond an airship and a sea-plane, and the force was ordered to return to its bases and arrived during the night of the 20th–21st.
