The dispositions that have been described took account naturally of two other very important factors.
The first was the transport of our Expeditionary Force to France. It was highly probable that the enemy would endeavour to interfere with this movement, and in the early days of the War it would not have been a difficult matter for him to cause us some loss. His failure to make at least some attempt in this direction showed a lack of enterprise which surprised me, as I think it surprised most naval officers.
The conditions for him were distinctly favourable. Our main Fleet was based, as he must have been aware, far away to the northward, and if he had timed an attack on the cross-Channel traffic for a period during which he reckoned that the Grand Fleet, or at least the destroyers, were returning to the base to fuel, he would have stood a good chance of making the attack and returning to his base before that Fleet could intervene. Consequently, he would only have had to deal with the comparatively light forces based in southern waters. On the other hand, if our Fleet arrived on the scene without destroyers, the Germans would have possessed no mean advantage.
The enemy was provided with a large number of modern destroyers, and some of them would have been well expended over a Channel dash, which would in all probability have met with some success. During the transport of the Expeditionary Force the heavy ships of the Grand Fleet kept the sea as far as possible in order to cover the movement, but the destroyers were constantly returning to the base to fuel.
The second factor which had considerable influence on Fleet dispositions was the possibility of an attempt at a raid or invasion by the enemy. Such a move was not very likely in the earliest days of the War, when the nights were comparatively short and the Expeditionary Force had not left the country. It is also probable that the enemy had few troops to spare for the purpose. But the chances became greater as we denuded the country of men, and the conditions in other respects became more favourable. In October and November, 1914, I held and expressed the opinion that, if raids were attempted, landings would probably be effected in the rivers on the East Coast, the entrances to which were either unprotected or inadequately protected. A beach landing on our East Coast can only be carried out in fine weather, and the chances of encountering favourable conditions on arrival off the coast are not great, and I always doubted the attempt being made. In our rivers the opportunities are greater, and are not so dependent on fine weather, and I suggested to the Admiralty that a simple preventive in this case was to place merchant ships in position ready to be sunk across the channels (which are narrow and shallow), the ships being fitted with explosive charges below ready to blow out the bottoms in case of necessity. I mentioned the names of certain retired naval officers who, I felt certain, would make all the necessary preparations in a very few days. I believe that my proposals were carried out.
The danger of raids, however, and the consequent responsibility thrown upon the Admiralty for their prevention, during a period when we had very little military force in the country, led to a division of the Fleet by Admiralty direction, which, however necessary, had certain disadvantages from a strategic point of view.
The 3rd Battle Squadron, consisting of eight ships of the “King Edward VII.” class, and the 3rd Cruiser Squadron of four ships of the “County” class, were ordered to be based on Rosyth, together with destroyers for screening purposes. The eventuality that had then to be faced was that of the remainder of the Grand Fleet having to engage the High Sea Fleet, since concentration with the 3rd Battle Squadron could probably not be effected without the risk of losing the opportunity of engaging.
At this time the battle cruisers Princess Royal, Invincible, and Inflexible were in the Atlantic operating against Von Spee’s squadron; and the Australia, Indomitable had not joined the Grand Fleet. The Tiger was not yet ready, so that at times our battle cruiser force consisted of only three ships, the Lion, Queen Mary, and New Zealand.
Throughout the War the responsibility of the Fleet for the prevention of raids or invasion was a factor which had a considerable influence on naval strategy.
If the Fleet, with destroyers, carried out a sweep in the North Sea, or if it was at sea for a cruise having exercises for its main object, there was bound to be present in the mind of the Commander-in-Chief the chance that he might be required suddenly to move south to engage the High Sea Fleet which had put to sea to cover a landing. If his destroyers were short of fuel at such a moment very serious consequences might ensue, and therefore all cruiser sweeps or other operations had to be curtailed to prevent such a situation arising.
