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. One other factor exercised a cramping effect upon our naval strategy throughout the War, namely, the bombardment of our undefended towns on the East Coast. Such bombardments were of no immediate military value to the enemy, but, in spite of the fact that the majority of the Press, and the public, realised that the Navy should not be led into false strategy because of these bombardments, it was difficult for the Fleet to ignore them, and I have no doubt that the Germans relied upon this fact. Whilst the Fleet was based at Scapa Flow, it was quite impossible to ensure that the enemy would be brought to action after such an operation, since to attain this end it would have been necessary for the Fleet, or a portion of it, to be constantly cruising in the southern portion of the North Sea. This was not practicable, even had it been desirable, because of the impossibility of keeping destroyers with the heavier ships, and in any case it was false strategy to divide the Battle Fleet, as such a course might well have resulted in disaster. The usual course adopted was to base the Battle Cruiser Fleet on Rosyth, and for that Fleet to cruise from that neighbourhood. The speed of the battle cruisers enabled them to get away from a decidedly superior enemy force of battleships if encountered, but there was always some risk in this case of a ship being disabled; the flag officer in command would then have been faced with the unpleasant alternative of abandoning her or of risking his whole force to cover her retreat.
