Had this indeed been the result, it is difficult to calculate the profound influence it must have had upon the course of the war, for within a year of the Battle of Jutland over five and a half million tons of shipping were destroyed and throughout that year a very high percentage of British shipbuilding capacity had necessarily to be devoted to purely military purposes. The continued existence of the German Fleet made it impossible to curtail, made it indeed obligatory to increase and accelerate, the building of war ships of all sizes. The effect of this on the capacity to build merchant ships was felt immediately. In pre-war days the shipyards of Great Britain had turned out over a million and a quarter tons of merchant shipping and a quarter of a million tons of naval shipping. The same yards, had their industry been organized as a national activity, could under the pressure of war undoubtedly have produced two and a half million tons a year. The complete destruction of the German Fleet at Jutland, then, would have made the difference of nearly eight million tons of shipping before another year was out. What would this have meant in the saving of treasure, in man-power, in every other form of military strength to the Allies? But apart from these, there were further military objects of a very striking kind that might well have been within reach. We have just seen, in discussing the North Sea strategy, that the kind of blockade we have maintained over the Germans was a long-range sort, leaving the German fleets an area of, say, 60,000 square miles in which to manœuvre. If there had been no fleet of German battleships something very like the old close blockade could have been maintained. It is well known that it is not mines and submarines that close the Channel and the Sound to the German and British fleets. It is the fact that the operation of clearing these things away must expose the force doing it to battleship action. The converse also holds true. If there were no German battleships the operation of confining the German cruisers, destroyers, as well as the German submarines, within waters of comparatively narrow limits, by mines, nets, &c., might not have been impossible. Certainly the opening of the battle would have been comparatively simple. There are many kinds of operations in which it would be folly to risk a battle-fleet so long as the enemy’s battle-fleet was in being. But with no hostile enemy fleet in existence a whole vista of new possibilities is opened up to naval and amphibious force. It is unnecessary to enumerate them. We may take it, then, as axiomatic that, if any chance of bringing the German Fleet to action was offered, it was the first business of the British Navy, and on purely military grounds, no less than those of economic and moral advantage, to force it to decisive action, and that very heavy losses indeed would be justified by complete success.
