The second requisite for victory, that is, for winning a battle against a hostile fleet, is tactical superiority, or, as Nelson put it: "The skill of our admirals and the activity and spirit of our officers and seamen." The only way to obtain this is through the perpetual practice of the admirals commanding fleets. An admiral, in order to make himself a first-rate tactician, must not merely have deeply studied and pondered the subject, but must spend as much time as possible in exercising, as a whole, the fleet which he commands, in order not only by experimental manoeuvres thoroughly to satisfy himself as to the formation and mode of attack which will be best suited to any conceivable circumstance in which he may find himself, but also to inculcate his ideas into his subordinates; to inspire them with his own knowledge, and to give them that training in working together which, in all those kinds of activities which require large numbers of men to work together, whether on the cricket field, at football, in an army, or in a navy, constitutes the advantage of a practised over a scratch team.
If the practice is to make the fleet ready for war, it must be carried out with the fleet in its war composition. All the different elements, battleships, cruisers, torpedo craft, and the rest, must be fully represented, otherwise the admiral would be practising in peace with a different instrument from that with which he would need to operate in war.
The importance of this perpetual training ought to be self-evident. It may be well to remind the reader that it has also been historically proved. The great advantage which the British possessed over the French navy in the Wars of the Revolution and the Empire was that the British fleets were always at sea, whereas the French fleets, for years blockaded in their ports, were deficient in that practice which, in the naval as in all other professions, makes perfect. One of the complaints against the present Board of Admiralty is that it has not encouraged the training and exercise of fleets as complete units.
Another point, in regard to which the recent practice of the Admiralty is regarded with very grave doubts, not only by many naval officers, but also by many of those who, without being naval officers, take a serious interest in the navy, is that of naval construction. For several years the Admiralty neglected to build torpedo craft of the quality and in the quantity necessary for the most probable contingencies of war, while, at the same time, large sums of money were spent in building armoured cruisers, vessels of a fighting power so great that an admiral would hesitate to detach them from his fleet, lest he should be needlessly weakened on the day of battle, yet not strong enough safely to replace the battleships in the fighting line. The result has been that the admirals in command of fleets have for some time been anxiously asking to be better supplied with scouts or vessels of great speed, but not of such fighting power that they could not be spared at a distance from the fleet even on the eve of an action. These two defects in the shipbuilding policy of the Admiralty make it probable that for some years past the navy has not been constructed in accord with any fully thought-out design of operations; in other words, that the great object "victory" has been forgotten by the supreme authority.
The doubt whether victory has been borne in mind is confirmed by what is known of the design of the original Dreadnought. A battleship ought to be constructed for battle, that is, for the purpose of destroying the enemy's fleet, for which purpose it will never be used alone, but in conjunction with a number of ships like itself forming the weapon of an admiral in command. A battleship requires three qualities, in the following order of importance:—
First, offensive power. A fleet exists in order to destroy the enemy, but it has no prospect of performing that function if its power of destruction is less than its enemy's. The chief weapon to-day, as in the past, is artillery. Accordingly the first requisite of a fleet, as regards its material qualities, those produced by the constructor, is the capacity to pour on to the enemy's fleet a heavier rain of projectiles than he can return.
The second quality is the power of movement. The advantage of superior speed in a fleet—for the superior speed of an individual ship is of little importance—is that so long as it is preserved it enables the admiral, within limits, to accept or decline battle according to his own judgment. This is a great strategical advantage. It may in some conditions enable an inferior fleet to postpone an action which might be disastrous until it has effected a junction with another fleet belonging to its own side.
The third quality is that the ships of a fleet should be strong enough to offer to the enemy's projectiles a sufficient resistance to make it improbable that they can be sunk before having inflicted their fair share of damage on the adversary.
There is always a difficulty in combining these qualities in a given ship, because as a ship weighs the quantity of water which she displaces, a ship of any given size has its weight given, and the designer cannot exceed that limit of weight. He must divide it between guns with their ammunition, engines with their coal, and armour. Every ton given to armour diminishes the tonnage possible for guns and engines, and, given a minimum for armour, every extra ton given to engines and coal reduces the possible weight of guns and ammunition. In the Dreadnought a very great effort was made to obtain a considerable extra speed over that of all other battleships. This extra speed was defended on the ground that it would enable a fleet of Dreadnoughts to fight a battle at long range, and with a view to such battle the Dreadnought was provided only with guns of the heaviest calibre and deprived of those guns of medium calibre with which earlier battleships were well provided. The theories thus embodied in the new class of ships were both of them doubtful, and even dangerous. In the first place, it is in the highest degree injurious to the spirit and courage of the crew to have a ship which they know will be at a disadvantage if brought into close proximity with the enemy. Their great object ought to be to get as near to the enemy as possible. The hypothesis that more damage will be done by an armament exclusively of the largest guns is in the opinion of many of the best judges likely to be refuted. There is some reason to believe that a given tonnage, if devoted to guns of medium calibre, would yield a very much greater total damage to an enemy's ship than if devoted to a smaller number of guns of heavy calibre and firing much less rapidly.
There is, moreover, a widespread belief among naval officers of the highest repute, among whom may be named the author of the "Influence of Sea Power upon History," than whom no one has thought more profoundly on the subject of naval war, that it is bad economy to concentrate in a few very large ships the power which might be more conveniently and effectively employed if distributed in a great number of ships of more moderate size.
