Some Principles of Maritime Strategy

by Julian Stafford Corbett

The indecisive campaign which naturally resulted from this lack of strategical grip and concentration of effort came to an

end with Tromp's partial defeat of Blake off Dungeness on 30th November 1652. Though charged in spite of his protests with a vast convoy, the Dutch admiral had sent it back to Ostend when he found Blake was in the Downs, and then, free from all preoccupation, he had gone to seek out his enemy.

It was the effect which this unexpected blow had upon the strong military insight of the Cromwellian Government that led to those famous reforms which made this winter so memorable a landmark in British naval history. Monk, the most finished professional soldier in the English service, and Deane, another general, were joined in the command with Blake, and with their coming was breathed into the sea service the high military spirit of the New Model Army. To that winter we owe not only the Articles of War, which made discipline possible, and the first attempt to formulate Fighting Instructions, in which a regular tactical system was conceived, but also two other conceptions that go to make up the modern idea of naval warfare. One was the conviction that war upon the sea meant operations against the enemy's armed fleets in order to destroy his power of naval resistance as distinguished from operations by way of reprisal against his trade; and the other, that such warfare required for its

effective use a fleet of State-owned ships specialised for war, with as little assistance as possible from private-owned ships. It was not unnatural that all four ideas should have taken shape together, so closely are they related. The end connotes the means. Discipline, fleet tactics, and a navy of warships were indispensable for making war in the modern sense of the term.

The results were seen in the three great actions of the following spring, the first under the three Generals, and the other two under Monk alone. In the last, he carried the new ideas so far as to forbid taking possession of disabled vessels, that nothing might check the work of destruction. All were to be sunk with as much tenderness for human life as destruction would permit. In like manner the second war was characterised by three great naval actions, one of which, after Monk had resumed command, lasted no less than four days. The new doctrine was indeed carried to exaggeration. So entirely was naval thought centred on the action of the battle-fleets, that no provision was made for an adequate exercise of control. In our own case at least, massing for offensive action was pressed so far that no thought was given to sustaining it by reliefs. Consequently our offensive power suffered periods of exhaustion when the fleet had to return to its base, and the Dutch were left sufficient freedom not only to secure their own trade, but to strike severely at ours. Their counterstrokes culminated in the famous attack upon Sheerness and Chatham. That such an opportunity was allowed them can be traced directly to an exaggeration of the new doctrine. In the belief of the British Government the "St.

James's Fight"—the last of the three actions—had settled the question of command. Negotiations for peace were opened, and they were content to reap the fruit of the great battles in preying on Dutch trade. Having done its work, as was believed, the bulk of the battle-fleet for financial reasons was laid up, and the Dutch seized the opportunity to demonstrate the limitations of the abused doctrine. The lesson is one we have never forgotten, but its value is half lost if we attribute the disaster to lack of grasp of the battle-fleet doctrine rather than to an exaggeration of its possibilities.

The truth is, that we had not obtained a victory sufficiently decisive to destroy the enemy's fleet. The most valuable lesson of the war was that such victories required working for, and particularly in cases where the belligerents face each other from either side of a narrow sea. In such conditions it was proved that owing to the facility of retreat and the restricted possibilities of pursuit a complete decision is not to be looked for without very special strategical preparation. The new doctrine in fact gave that new direction to strategy which has been already referred to. It was no longer a question of whether to make the enemy's trade or his fleet the primary objective, but of how to get contact with his fleet in such a way as to lead to decisive action. Merely to seek him out on his own coasts was to ensure that no decisive action would take place. Measures had to be taken to force him to sea away from his own bases. The favourite device was to substitute organised strategical operations against his trade in place of the old sporadic attacks; that is, the fleet took a position calculated to stop his trade altogether, not on his own coasts, but far to sea in the main fairway. The operations failed for lack of provision for enabling the fleet by systematic relief to retain its position, but nevertheless it was

the germ of the system which afterwards, under riper organisation, was to prove so effective, and to produce such actions as the "Glorious First of June."

In the third war, after this device had failed again and again, a new one was tried. It was Charles the Second's own conception. His idea was to use the threat of a military expedition. Some 15,000 men in transports were brought to Yarmouth in the hope that the Dutch would come out to bar their passage across the open North Sea, and would thus permit our fleet to cut in behind them. There was, however, no proper coordination of the two forces, and the project failed.

This method of securing a decision was not lost sight of; Anson tried to use it in the Seven Years' War. For two years every attempt to seek out the enemy's fleet had led to nothing but the exhaustion of our own. But when Pitt began his raids on the French coast, Anson, who had little faith in their value for military purposes, thought he saw in them definite naval possibilities. Accordingly when, in 1758, he was placed in command of the Channel Fleet to cover the expedition against St. Malo, he raised the blockade of Brest, and took up a position near the Isle of Batz between the enemy's main fleet and the army's line of passage. The Brest fleet, however, was in no condition to move, and again there was no result. It was not till 1805 that there was any clear case of the device succeeding, and then it was not used deliberately. It was a joint Anglo-Russian expedition in the Mediterranean that forced from Napoleon his reckless order for Villeneuve to put to sea from Cadiz, and so solved the problem out of which Nelson had seen no issue. Lissa may be taken as an analogous
