But while battles upon land have become much less decisive than in the simpler days of small armies and feeble weapons, fighting upon the sea has become much quicker, much more crushingly final, in its effects and results than in the days of our grandfathers. Speed and gun power are now everything. The faster and more powerful fleet—more powerful in its capacity for dealing accurate and destructive blows—can annihilate its enemy completely within the brief hours of a single day. The more powerful and faster his ships the less will the victor himself suffer. Only under one condition can a defeated fleet escape annihilation, and that is when the lack of light or of sea room snatches from the victor a final decision. If an enemy can get away under shelter of his shore fortifications, or within the protection of his minefields, he can defy pursuit; but if there be ample room and daylight Speed and Power wielded by men such as ours, will prevail with absolute mathematical certainty—the losers will be sunk, the victors will, by comparison, be little damaged. Every considerable engagement during the war has added convincing proof to the conclusions which our Navy drew from the decisive battle in the Sea of Tsushima between the Japanese and the Russians, and the not less decisive action upon a smaller scale in which the Americans destroyed the Spanish squadron off Santiago, Cuba. In both cases the losers were destroyed while the victors suffered little hurt. These outstanding lessons were not lost upon the Royal Navy, its officers had themselves seen both fights, and so in its silent way the Navy pressed upon its course always seeking after more speed, more gun power, and above all more numbers. “Only numbers can annihilate,” said Napoleon, and what the Emperor declared to be true of land fighting is the more true of fighting by sea. Only numbers can annihilate.
