The great end of a war fleet, however, is not to chase, nor to fly, but to control the seas. Had Cervera escaped our pursuit at Santiago, it would have been only to be again paralyzed at Cienfuegos or at Havana. When speed, not force, is the reliance, destruction may be postponed, but can be escaped only by remaining in port. Let it not, therefore, be inferred, from the possible, though temporary, effect of a “fleet in being,” that speed is the chief of all factors in the battleship. This plausible, superficial notion, too easily accepted in these days of hurry and of unreflecting dependence upon machinery as the all in all, threatens much harm to the future efficiency of the navy. Not speed, but power of offensive action, is the dominant factor in war. The decisive preponderant element of great land forces has ever been the infantry, which, it is needless to say, is also the slowest. The homely summary of the art of war, “To get there first with the most men,” has with strange perverseness been so distorted in naval—and still more in popular—conception, that the second and more important consideration has been subordinated to the former and less essential. Force does not exist for mobility, but mobility for force. It is of no use to get there first unless, when the enemy in turn arrives, you have also the most men,—the greater force. This is especially true of the sea, because there inferiority of force—of gun power—cannot be compensated, as on land it at times may be, by judiciously using accidents of the ground. I do not propose to fall into an absurdity of my own by questioning the usefulness of higher speed, _provided_ the increase is not purchased at the expense of strictly offensive power; but the time has come to say plainly that its value is being exaggerated; that it is in the battleship secondary to gun power; that a battle fleet can never attain, nor maintain, the highest rate of any ship in it, except of that one which at the moment is the slowest, for it is a commonplace of naval action that fleet speed is that of the slowest ship; that not exaggerated speed, but uniform speed—sustained speed—is the requisite of the battle fleet; that it is not machinery, as is often affirmed, but brains and guns, that win battles and control of the sea. The true speed of war is not headlong precipitancy, but the unremitting energy which wastes no time.
