Lessons of the war with Spain and other articles

by A. T. Mahan

It was upon the Marietta that he had previously depended, in a measure, to thwart the attacks of these small vessels; but in such a contest as that with four armored cruisers she could scarcely count, and she was delaying his progress in the run immediately before him.

"The torpedo boat [he continues] was a rattlesnake to me, that I feared would get in his work while I was fighting the tiger; but I felt that the chances were that Cervera was bound to the West Indies, and so that the need of the Oregon there was so great that the risk of his turning south to meet me should be run, so I hurried to Bahia, and cabled to the Department my opinion of what the Oregon might do alone and in a running fight.... My object was to add the Oregon to our fleet, and not to meet the Spaniards, if it could be avoided."

It may be added that in this his intention coincided with the wish of the Department.

"So when, in Barbados, the reports came off that the Spanish fleet (and rumors had greatly increased its size) was at Martinique, that three torpedo boats had been seen from the island, I ordered coal to be loaded till after midnight, but left soon after dark, started west, then turned and went around the island"—that is, well to the eastward—"and made to the northward."

This was on the evening of May 18th. Six days later the ship was off the coast of Florida, and in communication with the Department.

The Oregon may properly be regarded as one of the three principal detachments into which the United States fleet was divided at the opening of the eventful week, May 12th-19th, and which, however they might afterwards be distributed around the strategic centre,—which we had chosen should be about Havana and Cienfuegos,—needed to be brought to it as rapidly as possible. No time was avoidably lost. On the evening of May 13th, eighteen hours after Cervera's appearance at Martinique was reported, the two larger divisions, under Sampson and Schley, were consciously converging upon our point of concentration at Key West; while the third, the Oregon, far more distant, was also moving to the same place in the purpose of the Department, though, as yet, unconsciously to herself. Sampson had over twenty-four hours' start of the Flying Squadron; and the distances to be traversed, from Puerto Rico and Hampton Roads, were practically the same.[3] But the former was much delayed by the slowness of the monitors, and, great as he felt the need of haste to be, and urgent as was the Department's telegram, received on the 15th, he very properly would not allow his vessels to separate until nearer their destination. Precautionary orders were sent by him to the Harvard and Yale—two swift despatch vessels then under his immediate orders—to coal to the utmost and to hold themselves at the end of a cable ready for immediate orders; while Commodore Remey, commanding at Key West, was directed to have every preparation complete for coaling the squadron on the 18th, when it might be expected to arrive. The St. Louis, a vessel of the same type as the Harvard, met the Admiral while these telegrams were being written. She was ordered to cut the cables at Santiago and Guantanamo Bay, and afterwards at Ponce, Puerto Rico.

The Flying Squadron had sailed at 4 P.M. of the 13th. Its fighting force consisted of the Brooklyn, armored cruiser, flagship; the Massachusetts, first-class, and the Texas, second-class, battleships. It is to be inferred from the departure of these vessels that the alarm about our own coast, felt while the whereabouts of the hostile division was unknown, vanished when it made its appearance. The result was, perhaps, not strictly logical; but the logic of the step is of less consequence than its undoubted military correctness. We had chosen our objective, and now we were concentrating upon it,—a measure delayed too long, though unavoidably. Commodore Schley was directed to call off Charleston for orders; for, while it is essential to have a settled strategic idea in any campaign, it is also necessary, in maritime warfare, at all events, to be ready to change a purpose suddenly and to turn at once upon the great objective,—which dominates and supersedes all others,—the enemy's navy, when a reasonable prospect of destroying it, or any large fraction of it, offers. When Schley left Hampton Roads, it was known only that the Spanish division had appeared off Martinique. The general intention, that our own should go to Key West, must therefore be held subject to possible modification, and to that end communication at a half-way point was imperative. No detention was thereby caused. At 4.30 P.M. of the 15th the Flying Squadron, which had been somewhat delayed by ten hours of dense fog, came off Charleston Bar, where a lighthouse steamer had been waiting since the previous midnight. From the officer in charge of her the Commodore received his orders, and at 6 P.M. was again under way for Key West, where he arrived on the 18th, anticipating by several hours Sampson's arrival in person, and by a day the coming of the slower ships of the other division.

But if it is desirable to ensure frequent direct communication with the larger divisions of the fleet, at such a moment, when their movements must be held subject to sudden change to meet the as yet uncertain developments of the enemy's strategy, it is still more essential to keep touch from a central station with the swift single cruisers, the purveyors of intelligence and distributors of the information upon which the conduct of the war depends. If the broad strategic conception of the naval campaign is correct, and the consequent action consistent, the greater fighting units—squadrons or fleets—may be well, or better, left to themselves, after the initial impulse of direction is given, and general instructions have been issued to their commanders. These greater units, however, cannot usually be kept at the end of a telegraph cable; yet they must, through cables, maintain, with their centres of intelligence, communication so frequent as to be practically constant. The Flying Squadron when off Cienfuegos, and Admiral Sampson's division at the time now under consideration, while on its passage from San Juan to Key West, are instances in point. Conversely, dependence may be placed upon local agents to report an enemy when he enters port; but when at sea for an unknown destination, it is necessary, if practicable, to get and keep touch with him, and to have his movements, actual and probable, reported. In short, steady communication must be maintained, as far as possible, between the always fixed points where the cables end, and the more variable positions where the enemy's squadrons and our own are, whether for a stay or in transit. This can be done only through swift despatch vessels; and for these, great as is the need that no time be wasted in their missions, the homely proverb, "more haste, less speed," has to be kept in mind. To stop off at a wayside port, to diverge even considerably from the shortest route, may often be a real economy of time.

The office of cruisers thus employed is to substitute certainty for conjecture; to correct or to confirm, by fuller knowledge, the inferences upon which the conduct of operations otherwise so much depends. Accurate intelligence is one of the very first desiderata of war, and as the means of obtaining and transmitting it are never in excess of the necessities, those means have to be carefully administered. Historically, no navy ever has had cruisers enough; partly because the lookout and despatch duties themselves are so extensive and onerous; partly because vessels of the class are wanted for other purposes also,—as, for instance, in our late war, for the blockade of the Cuban ports, which was never much more than technically "effective," and for the patrolling of our Atlantic seaboard. True economical use of the disposable vessels, obtaining the largest results with the least expenditure of means never adequate, demands much forethought and more management, and is best effected by so arranging that the individual cruisers can be quickly got hold of when wanted. This is accomplished by requiring them to call at cable ports and report; or by circumscribing the area in which they are to cruise, so that they can be readily found; or by prescribing the course and speed they are to observe,—in short, by ensuring a pretty close knowledge of their position at every moment.

For the purposes of intelligence, a cruiser with a roving commission, or one which neglects to report its movements when opportunity offers, is nearly useless; and few things are more justly exasperating than the failure of a cruiser to realize this truth in practice. Of course, no rule is hard and fast to bind the high discretion of the officer senior on the spot; but if the captains of cruisers will bear in mind, as a primary principle, that they, their admirals, and the central office, are in this respect parts of one highly specialized and most important system in which co-operation must be observed, discretion will more rarely err in these matters, where errors may be so serious. That with a central office, admirals, and captains, all seeking the same ends, matters will at times work at cross purposes, only proves the common experience that things will not always go straight here below. When Nelson was hunting for the French fleet before the battle of the Nile, his flagship was dismasted in a gale of wind off Corsica. The commander of the frigates, his lookout ships, having become separated in the gale, concluded that the Admiral would have to return to Gibraltar, and took his frigates there. "I thought he knew me better," commented Nelson. "Every moment I have to regret the frigates having left me," he wrote later; "the return to Syracuse," due to want of intelligence, "broke my heart, which on any extraordinary anxiety now shows itself." It is not possible strictly to define official discretion, nor to guard infallibly against its misuse; but, all the same, it is injurious to an officer to show that he lacks sound judgment.
