The unsatisfactory condition of the coast defences, whereby the navy lost the support of its complementary factor in the scheme of national sea power, imposed a vicious, though inevitable, change in the initial plan of campaign, which should have been directed in full force against the coast of Cuba. The four newer monitors on the Atlantic coast, if distributed among our principal ports, were not adequate, singly, to resist the attack which was suggested by the possibilities of the case—though remote—and still more by the panic among certain of our citizens. On the other hand, if the four were massed and centrally placed, which is the correct disposition of any mobile force, military or naval, intended to counteract the attack of an enemy whose particular line of approach is as yet uncertain, their sluggishness and defective nautical qualities would make them comparatively inefficient. New York, for instance, is a singularly central and suitable point, relatively to our northern Atlantic seaboard, in which to station a division intended to meet and thwart the plans of a squadron like Cervera's, if directed against our coast ports, in accordance with the fertile imaginations of evil which were the fashion in that hour. Did the enemy appear off either Boston, the Delaware, or the Chesapeake, he could not effect material injury before a division of ships of the Oregon class would be upon him; and within the limits named are found the major external commercial interests of the country as well as the ocean approaches along which they travel. But had the monitors been substituted for battleships, not to speak of their greater slowness, their inferiority as steady gun-platforms would have placed them at a serious disadvantage if the enemy were met outside, as he perfectly well might be.
It was probably such considerations as these, though the writer was not privy to them, that determined the division of the battle fleet, and the confiding to the section styled the Flying Squadron the defence of the Atlantic coast for the time being. The monitors were all sent to Key West, where they would be at hand to act against Havana; the narrowness of the field in which that city, Key West, and Matanzas are comprised making their slowness less of a drawback, while the moderate weather which might be expected to prevail would permit their shooting to be less inaccurate. The station of the Flying Squadron in Hampton Roads, though not so central as New York relatively to the more important commercial interests, upon which, if upon any, the Spanish attack might fall, was more central as regards the whole coast; and, above all, was nearer than New York to Havana and to Puerto Rico. The time element also entered the calculations in another way, for a fleet of heavy ships is more certainly able to put to sea at a moment's notice, in all conditions of tide and weather, from the Chesapeake than from New York Bay. In short, the position chosen may be taken to indicate that, in the opinion of the Navy Department and its advisers, Cervera was not likely to attempt a dash at an Atlantic port, and that it was more important to be able to reach the West Indies speedily than to protect New York or Boston,—a conclusion which the writer entirely shared.
The country, however, should not fail to note that the division of the armored fleet into two sections, nearly a thousand miles apart, though probably the best that could be done under all the circumstances of the moment, was contrary to sound practice; and that the conditions which made it necessary should not have existed. Thus, deficient coast protection reacts unfavorably upon the war fleet, which in all its movements should be free from any responsibility for the mere safety of the ports it quits. Under such conditions as then obtained, it might have been possible for Spain to force our entire battle fleet from its offensive undertaking against Cuba, and to relegate it to mere coast defence. Had Cervera's squadron, instead of being despatched alone to the Antilles, been recalled to Spain, as it should have been, and there reinforced by the two armored ships which afterwards went to Suez with Cámara, the approach of this compact body would have compelled our fleet to concentrate; for each of our divisions of three ships—prior to the arrival of the Oregon—would have been too weak to hazard an engagement with the enemy's six. When thus concentrated, where should it be placed? Off Havana, or at Hampton Roads? It could not be at both. The answer undoubtedly should be, "Off Havana;" for there it would be guarding the most important part of the enemy's coast, blocking the access to it of the Spanish fleet, and at the same time covering Key West, our naval base of operations. But if the condition of our coast defences at all corresponded to the tremors of our seaport citizens, the Government manifestly would be unable to hold the fleet thus at the front. Had it, on the contrary, been impossible for an enemy's fleet to approach nearer than three miles to our sea-coast without great and evident danger of having ships damaged which could not be replaced, and of wasting ammunition at ranges too long even for bombardments, the Spanish battle fleet would have kept away, and would have pursued its proper object of supporting their campaign in Cuba by driving off our fleet—if it could. It is true that no amount of fortification will secure the coasting trade beyond easy gunshot of the works; but as the enemy's battle fleet could not have devoted itself for long to molesting the coasters—because our fleet would thereby be drawn to the spot—that duty must have devolved upon vessels of another class, against which we also would have provided, and did provide, by the squadron of cruisers under Commodore Howell. In short, proper coast defence, the true and necessary complement of an efficient navy, releases the latter for its proper work,—offensive, upon the open seas, or off the enemy's shores.
The subject receives further illumination when we consider, in addition to the hypothetical case just discussed,—the approach of six Spanish ships,—the actual conditions at the opening of the campaign. We had chosen Cuba for our objective, had begun our operations, Cervera was on his way across the ocean, and our battle fleet was divided and posted as stated. It was reasonable for us to estimate each division of our ships—one comprising the New York, Iowa, and Indiana, the other the Brooklyn, Massachusetts, and Texas—as able to meet Cervera's four, these being of a class slightly inferior to the best of ours. We might at least flatter ourselves that, to use a frequent phrase of Nelson's, by the time they had soundly beaten one of these groups, they would give us no more trouble for the rest of the year. We could, therefore, with perfect military propriety, have applied the two divisions to separate tasks on the Cuban coast, if our own coast had been adequately fortified.
The advantage—nay, the necessity—of thus distributing our battleships, having only four enemies to fear, will appear from a glance at the map of Cuba. It will there be seen that the island is particularly narrow abreast of Havana, and that from there, for a couple of hundred miles to the eastward, extends the only tolerably developed railroad system, by which the capital is kept in communication with the seaports, on the north coast as far as Sagua la Grande, and on the south with Cienfuegos and Batabano. This narrowness, and the comparative facility of communication indicated by the railroads, enabled Spain, during her occupation, effectually to prevent combined movements between the insurgents in the east and those in the west; a power which Weyler endeavored to increase by the trocha system,—a ditch or ditches, with closely supporting works, extending across the island. Individuals, or small parties, might slip by unperceived; but it should have been impossible for any serious co-operation to take place. The coast-wise railroads, again, kept Havana and the country adjacent to them in open, if limited, communication with the sea, so long as any one port upon their lines remained unblockaded. For reasons such as these, in this belt of land, from Havana to Sagua and Cienfuegos, lay the chief strength of the Spanish tenure, which centred upon Havana; and in it the greatest part of the Spanish army was massed. Until, therefore, we were ready to invade, which should not have been before the close of the rainy season, the one obvious course open to us was to isolate the capital and the army from the sea, through which supplies of all kinds—daily bread, almost, of food and ammunition—were introduced; for Cuba, in these respects, produces little.
To perfect such isolation, however, it was necessary not only to place before each port armed cruisers able to stop merchant steamers, but also to give to the vessels so stationed, as well on the south as on the north side, a backbone of support by the presence of an armored fleet, which should both close the great ports—Havana and Cienfuegos—and afford a rallying-point to the smaller ships, if driven in by the appearance of Cervera's division. The main fleet—three armored ships—on the north was thus used, although the blockade, from the fewness of available cruisers, was not at first extended beyond Cardenas. On the south
