Home Bases.—A home base is, as its name implies, a base situated in the home country. The most usual type of the home naval base is the navy-yard, though few navy-yards can meet all the requirements of a naval base. The New York navy-yard, for instance, which is our most important yard, lacks three of the most vital attributes of a naval base, in that it has no means for receiving and protecting a large fleet, it cannot be approached by large ships except at high tide, and it could not receive a seriously injured battleship at any time, because the channel leading to it is too shallow.

Home bases that approach perfection were evidenced after the battle off the Skagerak; for the wounded ships of both sides took refuge after the battle in protected bases, where they were repaired and refitted, and resupplied with fighting men and fuel. These bases seem to have been so located, so protected, and so equipped, as to do exactly what bases are desired to do; they were "bases of operations" in the best sense. The fleets of the opposing sides started from those bases as nearly ready as human means and foresight could devise, returned to them for refreshment after the operations had been concluded, and, during the operations, were based upon those bases. If the bases of either fleet had been improperly located, or inadequately protected or equipped, that fleet would not have been so completely ready for battle as, in fact, it was; and it could not have gone to its base for shelter and repairs so quickly and so surely as, in fact, it did. Many illustrations can be found in history of the necessity for naval bases; but the illustration given by this battle of May 31 is of itself so perfect and convincing, that it seems hardly necessary or even desirable to bring forward any others.

The fact of the nearness to each other of the bases of the two contending fleets—the nearness of Germany and Great Britain in other words—coupled with the nearness of the battle itself to the bases, and the fact that both fleets retired shortly afterward to the bases, bring out in clear relief the efficacy of bases; but nevertheless their efficacy would have been even more strongly shown if the battle had been near to the bases of the more powerful fleet, but far from the bases of the other fleet—as was the case at the battle, near Tsushima, in the Japan Sea.

Of course the weaker fleet in the North Sea battle would not have been drawn into battle under such conditions, because it would not have had a safe refuge to retreat to. It was the proximity of an adequate naval base, that could be approached through protected waters only, which justified the weaker fleet in dashing out and taking advantage of what seemed to be an opportunity. Similarly, if the Russian fleet in the Japan Sea had had a base near by, from which it had issued ready in all ways, and to which it could have retired as soon as the battle began to go against it, the Russian disaster might not have occurred, and full command of the sea by the Japanese might have been prevented. But there being no base or harbor of refuge, disaster succeeded disaster in a cumulative fashion, and the Russian fleet was annihilated in deep water.

If a naval base were lacking to the more powerful fleet, as was the case in the battle of Manila, the effect would in many cases be but slight—as at Manila. If, however, the more powerful fleet were badly injured, the absence of a base would be keenly felt and might entail disaster in the future, even though the more powerful fleet were actually victorious. The Japanese fleet was practically victorious at the battle of August 10, near Port Arthur; but if it had not been able to refit and repair at a naval base, it would have met the Russian fleet later with much less probability of success.

Mahan states that the three main requirements in a naval base are position, resources, and strength; and of these he considers that position is the most important; largely because resources and strength can be artificially supplied, while position is the gift of nature, and cannot be moved or changed.

Mahan's arguments seem to suggest that the bases he had in mind were bases distant from home, not home bases; since reference is continually made by him to the distance and direction of bases from important strategic points of actual or possible enemies.

His arguments do not seem to apply with equal force to home bases, for the reason that home bases are intended primarily as bases from which operations are to start; secondarily as bases to which fleets may return, and only remotely as bases during operations; whereas, distant bases are intended as points from which operations may continually be carried on, during the actual prosecution of a war. The position of a home base, for instance, as referred to any enemy's coasts or bases, is relatively unimportant, compared with its ability to fit out a fleet; while, on the other hand, the position of distant bases, such as Hong-Kong, Malta, or Gibraltar, relatively to the coasts of an enemy, is vital in the extreme. It is the positions of these three bases that make them so valuable to their holders; placed at points of less strategic value, the importance of those bases would be strategically less.

Home bases are valuable mainly by reason of their resources. This does not mean that position is an unimportant factor; it does not mean, for instance, that a naval base would be valuable if situated in the Adirondack Mountains, no matter how great resources it might have. It does mean, however, that the "position" that is important for a home base is the position that the base holds relatively to large home commercial centres and to the open sea. New York, for instance, could be made an excellent naval base, mainly because of the enormous resources that it has and its nearness to the ocean. Philadelphia, likewise, could be made valuable, though Philadelphia's position relatively to deep water is far from good. "Position," as used in this sense, is different from the "position" meant by Mahan, who used the word in its strategic sense. The position of Philadelphia relatively to deep water could be changed by simply deepening the channel of the Delaware; but no human power could change the strategic position of Malta or Gibraltar.

Yet for even home bases, position, resources, and strength must be combined to get a satisfactory result; the "position" not being related to foreign naval bases, however, but to large industrial establishments, mainly in order that working men of various classes may be secured when needed. The requirements of work on naval craft are so discontinuous that steady employment can be provided for comparatively few men only; so that a sort of reservoir is needed, close at hand, which can be drawn up when men are needed, and into which men can be put back, whenever the need for them has ceased. And the same commercial and industrial conditions that assure a supply of skilled workers, assure a supply of provisions and all kinds of material as well.
