In the case of our attempting offensive operations against the distant coast of an enemy, we would be in the same position as a foreign enemy would be in when attacking our coast, in that our chances of success would be excellent if our fleet were considerably superior to the defending fleet in fighting power, and in the number and strength of scouts, and if the enemy coast possessed numerous undefended bays and islands which we could seize as bases. But even if the superiority of our fleet in fighting power and scouts was considerably greater than the enemy's our ultimate success would be doubtful, if the enemy's coast and islands were so protected by guns and mines and submarines that we could not get a base near the scene of operations. It is true that the British were able to maintain blockades of the French coast during many weary months without any base nearer than England--a place far away to ships whose only motive power was sails; but destroyers and submarines and mines did not then exist, and these agencies are much more valuable to the defender than to the blockader who has no base at hand. Our operations without a base on a distant enemy coast would be apt to degenerate into warding off a continual series of more or less minor attacks by the minor craft of the defender. The commander of our fleet would be constrained to keep his fighting force pretty close together, thus restricting his initiative; lest the entire enemy fleet catch a detached part out of supporting distance of the main body, and annihilate it with little loss to themselves. We could probably shut off most of the enemy's sea-borne commerce; and the war would become one of endurance between our fleet, on the one hand, and the economic forces and the morale of the enemy country on the other hand. In the case of operations carried on far away from the bases of both fleets, operations like those that the French and British carried on in the West Indies, the commanders-in-chief will naturally be much less directed by the admiralties at home than will a commander-in-chief operating near home; and the strategical advantage, as affected by the proximity of bases, and by the possession of the better chance for the initiative, will be reduced to its minimum.
