We need always to remember that in time of war the Navy is not to be used to defend harbors and sea-coast cities; we should perfect our system of coast fortifications. The only efficient use for the Navy is for offense. The only way in which it can efficiently protect our own coast against the possible action of a foreign navy is by destroying that foreign navy. For defense against a hostile fleet which actually attacks them, the coast cities must depend upon their forts, mines, torpedoes, submarines, and torpedo boats and destroyers. All of these together are efficient for defensive purposes, but they in no way supply the place of a thoroughly efficient navy capable of acting on the offensive; for parrying never yet won a fight. It can only be won by hard hitting, and an aggressive sea-going navy alone can do this hard hitting of the offensive type. But the forts and the like are necessary so that the Navy may be footloose. In time of war there is sure to be demand, under pressure, of fright, for the ships to be scattered so as to defend all kind of ports. Under penalty of terrible disaster, this demand must be refused. The ships must be kept together, and their objective made the enemies’ fleet. If fortifications are sufficiently strong, no modern navy will venture to attack them, so long as the foe has in existence a hostile navy of anything like the same size or efficiency. But unless there exists such a navy then the fortifications are powerless by themselves to secure the victory. For of course the mere deficiency means that any resolute enemy can at his leisure combine all his forces upon one point with the certainty that he can take it.
Until our battle fleet is much larger than at present it should never be split into detachments so far apart that they could not in event of emergency be speedily united. Our coast line is on the Pacific just as much as on the Atlantic. The interests of California, Oregon, and Washington are as emphatically the interests of the whole Union as those of Maine and New York, of Louisiana and Texas. The battle
