The title chosen by its author for this little volume would assuredly commend it to the Naval Service, even if that author's name were not—as it is—a household word with more than one generation of naval officers. But to such of the general public as are not yet familiar with Mr Thursfield's writings a brief word of introduction may perhaps be useful. For the matters herein dealt with are by no means of interest only to the naval profession. They have their bearing also on every calling and trad

Intelligent readers of this little Manual will perceive at once that it pretends to be nothing more than an introduction, quite elementary in character, to the study of naval warfare, its history, and its principles as displayed in its history. As such, I trust it may be found useful by those of my countrymen who desire to approach the naval problems which are constantly being brought to their notice and consideration with sound judgment and an intelligent grasp of the principles involved in the

INTRODUCTORY War is the armed conflict of national wills, an appeal to force as between nation and nation. Naval warfare is that part of the conflict which takes place on the seas. The civilized world is divided into separate, independent States or nations, each sovereign within its own borders. Each State pursues its own ideas and aims and embodies them in a national policy; and so far as this policy affects only its own citizens, it is subject to no control except that of the national conscien

THE COMMAND OF THE SEA We have seen that when two States go to war the primary object of each is to subdue and if possible to destroy the armed forces of the other. Until that is done either completely, or to such an extent as to induce the defeated belligerent to submit, the conflict of wills cannot be determined, and the two States cannot return to those normal relations, involving no violence or force, which constitute a state of peace. If they have a common frontier this circumstance indicat

DISPUTED COMMAND—BLOCKADE I have so far treated blockade as the initial stage of a struggle for the command of the sea. That appears to me to be the logical order of treatment, because when two naval Powers go to war it is almost certain that the stronger of the two will at the outset attempt to blockade the naval forces of the other. The same thing is likely to happen even if the two are approximately equal in naval force, but in that case the blockade is not likely to be of long duration, beca

DISPUTED COMMAND—THE FLEET IN BEING We have seen that blockade is only a means to an end, that end being the destruction or surrender of the armed forces of the enemy. We have seen also that that end cannot be obtained by blockade alone. All that a military blockade can do is by a judicious disposition of superior force, either to prevent the enemy coming out at all, or to secure that if he does come out he shall be brought to action. The former method is only applicable where the blockader's su

DISPUTED COMMAND IN GENERAL The condition of disputed command of the sea is the normal condition at the outbreak of any war in which operations at sea are involved between two belligerents of approximately equal strength, or indeed between any two belligerents, the weaker of whom is sufficiently inspired by the animus pugnandi —or it may be by other motives rather political than strategic in character—to try conclusions with his adversary in the open. This follows immediately from the nature of

INVASION England has not been invaded since A.D. 1066, when, the country having no fleet in being, William the Conqueror effected a landing and subjugated the kingdom. During the eight centuries and more that have since elapsed, every country in Europe has been invaded and its capital occupied, in many cases more than once. It is by no means for lack of attempts to invade her that England has been spared the calamity of invasion for more than eight hundred years. It is not because she has had at

COMMERCE IN WAR The maritime trade of a nation at war has always been regarded by the other belligerent as his legitimate prey. In the Dutch Wars the suppression of the enemy's commerce was the main objective of both parties to the conflict. In all wars in which either belligerent has any commerce afloat worth considering one belligerent may always be expected to do all that he can for its capture or suppression, while the other will do as much as he can for its defence. In proportion to the vol

THE DIFFERENTIATION OF NAVAL FORCE A warship, considered in the abstract, may be defined as a vessel employed, and generally constructed, for the purpose of conveying across the seas to the place of conflict, the weapons that are to be used in conflict, the men who are to use them, and all such stores, whether of food or other supplies, as will give to the vessel as large a measure of enduring mobility as is compatible with her displacement. If we confine our attention to the period posterior to

THE DISTRIBUTION AND SUPPLY OF NAVAL FORCE The measure of naval strength required by any State is determined mainly by the naval strength of its possible adversaries in the event of war, and only in a secondary degree by the volume of the maritime interests which it has to defend. Paradoxical as the latter half of this proposition may seem at first sight, it can easily be shown to be sound. The maritime interests, territorial and commercial, of the British Empire are beyond all comparison greate
