completed. Not only was Liao-yang the Russian point of concentration, but it also was a sound position both for defending Korea and covering the siege of Port Arthur. Once secured, it gave the Japanese all the advantages of defence and forced the Russians to exhaust themselves in offensive operations which were beyond their strength. Nor was it only ashore that this advantage was gained. The success of the system, which culminated in the fall of Port Arthur, went further still. Not only did it make Japan relatively superior at sea, but it enabled her to assume a naval defensive and so to force the final naval decision on Russia with every advantage of time, place, and strength in her own favour.

      By the battle of Tsushima the territorial object was completely isolated by sea, and the position of Japan in Korea was rendered as impregnable as that of Wellington at Torres Vedras. All that remained was to proceed to the third stage and demonstrate to Russia that the acceptance of the situation that had been set up was more to her advantage than the further attempt to break it down. This the final advance to Mukden accomplished, and Japan obtained her end very far short of having overthrown her enemy. The offensive power of Russia had never been so strong, while that of Japan was almost if not quite exhausted.

      Approached in this way, the Far Eastern struggle is seen to develop on the same lines as all our great maritime wars of the past, which continental strategists have so persistently excluded from their field of study. It presents the normal three phases—the initial offensive movement to seize the territorial object, the secondary phase, which forces an attenuated offensive on the enemy, and the final stage of pressure, in which there is a return to the offensive "according," as Jomini puts it, "to circumstances and your relative force in order to obtain the cession desired."

      It must not of course be asked that these phases shall be always clearly defined. Strategical analysis can never give exact results. It aims only at approximations, at groupings which will serve to guide but will always leave much to the judgment. The three phases in the Russo-Japanese War, though unusually well defined, continually overlapped. It must be so; for in war the effect of an operation is never confined to the limits of its immediate or primary intention. Thus the occupation of Korea had the secondary defensive effect of covering the home country, while the initial blow which Admiral Togo delivered at Port Arthur to cover the primary offensive movement proved, by the demoralisation it caused in the Russian fleet, to be a distinct step in the secondary phase of isolating the conquest. In the later stages of the war the line between what was essential to set up the second phase of perfecting the isolation and the third phase of general pressure seems to have grown very nebulous.

      It was at this stage that the Japanese strategy has been most severely criticised, and it was just here they seem to have lost hold of the conception of a limited war, if in fact they had ever securely grasped the conception as the elder Pitt understood it. It has been argued that in their eagerness to deal a blow at the enemy's main army they neglected to devote sufficient force to reduce Port Arthur, an essential step to complete the second phase. Whether or not the exigencies of the case rendered such distribution of force inevitable or whether it was due to miscalculation of difficulties, the result was a most costly set-back. For not only did it entail a vast loss of time and life at Port Arthur itself, but when the sortie of the Russian fleet in June brought home to them their error, the offensive movement on Liao-yang had to be delayed, and the opportunity passed for a decisive counter-stroke at the enemy's concentration ashore.

      This misfortune, which was to cost the Japanese so dear, may perhaps be attributed at least in part to the continental influences under which their army had been trained. We at least can trace the unlimited outlook in the pages of the German Staff history. In dealing with the Japanese plan of operations it is assumed that the occupation of Korea and the isolation of Port Arthur were but preliminaries to a concentric advance on Liao-yang, "which was kept in view as the first objective of the operations on land." But surely on every theory of the war the first objective of the Japanese on land was Seoul, where they expected to have to fight their first important action against troops advancing from the Yalu; and surely their second was Port Arthur, with its fleet and arsenal, which they expected to reduce with little more difficulty than they had met with ten years before against the Chinese. Such at least was the actual progression of events, and a criticism which regards operations of such magnitude and ultimate importance as mere incidents of strategic deployment is only to be explained by the domination of the Napoleonic idea of war, against the universal application of which Clausewitz so solemnly protested. It is the work of men who have a natural difficulty in conceiving a war plan that does not culminate in a Jena or a Sedan. It is a view surely which is the child of theory, bearing no relation to the actuality of the war in question and affording no explanation of its ultimate success. The truth is, that so long as the Japanese acted on the principles of limited war, as laid down by Clausewitz and Jomini and plainly deducible from our own rich experience, they progressed beyond all their expectations, but so soon as they departed from them and suffered themselves to be confused with continental theories they were surprised by unaccountable failure.

      The expression "Limited war" is no doubt not entirely happy. Yet no other has been found to condense the ideas of limited object and limited interest, which are its special characteristics. Still if the above example be kept in mind as a typical case, the meaning of the term will not be mistaken. It only remains to emphasise one important point. The fact that the doctrine of limited war traverses the current belief that our primary objective must always be the enemy's armed forces is liable to carry with it a false inference that it also rejects the corollary that war means the use of battles. Nothing is further from the conception. Whatever the form of war, there is no likelihood of our ever going back to the old fallacy of attempting to decide wars by manoeuvres. All forms alike demand the use of battles. By our fundamental theory war is always "a continuation of political intercourse, in which fighting is substituted for writing notes." However great the controlling influence of the political object, it must never obscure the fact that it is by fighting we have to gain our end.

      It is the more necessary to insist on this point, for the idea of making a piece of territory your object is liable to be confused with the older method of conducting war, in which armies were content to manoeuvre for strategical positions, and a battle came almost to be regarded as a mark of bad generalship. With such parading limited war has nothing to do. Its conduct differs only from that of unlimited war in that instead of having to destroy our enemy's whole power of resistance, we need only overthrow so much of his active force as he is able or willing to bring to bear in order to prevent or terminate our occupation of the territorial object.

      The first consideration, then, in entering on such a war is to endeavour to determine what the force will amount to. It will depend, firstly, on the importance the enemy attaches to the limited object, coupled with the nature and extent of his preoccupations elsewhere, and, secondly, it will depend upon the natural difficulties of his lines of communication and the extent to which we can increase those difficulties by our conduct of the initial operations. In favourable circumstances therefore (and here lies the great value of the limited form) we are able to control the amount of force we shall have to encounter. The most favourable circumstances and the only circumstances by which we ourselves can profit are such as permit the more or less complete isolation of the object by naval action, and such isolation can never be established until we have entirely overthrown the enemy's naval forces.

      Here, then, we enter the field of naval strategy. We can now leave behind us the theory of war in general and, in order to pave the way to our final conclusions, devote our attention to the theory of naval warfare in particular.

      THEORY OF NAVAL WAR

      CHAPTER ONE

      THEORY OF THE OBJECT—COMMAND OF THE SEA

      The object of naval warfare must always be directly or indirectly either to secure the command of the sea or to prevent the enemy from securing it.

      The second part of the proposition should be noted with special care in order to exclude a habit of thought, which is one of the commonest sources of error in naval speculation. That error is the very general assumption that if one belligerent loses the command of the sea it passes at once to the other belligerent. The most cursory study of naval history is enough to reveal the falseness of such an assumption. It tells us that
