closely the extent of the influence of a victory; here we shall only observe that it reaches to the exhaustion of the superiority, that is, the resultant of the physical and moral relations. Now this superiority exhausts itself in the first place by the duties required from the forces on the theatre of war, and secondly by losses in combats; the diminution of force arising from these two causes cannot be essentially altered, whether the combats take place at the commencement or at the end, near the frontier, or further towards the interior of the country (vom oder hinten). We think, for example, that a victory gained by Buonaparte over the Russians at Wilna, 1812, would have carried him just as far as that of Borodino—assuming that it was equally great—and that a victory at Moscow would not have carried him any further; Moscow was, in either case, the limit of this sphere of victory. Indeed, it cannot be doubted for a moment that a decisive battle on the frontier (for other reasons) would have produced much greater results through victory, and then, perhaps, the sphere of its influence would have been wider. Therefore, in this view, also, the transfer of the decision to a point further back is not necessary for the defence.
In the chapter on the various means of resistance, that method of delaying the decision, which may be regarded as an extreme form, was brought before us under the name of retreat into the interior, and as a particular method of defence, in which the object is rather that the assailant should wear himself out, than that he should be destroyed by the sword on the field of battle. But it is only when such an intention predominates that the delaying of the decisive battle can be regarded as a peculiar method of resistance; for otherwise it is evident that an infinite number of gradations may be conceived in this method, and that these may be combined with all other means of defence. We therefore look upon the greater or less co-operation of the theatre of war, not as a special form of defence, but as nothing more than a discretionary introduction into the defence of the immovable means of resistance, just according as circumstances and the nature of the situation may appear to require.
