the enemy’s forces therein engaged—and if its object can often be attained as well without the combat taking place at all, by merely making a resolve to fight, and by the circumstances to which this resolution gives rise—then that explains how a whole campaign may be carried on with great activity without the actual combat playing any notable part in it.
That this may be so military history proves by a hundred examples. How many of those cases can be justified, that is, without involving a contradiction and whether some of the celebrities who rose out of them would stand criticism, we shall leave undecided, for all we have to do with the matter is to show the possibility of such a course of events in War.
We have only one means in War—the battle; but this means, by the infinite variety of paths in which it may be applied, leads us into all the different ways which the multiplicity of objects allows of, so that we seem to have gained nothing; but that is not the case, for from this unity of means proceeds a thread which assists the study of the subject, as it runs through the whole web of military activity and holds it together.
