Offence and Defence Book VI: Chapter 1.—Conception of Defence. What is defence in conception? The warding off a blow. What is then its characteristic sign? The state of expectancy (or of waiting for this blow). This is the sign by which we always recognise an act as of a defensive character, and by this sign alone can the defensive be distinguished from the offensive in war. But inasmuch as an absolute defence completely contradicts the idea of war, because there would then be war carried on by one side only, it follows that the defence in war can only be relative and the above distinguishing signs must therefore only be applied to the essential idea or general conception: it does not apply to all the separate acts which compose the war. A partial combat is defensive if we receive the onset, the charge of the enemy; a battle is so if we receive the attack, that is, wait for the appearance of the enemy before our position and within range of our fire; a campaign is defensive if we wait for the entry of the enemy into our theatre of war. In all these cases the sign of waiting for and warding off belongs to the general conception, without any contradiction arising with the conception of war, for it may be to our advantage to wait for the charge against our bayonets, or the attack on our position or our theatre of war. But as we must return the enemy’s blows if we are really to carry on war on our side, therefore this offensive act in defensive war takes place more or less under the general title defensive—that is to say, the offensive of which we make use falls under the conception of position or theatre of war. We can, therefore, in a defensive campaign fight offensively, in a defensive battle we may use some divisions for offensive purposes, and lastly, while remaining in position awaiting the enemy’s onslaught, we still make use of the offensive by sending at the same time balls into the enemy’s ranks. The defensive form in war is therefore no mere shield but a shield formed of blows delivered with skill. 2.—Advantages of the Defensive. What is the object of defence? To preserve. To preserve is easier than to acquire; from which follows at once that the means on both sides being supposed equal, the defensive is easier than the offensive. But in what consists the greater facility of preserving or keeping possession? In this, that all time which is not turned to any account falls into the scale in favour of the defence. He reaps where he has not sowed. Every suspension of offensive action, either from erroneous views, from fear or from indolence, is in favour of the side acting defensively. This advantage saved the State of Prussia from ruin more than once in the Seven Years’ War. It is one which derives itself from the conception and object of the defensive, lies in the nature of all defence, and in ordinary life, particularly in legal business which bears so much resemblance to war, it is expressed by the Latin proverb, Beati sunt possidentes. Another advantage arising from the nature of war and belonging to it exclusively, is the aid afforded by locality or ground; this is one of which the defensive form has a preferential use. Having established these general ideas we now turn more directly to the subject. In tactics every combat, great or small, is defensive if we leave the initiative to the enemy, and wait for his appearance in our front. From that moment forward we can make use of all offensive means without losing the said two advantages of the defence, namely, that of waiting for, and that of ground. In strategy, at first, the campaign represents the battle, and the theatre of war the position; but afterwards the whole war takes the place of the campaign, and the whole country that of the theatre of war, and in both cases the defensive remains that which it was in tactics. It has been already observed in a general way that the defensive is easier than the offensive; but as the defensive has a negative object, that of preserving, and the offensive a positive object that of conquering, and as the latter increases our own means of carrying on war, but the preserving does not, therefore in order to express ourselves distinctly, we must say, that the defensive form of war is in itself stronger than the offensive. This is the result we have been desirous of arriving at; for although it lies completely in the nature of the thing, and has been confirmed by experience a thousand times, still it is completely contrary to prevalent opinion—a proof how ideas may be confused by superficial writers. If the defensive is the stronger form of conducting war, but has a negative object, it follows of itself that we must only make use of it so long as our weakness compels us to do so, and that we must give up that form as soon as we feel strong enough to aim at the positive object. Now as the state of our circumstances is usually improved in the event of our gaining a victory through the assistance of the defensive, it is therefore, also, the natural course in war to begin with the defensive, and to end with the offensive. It is therefore just as much in contradiction with the conception of war to suppose the defensive the ultimate object of the war as it was a contradiction to understand passivity to belong to all the parts of the defensive, as well as to the defensive as a whole. In other words: a war in which victories are merely used to ward off blows, and where there is no attempt to return the blow, would be just as absurd as a battle in which the most absolute defence (passivity) should everywhere prevail in all measures. Against the justice of this general view many examples might be quoted in which the defensive continued defensive to the last, and the assumption of the offensive was never contemplated; but such an objection could only be urged if we lost sight of the fact that here the question is only about general ideas (abstract ideas), and that examples in opposition to the general conception we are discussing are all of them to be looked upon as cases in which the time for the possibility of offensive reaction had not yet arrived. In the Seven Years’ War, at least in the last three years of it, Frederick the Great did not think of an offensive; indeed we believe further, that generally speaking, he only acted on the offensive at any time in this war as the best means of defending himself; his whole situation compelled him to this course, and it is natural that a general should aim more immediately at that which is most in accordance with the situation in which he is placed for the time being. Nevertheless, we cannot look at this example of a defence upon a great scale without supposing that the idea of a possible counterstroke against Austria lay at the bottom of the whole of it, and saying to ourselves, the moment for that counterstroke had not arrived before the war came to a close. The conclusion of peace shows that this idea is not without foundation even in this instance; for what could have actuated the Austrians to make peace except the thought that they were not in a condition with their own forces alone to make head against the talent of the king; that to maintain an equilibrium their exertions must be greater than heretofore, and that the slightest relaxation of their efforts would probably lead to fresh losses of territory. And, in fact, who can doubt that if Russia, Sweden, and the army of the German Empire had ceased to act together against Frederick the Great he would have tried to conquer the Austrians again in Bohemia and Moravia? Having thus defined the true meaning of the defensive, having defined its boundaries, we return again to the assertion that the defensive is the stronger form of making war. Upon a closer examination, and comparison of the offensive and defensive, this will appear perfectly plain; but for the present we shall confine ourselves to noticing the contradiction in which we should be involved with ourselves, and with the results of experience by maintaining the contrary to be the fact. If the offensive form was the stronger there would be no further occasion ever to use the defensive, as it has merely a negative object, every one would be for attacking, and the defensive would be an absurdity. On the other hand, it is very natural that the higher object should be purchased by greater sacrifices. Whoever feels himself strong enough to make use of the weaker form has it in his power to aim at the greater object; whoever sets before himself the smaller object can only do so in order to have the benefit of the stronger form—If we look to experience, such a thing is unheard of as any one carrying on a war upon two different theatres—offensively on one with the weaker army, and defensively on the other with his strongest force But if the reverse of this has everywhere and at all times taken place that shows plainly that generals although their own inclination prompts them to the offensive, still hold the defensive to be the stronger form. We have still in the next chapters to explain some preliminary points. About HackerNoon Book Series: We bring you the most important technical, scientific, and insightful public domain books.
