Most of the subjects have been already touched upon in the sixth book, and by their mere reflection, throw sufficient light on the attack.
Moreover, the conception of an enclosed theatre of war, has a nearer relation to the defence than to the attack. Many of the leading points, the object of attack, the sphere of action of victory, etc., have been already treated of in that book, and that which is most decisive and essential on the nature of the attack, cannot be made to appear until we get to the plan of war: still there remains a good deal to say here, and we shall again commence with the campaign, in which a great decision is positively intended.
The first aim of the attack is a victory. To all the advantages which the defender finds in the nature of his situation, the assailant can only oppose superior numbers; and, perhaps, in addition, the slight advantage which the feeling of being the offensive and advancing side gives an army. The importance of this feeling, however, is generally overrated; for it does not last long, and will not hold out against real difficulties. Of course, we assume that the defender is as faultless and judicious in all he does as the aggressor. Our object in this observation is to set aside those vague ideas of sudden attack and surprise, which, in the attack, are generally assumed to be fertile sources of victory, and which yet, in reality, never occur except under special circumstances. The nature of the real strategic surprise, we have already spoken of elsewhere.—If, then, the attack is inferior in physical power, it must have the ascendancy in moral power, in order to make up for the disadvantages which are inherent in the offensive form; if the superiority in that way is also wanting, then there are no good grounds for the attack, and it will not succeed.
As prudence is the real genius of the defender, so boldness and self-confidence must animate the assailant. We do not mean that the opposite qualities in each case may be altogether wanting, but that the qualities named have the greatest affinity to the attack and defence respectively. These qualities are only in reality necessary because action in war is no mere mathematical calculation; it is activity which is carried on if not in the dark, at all events in a feeble twilight, in which we must trust ourselves to the leader who is best suited to carry out the aim we have in view.—The weaker the defender shows himself morally, the bolder the assailant should become.
For victory, it is necessary that there should be a battle between the enemy’s principal force and our own. This is less doubtful as regards the attack than in regard to the defence, for the assailant goes in search of the defender in his position. But we have maintained (in treating of the defensive) that the offensive should not seek the defender out if he has placed himself in a false position, because he may be sure that the defender will seek him out, and then he will have the advantage of fighting where the defender has not prepared the ground. Here all depends on the road and direction which have the greatest importance; this is a point which was not examined in the defence, being reserved for the present chapter. We shall, therefore, say what is necessary about it here.
