Decision of the Combat

No battle is decided in a single moment, although in every battle there arise moments of crisis, on which the result depends. The loss of a battle is, therefore, a gradual falling of the scale. But there is in every combat a point of time when it may be regarded as decided, in such a way that the renewal of the fight would be a new battle, not a continuation of the old one. To have a clear notion on this point of time, is very important, in order to be able to decide whether, with the prompt assistance of reinforcements, the combat can again be resumed with advantage.

Often in combats which are beyond restoration new forces are sacrificed in vain; often through neglect the decision has not been seized when it might easily have been secured. Here are two examples, which could not be more to the point:

When the Prince of Hohenlohe, in 1806, at Jena, with 35,000 men opposed to from 60,000 to 70,000, under Bonaparte, had accepted battle, and lost it -- but lost it in such a way that the 35,000 might be regarded as dissolved -- General Rüuchel undertook to renew the fight with about 12,000; the consequence was that in a moment his force was scattered in like manner.

On the other hand, on the same day at Auerstadt, the Prussians maintained a combat with 25,000, against Davoust, who had 28,000, until midday, without success, it is true, but still without the force being reduced to a state of dissolution without even greater loss than the enemy, who was very deficient in cavalry; but they neglected to use the reserve of 18,000, under General Kalkreuth, to restore the battle which, under these circumstances, it would have been impossible to lose.

Each combat is a whole in which the partial combats combine themselves into one total result. In this total result lies the decision of the combat. This success need not be exactly a victory such as we have denoted in the sixth chapter, for often the preparations for that have not been made, often there is no opportunity if the enemy gives way too soon, and in most cases the decision, even when the resistance has been obstinate, takes place before such a degree of success was attained as would completely satisfy the idea of a victory.

We therefore ask, Which is commonly the moment of the decision, that was to say, that moment when a fresh, effective, of course not disproportionate, force, can no longer turn a disadvantageous battle?

If we pass over false attacks, which in accordance with their nature are properly without decision, then

1 If the possession of a movable object was the object of the combat, the loss of the same is always the decision.

2 If the possession of ground was the object of the combat, then the decision generally lies in its loss. Still not always, only if this ground is of peculiar strength, ground which is easy to pass over, however important it may be in other respects, can be re-taken without much danger.

3 But in all other cases, when these two circumstances have not already decided the combat, therefore, particularly in case the destruction of the enemy’s force is the principal object, the decision is reached at that moment when the conqueror ceases to feel himself in a state of disintegration, that is, of unserviceableness to a certain extent, when therefore, there is no further advantage in using the successive efforts spoken of in the twelfth chapter of the third book. On this ground we have given the strategic unity of the battle its place here.

A battle, therefore, in which the assailant has not lost his condition of order and perfect efficiency at all, or, at least, only in a small part of his force, whilst the opposing forces are, more or less, disorganised throughout, is also not to be retrieved; and just as little if the enemy has recovered his efficiency.

The smaller, therefore, that part of a force is which has really been engaged, the greater that portion which as reserve has contributed to the result only by its presence, so much the less will any new force of the enemy wrest again the victory from our hands, and that commander who carries out to the furthest
