passage 158 of 539 · BOOK I. ON THE NATURE OF WAR > CHAPTER IV. The Combat in General (*continuation*) (4/5)

in brief
He says victory has three elements—greater enemy loss in physical power, in moral power, and the enemy’s relinquishment of intentions—while emphasizing secure retreat lines and the moral/public impact.

its appearance, and then it certainly casts a lustre on the Army and its Leader, but it can then do nothing more by its moral influence for events long past.

If prisoners and captured guns are those things by which the victory principally gains substance, its true crystallisations, then the plan of the battle should have those things specially in view; the destruction of the enemy by death and wounds appears here merely as a means to an end.

How far this may influence the dispositions in the battle is not an affair of Strategy, but the decision to fight the battle is in intimate connection with it, as is shown by the direction given to our forces, and their general grouping, whether we threaten the enemy’s flank or rear, or he threatens ours. On this point, the number of prisoners and captured guns depends very much, and it is a point which, in many cases, tactics alone cannot satisfy, particularly if the strategic relations are too much in opposition to it.

The risk of having to fight on two sides, and the still more dangerous position of having no line of retreat left open, paralyse the movements and the power of resistance; further, in case of defeat, they increase the loss, often raising it to its extreme point, that is, to destruction. Therefore, the rear being endangered makes defeat more probable, and, at the same time, more decisive.

From this arises, in the whole conduct of the War, especially in great and small combats, a perfect instinct to secure our own line of retreat and to seize that of the enemy; this follows from the conception of victory, which, as we have seen, is something beyond mere slaughter.

In this effort we see, therefore, the first immediate purpose in the combat, and one which is quite universal. No combat is imaginable in which this effort, either in its double or single form, does not go hand in hand with the plain and simple stroke of force. Even the smallest troop will not throw itself upon its enemy without thinking of its line of retreat, and, in most cases, it will have an eye upon that of the enemy also.

We should have to digress to show how often this instinct is prevented from going the direct road, how often it must yield to the difficulties arising from more important considerations: we shall, therefore, rest contented with affirming it to be a general natural law of the combat.

It is, therefore, active; presses everywhere with its natural weight, and so becomes the pivot on which almost all tactical and strategic manœuvres turn.

If we now take a look at the conception of victory as a whole, we find in it three elements:—

  1. The greater loss of the enemy in physical power.

  2. In moral power.

  3. His open avowal of this by the relinquishment of his intentions.

The returns made up on each side of losses in killed and wounded, are never exact, seldom truthful, and in most cases, full of intentional misrepresentations. Even the statement of the number of trophies is seldom to be quite depended on; consequently, when it is not considerable it may also cast a doubt even on the reality of the victory. Of the loss in moral forces there is no reliable measure, except in the trophies: therefore, in many cases, the giving up the contest is the only real evidence of the victory. It is, therefore, to be regarded as a confession of inferiority—as the lowering of the flag, by which, in this particular instance, right and superiority are conceded to the enemy, and this degree of humiliation and disgrace, which, however, must be distinguished from all the other moral consequences of the loss of equilibrium, is an essential part of the victory. It is this part alone which acts upon the public opinion outside the Army, upon the people and the Government in both belligerent States, and upon all others in any way concerned.
