He who only knows War from books or the drill-ground cannot realise the whole effect of this counterpoise in action; WE BEG HIM, THEREFORE, TO ACCEPT FROM US ON FAITH AND TRUST ALL THAT HE IS UNABLE TO SUPPLY FROM ANY PERSONAL EXPERIENCES OF HIS OWN.
This illustration is intended to give more clearness to the course of our ideas, and in closing this chapter we will only briefly observe that in our exposition of Strategy we shall describe those separate subjects which appear to us the most important, whether of a moral or material nature; then proceed from the simple to the complex, and conclude with the inner connection of the whole act of War, in other words, with the plan for a War or campaign.
OBSERVATION.
In an earlier manuscript of the second book are the following passages endorsed by the author himself to be used for the first Chapter of the second Book: the projected revision of that chapter not having been made, the passages referred to are introduced here in full.
By the mere assemblage of armed forces at a particular point, a battle there becomes possible, but does not always take place.

Is that possibility now to be regarded as a reality and therefore an effective thing?
Certainly, it is so by its results, and these effects, whatever they may be, can never fail.

POSSIBLE COMBATS ARE ON ACCOUNT OF THEIR RESULTS TO BE LOOKED UPON AS REAL ONES.
If a detachment is sent away to cut off the retreat of a flying enemy, and the enemy surrenders in consequence without further resistance, still it is through the combat which is offered to him by this detachment sent after him that he is brought to his decision.
If a part of our Army occupies an enemy's province which was undefended, and thus deprives the enemy of very considerable means of keeping up the strength of his Army, it is entirely through the battle which our detached body gives the enemy to expect, in case he seeks to recover the lost province, that we remain in possession of the same.
In both cases, therefore, the mere possibility of a battle has produced results, and is therefore to be classed amongst actual events.

Suppose that in these cases the enemy has opposed our troops with others superior in force, and thus forced ours to give up their object without a combat, then certainly our plan has failed, but the battle which we offered at (either of) those points has not on that account been without effect, for it attracted the enemy's forces to that point.

And in case our whole undertaking has done us harm, it cannot be said that these positions, these possible battles, have been attended with no results; their effects, then, are similar to those of a lost battle.
In this manner we see that the destruction of the enemy's military forces, the overthrow of the enemy's power, is only to be done through the effect of a battle, whether it be that it actually takes place, or that it is merely offered, and not accepted.
