The invention of gunpowder and the constant improvement of firearms are enough in themselves to show that the advance of civilization has done nothin… - Carl von Clausewitz

Surprise becomes effective when we suddenly face the enemy at one point with far more troops than he expected. This type of numerical superiority is quite distinct from numerical superiority in general: it is the most powerful medium in the art of war.

PRINCIPLE is likewise such a law for action, except that it has not the formal definite meaning, but is only the spirit and sense of law in order to leave the judgment more freedom of application when the diversity of the real world cannot be laid hold of under the definite form of a law.

We propose to consider first the single elements of our subject, then each branch of part, and, last of all, the whole in all its relations-therefore to advance from the simple to the complex. But it is necessary for us to commence with a glance at the nature of the whole, because it is particularly necessary that in the consideration of any of the parts their relation to the whole be kept constantly in view.

We shall not enter into any of the abstruse definitions of War used by publicists. We shall keep to the element of the thing itself, to a duel. War is nothing but a duel on an extensive scale. If we would conceive as a unit the countless number of duels which make up a War, we shall do so best by supposing to ourselves two wrestlers. Each strives by physical force to compel the other to submit to his will: each endeavors to throw his adversary, and thus render him incapable of further resistance.

War therefore is an act of violence intended to compel our opponent to fulfill our will.
