Leo Tolstoy: War and Peace

BOOK FOURTEEN: 1812 2. CHAPTER II

One of the most obvious and advantageous departures from the so-called laws of war is the action of scattered groups against men pressed together in a mass. Such action always occurs in wars that take on a national character. In such actions, instead of two crowds opposing each other, the men disperse, attack singly, run away when attacked by stronger forces, but again attack when opportunity offers. This was done by the guerrillas in Spain, by the mountain tribes in the Caucasus, and by the Russians in 1812.

People have called this kind of war "guerrilla warfare" and assume that by so calling it they have explained its meaning. But such a war does not fit in under any rule and is directly opposed to a well-known rule of tactics which is accepted as infallible. That rule says that an attacker should concentrate his forces in order to be stronger than his opponent at the moment of conflict.

Guerrilla war (always successful, as history shows) directly infringes that rule.

This contradiction arises from the fact that military science assumes the strength of an army to be identical with its numbers. Military science says that the more troops the greater the strength. Les gros bataillons ont toujours raison.*

*Large battalions are always victorious.

For military science to say this is like defining momentum in mechanics by reference to the mass only: stating that momenta are equal or unequal to each other simply because the masses involved are equal or unequal.

Momentum (quantity of motion) is the product of mass and velocity.

In military affairs the strength of an army is the product of its mass and some unknown x.

Military science, seeing in history innumerable instances of the fact that the size of any army does not coincide with its strength and that small detachments defeat larger ones, obscurely admits the existence of this unknown factor and tries to discover it- now in a geometric formation, now in the equipment employed, now, and most usually, in the genius of the commanders. But the assignment of these various meanings to the factor does not yield results which accord with the historic facts.
