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. 115

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.
