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 whcih is accepted as infaillible. That rule says that an attacker should concentrate his forces in order to be stronger than his opponent and the moment of conflict.
Guerilla war (always successful, as history show) directly infringes that rule.
