"The characteristics of the struggle, in which territory had to be given to the enemy and many years had to pass in order to achieve final victory, with fluctuations, ebb and flow, was that of a protracted war. During the entire struggle one could say that the front lines were where the enemy was. At a given moment, the enemy occupied almost the entire territory and the front was spread to wherever the enemy was. Later the lines of combat were delimited and a main front was established. But the enemy's rear guard constituted another front; it was a total war and the colonialists were never able to mobilize their forces with ease against the liberated zones. The slogan "dynamism, initiative, mobility, and quick decision in new situations" is in synthesis the guerrilla tactic. These few words expressed the tremendously difficult art of popular war."
