It ought to be noted by those who maintain dogmatically that the struggle of the masses is centered in city movements, entirely forgetting the immense participation of the country people in the life of all the underdeveloped parts of America. Of course, the struggles of the city masses of organized workers should not be underrated; but their real possibilities of engaging in armed struggle must be carefully analyzed where the guarantees which customarily adorn our constitutions are suspended or ignored. In these conditions the illegal workers' movements face enormous dangers. They must function secretly without arms. The situation in the open country is not so difficult. There, in places beyond the reach of the repressive forces, the inhabitants can be supported by the armed guerrillas. We will later make a careful analysis of these three conclusions that stand out in the Cuban revolutionary experience. We empha- size them now at the beginning of this work as our fundamental contribution.
Guerrilla warfare, the basis of the struggle of a people to redeem itself, has diverse characteristics, different facets, even though the essential will for liberation remains the same. It is obvious-and writers on the theme have said it many times-that war responds to a certain series of scientific laws; whoever ignores them will go down to defeat. Guerrilla warfare as a phase of war must be ruled by all of these; but besides, because of its special aspects, a series of corollary laws must also be recognized in order to carry it forward. Though geographical and social conditions in each country determine the mode and particular forms that guerrilla warfare will take, there are general laws that hold for all fighting of this type.
Our task at the moment is to find the basic principles of this kind of fighting and the rules to be followed by peoples seeking liberation; to develop theory from facts; to generalize and give structure to our experience for the profit of others.
Let us first consider the question: Who are the combatants in guerrilla warfare? On one side we have a group composed of the oppressor and his agents, the professional army, well armed and disciplined, in many cases receiving foreign help as well as the help of the bureaucracy in the employ of the oppressor. On the other side are the people of the nation or region involved. It is important to emphasize that guerrilla warfare is a war of the masses, a war of the people. The guerrilla band is an armed nucleus, the fighting vanguard of the people. It draws its great force from the mass of the people themselves. The guerrilla band is not to be considered inferior to the army against which it fights simply because it is inferior in firepower.
