We are interested in the other type, the case of an armed group engaged in struggle against the constituted power, whether colonial or not, which establishes itself as the only base and which builds itself up in rural areas. In all such cases, whatever the ideological aims that may inspire the fight, the economic aim is determined by the aspiration toward ownership of land.
The China of Mao begins as an outbreak of worker groups in the South, which is defeated and almost annihilated. It succeeds in establishing itself and begins its advance only when, after the long march from Yenan, it takes up its base in rural territories and makes agrarian reform its fundamental goal. The struggle of Ho Chi Minh is based in the rice-growing peasants, who are oppressed by the French colonial yoke; with this force it is going forward to the defeat of the colonialists. In both cases there is a framework of patriotic war against the Japanese invader, but the economic basis of a fight for the land has not disappeared. In the case of Algeria, the grand idea of Arab nationalism has its economic counterpart in the fact that nearly all of the arable land of Algeria is utilized by a million French settlers. In some countries, such as Puerto Rico, where the special conditions of the island have not permitted a guerrilla outbreak, the nationalist spirit, deeply wounded by the discrimination that is daily practiced, has as its basis the aspiration of the peasants (even though many of them are already a proletariat) to recover the land that the Yankee invader seized from them. This same central idea, though in different forms, inspired the small farmers, peasants, and slaves of the eastern estates of Cuba to close ranks and defend together the right to possess land during the thirty-year war of liberation.
Taking account of the possibilities of development of guerrilla warfare, which is transformed with the increase in the operating potential of the guerrilla band into a war of positions, this type of warfare, despite its special character, is to be considered as an embryo, a prelude, of the other. The possibilities of growth of the guerrilla band and of changes in the mode of fight, until conventional warfare is reached, are as great as the possibilities of defeating the enemy in each of the different battles, combats, or skirmishes that take place. Therefore, the fundamental principle is that no battle, combat, or skirmish is to be fought unless it will be won. There is a malevolent definition that says: "The guerrilla fighter is the Jesuit of warfare." By this is indicated a quality of secretiveness, of treachery, of surprise that is obviously an essential element of guerrilla warfare.
