Experience shows that transmission by word of mouth greatly distorts any communication.
For these same reasons, manufacture will have much less importance, at the same time that it would be much more difficult to carry it out. It will not be possible to have factories making shoes or arms. Practically speaking, manufacture will have to be limited to small shops, carefully hidden, where shotgun shells can be recharged and mines, simple grenades, and other minimum necessities of the moment manufactured. On the other hand, it is possible to make use of all the friendly shops of the zone for such work as is necessary.
This brings us to two consequences that flow logically from what has been said. One of them is that the favorable conditions for establishing a permanent camp in guerrilla warfare are inverse to the degree of productive development of a place. All favorable conditions, all facilities of life normally induce men to settle; but for the guerrilla band the opposite is the case. The more facilities there are for social life, the more nomadic, the more uncertain the life of the guerrilla fighter. These really are the results of one and the same principle. The title of this section is "Warfare on Unfavorable Ground," because everything that is favorable to human life, communications, urban and semiurban concentrations of large numbers of people, land easily worked by machine: all these place the guerrilla fighter in a disadvantageous situation.
The second conclusion is that if guerrilla fighting must include the extremely important factor of work on the masses, this work is even more important in the unfavorable zones, where a single enemy attack can produce a catastrophe. Indoctrination should be continuous, and so should be the struggle for unity of the workers, of the peasants, and of other social classes that live in the zone, in order to achieve toward the guerrilla fighters a maximum homogeneity of attitude. This task with the masses, this constant work at the huge problem of relations of the guerrilla band with the inhabitants of the zone, must also govern the attitude to be taken toward the case of an individual recalcitrant enemy soldier: he should be eliminated without hesitation when he is dangerous. In this respect the guerrilla band must be drastic. Enemies cannot be permitted to exist within the zone of operations in places that offer no security.
