If this is well done with competent agents the insurgent camp will be able to sleep more quietly.

This intelligence will be concerned principally, as I have already said, with the front line of fire or the forward enemy encampments that are in contact with no man's land; but it ought also to develop in the same measure as the guerrilla band develops, increasing its depth of operation and its potential to foresee larger troop movements in the enemy rear. Though all inhabitants are intelligence agents for the guerrilla band in the places where it is dominant or makes incursions, it is wise to have persons especially assigned to this duty. The peasants, not accustomed to precise battle language, have a strong tendency to exaggerate, so their reports must be checked. As the spontaneous forms of popular collaboration are molded and organized, it is possible to use the intelligence apparatus not only as an extremely important auxiliary but also as a weapon of attack by using its personnel, for example, as "sowers of fear." Pretending to be on the side of the enemy soldiers, they sow fear and instability by spreading discouraging information. By knowing exactly the places where the enemy troop is going to attack, it is easy to avoid him or, when the time is ripe, to attack him at places where it is least expected. Mobility, the basic tactic, can be developed to the maximum.
