 As the guerrillas establish control in given areas, a supply chain must be established to satisfy all of the force's needs, particularly food, salt, and leather for shoes.Peasant farmers can give a portion of their work product to the guerrillas, and supply caches should be stored throughout the countryside.Mules are excellent beasts of burden for guerrilla needs, both because they can shoulder heavy loads, and also because they can traverse the rough ground which is the guerrilla's native territory.
