"In individual terms, I found being a guerrilla behind enemy lines considerably better than being a platoon leader in Merrill’s Marauders ... where I was told to lead my men straight into dug-in machine guns. Your only hope was that one or two men would still be on their feet when they got close enough to the pillbox to throw a grenade. In such circumstances, an infantry platoon leader could do almost nothing to influence the situation. His brains and skill were essentially irrelevant. The only thing that counted was his luck."

"A guerrilla leader, on the other hand, could match his wits against the enemy’s. If he was careful about gathering intelligence, perceptive in analyzing it, and knowledgeable about the tactics and strategy of guerrilla operations, he could do a great deal of damage to the enemy and at the same time minimize the risk to his own men."

"A guerrilla leader can be successful only in very special circumstances. For us, the circumstances had not been perfect, but they had certainly been good. First and foremost is terrain. Guerrillas need cover to operate effectively—mountains, forest, or jungle. ... On mountain and jungle trails, guerrillas on foot are as mobile as a motorized enemy. It was the terrain that made it possible for us to find safety in constant movement, rarely spending two nights in the same place."
