How "free" is free riding in civil wars? Violence, insurgency, and the collective action problem

It had been by no means easy to flee into the mountains and to help set up what, both in my opinion and in that of friends little more experienced than myself, should have become a partisan band affiliated with the resistance movement Justice and Liberty.

We lacked capable men, and instead we were swamped by a deluge of outcasts, in good or bad faith, who came from the plain in search of a non-existent military, of political organization, of arms, or merely of protection, a hiding place, a fire, a pair of shoes.
