The prisoners were “walking ghosts”: “pale and disfigured, attacked by vermin who were spread over all parts of our bodies, covered with blood and dust.” But they were treated more kindly from then on. As they marched some insurgents dismounted from their horses and let the exhausted prisoners ride. At the next camp, where the insurgents’ salle du gouvernement—the central seat of the insurgent government—was located, they were greeted by a man named Jean-Louis, a domestic slave who had lived for several years in France and for this reason was nicknamed “the Parisian.” He fed them and provided them with “an excellent mattress,” and they rested well. — Dubois, Laurent, Avengers of the New World_ The Story of…, 418
