It will not be proper to pass over in silence the fate of the unfortunate men taken prisoners in this affair. After night had set in, several Canadians came to the fort, bringing vague and awful reports of the scenes that had been enacted at the Indian camp. The soldiers gathered round them, and, frozen with horror, listened to the appalling narrative. A cloud of deep gloom sank down upon the garrison, and none could help reflecting how thin and frail a barrier protected them from a similar fate. On the following day, and for several succeeding days, they beheld frightful confirmation of the rumors they had heard. Naked corpses, gashed with knives and scorched with fire, floated down on the pure waters of the Detroit, whose fish came up to nibble at the clotted blood that clung to their ghastly faces.
"The Indians, fearing that the other barges might escape as the first had done, changed their plan of going to the camp. They landed their prisoners, tied them, and conducted them by land to the Ottawas village, and then crossed them to Pondiac's camp, where they were all butchered. As soon as the canoes reached the shore, the barbarians landed their prisoners, one after the other, on the beach. They made them strip themselves, and then sent arrows into different parts of their bodies. These unfortunate men wished sometimes to throw themselves on the ground to avoid the arrows; but they were beaten with sticks and forced to stand up until they fell dead; after which those who had not fired fell upon their bodies, cut them in pieces, cooked, and ate them. On others they exercised different modes of torment by cutting their flesh with flints, and piercing them with lances. They would then cut their feet and hands off, and leave them weltering in their blood till they were dead. Others were fastened to stakes, and children employed in burning them with a slow fire. No kind of torment was left untried by these Indians. Some of the bodies were left on shore; others were thrown into the river. Even the women assisted their husbands in torturing their victims. They slitted them with their knives, and mangled them in various ways. There were, however, a few whose lives were saved, being adopted to serve as slaves." - Pontiac MS.
