“Captives were made to consume pieces of their own flesh.”
The captors would also eat their prey; cannibalism was rampant in the tribal wars in the Hudson Valley.
I remember reading somewhere that “Mohawk” (Iroquois Confederation tribe) was a Leni Lenape (Delaware) word for man-eater. The word “Mohawk” which we and now they refer to themselves is the mangled attempt by English speakers to say the Leni Lanape word.
