If you want to read a good true history of the Potawatomi, you got to read Gary Mitchell's "Stories of the Potawatomi"! When Gary wrote this book, there were no new books written about the Potawatomi since the late '60's.
Among the stories, he wrote about Potawatomi veterans, about their war experiences and how they coped with the sorrow of war when they came home! And that was long before it was really in: to honor vets like they do nowadays! I think this book is now out of print, but you can read the stories in the link above!
