Is there any "proof" of this horrid betrayal that Etienne was accused of? Other than accusations made by a man who convinced Champlain that Etienne was bad for his own gain?
After everything Etienne did for Champlain - he chose to believe a concocted story, banish Etienne, mark him a traitor, and force him to live with the natives (or be hung) never to be able to return to his homeland.
Something is amiss
