Hugh Glass

In 1823, American fur trapper Hugh Glass was attacked by a grizzly bear during his exploration of the Upper Missouri River. After being thrown to the ground by the bear, he got up and repeatedly stabbed the bear with his knife until it died. He was left for dead 200 miles from the nearest settlement. He had a broken leg, cuts exposing his bare ribs, and festering wounds. He regained consciousness, set his leg, used maggots to eat his dead flesh, and crawled his way back to civilization over 6 weeks. He survived on roots, berries, and even chased wolves away from a bison carcass. When he returned home, he got his rifle back and continued his work as a trapper.
