The Real Story Behind The Revenant: What Hugh Glass Actually Endured

The Bear Attack: What Actually Happened

The bear attack was witnessed by several members of Glass's trapping party. The grizzly charged Glass from close range, knocking him to the ground before he could fire his rifle. Glass fought back with his knife, stabbing the bear repeatedly while it raked his body with its claws. The bear was eventually killed by other members of the party. Glass was found with his scalp mostly detached, his ribs exposed through torn flesh, and his throat punctured so badly that air was visible escaping through the wound.

The decision to leave Glass behind was made by the expedition leader, General William Henry Ashley, who believed Glass could not survive the night. Two men — John Fitzgerald and a young man often identified as Jim Bridger — were assigned to stay with Glass until he died and then bury him. Fitzgerald, fearing an Arikara attack, convinced Bridger to abandon Glass after three days. They took his rifle, his knife, and his flint, and left him to die alone. They reported to Ashley that Glass was dead.

The 200-Mile Crawl

Glass set his own broken leg, wrapped himself in the bear hide Fitzgerald had left covering him, and began crawling toward Fort Kiowa, more than 200 miles away. He navigated using the stars and the river, surviving on wild berries, edible roots, and the meat of a buffalo calf he managed to scare away from the wolves that had killed it. At one point, he reportedly used maggots to eat the dead flesh from his wounds, preventing gangrene.

The journey took six weeks. When Glass finally arrived at Fort Kiowa, the men there did not recognize him. He had lost most of his body weight, his wounds were partially healed but permanently disfiguring, and he had been presumed dead for over a month. His first words were to ask where Fitzgerald was.

The Revenge That Never Happened

This is where the film and history diverge most dramatically. In the film, Glass tracks Fitzgerald across the wilderness and engages him in a brutal, extended fight on a frozen riverbank. In reality, Glass found Fitzgerald, who had joined the United States Army, which made killing him a capital offense. Glass chose not to kill Fitzgerald. He took his rifle back and told Fitzgerald that if he ever deserted the Army, Glass would find him and kill him. But he never did.

Glass continued working as a fur trapper for another decade. He was killed in 1833, not by a grizzly, not in an act of revenge, but in a skirmish with Arikara warriors along the Yellowstone River. He was approximately 50 years old. The man who survived the impossible was brought down by something entirely ordinary.

What the Film Invents

The film invents the son, Hawk, who is killed by Fitzgerald — a narrative device to give Glass a motivation for revenge beyond the abandonment itself. The real Glass had no known son. The film also invents the extended revenge plot and the final confrontation. Glass's story, as recorded in the journals of the time, is about survival, not retaliation.

Hugh Glass was not a mythic avenger. He was a man who endured something no human should survive, and then let go of the anger that could have consumed the rest of his life. The film took the survival and added the revenge. The real story is quieter and, in its own way, more extraordinary.
