AI Summary

5 min read

In the autumn of 1808, two men paddled dugout canoes along the Jefferson River in present-day Montana, checking beaver traps in the heart of Blackfoot Country. They were John Colter and John Potts, both veterans of the Lewis and Clark expedition. When a noise startled them, Potts insisted it was buffalo. Colter warned it was the Blackfeet. Moments later, 500 to 600 warriors appeared on both banks. Potts refused to surrender, shot a warrior dead, and was immediately pierced with so many arrows that he looked "like a pin cushion." His body was hacked to pieces. The relatives of the dead warrior wanted to do the same to Colter, but the chiefs held a council. When they finished, one of them motioned toward the open prairie and said, "Go, go away." What followed—John Colter sprinting naked across cactus-covered prairie while being hunted by Blackfoot warriors—became one of the most famous survival stories of the American frontier.
