Nathan D. Champion — known as Nate Champion — was a key figure in the Johnson County War. Falsely accused by a wealthy Wyoming cattlemen's association of being a rustler, Champion was the first person targeted by a band of hit men hired by the wealthy cattle barons. In reality, Champion was simply a small rancher who stood up against the big cattlemen's practice of claiming all unbranded young cattle on the range. He is celebrated for his heroic stand in his besieged cabin and for a heartfelt letter written at the time describing the events.
