From 1850 to 1854, fur trader and interpreter Joseph Bissonette ran an independent trading post on the North Platte River, serving emigrants and Lakota bands alike. He later worked as a ferryman, bridge partner, and government official through the Oregon Trail’s final violent years.
Fort Bernard undercut Fort John’s prices by up to 40% in 1845–46, until a fire destroyed it within two years. Visited by Francis Parkman and the Donner Party, it captures a fierce, short-lived challenge to the American Fur Company’s monopoly on the North Platte.
