Pierre Dorion Jr. (1782[1]–1814) was a Métis fur trapper and interpreter who worked across the modern Midwestern United States and later the Pacific Northwest.
[4] In 1809, Manuel Lisa hired Dorion for his services as an interpreter and "conducted their traders in safety through the different tribes of the Sioux.
Early into the travel north where the PFC wintering camp was located, Dorion physically abused his wife and caused her to flee for a day.
Assurances were given that the expedition wouldn't trade with the neighboring Arikara, Mandan and the Gros Ventre nations, all three of whom the Sioux were at war with.
Early in 1814, Dorion, Reed and five other trappers were killed by a band of either Northern Shoshone[14] or Bannocks[15] His wife and two children then began their celebrated journey back to the safety of Pacific Fur Company posts.
