The Battle of Seven Oaks was a violent confrontation between the Hudson's Bay Company (HBC) and the North West Company (NWC), rivals in the fur trade, that took place on 19 June 1816. It was the climax of a long dispute in western Canada.^[3] The Métis people, who fought for the North West Company, called it "the Victory of Frog Plain" (la Victoire de la Grenouillière).
