The Battle of Seven Oaks—also known as the Seven Oaks Massacre and the Seven Oaks Incident—was a violent confrontation of the Pemmican War between the Hudson's Bay Company (HBC) and the North West Company (NWC) which occurred on 19 June 1816 near modern-day Winnipeg, Manitoba.
Resulting in a decisive victory for the NWC over their rivals in the North American fur trade, the confrontation was the climax in a long series of dispute in the Canadas.
The battle is also known as the Victory of the Frog Plain (French: la Victoire de la Grenouillère) among Métis People, whose members fought for the NWC during the battle. The event would mark one of the first times the Métis asserted themselves as la Nouvelle Nation ('the New Nation') and fly the flag of the Métis Nation.
