When a Cree and Assiniboine war party launched a surprise attack upon tribes of the Blackfoot confederacy in October 1870, a major battle erupted in territory now within and adjacent to the City of Lethbridge. Overwhelmed by the combined strength and superior weapons of Blackfoot, Blood and Peigan, the attackers attempted to withdraw but only shattered remnants of the initial war party escaped the vengeance of pursuing warriors. Although minor skirmishes between Indian nations continued for some years, this engagement of 1870 was the last great inter-tribal battle to be fought in North America. *Note: This designation has been identified for review.
