During the war of 1812, many Ojibwe fought on the side of the British, but some were partial to the Americans. This left many hard feelings between bands which often spilled over into long-lasting grudges and violence.
During a particularly heated discussion between some of the Ojibwe at a trading post near Sault Ste Marie, the great warrior Muk-a-dishib, or the Black Duck, was passionately arguing for why the American cause was the superior one. His argument was rebutted by an Ojibwe from Canada who boasted about how many American scalps he had taken.
This did not sit well with Black Duck, and he arose, reminded the Canadian Ojibwe that the British had lost the war; the he raised his tomahawk, approached the braggart crying, "Those that you killed were my friends, you shall kill no more", and in a flash he drove his point home with his hatchet, splitting the man's skull open!
Following this breach of peace, Black Duck sought refuge with the Americans at their fort, and although his life was forfeit under Indian custom, General Cass bought his liberty with forty quarts of whiskey.
