All that is known of this Chippewa chief is Colonel McKenney's terse, stereotyped description: "He is six feet three inches in stature, and well made."

The Indian superintendent first met the chief at the Fond du Lac treaty council in the summer of 1826.

The appearance of the chief was a singular victory for McKenney and Michigan Governor Lewis Cass; both were aware of the long allegiance of the Rainy Lake Chippewa to the British. The close relationship of the tribe and the crown began with Anacamegishca's great grandfather, the famous Chippewa chief Nittum. (This is McKenney's spelling, but it may be the Chippewa nitam, meaning "the first").

His influence over the nation was so great that the North-West Fur Company wooed him for years with gifts of whiskey, rifles and powder in order to keep his friendship and maintain their monopoly of the fur trade. When the old man died the officials of the company ordered his burial platform elevated near the Grand Portage trading post in the northeastern corner of Michigan and the Union Jack flown nearby.

In 1803, when the post was abandoned for the new trading center Forth William on the northwest shore of Lake Superior, the chief's bones were removed with great ceremony, as McKenney recalled, and "honoured with distinguished marks of respect..."

The respect and trust with which the Indian nations of the frontier of the 1820s regarded Colonel McKenney and Governor Cass undoubtedly helped to influence the Chippewa to abandon the British for the Americans.
