The Metis ignore the US Government to Hunt & fight the Sioux
In 1844, Amos J. Bruce, Superintendent of the Iowa Agency wrote to the Secretary of Indian Affairs to complain about the Red River Metis, who were ignoring the boundary and hunting in the United States. In addition to their large hunts, the Metis were fighting against the Dakota Sioux and ignoring calls to return to Canadian territory.
"It becomes my duty to call the attention of the Government to the fact that the half-breeds of Red River make regular incursions into the Sioux country far within our boundary, and slaughter annually vast numbers of buffalo; the number yearly killed by those people of these animals within our territory cannot be less than 30,000. The supplies of the British Hudson Bay Company post are drawn from this source principally, buffalo flesh dried and tallow being sent in large quantities inland for that purpose."
"Our Government, I think, should see that the rights of the Indians under their protection are not infringed upon. These half-breeds have not the least shadow of a claim to hunt upon the Sioux country, but, on the contrary, subject themselves to the penalty affixed by law to be inflicted upon all foreigners illegally in the Indian country."
"They come to hunt in large bands, well armed, and in too much force to fear the Sioux; and as to the threatened interference of our Government, they laugh at the idea. The consequence of such a state of things is, that quarrels are constantly occurring between the half-breeds and the Sioux Indians, attended, some times, with fatal effects. I have advice of a fight which took place a few days since, between these people, at least 150 miles within our boundary. It appears that a half-breed Chippewa of Red River was killed by a party of Yanktons, of the Missouri, which was retaliated by a large party of half-breeds upon another band of Sioux, (belonging to Lake Traverse) who had no cognizance of the affair, and who were attacked by the half-breeds without any warning, and eight Sioux were killed and two taken prisoners."
