Near Fort Peck in McCone County, Montana — The American West (Mountains)
"we do not wish to see those gentlemen"
Lewis & Clark at the Milk River
The Assiniboine have been present in the plains as early as the mid-1600s and were known to be along the Missouri River and in the Fort Peck area. The Assiniboine and Cree were the first of the western tribes to establish trading with the white men and distant tribes.
In 1804, while at Fort Mandan, Lewis and Clark met and learned about the Big Devil band of Assiniboines. They were reputed to be independent and fierce, and roamed the plains of what is now northeast Montana. Lewis and Clark had very little firsthand knowledge about the Assiniboine people, yet for the journey ahead of them through northeast Montana, they feared no other tribe as much as them. Although many signs of their presence were noted, Lewis and Clark passed through northeast Montana without a single recorded encounter.
"we saw where an Indian had recently grained, or taken the hair off of a goatskin; we do not wish to see those gentlemen just now as we presume they would most probably be the Assinniboins and might be troublesome to us. Capt C. could not be certain but thought he saw the smoke and some Indian lodges at a considerable distance up Milk river."
—Captain M. Lewis, May 8, 1805
"we sent out several hunters to scower the country, to this we were induced not so much from the want of provision as to discover the Indians whome we had reasons to believe were in the neighbourhood, from the circumstance of one of their dogs comeing to us this morning shortly after we landed; we still believe ourselves in the country usually hunted by the Assinniboins, and as they are a vicious illy disposed nation we think it best to be on our guard..."
—Captain M. Lewis, May 10, 1805
