On the basis of the old documents and stories once Kenneth McKenzie had effect in Missouri,.
From early times, there had been a problem with the Indians and liquor. Kenneth McKenzie, the bourgeois at Ft. Union in 1833, found a way to circumvent the federal government’s laws on bringing liquor up the Missouri River for the Indians. In the spring of 1833 the steamer Yellowstone made its way up the Missouri with distillery equipment for the trade at Ft. Union. By July of 1833 the still was in full operation, producing moonshine whiskey from Indian corn purchased from the Mandan tribe. Eventually, one of the UMO's competitors "blew the whistle" on McKenzie, and he and Pierre Chouteau, Jr. were compelled to explain this breach of the intent of the anti liquor laws for the Indians. It is completely understandable why this happened, as HBC freely supplied liquor to the Indians with whom they traded, both to grease the wheels of commerce, and to tilt the balance in their favor. The Upper Missouri Outfit was just leveling the playing field. Other Missouri River traders also managed to get whiskey to the Indians, sometimes importing it from the New Mexico area
