The captains had heard of John Hay in a letter William Henry Harrison dated 13 November 1803, in which the Illinois Governor mentions a map—owned by Hay—from the Mackay-Evans Expedition. Hay, a fur trader and Postmaster in Cahokia, later provided Lewis a copy of that expedition’s 1795–97 journey up the Missouri. He and fellow Cahokian Nicholas Jarrot also translated when Lewis met Spanish Governor of Upper Louisiana, Carlos Dehault Delassus in St. Louis. With his considerable experience with Native American Nations and the Missouri-Mississippi fur trade, Hay also provided the captains significant information and advice.
