Charles Gratiot operated fur trade posts in Cahokia and Kaskaskia, Ill. He played a large role in supplying provisions to George Rogers Clark and his army. At the end of the Revolutionary War, he moved to St. Louis, where he continued in business. These letters include a description of the commercial assets of Louisiana, especially New Orleans; a discussion of business matters; and impressions of Anglo-American relations. The collection also includes a brief biographical sketch of Gratiot, prepared in 1966 by Jocelyn Ghent, and a photograph of a portrait of Gratiot.
