On November 4, 1791, the US Army, under the command of Major General Arthur St. Clair, suffered a major defeat. Expanding previous accounts, an Indiana historian/librarian includes a more complete roster of the units that fought against the Miami Indians on the banks of the upper Wabash River, a history of the tribe and the formation of the new US army. Lytle implies that, due to intentional as well as accidental destruction of records, the fate of every participant in the campaign may never be known. The roster and related Army details comprise about two-thirds of the book.
