Manuscript Collection: Knox Willett Letters

Collection Overview

Collection summary derived from "Guidebook to Manuscripts", 1969: Henry Knox (1750-1806), Secretary of War, and formerly a Revolutionary General, writes to Marinus Willett on July 3, 1790, about negotiations with the Creeks concerning treaties and agreements. Willett answers Knox on July12. Alexander McGillivray, the noted Creek Chief, is mentioned in both letters. Knox warns Willett about a Captain or Colonel Howard sent by the Spaniards to watch Chief McGillivray. Colonel Willett (1740-1830) served principally on the frontiers of New York in the campaigns against the Six Nations. It was in 1790 that he was sent by President Washington to treat with the Creek Indians at which he proved most successful.
