Reading edition
Cushing to Lieutenant-colonel Kingsbury, February 20, 1805. This letter belongs to the collection of letter books, letters, and other papers of Jacob Kingsbury in the Chicago Historical Society library. Kingsbury was in command of Detroit, Mackinac, and other northwestern posts from 1804 on, and for a time was the superior authority in charge of a group of posts including Fort Wayne, Fort Dearborn, Mackinac, and Detroit. His letters and papers constitute a source of prime importance for this period of northwestern history. They will be cited henceforth as the Kingsbury Papers.
