Governor of the Hudson's Bay Company's Red River Colony in Canada from 1815 until his death at the Seven Oaks massacre in June 1816. Extremely rare ALS signed “Rob't Semple,” one page, 8 x 9.75, March 20, 1815. Letter to his uncle, in part: "I have directed the inclosed letter to your care and left it open for your perusal." In very good condition, with creasing, toning, staining, some short edge tears, and red wax seal remnants to left side. Semple is a legendary figure, and his letters are practically impossible to find.
