Stockade "G. Turner, “Plan and Elevation of a Stockade Work, with Block-House Bastions; designed for the defence of the Settlement of Coleraine, on the Great Miami River, 1791.” Watercolor, pen and ink. Josiah Harmar Papers. Map Division, Small Maps 1791.

This proposal for a fort to protect the settlement of Coleraine on Ohio’s Miami River employs a ground plan that would become increasingly popular on the 19th-century frontier.  A square stockade with bastions or blockhouses only on two opposite corners was economical of the number of defenders needed and still provided adequate flanking fire in a small fortification.  The combination blockhouse-bastions are of uncommon design.  The buildings provided quarters for officers and men."
