Fort Frye was a triangular-shaped defensive fortification built by a group of pioneers from the Ohio Company of Associates who moved about twenty miles up the Muskingum River from the settlement of Marietta , Ohio to a location near the mouth of Wolf Creek . During 1789 the pioneers established settlements now known as Waterford and Beverly on the southwest and northeast banks of the Muskingum , respectively . The settlements were located about 13 miles downriver from a small group of pioneers at Big Bottom . During January and February 1791 , following the massacre at Big Bottom and the start of the Northwest Indian War , the settlers built Fort Frye at Beverly
