Archeology In addition to reaching out to the public, the Delaware County Planning Department hired the Cultural Resource Management irm JMA, a CCRG Company, to conduct an Archeological Design Analysis for the Preservation Plan. The analysis was entirely research‐based and non‐ invasive. The Plan’s archeological section includes a geomorphic analysis of the battleield and an assessment of potential archeological remains. JMA relied on military terrain analysis to identify the boundaries of the Rearguard Defense and Strategic Retreat study areas. he plan includes in‐depth portrayals of ten deining T features, nine of which are illustrated on the map below. A battleield’s deining features are described by the American Battleield Preservation Program as: “...natural terrain features, manmade features, and place names found in battle descriptions or on historic maps that can be used to locate signiicant actions and The path of the Strategic Retreat events that associated with a battle. A deining feature relects the landscape in which the may be a place such as town or farm, a structure such as Americans withdrew along Thornton a mill, house or church, a road, wood lot, earthwork, or Road and Route 1, enabling them to farm ield: it may be a natural terrain feature, such as a rally in order to face the British stream, hill, ford, or ravine....

During the Rearguard Defense, Major General and his men formed a defensive line to stop the advancement of the British troops, thus allowing the Americans to more easily retreat. R T‐A
