To halt Maj. Gen. McClellan's march up the peninsula toward Richmond, Confederate Maj. Gen. Magruder built three dams to create impassable lakes on the Warwick River and fortified the dams to prevent frontal assaults by Union forces during the 1862 Peninsula Campaign. This site is the first of those three dams and is the midpoint between two prewar tide mills at Lee's Mill and Wynne's Mill.
