This composite of two maps produced at the end of the Civil War shows most of the Confederate earthworks constructed during the war, as well as the bridge and causeways connecting Isle of Hope with Skidaway Island, via Long Island. The Confederate causeway across Jones Narrows has been added from other sources. The locations of Parkersburg and Wimberly, as labeled, are incorrect. The map also illustrates the large Confederate batteries at Thunderbolt and Beaulieu to the north and south of Isle of Hope, the locations of observation towers and telegraph lines, and the locations of Confederate salt works in the vicinity.
