difficulty,1 Fort Clifton was considered to be one of the exceptions. The defenses around the fort consisted of an eight mile semi-circle facing the Appomattox River, with two battery emplacements (18 artillery pieces total) placed along a northwest-southeast axis.
The fort was shelled multiple times by Union gunboats in the Appomattox River in 1964: May 9th, June 10th, and June 16th. The fort's artillery was able to cripple one of the five gunboats participating in the May 9th attack. The documentation of the conflict over the fort is inconclusive when it comes to determining whether the fort was taken or held before the war's end.
Fort Clifton is long gone, leaving only archaeological remains to tell the story. The land it used to sit on is now a park and visitors can walk through the old earthworks. It was added to the National Register of Historic Places in 1981.
