From the January 9, 2017, Wilmington Star-News (NC) "Fort Fisher cannon gets face lift in time for January 14 anniversary" by Ben Steelman.
The 32-pounder cannon on Shepherd's Battery has been restored in time for the 152 anniversary of the Second Battle of Fort Fisher. The 30-year-old reproduction of a Civil War era coastal artillery piece is a big favorite of visitors to the fort and fired during re-enactments, the boom of it supposedly can be heard all the way in Wilmington.
However, exposure to salt air and the elements over the years necessitated the work.
The Friends of Fort Fisher, to which I belong, raised $25,000 for it and were aided by a $6,000 grant from the Society of the Order of the Southern Cross (a Confederate heritage, a non profit group working to restore all things Civil War).
