Recovery of the remnants of the CSS Georgia in Savannah has yielded another archaeological treasure: A third Dahlgren gun.
It’s known that the Confederate ironclad, which was part of the Georgia city’s defenses, had at least 10 guns at some point – but no one knew exactly how many were on board when the vessel was scuttled in December 1864.
Two guns were found years ago and sit outside Old Fort Jackson nearby. A U.S. Navy diving team this summer salvaged four guns, including one 9,000-pound Dahlgren, two Brooke rifles and a smaller gun.
Now there’s a seventh gun. U.S. Army Corps of Engineers spokesman Russell Wicke said that the massive Dahlgren brought up Tuesday was a bit of a surprise because it apparently evaded earlier archaeological and sonar surveys because it was deeper in the muck. It was scooped up by a large grapple that went into use this week.
Jim Jobling, a project manager with Texas A&M University's Conservation Laboratory, theorized a second Dahlgren would be found, according to an Army Corps article. A wartime manifest of the ship didn't mention them.
