A team of underwater archaeologists from the University of South Carolina, managed to raise three civil war cannons – each weighing upwards of 15000 pounds – from the bottom of the Great Pee Dee River in South Carolina near Florence, S.C.
Two of them were Confederate Brooke rifle cannons (11.8 and 12.25 feet each) and one was a captured Union Dahlgren cannon (8.9 feet). This trio was the complete artillery of the “CSS Pee Dee”, a 150-foot Macon-class Confederate gunboat built for patrolling waterways and protect the coast of South Carolina.
Just only three months after it was launched, the career of the CSS Pee Dee came to an end. On March 15, 1865, in response to U.S. Gen. William T. Sherman’s northward advance to North Carolina, fearing that the gunboat might fall into enemy hands, commanders ordered the cannons thrown overboard before the ship was set on fire and abandoned.
The team of archaeologists from the UofSC began searching for the CSS Pee Dee and its birth place – the Confederate Mars Bluff Navy Yard – back in march 2009.
Mars Bluff Navy Yard was one of seven Confederate naval yards. They were located inland so gunboats and support vessels for the war could be built and protected from U.S. forces.
