SAVANNAH, GEORGIA—A 5,000-pound-piece of the ironclad CSS Georgia has been removed from the Savannah River by U.S. Navy divers. Archaeologists will study the piece of the casemate before attempting to recover the rest of the warship, which was scuttled in 1864 by the Confederate Navy to keep it from the Union troops that were approaching Savannah. “Tuesday’s retrieval will play a major role in creating a research design to effectively remove the CSS Georgia before expanding the shipping channel along this stretch of the Savannah River,” said archaeologist Julie Morgan of the Army Corps of Engineers.
