The Atlantic Ocean is a big body of water. One of the biggest. And within its watery coffers it hides many secrets and memories — some we’ll discover someday, some we never will.

According to marine archeologists off the coast of North Carolina Tuesday, you can officially chalk one up for humankind (and not the sea) recently, because they’re announcing that they discovered a super rare sunken ship resting on the cold ocean floor — an iron-hulled blockade runner from the 19th century that was once part of the Confederacy’s fleet in the Civil War.

Even more remarkable about the find is that its 225-feet long, more than 150 years old and mostly intact (shown above). Oh, and the boat even contains luxuries from its day, like fancy clothes from Paris, expensive booze and bourgeois books.

Researchers are speculating that the ship is the Agnes E. Fry, once of three blockade runners known to have been lost in the region.

During a routine sonar assessment of known wrecks off the seaside town of Oak Island in North Carolina on Feb. 27, researchers and archaeologists stumbled upon the well-preserved wreckage of a blockade runner steamer from the Civil War, according to Billy Ray Morris, North Carolina’s deputy state archaeologist-underwater and director of the North Carolina Department of Natural and Cultural Resources’ Underwater Archaeology branch.

He explained that the vessel was a blockade runner for the Confederacy during the Civil War. Blockade runners were “speedy steamers” used to get around Union war fleets, which sought to cut off the Confederacy from overseas trade.

“These were some of the most sophisticated ships of their day, comparable to the high-speed cigarette boats that modern-day drug smugglers might use now,” Morris said.

Morris said further dives and investigation will be performed in the coming days to officially identity the ship and find even more details/information about the historic relic.
