It is always interesting to dive on wrecks. This can include wrecks of sunken warships, which can serve as an eerie glimpse into the past. Some ships, like the Essex-class aircraft carrier USS Oriskany (CV 34), are old warships being put to use as artificial reefs.
Others were sent to Davy Jone's Locker the hard way during the war. One such vessel is the German U-boat U-85. According to U-Boat.net, this sub sank three vessels during its wartime service before it ran into USS Roper (DD 147). The Roper put U-85 on the bottom of the Atlantic. All hands went down with the German sub less than twenty miles off the coast of North Carolina.
The story, though, doesn't end there. According to Outer Banks Sentinel's web site, in 2001, divers Jim Bunch, Roger Hunting, and Rich Hunting retrieved the sub's Enigma machine. The site claimed that Navy divers had attempted a similar objective shortly after the U-boat sank in 1942. The Sentinel noted that the Enigma was worth as much as $200,000, although appraisals supposedly for tax purposes were in the range of $50,000 to $75,000.
A 2003 release by the United States Navy's Naval Historical Center noted that "the retrieval of the Enigma machine by the private divers was illegal without proper authorization from the German government to do so." The Navy, the divers, and the German government later arranged for the Engima machine in question to be donated to the Atlantic Graveyard Museum, where it is today.
The looting of war graves has become an epidemic in the East Indies, including the battleship HMS Prince of Wales, the battlecruiser HMS Repulse, and a number of other allied vessels.
