UB-116 wreck dive, Scapa flow

During World War I, UB-116 was tasked with penetrating Scapa Flow and taking out as many ships as possible to even the odds for a last attack by the German High Seas Fleet. An earlier attempt to confront the British Grand Fleet and bring them to battle had been frustrated by the Kiel sailor mutiny.
The U-boat's captain Lieutenant JJ Emsmann had been advised to use Hoxa Sound as Royal Navy vessels had been seen, by other U-boats in the Pentland Firth, using this entrance to Scapa Flow.
The U-boat was spotted when Emsmann came to periscope depth at 11.30pm to check his position. The mines were detonated and UB-116 was destroyed. She was the last U-boat sunk in World War I.
She lies at 29m and is in the worst possible condition for a U Boat, although the plethora of life covering her, more than makes up for this. Swimming Ling and Conger plus all the usual subjects!
