SM U-18 [Note 1] was one of 329 submarines serving in the Imperial German Navy in World War I. U-18 engaged in the commerce warfare in the First Battle of the Atlantic.
Beginning in October 1914, she was commanded by Kaptlt. von Hennig. [2]
On her third mission, on 23 November U-18 penetrated the fleet anchorage of Scapa Flow via Hoxa Sound, following a steamer through the boom and entering the anchorage with little difficulty. However, the fleet was absent, being dispersed in anchorages on the west coast of Scotland and Ireland. As U-18 was making her way back out through Hoxa Sound to the open sea, her periscope was spotted by a guard boat. The trawler Dorothy Gray altered course and rammed the periscope, rendering it unserviceable. U-18 then suffered a failure of her diving plane motor and the boat became unable to maintain her depth, at one point even impacting the seabed. She was rammed a second time by destroyer HMS Garry and eventually, her captain was forced to surface and scuttle his command just outside the Hoxa Gate; all crew members, except one, were picked up by British boats. [3] [4] One crew member perished, while the remaining 22 were interned as prisoners of war. [5]
The wreck lies 75 m (246 ft) below the surface just outside the Hoxa Gate, at 58°41′N 02°55′W / 58.683°N 2.917°W. [6]
