Nothing was heard from her following her departure from Portsmouth on 7 November 1940 with 40 crew on board to relieve HMS Usk which was on patrol off the Western Approaches near Brest, France. At the time it was thought that she had been sunk by a German destroyer. However she was discovered by a local diver in 1983, split into two just forward of the gun by a mine. The wreck lies in about 46 metres of water roughly 12 miles south of St. Catherine’s Point, Isle of Wight. It is likely that she struck the mine shortly after sailing whilst carrying out a trim dive. The wreck site is designated as a protected place under the Protection of Military Remains Act 1986.
