A 'Large America' flying boat flown by Flight Sub-Lieutenant C.R. Morrish, Royal Naval Air Service, on a 'Spider Web' patrol from Felixstowe sighted and attacked the German submarine
UC-36 on the surface near the North Hinder Light Ship. Destruction of the submarine was confirmed in January 1919. Another source claims: two other attacks during May. But
UC-36 actually lost on May 17 or 18 off Isle of Wight, probably to mine.
