The Action off Noordhinder Bank on 1 May 1915 was a naval engagement between four British naval trawlers, supported by a flotilla of four destroyers and a pair of German torpedo-boats from the Flanders Flotilla. The action began when the two torpedo boats were sent to rescue the crew of a reconnaissance seaplane that had been forced to alight by engine-trouble and to attack the trawlers. The Germans engaged the trawlers; British destroyers from Harwich Force appeared and the German ships ran for home but were sunk.
