High Quality Content by WIKIPEDIA articles! HMS Grafton (H89) was a G-class destroyer built for the Royal Navy during the mid-1930s. During the Spanish Civil War of 1936–1939 the ship spent considerable time in Spanish waters, enforcing the arms blockade imposed by Britain and France on both sides of the conflict. After the beginning of World War II she was transferred from the Mediterranean Fleet to Great Britain for escort and contraband inspection duties. Grafton was refitting when the Norwegian Campaign began in April 1940, but the ship escorted convoys to Norway once her refit was completed. She evacuated British troops from the Dunkirk bridgehead in May, but was sunk by a German submarine after she stopped to rescue survivors from another British destroyer.
