Seal

A large mine-laying submarine, one of six in the Grampus class. From the earliest days of World War II, HMS Seal undertook diverse missions, including reconnaissance and escort duties. While operating in Scandinavian waters in May 1940, the submarine was damaged and avoided destruction thanks to the heroic efforts of her crew but was ultimately forced to surrender by a German aircraft.
