The pursuit of Bismarck provides a practical example of destroyers threatening a battleship. Four attacked during the night while another remained in reserve. A joking literary exception imagines one especially aggressive Tribal-class destroyer managing alone despite the size disparity. The historical example relies on numbers, darkness, and repeated torpedo attacks to impose risk on a capital ship.
