Flag 4 is the signal for 'attack with torpedoes'. In this authoritative and thrilling account of the actions of British motor torpedo boats in the Mediterranean during World War II, Dudley Pope uses eyewitness accounts of those who fought the many battles. Through assaults on enemy coastal convoys and clandestine operations, including operating with Special Boat Squadron units, the smallest ships in the navy helped keep the Mediterranean Sea open during the darker period of the war, and played a significant role in supporting various resistance movements and the eventual allied victories in North Africa and Southern Europe."
