Operation Fuller is more commonly known as the Channel Dash of World War II. In February 1942 the German battleships Gneisenau and Scharnhorst plus the cruiser Prinz Eugen were ordered to sail from Brest through the Dover Strait to the Baltic escorted by many warships and aircraft. Thick fog meant that they were spotted late. Cross Channel guns were unsighted and Motor Torpedo Boats could not get near enough. Fleet Air Arm and RAF aircraft attacked but failed to stop the German fleet. 42 British and 18 German planes were lost in the battle.
