paragraph: Three great battle cruisers had gone to the bottom--the _Queen Mary_, of 27,000 tons; the _Indefatigable_, of 18,750 tons, and the _Invincible_, of 17,250 tons.  Cruisers lost included the _Defense_, of 14,600 tons; the _Black Prince_; of 13,550 tons, and the _Warrior_, of 13,550 tons.  The giant battle cruiser _Marlborough,_ of 27,500 tons, had been badly damaged, as had the _Lion_ and other vessels.  The destroyers _Tipperary, Turbulent, Nestore, Alcaster, Fortune, Sparrow Hawk, Ardent_ and _Shark_ had been sunk.  Total losses ran high into the millions and in the number of men above 7,000.  The German losses had been less, but nevertheless, taking into consideration damage done to the effectiveness of the two fleets as a whole, the enemy had sustained the harder blow.  The British fleet still maintained control of the North Sea, while the Germans, because of their losses, had been deprived of a large part of the fighting strength of their fleet.  The British, in spite of their heavier losses, would recover more quickly than could the enemy. 
question: How many British ships were sunk, not merely lost or damaged?
answer: 11 (Queen Mary, Indefatigable, Invincible, Tipperary, Turbulent, Nestore, Alcaster, Fortune, Sparrow Hawk, Ardent, Shark)
