HMS "Inflexible" was one of three s built for the Royal Navy before World War I and had an active career during the war. She tried to hunt down the German battlecruiser and the light cruiser in the Mediterranean Sea when war broke out and she and her sister ship sank the German armoured cruisers and during the Battle of the Falkland Islands. "Inflexible" bombarded Turkish forts in the Dardanelles in 1915, but was damaged by return fire and struck a mine while maneuvering. She had to be beached to prevent her from sinking, but she was patched up and sent to Malta, and then Gibraltar for more permanent repairs. Transferred to the Grand Fleet afterwards, she damaged the German battlecruiser during the Battle of Jutland in 1916 and watched "Invincible" explode. She was deemed obsolete after the war and was sold for scrap in 1921.
