Beginning in March 1915, the "London"-class ships began to be transferred to the Mediterranean Sea to participate in the Dardanelles Campaign; "London", "Queen", and "Prince of Wales" supported the Landing at Anzac Cove in April, but they were withdrawn in May to reinforce the Italian fleet blockading the main fleet of the Austro-Hungarian Navy in the Adriatic Sea. At the same time, "Venerable" was transferred to the Dardanelles, where she supported Allied troops ashore in August before also being sent to the Adriatic at the end of the year. "Queen" was converted into a depot ship in late 1916 and "London" and "Venerable" were withdrawn to Britain, where they were decommissioned and later converted into a minelayer and depot ship, respectively. "Prince of Wales" became a barracks ship in 1917. All four ships were ultimately sold for scrap in 1920 and broken up between 1920 and 1922.
