HMS Centurion (1911) - Interwar, World War II

Interwar, World War II

With the signing of the Washington Naval Treaty Centurion was decommissioned and made a target ship to replace HMS Agamemnon in 1924. She remained in this role at Portsmouth Harbour until April 1941, where she was fitted with a false superstructure so as to resemble the battleship HMS Anson then building at HM Dockyard, Portsmouth.

On 4 April 1941, the Admiralty suggested that a heavy naval bombardment of the Libyan city of Tripoli should be made by the Mediterranean Fleet and followed up by blocking the port with a block ship, the Centurion. Admiral Andrew Cunningham declined the offer due to her slow speeds and heavy enemy air cover, so this idea was shelved.

In June 1942, she sailed with Operation Vigorous in the eastern Mediterranean to simulate an operational battleship. Between 1942 and 1944 Centurion was stationed off Suez as an anti-aircraft ship and to give pause to Regia Marina action in the area—the Italians thought that her false wooden 13.5-inch guns were real and kept their superdreadnoughts away. Her final act after a long and somewhat understated career was to be sunk as a breakwater off the Normandy beaches after D-Day. Reportedly the Germans thought that the old vessel had been sunk by shore batteries of the German 352nd Division with great loss of life when only 70 crewmen were observed leaving the sinking vessel; in fact the 70 men were the entire crew.
