The baffles were later removed in 1918, and flying-off ramps were erected on "B" and "Q" turrets. After the war, the Grand Fleet was dissolved, and "Benbow" was assigned to the 4th Squadron of the Mediterranean Fleet, where she served until March 1926. In 1919, Captain Charles Douglas Carpendale took command of the ship, a position he held until 1921. During this period, from April 1919 to June 1920, the ship took part in anti-communist operations in the Black Sea. "Benbow" and other elements of the Mediterranean Fleet supported the White Russians in the Russian Civil War. In late January 1920, "Benbow" was sent from Constantinople to Novorossiysk. There, the ship relieved "Iron Duke", and shortly thereafter rescued a group of 150 Russian soldiers and their British adviser, who had been attacked by bandits. On 1 February, Rear Admiral Michael Culme-Seymour hoisted his flag aboard "Benbow". Shortly thereafter, men from the ship were sent to inspect White positions in the Kerch Peninsula. "Benbow" was ordered to return to Constantinople in June, where the Mediterranean Fleet was concentrating to begin supporting Greek forces during the Greco-Turkish War; she arrived there on 19 June. On 5 July, "Benbow" and several other vessels left Constantinople to land a force at Gemlik to secure the harbor in order to hand it over to Greek forces that would arrive later. "Benbow"s men returned to the ship on 16 July after a Greek battalion reached the town. In February 1921, "Benbow", the battleship , and several destroyers conducted training exercises in the Sea of Marmara. In 1922, the ship underwent a refit at Malta. In September and October that year, she took part in further operations against Turkish forces. On 1 November 1924, the 4th Squadron was renumbered as the 3rd Squadron. The 3rd Squadron was transferred to the Atlantic Fleet in March 1926 and remained there until September 1930. She became the squadron flagship on 12 May 1928, relieving "Iron Duke" for a major refit. "Benbow" took part in major fleet training exercises held in March 1929 in conjunction with the Mediterranean Fleet. Later that year, the ship was paid off. In September 1930, "Benbow" was placed on the sale list. Under the terms of the Washington Naval Treaty, "Benbow" and her sisters were slated to be replaced by new construction the following year.
