The Black Sea and Caspian Squadron,[1] also known as the Black Sea and Marmora Force and the Black Sea and Marmora Division,[2] was a naval formation of the British Mediterranean Fleet from 1918 to 1919.
On 19 December 1918 the Commander-in-Chief, Mediterranean Fleet instructed Rear-Admiral Michael Culme-Seymour, then commanding British Aegean Squadron, that he was to be re-assigned to a new command appointment. On 1 January he transferred his current command to Commodore Maurice Fitzmaurice and assumed authority for the Black Sea, Caspian Sea, Sea of Azov and Sea of Marmora.[1] The squadron was involved in the Allied intervention in the Russian Civil War. In October 1919 Rear-Admiral Seymour was appointed Second-in-Command, Mediterranean Fleet, and the squadron was disbanded. The squadron's flagship was HMS Emperor of India.[3]
A component of the squadron was the British Caspian Flotilla.
