Eleventh Sloop Flotilla (Royal Navy)
The Eleventh was one of six new flotillas to first appear in the Navy List in July, 1918, joining the long-established First Sloop Flotilla and Tenth Sloop Flotilla. It was based at Gibraltar, and was formed from a number of sloops that had been directly attached to the station for a considerable time already.
