Torpedo Sub-Depôt Ship "Sokoto" lying in the Inner Hope.
The Brough of Birsay, off which H.M.S. "Hampshire" was lost on 6th June, 1916.
Meantime the duties of "Imperieuse" were still further relieved by the arrival of other vessels. R.F.A. "Ruthenia," previously a dummy battleship, became the storeship and headquarters of the Victualling and Naval Store Officers, and the Fleet Coaling Officer took up his quarters in R.F.A. "Perthshire" in the secluded waters of Pegal Bay; whilst the "Sokoto" (a depôt ship for the storing and repair of torpedoes) and M.F.A. "Zaria" (repair ship for small craft, such as drifters, trawlers, etc.) were already at Long Hope.
