|Part of||Orkney and Shetlands Command|
A deep sea channel off the west coast of the Shetland Mainland, Swarbacks Minn lies between the islands of Muckle Roe to the north and Papa Little and Vementry to the south. Swarbacks Minn was home to substantial naval operations during the First World War, and was the base for the 10th Cruiser Squadron. This was a squadron of fast armed liners, cruisers and destroyers who patrolled the seas from Ireland to North of Iceland and intercepted and dealt with 15,000 vessels. Duties were to stop goods from reaching Germany, destroy warships and prevent the enemy landing in Shetland. HMS Gibraltar was launched from Napier's Yard on the River Clyde in 1892 and saw service with the 10th Cruiser Squadron at the outset of World War I, before becoming their depot ship based in Swarbacks Minn.
