 Throughout 1917 the Admiralty was becoming more concerned about German efforts to sweep paths through the British-laid minefields intended to restrict the actions of the High Seas Fleet and German submarines. A preliminary raid on German minesweeping forces on 31 October by light forces destroyed ten small ships. Based on intelligence reports, the Admiralty allocated the 1st Cruiser Squadron on 17 November 1917, with cover provided by the reinforced 1st Battlecruiser Squadron and distant cover by the battleships of the 1st Battle Squadron, to destroy the minesweepers and their light cruiser escorts.
