A second operation followed on 15–16 December 1914; it targeted the towns of Scarborough, Hartlepool, and Whitby. By this time Hipper's squadron had been augmented by the new battlecruiser Derfflinger. Twelve hours after Hipper left the Jade, the High Seas Fleet, consisting of 14 dreadnoughts and 8 pre-dreadnoughts and a screening force of 2 armored cruisers, 7 light cruisers, and 54 torpedo boats, departed to provide distant cover for the bombardment force.[22] The Royal Navy had the capability to intercept and decode the German naval code, as a result of the capture of the light cruiser Magdeburg at the outbreak of the war.
