In late May, the German fleet commander, "VAdm" Reinhard Scheer, planned to conducted another fleet operation. The plan called for the battlecruiser squadron to steam north to the Skagerrak, with the intention of luring out a portion of the British fleet so it could be destroyed by Scheer's waiting battleships. The Germans had at their disposal sixteen dreadnought battleships, six pre-dreadnoughts, and five battlecruisers, along with numerous cruisers and torpedo boats. In the early hours of 30 May, the German fleet got underway "Frauenlob" remained with IV Scouting Group for the operation, which was at that time under the command of "Kommodore" (Commodore) Ludwig von Reuter and was tasked with screening the High Seas Fleet. Unknown to the Germans, the Royal Navy's Room 40 had intercepted and decrypted German radio traffic containing plans of the operation. The Admiralty ordered the Grand Fleet, totalling some 28 dreadnoughts and 9 battlecruisers, to sortie the night before to cut off and destroy the High Seas Fleet.
