The II Battle Squadron was divided into the III Division and the IV Division; the divisions initially were composed of eight of the ten and s. At the time, was the flagship of the High Seas Fleet and was also assigned to the II Battle Squadron, though only for tactical purposes—the ship was not otherwise subordinate to the squadron commander. The II Battle Squadron operated from one of the two primary bases of the German fleet. The first, in the North Sea, was Wilhelmshaven on the western side of the Jade Bight. The island of Heligoland provided a fortified forward position in the German Bight. The second major naval installation was at Kiel, and it was the most important base in the Baltic. Pillau and Danzig housed forward bases further east in the Baltic. The Kaiser Wilhelm Canal through Schleswig-Holstein connected the Baltic and North Seas and allowed the German Navy to quickly shift naval forces between the two seas.
As part of his program of naval expansion to rival the British Royal Navy, Admiral Alfred von Tirpitz projected the need for a second squadron of eight battleships in his 1898 Naval Law. By 1907, enough new battleships had been completed to stand the new squadron up at full strength. The ships of the II Battle Squadron took part in all of the major fleet actions in the first three years of the war. These included the support missions for the battlecruisers of the I Scouting Group as they bombarded the British coast in attempts to lure out part of the British Grand Fleet, such as the raids on Scarborough, Hartlepool and Whitby in December 1914 and on Yarmouth and Lowestoft in April 1916. At the Battle of Jutland in May 1916, the ships formed the rear of the German line, though they saw relatively little combat during the daylight action apart from a brief skirmish with the British battlecruiser squadron. The squadron consisted of only six ships at the time, as had been transferred temporarily to the Baltic for guard duty and was in such poor condition that Scheer removed the ship from the squadron. In the night fighting against the British destroyer flotillas, was torpedoed and sunk, killing her entire crew. Her loss highlighted the vulnerability of the other pre-dreadnoughts to underwater attack, and the II Battle Squadron thereafter remained in port when the High Seas Fleet sortied. On 15 August 1917, the II Battle Squadron was disbanded; the former members of the squadron were thereafter decommissioned and used in subsidiary roles or employed as guard ships.
