Passage: Ostfriesland was present during the fleet operation that resulted in the battle of Jutland, which took place on 31 May and 1 June 1916. The German fleet again sought to draw out and isolate a portion of the Grand Fleet and destroy it before the main British fleet could retaliate. During the operation, Ostfriesland was the lead ship in I Squadron's I Division and the ninth ship in the line, directly astern of the fleet flagship Friedrich der Grosse and ahead of her sister Thüringen. I Squadron was the center of the German line, behind the eight König- and Kaiser-class battleships of III Squadron. The six elderly pre-dreadnoughts of III and IV Divisions—II Battle Squadron—formed the rear of the formation. Ostfriesland flew the flag of Vizeadmiral (Vice Admiral) Erhardt Schmidt, the squadron commander during the battle and Scheer's deputy commander.Shortly before 16:00, the battlecruisers of I Scouting Group encountered the British 1st Battlecruiser Squadron under the command of David Beatty. The opposing ships began an artillery duel that saw the destruction of Indefatigable, shortly after 17:00, and Queen Mary, less than half an hour later. By this time, the German battlecruisers were steaming south to draw the British ships toward the main body of the High Seas Fleet. At 17:30, the crew of the leading German battleship, König, spotted both I Scouting Group and the 1st Battlecruiser Squadron approaching. The German battlecruisers were steaming to starboard, while the British ships steamed to port. At 17:45, Scheer ordered a two-point turn to port to bring his ships closer to the British battlecruisers and, a minute later, the order to open fire was given.While the leading battleships engaged the British battlecruiser squadron, Ostfriesland and ten other battleships fired on the British 2nd Light Cruiser Squadron. Ostfriesland, Kaiser, and Nassau engaged the cruiser Southampton, though only Nassau scored a hit. After about 15 minutes, Ostfriesland shifted fire to Birmingham and Nottingham, though again failed...
