During ww1 the ship had a very active career first participating in the battle of Heligoland Blight and bombarding numerous British coastal towns before the battle of Doggerland Bank,during which the German battlecruisers enguaged the British Battlecruisers in a retreating enguagement, eventually losing the Armoured Cruiser Blucher and also recieving a near fatal blow from HMS Tiger striking forecastle barbette, but failing to penetrate and causing a flash fire and detonating the propellent and causing a significant fire to spread between both turrets.
