He is most famous for commanding the German battlecruisers of the I Scouting Group during World War I, particularly at the Battle of Jutland on 31 May – 1 June 1916. During the war, Hipper led the German battlecruisers on several raids of the English coast, for which he was vilified in the English press as a "baby killer". His squadron clashed with the British battlecruiser squadron at the Battle of Dogger Bank in January 1915, where the armored cruiser Blücher was lost.
