Thanks for the comments everyone! I have planned what I'll do next and it'll keep me busy for a while. For now it's this class here and there were seven cruisers in it, so it's quite a long way to go still.
With the outbreak of the War,
Hamburg rejoined the active fleet, but retained her role as U-Boat Flotilla flagship. On August 6th, 1914, she and
Stettin escorted U-Boats out into the North Sea to lure out the British Fleet and have them ambushed by said U-Boats. The mission ended without any encounter of British Ships. As part of the IV. Scouting Group,
Hamburg participated in the bombardment of British harbours, once again to lure out parts of the British Fleet and destroy them piece by piece. During one of such encounters,
Hamburg and several other destroyers and cruisers encountered and damaged several British destroyers.
On May 21st, 1915 while travelling on the Weser,
Hamburg rammed torpedo boat S21 and cut it in half.
In 1916
Hambug participated in the Battle of Jutland. As part of the Scouting Forces, she and
V73 escorted the II. Battle Squadron. She did not participate in the early phases of the Battle, but came under fire in the night of May31st, 1916 by British light cruisers. The encounter happened at long range and in poor visibility and
Hamburg fired only one salve, but sustained two hits, killing 14 and wounding 25 more. The cruiser underwent repairs until July 26th, 1916.
By 1917,
Hamburg was no longer fit for frontline service and was used as a barracks ship for the leader of the U-Boats in Wilhelmshaven. She was not handed over to the allies after the end of the war and was decommissioned in 1919.
