Naval service

Karlsruhe was earmarked to replace the Dresden on the Caribbean Station and to take part in the opening ceremonies of the Panama Canal; but war broke out and she immediately began commerce raiding, sinking 17 merchant vessels totalling 76,609grt. On 4 November 1914 she sank at position 11°07' N 055°25' W after an accidental internal explosion. The survivors were saved by two German supply ships and managed to reach Germany on board the blockade runner Rio Negro.

Rostock served with the Scouting Group of the High Seas Fleet, and took part in the Battle of Jutland where she received a torpedo hit, and was finally sunk by the German torpedo boats V71 and V73 on 1 June 1916.
