Cardiff was briefly deployed to the Baltic in late 1918 supporting anti-Bolshevik forces during the British campaign in the Baltic during the Russian Civil War.
The C class was a group of twenty-eight light cruisers of the Royal Navy, and were built in seven groups known as the Caroline class, the Calliope class, the Cambrian class, the Centaur class, the Caledon class, the Ceres class and the Carlisle class. They were built for the rough conditions of the North Sea, and proved to be rugged and capable vessels, despite being somewhat small and cramped.
HMS Defence was a Minotaur-class armoured cruiser built for the Royal Navy in the first decade of the 20th century, the last armoured cruiser built for the Royal Navy.

The Boadicea-class cruiser was a pair of scout cruisers built for the Royal Navy in the first decade of the 20th century. They were the first class of this type to be fitted with steam turbine machinery. Upon completion in 1909–10, the sister ships served as flotilla leaders for destroyer flotillas of the First Fleet until 1913 when they were assigned to battleship squadrons. When the First World War began in August 1914, they remained with their squadrons as the First Fleet was incorporated into the Grand Fleet, although they changed squadrons over the course of the war. Both ships were present during the Battle of Jutland in mid-1916, but neither fired a shot.
