HMS Boadicea was the lead ship of her class of scout cruisers built for the Royal Navy in the first decade of the 20th century.

[1] Her main armament consisted of six breech-loading (BL) four-inch (102 mm) Mk VII guns.

During the war, four additional four-inch guns were added amidships to increase her firepower.

Boadicea was transferred to the 2nd Battle Squadron on 5 July and Fox was relieved by Captain Louis Woollcombe.

[5] On 31 July 1914, she took Vice-Admiral John Jellicoe from Wick to Scapa Flow to assume command of the Grand Fleet.

[6] She was assigned to the Second Battle Squadron of the Grand Fleet in Scapa Flow at the start of the war.

[7] She was at the Battle of Jutland on 31 May – 1 June 1916, but was assigned to a position at the rear of the squadron and did not fire her guns.

[14] She was paid off on 18 February 1920 at Chatham Dockyard[15] and was used for harbour service at Dartmouth[1] until she was sold for scrap on 13 July 1926 to be broken up at Alloa, Rosyth.
