HMS Euryalus was a Cressy-class armoured cruiser built for the Royal Navy, with a displacement of approximately 12,000 long tons. Laid down on 18 July 1899 by Vickers, Sons & Maxim at Barrow-in-Furness, she was launched on 20 May 1901. Her construction was marred by significant setbacks, including a fire that damaged her teak sheathing during launch and a collision during sea trials that resulted in the sinking of the fleet tug HMS Traveller. These incidents delayed her completion until 5 January 1904. She measured 472 feet in length overall, with a beam of 69 feet 9 inches, and a deep draught of 26 feet 9 inches. Powered by two 4-cylinder triple-expansion steam engines generating 21,000 indicated horsepower, she could reach a maximum speed of 21 knots, fueled by 30 Belleville boilers. Her armament comprised two 9.2-inch breech-loading guns in single turrets fore and aft, twelve 6-inch guns in casemates amidships, and several smaller guns for defense against torpedo boats, along with two submerged 18-inch torpedo tubes. Her armor featured a waterline belt up to 6 inches thick, with 6-inch turrets, 5-inch casemate armor, and a 12-inch thick conning tower. Euryalus's service history included early roles as flagship of the Australia Station and later training duties in the North America and West Indies Station. At the outbreak of World War I, she was assigned to the 7th Cruiser Squadron, serving as flagship for the Southern Force tasked with defending the eastern English Channel. She participated in the Battle of Heligoland Bight but saw no combat. Subsequently, she undertook convoy escort duties in the Bay of Biscay and supported British operations during the Gallipoli Campaign, notably providing naval gunfire during the landings at Cape Helles and subsequent battles. Later, she served as flagship of the East Indies Station from January 1916 until July 1917, before beginning a conversion to a minelayer in Hong Kong, which was incomplete at war’s end. After returning to Britain in 1919, she was sold for scrap in 1920 and dismantled starting in 1922. Euryalus's career highlights her as a versatile cruiser that served across various theaters, reflecting the strategic naval priorities of the Royal Navy in the early 20th century.
