Service history
Isis deployed to the Mediterranean in 1898 for service in the Mediterranean Fleet. She participated between September and December 1898 in the operations at Crete of the International Squadron, a multinational force made up initially of ships of the Austro-Hungarian Navy, French Navy, Imperial German Navy, Italian Royal Navy, Imperial Russian Navy, and Royal Navy that intervened between February 1897 and December 1898 in the 1897-1898 Greek Christian uprising against the Ottoman Empire′s rule on the island. By the time Isis joined the squadron, Austria-Hungary and the German Empire had withdrawn from the squadron, but the other four countries remained active in it. In the wake of a violent riot by Cretan Turks against British soldiers, sailors, and Christian civilians in Candia on 6 September 1898, Isis anchored in the harbor and men convicted of murdering British subjects during the riot were held aboard her while awaiting trial and execution. They were hanged in Candia during October and November 1898. Isis was still in service with the Mediterranean Fleet when Captain George Morris Henderson took command in early 1900. Captain Charles Windham was appointed in command on 28 December 1900, as she served on the China Station, and remained with the ship until January 1902. In late October 1901 she left Hong Kong homebound, arriving at Spithead in December. She paid off at Chatham on 18 January 1902 and was placed in the Fleet Reserve as emergency ship. In May 1902, she was briefly tender to, cadet training ship at Dartmouth. Following a refit with new steam and gunnery trials, Captain Godfrey H. B. Mundy was appointed in command on 19 September 1902, when she was recommissioned as tender to the Britannia. In early October she left Plymouth for Gibraltar with cadets from the Britannia, following which she went to Las Palmas, cruising in the vicinity of the Canary Islands until she returned to Plymouth via Madeira in late November. On 22 April 1914, she collided with the British cargo ship in the English Channel, sinking Carbineer south-southeast of the Owers Lightship; Isis rescued Carbineer′s crew. In August 1914 with the outbreak of war, Isis was brought out of the reserve and attached to the 11th Cruiser Squadron based on Queenstown, Ireland. She was later transferred to the North American and West Indies Station, and was scrapped in 1920.
