In early 1942 Diomede joined the 9th Cruiser Squadron as part of the South Atlantic and West African Squadron. After more than a decade of steaming it was decided to retire her from front-line service and from 22 July 1942 to 24 September 1943 at Rosyth Dockyard she converted into a training ship. With the end of the war she was reduced to reserve. On 5 April 1946 she was sold for scrap to Arnott Young of Dalmuir and arrived there for breaking up on 5 May.
