"Devonshire" returned home in early 1941 and briefly rejoined the Home Fleet, during which time she escorted several aircraft carriers as they attacked German forces in Norway and Finland and covered the first convoy to the Soviet Union. Shortly afterwards, the ship was sent to the South Atlantic where she sank the Q-ship . "Devonshire" was then assigned to the Eastern Fleet in the Indian Ocean and supported the Allied invasion of Madagascar in mid-1942. She then spent the next year escorting convoys before returning home to begin a lengthy refit. After it was completed in early 1944, the ship escorted various aircraft carriers for the rest of the war as they attacked targets in Norway.
