"Garland", "Grafton", "Gallant", "Hasty" and "Hereward" were either under repair or refitting during the early stages of the Norwegian Campaign and did not participate in the Battles of Narvik in April. The remaining ships were assigned to the Home Fleet by this time. "Glowworm" was separated from the battlecruiser in a heavy storm on 8 April and encountered the German heavy cruiser and several destroyers. The British destroyer could not disengage and was sunk after ramming "Admiral Hipper". "Hardy", "Havock", "Hostile", "Hotspur" and "Hunter" participated in the First Battle of Narvik on 10 April. They sank two German destroyers in exchange for the loss of "Hardy" and "Hunter", while "Hotspur" was badly damaged. That same day, "Hero" sank the off the Norwegian coast and was the only G- or H-class destroyer to participate in the Second Battle of Narvik three days later. "Griffin" and "Hasty" helped to cover the evacuation of Allied troops from Namsos and Åndalsnes at the end of the month. "Havelock" escorted the transports conducting the evacuation of Narvik in June. "Garland" was loaned to the Polish Navy in May after her repairs were finished and she remained in the Mediterranean, escorting convoys between Malta and Alexandria, Egypt, until she was transferred to the Western Approaches Command in September.
