The ship covered an amphibious landing during the Syria–Lebanon Campaign of June 1941 and began escorting supply convoys in June to Tobruk, Libya shortly afterwards. She was damaged by German dive bombers while rescuing survivors from the minelayer in October 1941 and resumed escorting convoys to Malta. "Hero" participated in the Second Battle of Sirte in March 1942 and in Operation Vigorous in June. She sank two German submarines whilst stationed in the Mediterranean in 1942, and was transferred back home late in the year to begin converting to an escort destroyer. The ship was transferred to the Royal Canadian Navy (RCN) in 1943 and renamed HMCS "Chaudière". She became part of the Mid-Ocean Escort Force in early 1944 until her transfer back to British coastal waters in May to protect the build-up for Operation Overlord. Together with other ships, she sank three more German submarines during the year. "Chaudière" was refitting when the war ended in May 1945 and was in poor shape. The ship was paid off in August and later sold for scrap. The process of breaking her up, however, was not completed until 1950.
