In the fall of 1942, the destroyer took part in the landings of the invasion of North Africa Operation "Torch." As a member of the Eastern Naval Task Force, she covered landings near Algiers. On 12 November 1942, the destroyer attacked a German U-boat in waters north of Oran, Algeria, and claimed to have sunk the enemy vessel. "Clare" left Gibraltar on 17 November 1942, returned to Britain, and resumed transatlantic convoy duty.
