 The primary goal and strategy of the 2nd Escort Group as 'hunter-killers of U-boats' was reflected in the group practice of playing the song 'A-Hunting We Will Go' upon entering and leaving harbour.This practice was emulated by other Royal Navy ships and was evidence of the change of attitude and strategy of anti-submarine units from defenders to hunter/killers of U-Boats.The group's first patrol in May 1943 was uneventful.
