Operation Vigorous
Operation Harpoon or Battle of Pantelleria (Italian: "Battaglia di Mezzo Giugno") was one of two simultaneous Allied convoys sent to supply Malta in the Axis-dominated central Mediterranean Sea in mid-June 1942, during the Second World War. Operation Vigorous was a westward convoy from Alexandria run at the same time Operation Harpoon was an eastbound convoy operation from Gibraltar. Two of the six ships in the Harpoon convoy completed the journey, at the cost of several Allied warships. The Vigorous convoy was driven back by the Italian fleet and attacks by Axis aircraft.
