Operation Vigorous
Operation Vigorous (12-16 June 1942; known in Italy as the "Battle of Mid June") was instead his most important success; despite the losses caused by air and submarine attacks (the battleship "Littorio" was torpedoed, and the heavy cruiser "Trento" was sunk), he kept advancing towards the British convoy sailing from Alexandria to Malta, eventually leading to it aborting its mission and turning back to port.
