In any case, Rommel is vacationing in Italy with his wife Lucie to celebrate his 50th birthday.
Operation Perpetual. British aircraft carriers HMS Ark Royal and HMS Argus depart Gibraltar, escorted by battleship HMS Malaya, cruiser HMS Hermione and 7 destroyers, transporting 37 Hurricane fighters to be flown to Malta.
