Repairs were completed before the end of the month, and she escorted a convoy to Greece, during which her Fulmars shot down one shadowing CANT Z.506B floatplane. She sailed from Alexandria on 6 November, escorted by the battleships , , and "Valiant", two light cruisers, and 13 destroyers, to provide air cover for another convoy to Malta. At this time her air group was reinforced by several of "Eagles"s Gloster Sea Gladiators supplementing the fighters of 806 Squadron as well as torpedo bombers from 813 and 824 Squadrons. The former aircraft were carried "...as a permanent deck park..." and they shot down a CANT Z.501 seaplane two days later. Later that day seven Savoia-Marchetti SM.79 medium bombers were intercepted by three Fulmars, which claimed to have shot down one bomber and damaged another. In reality, they heavily damaged three of the Italian aircraft. A Z.501 searching for the fleet was shot down on 10 November by a Fulmar and another on the 11th. A flight of nine SM.79s was intercepted later that day and the Fulmars claimed to have damaged one of the bombers, although it actually failed to return to base. Three additional Fulmars had been flown aboard from "Ark Royal" a few days earlier, when both carriers were near Malta; that brought its strength up to 15 Fulmars, 24 Swordfish, and two to four Sea Gladiators. Three Swordfish crashed shortly after take-off on 10 and 11 November, probably due to fuel contamination, and the maintenance crewmen spent all day laboriously draining all the fuel tanks and refilling them with clean petrol. This left only 21 aircraft available for the attack.
