sides were still maneuvering, a group of British torpedo bombers from Crete arrived and unsuccessfully attacked Trento and the rest of her division shortly after 12:00. Further attacks from the aircraft carrier convinced Iachino to break off the action and withdraw at 12:20. Later in the day, Vittorio Veneto and Pola were torpedoed by British aircraft, the latter left immobilized. Trento, Trieste, and Bolzano were also attacked by aircraft, but they escaped without damage. Trento reached Taranto in company with the damaged Vittorio Veneto at 15:30 the following day. In the meantime, Pola and two other Zara-class cruisers were destroyed in the night action with British battleships late on the 28th. Convoy operations and loss Trento moved to La Spezia on 6 May for an extensive overhaul that lasted until 5 August, at which point she returned to Messina. She took part in the Duisburg convoy on 8–9 November along with Trieste, the two ships serving as the convoy's covering force. The convoy was attacked by British warships in the early hours of 9 November, though the covering force failed to intervene and the convoy was destroyed. Another convoy followed on 21 November, and during the crossing Trento helped to defend against a British air attack. Less than a month later, on 16 December, Trento joined most of the other heavy units of the fleet to escort two large convoys to Benghazi and Tripoli. The following day, the fleet encountered British forces covering a merchant ship steaming to Malta, leading to the inconclusive First Battle of Sirte. On 22 March 1942, Trento joined the battleship , the cruisers and , and several destroyers in an attempt to intercept a British convoy. In the Second Battle of Sirte, the four ships attacked Convoy MW10, but the British escorts—four light cruisers and eighteen destroyers—prevented the Italians from attacking the merchant ships. According to some sources, Trento scored a hit on the destroyer in this action, inflicting heavy damage. Two Italian destroyers, and , foundered in heavy weather after the battle; Trento attempted to come to their aid, but they sank before she could reach them. On 14 June, Trento left Taranto with Littorio, Vittorio Veneto, Gorizia, and the light cruisers and to attack the British convoy from Alexandria steaming to Malta in Operation Harpoon. The following morning, while steaming in the Ionian Sea, a British Bristol Beaufort torpedo-bomber scored a hit on
