Operation Portcullis (1–5 December 1942) was the voyage of the Allied Convoy MW 14 with supplies to Malta from Port Said in Eygpt during the Second World War. The convoy followed the success of Operation Stoneage (16–20 November) which had raised the Siege of Malta. Four merchant ships were escorted to Malta by seven destroyers of the 12th Destroyer Flotilla, supported by three cruisers of the 15th Cruiser Squadron and three destroyers from Alexandria.
The convoy was met by Force K from Malta with two cruisers and four destroyers. MW 14 was not attacked by Axis forces en route or while unloading which was complete by 9 December. Lack of opposition led to the sailing of pairs of ships to Malta with ordinary western desert convoys as far as Benghazi. The ships rendezvoused with escorts from Malta and Force K guarded against a sortie by Italian ships from Taranto.
Background
Malta
In the autumn of 1942, the British regained control of the central Mediterranean, through the combined effects of the survival of Malta, brought about by the success of Operation Pedestal (3–15 August 1942) and Operation Stoneage (16–20 November), the Second Battle of Alamein (23 October – 11 November) in Egypt and Operation Torch (8–16 November) the Allied invasion of French North Africa. Offensive operations from Malta had been resumed with the supplies delivered by Pedestal and intensified with those of Stoneage. Axis shipping losses contributed to the chronic fuel shortage that constrained Panzerarmee Afrika and limited it to delaying actions back to the Tunisian border. With the revival of Malta as an offensive base after the arrival of the Stoneage convoy, the short journey by Axis ships from Italy to Tunis and Tripoli became much more hazardous. Allied submarines sank 14 Italian ships in October and in November the air anti-shipping offensive had similar success, sinking 21 ships.
The fast Abdiel class minelayer HMS Manxman sailed from Alexandria on 10 November and arrived on 12 November with powdered milk, cereals and meat, leaving for Gibraltar that day to collect mines and lay them off Cape Bon. HMS Welshman detached from a convoy bringing supplies to North Africa for Operation Torch and arrived on 18 November. Force K was re-established at Malta on 27 November with the cruisers HMS Cleopatra, Dido and Euryalus of the 15th Cruiser Squadron and four ships of the 14th Destroyer Flotilla, taken from the Stoneage convoy escorts. Force Q, the 12th Cruiser Squadron with HMS Aurora, Penelope, Dido and Sirius with four destroyers moved to Bône (now Annaba) on 30 November.
North Africa
As the Panzerarmee retreated, the Axis air forces had to leapfrog backwards from airfield to airfield. The Desert Air Force swiftly took over abandoned airfields and the landing grounds at Gazala were open by 17 November; Martuba, near Derna, was operational on 19 November and the Navy began scheduled convoys to Benghazi on 26 November. Ultra intercepts of Axis Enigma machine cyphers revealed that on 24 November, the Panzerarmee had only a few days' fuel left and on 3 December, that Italian troops were withdrawing to Buerat. By the middle of November the Panzerarmee retreat from Alamein had reached El Agheila. The front was 110 mi (180 km) wide and had to be held with a force that was a shadow of the Axis force that had been in Egypt that October. The front settled while the British built up their supplies for an attack and the Axis forces tried to get supplies to the Panzerarmee across the Mediterranean.
Prelude
Axis command
The Axis command structure in the Mediterranean was centralised at the top and fragmented below. Benito Mussolini had monopolised authority over the Italian armed forces since 1933 by taking the offices of Minister of War, Minister of the Navy and Minister of the Air Force. Feldmarschall Albert Kesselring of the Luftwaffe commanded German ground forces in the theatre as Commander-in-Chief South (Oberbefehlshaber Süd, OB Süd) but had no authority over Axis operations in North Africa or the organisation of convoys to Libya. Fliegerkorps II and Fliegerkorps X came under the usual Luftwaffe chain of command. Since November 1941, Kesselring had exercised some influence over the conduct of the German naval operations in the Mediterranean as the nominal head of Naval Command Italy (Marinekommando Italien) but this was subordinate to the Kriegsmarine chain of command. German service rivalries obstructed co-operation and there was little unity of effort between German and the Italian forces in the Mediterranean. Kesselring had the authority only to co-ordinate plans for combined operations by German and Italian forces and some influence on the use of the Regia Aeronautica for the protection of convoys to North Africa. The Italian Navy resisted all German attempts to integrate its operations; ships in different squadrons never trained together and Supermarina (Italian Naval High Command) constantly over-ruled subordinate commanders.

Convoy MW 14 consisted of the Agwimonte (6,679 gross register tons [grt]), Alcoa Prospector (6,797 grt), Suffolk (13,890 grt) and Glenartney (9,795 grt) which had a naval crew. A continuous escort was provided by seven Hunt-class destroyers of the 12th Destroyer Flotilla, comprising HMS Aldenham, Belvoir, Croome, Exmoor, Hursley, Tetcott and the Greek Pindos after the tanker Yoruba Linda joined from Benghazi with its two escorts. The next day, the 6-inch cruiser [6 in (150 mm)] HMS Orion with the destroyers Pakenham, Petard and Vasilissa Olga were to join from Alexandria. When south-west of Crete, the convoy was to be met by the 5.25-inch cruisers [5.25 in (133 mm)] Dido and Euryalus, with the fleet destroyers HMS Jervis, Javelin, Kelvin, Nubian of Force K (Rear-Admiral Arthur Power) from Malta.
Convoy MW 14
During the evening of 1 December, convoy MW 14 departed Port Said and on 2 December, rendezvoused with the tanker Yorba Linda and two Hunt-class destroyers. Next day, the cruiser Orion and three destroyers arrived from Alexandria and on 4 December, when south-west of Crete, the convoy was joined by Force K, comprising two cruisers and four destroyers from Malta. The convoy steamed for Malta at 16 kn (18 mph; 30 km/h), receiving only a few ineffectual attacks from Axis torpedo-bombers. The convoy reached Grand Harbour early on 5 December and received the customary welcome from the populace and garrison. As the swift unloading of the ships began, congestion in the harbour was relieved by Operation MH 2, the dispatch of Convoy ME 11 on 7 December, containing Yoruba Linda from MW 14 and eight ships from Pedestal and Stoneage. By 9 December the ships were unloaded.
