The Malta convoys were Allied supply convoys of the Second World War. The convoys took place during the Siege of Malta in the Mediterranean Theatre. The civilian population and the garrison required imports of food, medical supplies, fuel and equipment; the military forces on the island needed reinforcements, ammunition and spare parts. British convoys were escorted to Malta by ships of the Mediterranean Fleet and aircraft of the Fleet Air Arm and Royal Air Force, during the Battle of the Mediterranean (1940–1943). British and Allied ships were attacked by the Italian Regia Aeronautica (Royal Air Force) and Regia Marina (Royal Navy) in 1940 and starting in 1941, by the Luftwaffe (German Air Force) and Kriegsmarine (German Navy).
Malta was a base from which British sea and air forces could attack Italian ships carrying supplies from Italy to Italian Libya for Italian civilian colonists and the Axis armies in North Africa, which fought the Western Desert Campaign (1940–1943) against the British Eighth Army. The war in the desert was fought for control of Libya and Egypt, the Suez Canal and British controlled oilfields in the Middle East. The strategic value of Malta was so great that the British risked many merchant vessels and warships to supply the island and the Axis made determined efforts to starve out the population. The destruction of the Italian 10th Army, in Egypt and Libya during Operation Compass (9 December 1940 – 9 February 1941) and defeat in the Italo-Greek War (28 October 1940 – 23 April 1941) led to German intervention in the Mediterranean. German bombers and submarines joined the effort to neutralise Malta and preparations were made to invade the island.
The British assembled large flotillas of warships to escort convoys, sent fast warships to make solo runs to the island and organised Magic Carpet supply runs by submarine. Hawker Hurricane and then Supermarine Spitfire fighters were flown to Malta from aircraft carriers on Club Runs from Gibraltar towards Malta. In mid-1942, Axis air attacks on the island and on supply convoys neutralised Malta as an offensive base and an Axis invasion, Unternehmen Herkules (Operation Hercules), was set for mid-July 1942. After the Axis victory in the Battle of Gazala (26 May – 21 June 1942) in Libya, the capture of Tobruk and then the Axis pursuit of the Eighth Army into Egypt, Herkules was postponed and then cancelled. The siege of Malta eased late in 1942, after the Second Battle of El Alamein (23 October–11 November) and Operation Torch (8–16 November), when the Allies captured territory and landing grounds in Libya and Algeria, bringing more of the seas around Malta into range of land-based Allied aircraft. Regular through convoys from Gibraltar to Alexandria and back were resumed and ships were detached from the convoys and escorted to and from Malta.
Malta, a Mediterranean island of 122 square miles (320 km2), had been a British colony since 1814. By the 1940s, the island had a population of 275,000 but local farmers could feed only one-third of the population, the deficit being made up by imports. Malta was a staging post on the British Suez Canal sea route to India, East Africa, the oilfields of Iraq and Iran, India and the Far East. The island was also close to the Sicilian Channel between Sicily and Tunis and was a military base from which Italian ships sailing to Libya could be attacked.
When Italy declared war on Britain and France on 10 June 1940, the Taranto Naval Squadron did not sail to occupy Malta as suggested by Admiral Carlo Bergamini. With Italian bases in Sicily, British control of Malta was made more difficult from its bases in Gibraltar to the west and Cyprus, Egypt and Palestine to the east, which were much further away. Two weeks after the Italian declaration of war, the Second Armistice at Compiègne (between France and Germany) ended British access to Mediterranean Sea bases in France and passage to Mediterranean colonies. The British attack on Mers-el-Kébir (3 July 1940) against French naval ships, created a Vichy French antagonism towards Britain. Axis support for General Francisco Franco in the Spanish Civil War also caused British to be apprehensive about the security of the British base at Gibraltar.
Italy, Sicily, Sardinia and Libya dominated the central Mediterranean and an Italian conquest of Egypt would link Abyssinia, Italian Somaliland and Eritrea. The Italian invasion of Egypt in September 1940, was followed by Operation Compass, a British counter-offensive in December, which led to the conquest of Cyrenaica in January 1941. Hitler transferred the Luftwaffe's Fliegerkorps X to Sicily (Unternehmen Mittelmeer or Operation Mediterranean) to protect the Axis supply routes past Malta, and sent the Afrika Korps to Libya (Unternehmen Sonnenblume or Operation Sunflower) which, with Italian reinforcements, recaptured Cyrenaica. Fliegerkorps X was transferred to Greece in April 1941 and the 23rd U-boat Flotilla was based at Salamis, near Athens, in September. Resources available to sustain Malta were reduced when Japan declared war in December 1941, and conducted the Indian Ocean raid in April 1942. Malta was neutralised as an offensive base against Italian convoys by the attacks of the Regia Aeronautica and the Luftwaffe in early 1942. Several warships were sunk in Valletta harbour and others were withdrawn to Gibraltar and Egypt. Food and medicines for the Maltese population and the British garrison dwindled along with fuel, ammunition and spare parts with the success of Axis attacks on Malta convoys. The Italian Operation C3 and the German-Italian Unternehmen Herkules (Operation Hercules) invasion plans against Malta were prepared but then cancelled on 16 June 1942.
In the Battle of Calabria (Battaglia di Punta Stilo), Regia Marina escorts (two battleships, 14 cruisers and 32 destroyers) of an Italian convoy engaged the battleships HMS Warspite, Malaya and Royal Sovereign and the aircraft carrier HMS Eagle. The British cruisers and destroyers covered two convoys heading from Malta to Alexandria. The first, Malta Fast 1 (MF 1)/Malta East 1 (ME 1), was composed of the El Nil, Knight of Malta and Rodi; the second, Malta Slow 1 (MS 1)/ME 1 was composed of the Kirkland, Masirah, Novasli, Tweed and Zeeland.
Using an aircraft carrier to ferry land based aircraft to Malta had been discussed by the Admiralty in July and once Italy had declared war, the reinforcement of Malta could be delayed no longer. The training aircraft carrier HMS Argus was used to despatch twelve Hurricanes to Malta from a position to the south-west of Sardinia. Hurry was the first Club Run to reinforce the air defence of the island, despite the British Chiefs of Staff decision two months earlier that nothing could be done to reinforce Malta. Club Runs continued until it was possible to fly the aircraft direct from Gibraltar.
The Mediterranean Fleet escorted fast convoy MF 2 of three transports (carrying 40,000 short tons (36,000 t) of supplies, including reinforcements and ammunition for the island's anti-aircraft defences) from Alexandria and collected another convoy from Gibraltar. En route, Italian airbases were raided; the Regia Marina had superior forces at sea but missed the opportunity to exploit their advantage.
Operation MB 6
Four ships of convoy MF 3 reached Malta safely from Alexandria and three ships returned to Alexandria as convoy MF 4. The convoys were part of Operation MB 6 and the escort included four battleships and two aircraft carriers. An Italian attempt against the returning escort by destroyers and torpedo boats ended in the Battle of Cape Passero, a British success.
The five ship convoy MW 3 from Alexandria and four ship return convoy ME 3 arrived safely, coinciding with a troop convoy from Gibraltar and the air attack on the Italian battle fleet at the Battle of Taranto.
In Operation White, twelve Hurricanes were flown off Argus to reinforce Malta but the threat of the Italian fleet lurking south of Sardinia prompted a premature fly-off from Argus and its return to Gibraltar. Eight Hurricanes ran out of fuel and ditched at sea, with seven pilots lost. An enquiry found that the Hurricane pilots had been insufficiently trained about the range and endurance of their aircraft.
Operation Collar was intended to combine the passage of a battleship, heavy cruiser and light cruiser with mechanical defects from Alexandria to Gibraltar, with a four-ship convoy MW 4 to Malta and the sailing of ME 4 from Malta comprising Cornwall and the four empty ships from convoy MW 3, escorted by a cruiser and three destroyers. Attacks on Italian airfields in the Aegean and North Africa were to be made at the same time. Three ships at Gibraltar, two bound for Malta and one for Alexandria were to be escorted by the cruisers HMS Manchester and HMS Southampton. Operation MB 9 from Alexandria began on 23 November, when convoy MW 4 with four ships sailed with eight destroyer escorts, covered by Force E of three cruisers. Force D comprising a battleship and two cruisers sailed on 24 November and next day, two more battleships, an aircraft carrier, two cruisers and four destroyers of Force C departed Alexandria. MW 4 reached Malta without incident; ME 4 had sailed on 26 November, two destroyers returned to Malta; the cruiser and one destroyer saw the freighters into Alexandria and Port Said on 30 November.
Force F from Gibraltar was to pass 1,400 soldiers and RAF personnel from Gibraltar to Alexandria in the two cruisers, slip two supply ships into Malta and one to Crete. The other warships destined for the reinforcement of the fleet at Alexandria were to be sent on, the cruisers being accompanied by two destroyers and four corvettes. Force B provided the covering force with the battlecruiser Renown, the aircraft carrier Ark Royal, the cruisers Sheffield and Despatch and nine destroyers. The destroyers and corvettes left Alexandria on the night of 23/24 November to rendezvous with the merchant ships and their destroyer escorts from Britain. The cruisers embarked the troops and RAF personnel, leaving Gibraltar on 25 November. The British were unaware that Italian reconnaissance aircraft had spotted the sailings from both ends of the Mediterranean and set up submarine ambushes. Two Italian battleships, three cruisers and two destroyer flotillas had left harbour, more cruisers, destroyers and torpedo boats following. Force D was attacked on the night of 26/27 November but the attack was so ineffectual that the British did not notice. On 27 November, aircraft from Force F spotted the Italian battle fleet, the force headed for Force D and prepared to defend the merchant ships, in what became a confused and inconclusive engagement. Two Italian submarines attacked three cruisers in the Sicilian Narrows as they waited for the eastbound convoy on the night of 27/28 November to no effect and the two ships for Malta arrived on 29 November, as Force H returned to Gibraltar and the through convoy and naval ships reached Alexandria.
Convoy MW 5A with Lanarkshire and Waiwera carrying supplies and munitions and convoy MW 5B of Volo, Rodi and Devis, the tanker Pontfield, Hoegh Hood and Ulster Prince from Alexandria with a covering force of a battleship, two cruisers, destroyers and corvettes reached Malta on 20 December and convoy ME 5 with the empty Breconshire, Memnon, Clan Macaulay and Clan Ferguson were collected by the covering force and returned to Alexandria. Convoy MG 1 with Clan Forbes and Clan Fraser reached Gibraltar from Malta escorted by the battleship and four destroyers.
Operation Excess delivered one ship from Gibraltar to Malta and three to Piraeus. The operation was coordinated with Operation MC 4, consisting of convoy MW 5 1⁄2 of Breconshire and Clan Macaulay from Alexandria to Malta, and convoys ME 6, a return journey of ME 5 1⁄2 with Lanarkshire and Waiwera and ME 6, with Volo, Rodi, Pontfield, Devis, Hoegh Hood, Trocas and RFA Plumleaf. The convoys arrived safely with 10,000 short tons (9,100 t) of supplies. The Royal Navy lost the cruiser HMS Southampton; the cruiser HMS Gloucester and aircraft carrier HMS Illustrious were badly damaged and a destroyer was damaged beyond repair. This was the first action to involve the Luftwaffe. The Italian torpedo boat Vega was sunk in the course of the operations.
Operation MC 8
Operation MC 8 from 19–21 February, ran troops, vehicles and stores to Malta in the cruisers Orion, Ajax and Gloucester and the Tribal-class destroyers Nubian and Mohawk, covered by Barham, Valiant, Eagle, Coventry, Decoy, Hotspur, Havock, Hereward, Hero, Hasty, Ilex, Jervis, Janus and Jaguar. The return journey to Alexandria with the unloaded Breconshire and Clan Macaulay by 23 February was uneventful.
Operation MC 9
Operation MC 9 covered convoy MW 6 consisting of Perthshire, Clan Ferguson, City of Manchester and City of Lincoln, which sailed from Alexandria on 19 March, the escorts sailing a day later, covered by the Mediterranean Fleet until the night of 22/23 March. The ships sailed by indirect routes and bad weather enabled the convoy to evade Axis air reconnaissance. The ships arrived at Malta but two ships were bombed while berthed in harbour. No merchant ships were waiting to return from Malta and a cruiser and a destroyer were damaged during the passage but the escorts reached Egypt on 26 March.
Operation Winch and convoy ME 7
Hurricanes delivered to Gibraltar on Argus were put on board Ark Royal, which sailed on 2 April, escorted by the battleship Renown a cruiser and five destroyers. The Hurricanes were flown off on 3 April and all arrived, Force H returning safely to Gibraltar on 4 April. Stores and ammunition were run to Malta in Operations MC 8 and MC 9. On 18 April, the Mediterranean Fleet sailed from Alexandria to Suda Bay in Crete with Breconshire carrying oil and aviation fuel for Malta. Late on 19 April, the Malta Strike Force destroyers sailed with convoy ME 7 of four empty cargo ships. Breconshire made a run into Malta and the destroyers returned after joining in a shore bombardment by the main fleet. The cruiser Gloucester, which had a long range, joining the force.
In Operation Dunlop, HMS Ark Royal sailed from Gibraltar on 24 April and flew off 24 Hurricanes at dawn on 27 April. Bristol Blenheims and Beaufighters were also flown direct from Gibraltar. Three battleships and an aircraft carrier covered the fast transport Breconshire (now commissioned into the RN) from Alexandria to Malta. The operation was coordinated with the four-ship convoy ME 7 from Malta to Alexandria. On 16 April, the value of Malta for offensive operations was shown when four destroyers of the 14th Flotilla (the Malta Striking Force), recently based in the island, sank a five-ship Axis convoy of 14,000 long tons (14,000 t) and its escorts in the Battle of the Tarigo Convoy.
During Operation Temple, the freighter Parracombe sailed for Malta from Gibraltar on the night of 28/29 April, disguised as a Spanish merchantman and later as the Vichy steamer Oued-Kroum. The vessel was lost on 2 May after striking a mine, which blew off the forepart of the ship. The ship sank with 21 Hurricanes, equipment, ammunition and military freight; another ship reached Alexandria from Malta as convoy MD 3.
Operations Tiger and Splice
In Operation Tiger, convoy WS 8 sailed from Gibraltar to Alexandria, combined with a supply run to Malta by six destroyers of Force H. Five 15 kn (17 mph; 28 km/h) merchant ships passed Gibraltar on 6 May accompanied by Force H, along with a battleship and two cruisers en route to Alexandria. The destroyers from Force H participated in the convoy operation as far as Malta. The fleet at Alexandria sailed westwards, bombarded Benghazi on the night of 7/8 May and rendezvoused with the convoy 50 nmi (58 mi; 93 km) south of Malta late on 9 May. In Operation Splice, a Club Run from 19 to 22 May, 48 more Hurricanes were flown off Ark Royal and Furious on 21 May and all reached Malta. Slow convoy MW 7B with two tankers sailed from Egypt for Malta with 24,000 long tons (24,000 t) of fuel oil, followed by fast convoy MW 7A with six freighters escorted by five cruisers, three destroyers and two corvettes. Abdiel and Breconshire sailed with the main fleet and all the ships reached Grand Harbour on 9 May preceded by a minesweeper, which detonated about twelve mines. In May, the Luftwaffe transferred Fliegerkorps X from Sicily to the Balkans, relieving pressure on Malta and the British convoys until December.
In June, the new carrier HMS Victorious replaced Furious on Club Runs and Furious began to ferry fighters from Britain to Gibraltar. On 13 June, Ark Royal and Victorious began Operation Tracer when they sailed from Gibraltar into the western Mediterranean escorted by Force H and on 14 June flew off 47 Hurricanes to Malta guided by four Hudsons from Gibraltar, 43 of the Hurricanes reached Malta.
Operations Railway I and II
On 26 June Ark Royal and Furious sailed again with 22 Hurricanes, guided to Malta by Blenheims from Gibraltar; all arrived at Malta in bad weather and a Hurricane crashed on landing. Force H reached port on 28 June, Furious having steamed back to Britain to collect more Hurricanes, some of which were put aboard Ark Royal. Crated aircraft were assembled on Furious as it joined Force H for Operation Railway II and on 30 June, 26 Hurricanes took off from Ark Royal. The second fighter to take off from Furious skidded a fuel tank fell off and caught fire as the Hurricane went overboard, killing nine men and injuring four more before the fire was extinguished; it took until the early afternoon for the 35 remaining Hurricanes to land at Malta, having been guided by six Blenheims. During the month 142 aircraft reached Malta, some of which continued on to Egypt.
In Operation Substance, convoy GM 1 of six ships containing 5,000 soldiers, ran from Gibraltar to Malta, escorted by six destroyers, covered by the battleship Nelson and three cruisers from the Home Fleet and Force H comprising Ark Royal, Renown and several cruisers and destroyers. The convoy reached Gibraltar from Britain on 19 July and sailed for Malta on 21 July, except for the troopship RMS Leinster which ran aground and had to return to Gibraltar with its 1,000 troops and the RAF ground crews destined for Malta. The Eastern Fleet sortied from Alexandria as a diversion and eight submarines watched Italian ports and patrolled the routes that an Italian sortie was expected to use. Force H was to return to Gibraltar at the Sicilian Narrows and the close escort of three cruisers, Manxman and ten destroyers would continue to Malta. During the convoy operation, Breconshire and six other empty ships at Malta were independently to return to Gibraltar in Operation MG 1. On 23 July, south of Sardinia, Italian air attacks began, a cruiser was hit and had to return to Gibraltar; a destroyer was so badly damaged that it was sunk by the British but the air cover from Ark Royal enabled the convoy to reach the Skerki Channel by late afternoon. The covering force turned for Gibraltar and the rest of the ships sailed on as more Regia Aeronautica aircraft attacked, forcing another damaged destroyer to drop out and return to Gibraltar. By turning north the convoy evaded Italian aircraft sent to attack during the night but on the night of 23/24 July, the 12,000 GRT steamer Sydney Star was torpedoed by an Italian MAS boat and crippled but the Australian destroyer HMAS Nestor assisted her safe arrival to harbour and she was seaworthy again by September. The cruisers sailed ahead to disembark troops and equipment and begin their return that evening and the convoy and its destroyer escort arrived later on 24 July. All of the ships of MG 1 had managed to reach Gibraltar and the covering force was joined by the cruiser escorts and all reached Gibraltar on 27 July, An raid on 26 July by Italian midget submarines, MAS boats and aircraft on the transports in Grand Harbour failed, with the attacking force almost destroyed and 65,000 short tons (59,000 t) of supplies were landed. On 31 July, three cruisers and two destroyers sailed from Gibraltar with the troops and stores left behind on Leinster arrived on 2 August, departed the same day and reached Gibraltar on 4 August.
Operations Status I and II, Operation Propeller
Ark Royal and Furious flew off over 50 Hurricanes to Malta in Operation Status I and Status II, forty-nine arriving; several Blenheims flew direct from Gibraltar at the same time, to build up the Malta striking force to use the munitions delivered in Operation Substance. The merchantman SS Empire Guillemot reached Malta from Gibraltar in Operation Propeller and another ship completed the trip independently.
In Operation Halberd, the eastbound convoy GM 2 with nine 15 kn (17 mph; 28 km/h) merchant ships, carrying 81,000 long tons (82,000 t) of supplies and 2,600 troops from Gibraltar, was accompanied by the battleships Nelson, Rodney, Prince of Wales (all detached from the Home Fleet), Ark Royal, five cruisers, and eighteen destroyers. The British staged diversions in the eastern Mediterranean and submarines and aircraft watched Italian naval and air bases. Attacks on the convoy by the Regia Aeronautica began on 27 September, demonstrating more skill and determination than earlier encounters. An Italian torpedo bomber hit Nelson with an aerial torpedo and reduced her speed. Later air attacks were deterred by the anti-aircraft fire of the British destroyer screen. British reconnaissance aircraft reported the Italian Fleet had left harbour and was on an interception course and the British covering force, less Nelson, was sent to engage. Ark Royal launched her torpedo bombers but the Italian turned back, and the aircraft failed to make contact; at about 7:00 p.m., GM 2 reached the Narrows.
The five cruisers and nine of the destroyers continued for Malta as the covering force changed course. The British made course for Sicily, which enabled them to skirt minefields laid by the Italians in the channel between Sicily and the North African coast. During the night the moon was bright and Italian torpedo bombers managed to hit the 10,000 GRT transport Imperial Star with an aerial torpedo. Attempts to tow the ship to Malta failed; her troops were taken off and the ship was scuttled. During the morning of 28 September, the convoy came into range of Malta-based fighters. The rest of the convoy reached Malta at 1:30 p.m. and landed 85,000 short tons (77,000 t) of supplies. Halberd was the last convoy operation of 1941.
Operations Callboy and MG 3
On 16 October, Force H covered Operation Callboy, another Club Run by Ark Royal, to fly off thirteen Swordfish and Albacore torpedo bombers for Malta, delivered to Gibraltar by Argus. On 12 October, the cruisers HMS Aurora and Penelope had sailed from Scapa Flow for Malta and were joined by the destroyers HMS Lance and Lively of Force H at Gibraltar, reaching the island on 21 October. The squadron was named Force K (reviving a title used in 1939) for operations against the Italian supply route to North Africa. Operation MG 3 was a convoy planned to despatch the Halberd merchant ships from Malta but the ships sailed in succession. Two departed on 16 October but one ship had to turn back with engine trouble. The second ship was covered by the fleet movements of Operation Callboy which reached the flying off point on 17 October and arrived on 19 October, having dodged a torpedo bomber attack. Two cruisers and two destroyers of Force H loaded equipment and ammunition for Malta as soon as they got back to Gibraltar and sailed again on 20 October and arrived at Grand Harbour in Malta the next day. Two of the empty ships from Malta sailed on 21 October and arrived at Gibraltar despite air attacks and the ship with engine trouble left Malta again on 22 October to be watched over by Catalina flying boats but failed to arrive; an Italian radio broadcast claimed a British merchant ship, which was taken to mean the ship bound for Gibraltar. The fourth ship sailed on 24 October but was attacked by an Italian aircraft and recalled, having been spotted so quickly.
Force K of two cruisers and two destroyers sailed from Malta on 8 November and sank the merchant ships of an Axis convoy off Cape Spartivento. On 10 November, Ark Royal and Argus sailed from Gibraltar and flew off thirty-seven Hurricanes for Malta, thirty-four arriving on the island; seven Blenheims flew direct from Gibraltar. On 13 November, Ark Royal was torpedoed and sank the next day, 25 nmi (29 mi; 46 km) from Gibraltar.
Operation Astrologer (14–15 November 1941), an attempt to supply Malta by two unescorted freighters, Empire Pelican and Empire Defender disguised as neutral Spanish then French ships. Empire Pelican passed Gibraltar on 12 November and sailed close to the Moroccan, Algerian and Tunisian coasts but was spotted by Italian aircraft at early on 14 November south of Galite Islands and sunk by torpedo bombers. Empire Defender was sunk at sunset the nest day in the same place; Astrologer was the last attempt to send merchant ships to Malta from the west for six months.
Operations Chieftain and Landmark
During Operation Crusader in the Western Desert, a bogus Malta convoy GM 3, was assembled for Operation Chieftain, an attempt to divert Axis aircraft away from the land battle. Five merchantmen, the oiler Brown Ranger a sloop, a destroyer and three corvettes left Gibraltar on 16 November, the freighters to turn back after dark and return independently, while the escorts continued for a two-day anti-submarine sweep. One of the corvettes had engine trouble, sailed late and sank a German U-boat. Force K contributed to the deception by sailing westwards from Malta to simulate a rendezvous with GM 3 then reversing course overnight to reach Malta again on 19 November. A second diversion force left Malta in Operation Landmark early on 21 November, feigning a voyage to Alexandria to escort four merchant ships and for added verisimilitude the battle squadron at Alexandria sailed as if to meet the ships from Malta. The German B-Dienst (Observation Service) learnt from British naval signals that Force K was at sea but an Italian convoy and escorts were ordered to port rather than risk battle.
Operations MF 1 and MD 1
To alleviate a fuel oil shortage on Malta, MV Breconshire was escorted from Malta on 5 December by a cruiser and four destroyers of Force K in Operation MF 1 towards Alexandria; next day, a cruiser and two destroyers left Alexandria. During the evening of 6 December the cruiser and two destroyers returned to Malta and two destroyers carried on with Breconshire, meeting the cruiser and two destroyers from Alexandria at dawn on 7 December. Two destroyers went on to Malta and Breconshire continued to Alexandria accompanied by the cruiser and its two destroyers, reaching Alexandria on 8 December, less the cruiser which was detached to help a sloop damaged by air attack of Tobruk. Breconshire was filled with 5,000 long tons (5,100 t) of boiler oil and every space was filled with supplies. On 15 December, MD 1 began when Breconshire sailed for Malta with three cruiser and eight destroyer escorts. During the night Breconshire was slowed by engine trouble and on 16 December the force headed west in daylight without zig-zagging. After dark a cruiser and two destroyers turned back and made spurious wireless broadcasts to simulate the battle fleet at sea. Destroyers left Malta on 16 December and at 6:00 p.m. Force K comprising two cruisers and two destroyers sailed to meet Breconshire and escort it into Grand Harbour.
During the afternoon, an Italian battleship convoy was spotted and every seaworthy ship at Malta was ordered out to bring in Breconshire. Only one cruiser and two destroyers were operational but they met the oncoming force before dawn on 17 December and the ships made a circle round Breconshire; the Luftwaffe and Regia Aeronautica attacked through the afternoon with bombs and torpedoes. As night was falling, three Italian battleships two cruisers and ten destroyers appeared and Breconshire and two escorts were diverted to the south-west as the rest of the British ships turned towards the Italian fleet. With the escorts between the Italians and Breconshire, the ship was handed over to Force K as it arrived and set a smoke screen. The opposing ships diverged in the dark and Force K turned for Malta with Breconshire; the rest of the ships returned to Alexandria and the Italian freighters reached Libya. Force K and Breconshire spent 18 December under air attack, until Malta Hurricanes arrived in the afternoon and at around 3:00 p.m. the ships arrived in Malta.
Operation MF 2
On 5 January, the fast supply ship HMS Glengyle was escorted from Alexandria by the 15th Cruiser Squadron (Force B, Rear Admiral Philip Vian), comprising the Dido-class light cruisers Naiad, Dido and Euryalus and six destroyers and exchanged with Breconshire from Malta. The cruisers served as a bluff, in the absence of bigger ships capable of challenging a sortie by the Regia Marina. Breconshire had sailed from Malta on 6 January escorted by four destroyers of Force C; the two forces met on 7 January and Force C with Glengyle reached Malta on 8 January, Force B with Breconshire arriving at Alexandria the next day.
Operation MF 3
On 16 January the convoys MW8A and MW8B with two ships each, sailed from Alexandria in Operation MF3, accompanied by the Anti-aircraft cruiser HMS Carlisle and two destroyer divisions. The 15th Cruiser Squadron sailed on 17 January to join the escort force for both convoys. Force K (still short Aurora) departed Malta to rendezvous with the convoy on 18 January. The 6,655-ton Thermopylae of MW8A developed mechanical faults and was diverted to Benghazi but was severely damaged by bombing en route and had to be scuttled. On 17 January, the destroyer HMS Gurkha was torpedoed by U-133; the Dutch destroyer HNLMS Isaac Sweers towed her clear of blazing oil, allowing most of her crew to be rescued before the ship sank. The three remaining freighters reached Malta, air attacks on the ships being intercepted by fighters from No. 201 (Naval Co-operation) Group based in Cyrenaica, the convoy and escorts' anti-aircraft guns; once the convoy was in range. Hurricanes from Malta also provided air cover and the ships docked on 19 January. As soon as it was certain that the Italian fleet was still in port, the 15th Cruiser Squadron and its destroyers turned for Alexandria and arrived on 20 January. On 26 January, in a similar operation, Breconshire and escorts from Alexandria met two ships which had sailed from Malta on 25 January transporting service families from Malta with escorts from Force K, which escorted Breconshire back to the island on 27 January; on 28 January, the force from Alexandria returned with the two ships from Malta.
Operation MF 5
During German air raids on Malta on 12 February, HMS Maori was sunk at her moorings in Grand Harbour. On the same day, a three ship convoy MW 9, escorted by Carlisle and eight destroyers, sailed from Alexandria in Operation MF5; several hours later, two cruisers from 15th Cruiser Squadron, escorted by eight destroyers, sortied. On 13 February, Breconshire, accompanied by cruiser and six destroyers, departed with three ships in ballast, bound for Alexandria. On 14 February, SS Clan Campbell was bombed and forced to seek shelter in Tobruk, Clan Chattan was bombed, caught fire and scuttled in the afternoon; Rowallan Castle was near-missed, disabled and taken under tow but scuttled by Lively after it was realised she could not reach Malta before dark: the escort had been warned the Italian battleship Caio Duilio had sailed from Taranto to intercept the convoy.
On 6 March, Operation Spotter, a Club Run by the aircraft carriers Eagle and Argus flew off the first 15 Spitfire reinforcements for Malta. An earlier attempt had been abandoned but the right external ferry tanks were fitted; seven Blenheims flew direct from Gibraltar. On 10 March, the Spitfires flew their first sorties against a raid by Ju 88s escorted by Bf 109 fighters.
Operation MG 1
Operation MG 1 began with convoy MW 10 of four ships sailing from Alexandria at 7:10 a.m. on 20 March, each with a navy liaison party and Defensively equipped merchant ship (DEMS) gunners, supplemented by service passengers. The convoy was escorted by Force B, the cruisers HMS Cleopatra, Dido, Euryalus, the anti-aircraft cruiser Carlisle and the six ships of the 22nd Destroyer Flotilla. The 5th Destroyer Flotilla sailed from Tobruk on an anti-submarine sweep, before joining the convoy on 21 March. Clan Campbell struggled to keep up because of engine trouble and the convoy timetable was not met. Several British submarines participated near Messina and Taranto to watch for Italian ships. Long Range Desert Group parties were to attack the airfields at Martuba and Tmimi in Cyrenaica as RAF and FAA aircraft bombed them to ground Ju 88 bombers; 201 Group RAF provided air cover and reconnaissance of the convoy route. A club run, Operation Picket was to use Argus and Eagle, with Force H as a decoy, but the Spitfire ferry tanks were found to be defective and the operation was called off.
On 22 March, when MW 10 was through Bomb Alley, news arrived that an Italian squadron had sailed and from 10:35 a.m. – 12:05 p.m. five Italian torpedo bomber attacks were made but with no hits. In the afternoon, German and Italian air attacks began, with bombs and torpedoes, again to no effect. Smoke was seen at 2:10 p.m. and the escorts moved to intercept in rough seas as the convoy was hidden by a smoke screen. Italian cruisers commenced fire, then turned to lure the British cruisers towards Littorio; the British did not take the bait. The exchange was the beginning of the Second Battle of Sirte and Axis aircraft concentrated on the convoy, which manoeuvred so effectively that no ship was hit, but the ships and close escort fired much of their ammunition. During the battle near the convoy, the escorts kept laying smoke screens and the Italians came within 8 nmi (9.2 mi; 15 km) as Force B dodged around in the smoke, attacking at every opportunity.
German air attacks continued and Force B turned for Alexandria, very short of fuel as Force K joined the convoy for the last leg. The convoy had been ordered to disperse, three ships diverting southwards and Clan Campbell making straight for Grand Harbour, the diversions being calculated to bring the ships back together just short of Malta by daylight on 23 March. The detours were a mistake and Pampas was hit by a bomb during the morning but kept going, reaching Malta. Talabot was also frequently attacked but arrived undamaged, except from some small bombs dropped by a Bf 109 fighter-bomber. Clan Campbell was sunk 20 nmi (23 mi; 37 km) from Malta and Breconshire, after being taken in tow by destroyers and tugs several times, reached Marsaxlokk harbour on 25 March. Unloading of the ships was very slow and Luftwaffe attacks on 26 March sank Breconshire in the evening and continued bombing Valletta harbour into the night. Talabot and Pampas were set on fire before unloading, only 4,952 short tons (4,492 t) of the 29,500 short tons (26,800 t) of supplies were landed and several destroyers were seriously damaged.
On 22 March, a Club Run by Argus and Eagle covered by Force H sailed from Gibraltar to deliver Spitfires to Malta and to divert attention from MG 1. Two Italian submarines spotted the British ships and one fired torpedoes at Argus with no effect but the operation was cancelled when the long range fuel tanks of the Spitfires were found to be defective. The operation was repeated on 27 March and sixteen Spitfires were flown off for Malta, the ships returning to Gibraltar on 30 March.
The island had ceased to be an effective offensive base and Axis convoys were mostly untroubled. Several submarines and destroyers were bombed and sunk in harbour and naval units were ordered to leave for Gibraltar or Alexandria. Not all arrived safely. Forty-seven Spitfires were flown off to Malta from the American carrier USS Wasp, escorted by the battlecruiser Renown, cruisers HMS Cairo and Charybdis and six British and US destroyers. Most of the aircraft were destroyed on the ground by bombing.
Operations Bowery and LB
On 20 May, SS Empire Conrad departed from Milford Haven, Wales with a cargo of 32 Spitfires in cases. The aircraft were all Spitfire Mk VcT. Also on board were the ground crew who were to assemble them, a total of over 110 men. Empire Conrad was escorted by the 29th ML Flotilla and the corvette HMS Spirea. The convoy was later joined by the Minesweepers HMS Hythe and Rye. Empire Conrad arrived at Gibraltar on 27 May. The aircraft were transferred to the aircraft carrier HMS Eagle where they were assembled. On 2 June, Eagle departed from Gibraltar escorted by the cruiser Charybdis and destroyers HMS Antelope, Ithuriel, Partridge, Westcott and Wishart. On 3 June, the aircraft were flown off Eagle, bound for Malta. Twenty-eight arrived safely, with the other four being shot down en route.
Operation Julius (Harpoon and Vigorous)
The arrival of more Spitfires from Eagle and the transfer of German aircraft to the Russian Front eased the pressure on Malta but supplies were needed. Operation Julius was planned to send convoys simultaneously from both ends of the Mediterranean. The ships for Operation Harpoon sailed from Britain on 5 June and entered the Mediterranean on the night of 11/12 June. Force H had participated in the Allied invasion of Madagascar (Operation Ironclad) and escorts were collected from several stations to obtain one battleship, the aircraft carriers Eagle and Argus, three cruisers and eight destroyers for the escort and covering force to the narrows, the close escort into Malta comprising the anti-aircraft cruiser Cairo, nine destroyers, four fleet minesweepers and six motor launches equipped for minesweeping. Once the convoy of three British, one Dutch and two US freighters carrying 43,000 long tons (44,000 t) of supplies had been swept through the Axis minefields, the minesweepers were to remain at Malta. The fast minelayer HMS Welshman [40 kn (46 mph; 74 km/h)] which looked similar to Vichy French warships, was to sail ahead with ammunition and stores; a fleet oiler RFA Brown Ranger with an escort force was to sail near the convoy route, ready to refuel ships as necessary and four submarines patrolled Axis ports.
The ships from Gibraltar and Alexandria were intended to arrive on consecutive days. Axis naval and air forces made a corresponding maximum effort, the first attacks beginning in the morning of 12 June; one cruiser was badly damaged and one merchantman sunk. On 15 June an Italian cruiser force engaged the close escort and as Cairo and the small destroyers made smoke, the fleet destroyers attacked the Italian ships. Two of the fleet destroyers were soon disabled the remaining three managed to hit an Italian destroyer and were then joined by the cruiser and the four smaller destroyers. Dive-bombers attacked the convoy soon after and one merchant ship was sunk and another damaged and taken in tow. Near noon, another air attack damaged another merchant ship and it and the ship in tow were sunk to increase the speed of the remaining two ships, which under cover of the Malta Spitfires which defeated several more air attacks, arrived with 15,000 short tons (14,000 t) of supplies; the destroyers (HMS Bedouin and the Polish Kujawiak were also sunk. A convoy of eleven merchant ships from Haifa, Palestine and Port Said, Egypt sailed in Operation Vigorous and was attacked by aircraft, torpedo boats and submarines for four days, threatened by a strong Italian battle fleet and was turned back to Alexandria. The cruiser (HMS Hermione), the destroyers (HMS Hasty, Airedale and Nestor were sunk along with two merchantmen.
The fast minelayer Welshman had been sent back to Britain for maintenance and sailed on 9 July for Gibraltar carrying powdered milk, cooking oil, fats and flour, soap and minesweeping stores. The ship left for Malta on 14 July along with an aircraft carrier two cruisers and five destroyers, Eagle flew off 31 Spitfires on 15 July. Welshman made an independent run close to the Algerian coast but was shadowed by Axis aircraft and then attacked by fighter-bombers, bombers and torpedo bombers until dusk. Welshman reached Malta on 16 July and left again on 18 July, having unloaded under cover of the Spitfires from the Club Run. Bad weather enabled the ship to evade Italian submarine ambushes and a cruiser squadron, the ship not being sighted until 19 July; the ship survived attacks by bombers and torpedo bombers to return to Gibraltar on 21 July. The supplies delivered to Malta enabled the submarine Upholder to return to Malta and resume offensive patrols from the island.
Eagle sailed from Gibraltar with two destroyers and five destroyers on 20 July, Eagle being missed by a salvo of four torpedoes from the Italian submarine Dandolo and on 21 July another 28 Spitfires were flown off for Malta.
As supplies on Malta dwindled, particularly of aviation fuel, the largest convoy to date was assembled at Gibraltar for Operation Pedestal. It consisted of 14 merchant ships, including the large oil tanker SS Ohio. These were protected by powerful escort and covering forces, totalling forty-four warships, including the aircraft carriers Eagle, Indomitable and Victorious and battleships Nelson and Rodney. A diversionary operation was staged from Alexandria. The convoy was attacked fiercely. Three transports reached Malta on 13 August and another on 14 August. Ohio arrived on 15 August, heavily damaged by air attacks and being towed by destroyers HMS Penn and Ledbury. The rest were sunk. Ohio later broke in two in Valletta Harbour but not before much of her cargo had been unloaded. The aircraft carrier Eagle, cruisers Cairo and Manchester and the destroyer HMS Foresight were sunk and there was serious damage to other warships; Italian losses were two submarines and damage to two cruisers.
This convoy, especially the arrival of Ohio, was seen as divine intervention by the people of Malta. August 15 is celebrated as the feast of the Assumption of Mary and many Maltese attributed the arrival of Ohio into Grand Harbour as the answer to their prayers. It had been agreed by military commanders at the time that if supplies became any lower, they would surrender the islands (the actual date, deferred as supplies were received, was referred to as the target date). At that time, to stretch the supply of flour, the Maltese mixed flour with potato peelings, making a sort of brown bread. The situation became so dire that bread became white again when potato peelings ran out. Pedestal delivered 12,000 long tons (12,000 t) of coal, 32,000 long tons (33,000 t) freight and 11,000 long tons (11,000 t) of oil on Ohio of the 121,000 long tons (123,000 t) on the ships when the convoy began. The commodities landed were enough for Malta to last until mid-November. The 568 survivors of the Pedestal convoy were evacuated, 207 men on three destroyers to Gibraltar and the remainder by submarine and aircraft.
On 16 August, a cruiser and twelve destroyers escorted Furious to the area south of Formentera in the south-west of the Balearic Islands, which flew off 32 Spitfires of which one crashed on take-off and two turned back, 29 Spitfires reaching Malta that afternoon.
Attacks on Axis convoys to North Africa using the fuel delivered by Ohio deprived the Axis armies of 300,000 long tons (300,000 t) of supplies. The submarine HMS Talisman was lost on a supply run from Gibraltar, either stranded in a minefield or depth-charged by Italian torpedo boats north-west of Malta on 17 September.
Magic Carpet rides by submarine reached Malta on 2 October (Rorqual), 3 October (Parthian), and 6 October (Clyde), with petrol and other stores, departing for Beirut on 8 October carrying survivors from Pedestal.
A continuous flow of new Spitfires to Malta had become necessary after the Axis air forces resorted to attacks by fighter-bombers; in another Club Run from 28 to 30 October, two cruisers and eight destroyers escorted Furious which flew off 29 Spitfires for Malta, of which two returned with engine trouble. Ten Italian submarines were patrolling but were not able to attack and Axis aircraft were held off until the afternoon of 29 October, when a Ju 88 managed to drop a bomb which landed 600 ft (180 m) behind Furious.
Operations Stone Age and Crupper
An attempt in early November to sneak an independently routed, disguised freighter to Malta from Alexandria failed; on Operation Crupper, the disguised merchant ships Ardeola (2,609 tons) and Tadorna (1,947 tons) from Gibraltar, were captured and interned at Bizerta while passing through Vichy territorial waters. The fast minelayer Welshman made a dash from Gibraltar with a cargo of dried food and torpedoes during the Allied landings in French North Africa (Operation Torch), Manxman and six destroyers sailed from Alexandria on 11 November; both efforts succeeded. On 17 November, convoy MW 13 (two US, one Dutch, and one British merchant ship, carrying 35,000 short tons (32,000 t) of supplies) departed Alexandria, escorted by three cruisers of the 15th Cruiser Squadron; from 18 November, this was reduced to ten destroyers. Axis air attacks began and after the main escort had detached at 6:00 p.m., the cruiser HMS Arethusa was torpedoed and set on fire, 155 men being killed and the ship having to be towed stern-first through gales to Alexandria. Many of the air attacks were intercepted by Allied fighters flying from desert airfields and on 20 November, MW 13 arrived, escorted by Euryalus and ten Hunt-class destroyers. By 25 November, the ships had landed an adequate quantity of aviation fuel and Magic Carpet rides were cancelled. On 20 November, the minelayer HMS Adventure sailed from Plymouth to Gibraltar with 2,000 depth charges for Malta and made a repeat run in December. The success of Stone Age relieved the siege of Malta, albeit by a narrow margin because the lack of military stores and food for the population would have been exhausted by December. Malta submarines were freed to increase the number of offensive patrols, Force K was re-established with Dido, Euryalus and four destroyers, a Motor Torpedo Boat flotilla arrived and 821 Squadron Fleet Air Arm (FAA) with Fairey Albacores, began operations from the island.
In Operation Portcullis, the five ships of convoy MW 14 arrived from Port Said with 55,000 short tons (50,000 t) of supplies, the first convoy to arrive without loss since 1941. Nine more ships arrived in convoys MW 15 to MW 18, delivering 18,200 short tons (16,500 t) of fuel and another 58,500 short tons (53,100 t) of general supplies and military stores by the end of December; thirteen ships returned to Alexandria as convoys ME 11 and ME 12. Increased rations to civilians helped to stave off the general decline in health of the population, which had led to an outbreak of poliomyelitis.
December 1942 – January 1943
Portcullis was the last direct convoy to Malta; in Operations Quadrangle A, B, C and D, pairs of ships to Malta joined with ordinary west-bound convoys then rendezvoused with escorts from Force K, arriving with no loss. In Operation Quadrangle A, convoy MW 15 of two ships was a side convoy from the new Port Said to Benghazi service. When the main convoy arrived off Barce in Libya, the ships for Malta rendezvoused with eight destroyer escorts and empty ships from the island. The ships exchanged escorts for the return voyage to Grand Harbour, MW 15 arriving on 10 December. Operation Quadrangle B covered convoy MW 16 of one tanker escorted by six destroyers and a minesweeper. Four ships of MW 13 were formed into convoy MW 12 and nine destroyers departed Grand Harbour on 17 December. Quadrangle B was attacked by JU 88s the next day to no effect. Several escorts handed over MW 12 at Barce to ships from Alexandria and took over convoy MW 17, two freighters in Operation Quadrangle C to Malta. Convoy ME 13 was omitted and convoy ME 14 with four empty ships sailed from Malta on 28 December with five destroyers. In December, 58,500 long tons (59,400 t) of general cargo and 18,200 long tons (18,500 t) of fuel oil was delivered. Convoy MW 18 with a tanker and a merchant ship departed from Alexandria in Operation Quadrangle D with six destroyer escorts, arriving at Malta on 2 January 1943.
Convoy MW 19 left Alexandria on 7 January 1943 with five freighters and a tanker with nine destroyers and survived an attack by torpedo bombers at dusk on 8 January. During a night attack, a merchantman and a destroyer were near-missed and a destroyer evaded a torpedo and on 9 January a storm slowed the tanker and the convoy missed the meeting with Force K and later made rendezvous with three Malta destroyers. As the storm abated the ships gathered speed and for most of the run to Malta Beaufighters provided air cover, one being vectored onto a He 111 during 11 January, which was attacked and driven off, the convoy arriving at Malta during the evening.
There were 35 large supply operations to Malta from 1940 to 1942. Operations White, Tiger, Halberd, MF5, MG1, Harpoon, Vigorous and Pedestal were turned back or suffered severe losses from Axis forces. There were long periods when no convoy runs were even attempted and only a trickle of supplies reached Malta by submarine or fast warship. The worst period for Malta was from December 1941 to October 1942, when Axis forces had air and naval supremacy in the central Mediterranean. Operation Pedestal from 3 to 15 August 1942 was strategically successful in that it revived Malta as an offensive base, despite the cost in warship and merchant ship losses. Offensive operations from Malta sank Axis ships carrying 300,000 long tons (300,000 t) of supplies to the Italian and German forces in North Africa. From 31 August to 2 September the Axis forces were stopped at Alam Halfa in Egypt, defeated from 23 to 24 October and on 8 November the Allies began Operation Torch in the western Mediterranean. In early 1943, supply ships brought the usual cargoes to Malta and the equipment and stores for Operation Husky, the invasion of Sicily.
From June 1940 to December 1943, about 1,600 civilians and 700 soldiers were killed on Malta. The RAF lost about 900 men killed, 547 aircraft on operations and 160 on the ground and Royal Navy losses were 1,700 submariners and 2,200 sailors; about 200 merchant navy men died. Of 110 voyages by merchant ships to Malta 79 arrived, three to be sunk soon after reaching the island and one ship was sunk on a return voyage. Six of seven independent sailings failed, three ships being sunk, two were interned by Vichy authorities and one ship turned back. The Mediterranean Fleet lost a battleship, two aircraft carriers, four cruisers, a fast minelayer, twenty destroyers and minesweepers and forty submarines. Many small ships were sunk and many surviving ships were damaged.
- An Afrika Korps convoy (the Tarigo convoy) of the German ships Aegina, Arta, Adana and Iserlhon, with 3,000 troop reinforcements on board, the Italian Sabaudia loaded with ammunition and three Italian destroyer escorts was sunk by the destroyers Jervis, Janus, Nubian and Mohawk, near the Kerkennah Islands off Tunisia; Mohawk was also sunk but the success showed the value of Malta as an offensive base. Churchill ordered that the Italian supply route to Tripoli be cut off and even suggested using the battleship Barham to block the harbour.
- During the night, two of the ships hit mines, Empire Song blowing up and the other ship being damaged but continuing; the four surviving ships arrived at Alexandria.
- Empire Guillemot had sailed close to the African shore but on 23 October was caught by three Italian bombers and sunk. The crew tried to sail on to Gibraltar in two lifeboats but were eventually forced ashore and the survivors were interned by the Vichy French.
- Force K sank seven merchantmen and one of its destroyer escorts; the force was back at Malta by the afternoon of 9 November and the submarine Upholder from Malta sank another destroyer.
- The Dido-class cruisers were equipped with a main armament of dual-purpose QF 5.25 inch guns and had been designed for convoy protection and service in the Mediterranean.
- Carlisle had been converted to an anti-aircraft ship with eight 4-inch dual purpose guns in 1940 and had been allotted to the 15th Cruiser Squadron in May 1940.
- Merlins over Malta (Chronology of the Siege of Malta, 1940–43) states that 25,000 tons were landed, enough to sustain the population for two to three months.
