Operation Substance was a British naval operation in July 1941 during the Second World War to escort Convoy GM 1, the first of the series from Gibraltar to Malta. [1] The convoy, escorted by Force H, was attacked by Italian submarines, aircraft and MAS boats (Motoscafo armato silurante, motor torpedo boats).
Port Chalmers carried 250 members of the Royal Artillery one light, one heavy anti-aircraft regiment and thirty field guns to strengthen the island against airborne assault. [2] Medical personnel expected to be needed in the anticipated Siege of Malta were also embarked. [3]
Force H included the battleship HMS Nelson, the battlecruiser HMS Renown, the fast minelayer HMS Manxman, the cruisers HMS Manchester, Edinburgh and Arethusa with eight destroyers and the aircraft carrier HMS Ark Royal with 21 Fairey Fulmar fighters and ferrying seven Fairey Swordfish reinforcements to Malta. [2]
The Royal Navy observed a decrease in the intensity of Regia Aeronautica (Italian Royal Air Force) attacks as the stock of torpedoes at Sardinian airfields was nearly exhausted. The ships of Convoy GM 1 sailed from the British Isles on 13 July 1941 as part of Convoy WS 9C (Winston Specials) and arrived at Gibraltar on 20 July. [4] Ships of the Mediterranean Fleet operating from Alexandria began making much radio traffic to divert attention from Gibraltar towards preparations for a big operation in the eastern Mediterranean. Eight Allied submarines were deployed off Italian naval bases but Supermarina , the Italian naval headquarters, assumed the convoy was Ark Royal flying-off replacement aircraft to Malta and chose to remain in port. Leinster ran aground while leaving Gibraltar on 21 July and had to return to port. The Perla-class submarine Diaspro found the convoy on 22 July and launched torpedoes which narrowly missed Renown and HMAS Nestor. [2]
The convoy was attacked by nine Savoia-Marchetti SM.79 torpedo bombers coordinated with five CANT Z.1007 medium bombers. Four Fulmars met the torpedo attack head-on and shot down a SM.79 but another SM.79 dropped a torpedo before it was shot down, which hit Manchester. Ark Royal launched seven more Fulmars which were unable to engage the high level bombers before they bombed but these failed to hit the merchant ships; three Fulmars were shot down. A later attack by two SM.79s sank Fearless killing 35 of her crew. Another bombing near-missed Firedrake causing severe damage and the destroyer had to be towed back to Gibraltar. Bristol Beaufighters from Malta reinforced the Ark Royal Fulmars. [2]
Cossack detected the torpedo-boats MAS 532 and MAS 533 approaching the convoy after dark but was unable to prevent them from torpedoing SS Sydney Star (11,000 GRT) at around 03:00 on 24 July. The merchant ship, carrying 484 army officers and men as passengers along with the crew, came to a dead stop as it took on water. Fearing that the ship's pumps were unable to cope with the damage, the captain requested evacuation of the troops. Nestor came alongside and took on board approximately 500 men via gangplank and Jacob's ladder, leaving the captain and a skeleton crew on board. The captain later estimated that his ship had taken on 7,000 long tons (7,100 t) of water. Nestor towed it to Malta, arriving at Grand Harbour shortly after 08:00. [2] [5] [6]
Seven unloaded ships sailed from Malta in Convoy MG 1 on 23 July to be convoyed back to Gibraltar by Force H. [1] One was damaged by a torpedo bomber on the voyage west. Ark Royal lost six Fulmars defending Convoy MG 1 and the Malta-bound ships from Gibraltar and at least 12 Axis aircraft were destroyed by FAA fighters and the AA guns of the Royal Navy. [7] [a] The six merchant ships of Convoy GM 1 arrived in Malta on 24 July where they were observed by a CANT Z.506 reconnaissance seaplane, escorted by 42 Macchi C.200 fighters. Malta sent 22 Hurricane fighters to intercept, which shot down three of the escort without loss. [2]
The Raid on Grand Harbour, an audacious attack by the elite Decima MAS , using explosive motor-boats (MTM) and manned torpedoes early on 26 July was thwarted by Radar and Ultra, ending in disaster for the Italians. [2]
HMS Ark Royal was an aircraft carrier of the Royal Navy that was operated during the Second World War.
Force H was a British naval formation during the Second World War. It was formed in late-June 1940, to replace French naval power in the western Mediterranean removed by the French armistice with Nazi Germany. The force occupied an odd place within the naval chain of command. Normal British practice was to have naval stations and fleets around the world, whose commanders reported to the First Sea Lord via a flag officer. Force H was based at Gibraltar but there was already a flag officer at the base, Flag Officer Commanding, North Atlantic. The commanding officer of Force H did not report to this Flag Officer but directly to the First Sea Lord, Admiral of the Fleet Sir Dudley Pound.
Operation Pedestal, known in Malta as Il-Konvoj ta' Santa Marija, was a British operation to carry supplies to the island of Malta in August 1942, during the Second World War.
The Battle of Cape Spartivento, known as the Battle of Cape Teulada in Italy, was a naval battle during the Battle of the Mediterranean in the Second World War, fought between naval forces of the Royal Navy and the Italian Regia Marina on 27 November 1940.
HMS Sheffield was one of the Southampton sub-class of the Town-class cruisers of the Royal Navy. Completed in 1937, she was active in all major naval European theatres of the Second World War, in the Atlantic Ocean, the Mediterranean Sea and the Arctic Ocean. Sheffield assisted in the sinking of both German battleships sunk at sea; in the Last battle of Bismarck she directed torpedo aircraft to Bismarck, and during the Battle of the North Cape she took part in the shadowing of Scharnhorst.
The Battle of the Mediterranean was the name given to the naval campaign fought in the Mediterranean Sea during World War II, from 10 June 1940 to 2 May 1945.
Operation Collar was a small, fast three-ship convoy during the Second World War. The convoy left Britain on 12 November 1940 and passed Gibraltar on 24 November, escorted by two cruisers, two ships for Malta and one bound for Alexandria. Numerous other operations took place partly as diversions and the Italian Fleet sailed to attack British ships, leading to the inconclusive Battle of Cape Spartivento on 27 November. The two merchant ships reached Malta on 26 November.
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. Malta was a base from which British sea and air forces could attack ships carrying supplies from Europe to Italian Libya. Britain fought the Western Desert Campaign against Axis armies in North Africa to keep the Suez Canal and to control Middle Eastern oil. The strategic value of Malta was so great the British risked many merchant vessels and warships to supply the island and the Axis made determined efforts to neutralise the island as an offensive base.
HMS Legion was an L-class destroyer of the Royal Navy. She entered service during the Second World War, and had a short but eventful career, serving in Home waters and the Mediterranean. She was sunk in an air attack on Malta in 1942. The ship had been adopted by the British civil community of the Municipal Borough of Cheltenham, Gloucestershire in November 1941.
Operation Excess was a series of British supply convoys to Malta, Alexandria and Greece in January 1941. The operation was the first to encounter Luftwaffe anti-shipping aircraft over the Mediterranean Sea. All the convoyed freighters reached their destinations. The destroyer Gallant was disabled by Italian mines and Axis bombers severely damaged the cruiser Southampton and the aircraft carrier Illustrious.
Operation Harpoon was one of two simultaneous Allied convoys sent to supply Malta in the Axis-dominated central Mediterranean Sea in mid-June 1942, during the Second World War. Operation Vigorous was a west-bound convoy from Alexandria and Operation Harpoon was an east-bound convoy operation from Gibraltar.
Operation Vigorous was a British operation during the Second World War, to escort supply Convoy MW 11 from the eastern Mediterranean to Malta, which took place from 11 to 16 June 1942. Vigorous was part of Operation Julius, a simultaneous operation with Operation Harpoon from Gibraltar and supporting operations. Sub-convoy MW 11c sailed from Port Said (Egypt) on 11 June, to tempt the Italian battlefleet to sail early, use up fuel and be exposed to submarine and air attack. Convoy MW 11a and Convoy MW 11b sailed next day from Haifa, Port Said and Alexandria; one ship was sent back because of defects. Italian and German (Axis) aircraft attacked Convoy MW 11c on 12 June and a damaged ship was diverted to Tobruk, just east of Gazala. The merchant ships and escorts rendezvoused on 13 June. The British plans were revealed unwittingly to the Axis by the US Military Attaché in Egypt, Colonel Bonner Fellers, who reported to Washington, D.C. in "Black"-coded wireless messages; it was later discovered that the Black Code had been broken by the Servizio Informazioni Militare.
Operation Halberd was a British naval operation that took place on 27 September 1941, during the Second World War. The British were attempting to deliver a convoy from Gibraltar to Malta. The convoy was escorted by several battleships and an aircraft carrier, to deter interference from the Italian surface fleet, while a close escort of cruisers and destroyers provided an anti-aircraft screen.
The Battle of the Duisburg Convoy was fought on the night of 8/9 November 1941 between an Italian convoy, its escorts and four British ships. The convoy was named BETA by the Italian naval authorities and carried supplies for the Italian Army civilian colonists and the Afrika Korps in Italian Libya.
The Action off Cape Passero, was a naval engagement in the Second World War between the British light cruiser HMS Ajax, three torpedo boats and seven destroyers of the Italian Regia Marina, in the central Mediterranean, to the south-east of Sicily, on the night of 11/12 October 1940.
Operation MB8 was a British Royal Navy operation in the Mediterranean Sea from 4 to 11 November 1940. It was made up of six forces comprising two aircraft carriers, five battleships, 10 cruisers and 30 destroyers, including much of Force H from Gibraltar, protecting four supply convoys. It consisted of Operation Coat, Operation Crack, Convoy MW 3, Convoy ME 3, Convoy AN 6 and the main element Operation Judgement.
The Action in the Strait of Otranto [also the Battle of the Strait of Otranto (1940)] was the destruction of an Italian convoy on 12 November 1940 during the Battle of the Mediterranean in the Second World War. It took place in the Strait of Otranto in the Adriatic Sea, between the Royal Navy and the Italian Royal Navy.
HMS Lively was an L-class destroyer of the Royal Navy. She served during the Second World War, and was sunk in the Mediterranean in an air attack on 11 May 1942.
HMS Lightning was an L-class destroyer of the Royal Navy. She was launched on 22 April 1940 and sunk on 12 March 1943 by German Motor Torpedo Boat S-55.
Operation Hurry was the first British operation in a series that have come to be known as Club Runs. The goal of the operation was to fly twelve Hurricane Mk I fighters from HMS Argus to Malta, guided by two Blackburn Skuas. Force H, based in Gibraltar, took the opportunity to raid Elmas airfield in Sardinia and conduct a deception operation with HMS Enterprise. The Mediterranean Fleet conducted diversions in the eastern Mediterranean and the Aegean Sea.
