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 Battle of Taranto).^[1]

Operation Coat

Operation Coat was a reinforcement convoy from Britain to Malta, carrying troops and anti-aircraft guns. The convoy was made up of the battleship HMS Barham, heavy cruisers HMS Berwick and Glasgow and three escorting destroyers. It was covered by the aircraft carrier HMS Ark Royal, light cruiser HMS Sheffield and three more destroyers, all from Force H, out to mid-Mediterranean; three Force H destroyers would remain, the rest turning back 165 nmi (190 mi ; 306 km ) from Sicily.^[2]

Convoy MW 3

Convoy MW 3 was made up of three empty merchantmen from Malta with an Australian destroyer and the monitor HMS Terror bound for the base at Suda Bay in Crete thence to Alexandria.^[3] The convoy was escorted by the anti-aircraft cruiser HMS Coventry, accompanied by three destroyers.^[2] The 11.5 kn (13.2 mph; 21.3 km/h) convoy left Alexandria on 4 November and reached Malta on 10 November.^[4]

Convoy ME 3

Convoy ME 3 comprised four merchantmen sailing in ballast from Malta to Alexandria, under escort of the battleship HMS Ramillies, Coventry, and two destroyers.^[2] The convoy sailed from Malta on 10 November and arrived in Alexandria on 13 November.^[4]

Convoy AN 6

Convoy AN 6 consisted of four slow tankers bound for Greece from Egypt, in support of the British expedition there, escorted by a slow trawler.^[2] Shaping a similar course were reinforcements for Crete, embarked in the light cruisers HMS Ajax and HMAS Sydney as Force B, while Force C, the light cruiser HMS Orion (Vice Admiral Henry Pridham-Wippell) transported RAF supplies to Greece and inspected Suda Bay. All three would rejoin to form Force X for an 11/12 November raid on the Otranto Strait.^[2]

Operation Crack

Operation Crack was an attack on Cagliari by aircraft from Ark Royal, en route to Malta, branching off from Operation Coat.^[2]

Operation Judgement

Operation Judgement, under the command of Admiral Andrew Cunningham, was executed by aircraft from the carrier HMS Illustrious, escorted by the battleships Ramillies, Warspite, Valiant and Malaya. They met the heavy cruiser York, the light cruiser Gloucester and three destroyers, then escorting Convoy MW 3 and provided cover. A rendezvous with the Barham group from Operation Coat was to be made, with Illustrious, Gloucester, York and Berwick detaching to attack Taranto, coincident with the Force X raid. The Italians were aware of sorties from Alexandria and Gibraltar by 7 November and sent nine submarines to attack a Malta convoy (MW 3) detected on 8 November. Bombers (unsurprisingly) failed even to pinpoint the Judgement force and when Force H was detected heading back toward Gibraltar on 9 November, the Italians assumed that MW 3 had turned around, too.^[5]

Italian confusion arose when Barham, Berwick, Glasgow and their destroyers were detected 10 November off Lemnos. The correct deduction, that they had detached from the Gibraltar-bound force, was not accompanied by a correct guess they would join with Cunningham. The same day, Ramillies, Coventry and two destroyers protecting ME 3 were detected and again, bombers failed to locate them.^[6] The complexity of Operation MB8, with its forces and convoys, deceived the Italians into thinking that only normal convoying was underway. While Italian reconnaissance was characteristically bad, in the end, the Italians had only failed to keep track of Illustrious. That the Italians expected the British to behave in what was, at the time, their usual way was the cause of the mistake.^[7]

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.

HMS Hasty was an H-class destroyer built for the Royal Navy during the mid-1930s. She was assigned to the Mediterranean Fleet until the beginning of World War II. The ship transferred to Freetown, Sierra Leone, in October 1939 to hunt for German commerce raiders in the South Atlantic with Force K. Hasty returned to the British Isles in early 1940 and covered the evacuation of Allied troops from Namsos in early May 1940 during the Norwegian Campaign. She was transferred back to the Mediterranean Fleet shortly afterwards and participated in the Battle of Calabria and the Battle of Cape Spada in July 1940. The ship took part in the Battle of Cape Matapan in March and evacuated British and Australian troops from both Greece and Crete in April and May. In June, Hasty participated in the Syria-Lebanon Campaign and was escorting convoys and the larger ships of the Mediterranean Fleet for the next year. During the Second Battle of Sirte in March 1942 she defended a convoy from an Italian battleship and several cruisers. While covering another convoy from Alexandria to Malta in June 1942 during Operation Vigorous, Hasty was torpedoed by a German motor torpedo boat and was so badly damaged that she had to be scuttled.

HMS Duncan was a D-class destroyer leader built for the Royal Navy in the early 1930s. The ship was initially assigned to the Mediterranean Fleet before she was transferred to the China Station in early 1935 where she remained until mid-1939. Duncan returned to the Mediterranean Fleet just after World War II began in September 1939. She was transferred to the Home Fleet in December 1939, although she was badly damaged in a collision the following month, and required repairs that lasted until July 1940. The ship joined Force H at Gibraltar in October, escorting the larger ships and various convoys until March 1941 when she was transferred to West Africa for convoy escort duties for a few months. Duncan rejoined the 13th Destroyer Flotilla at Gibraltar in July and escorted several convoys to Malta during the rest of the year. After a refit, she briefly returned to the 13th Destroyer Flotilla before joining the Eastern Fleet in the Indian Ocean to participate in Operation Ironclad in May 1942. The ship was recalled home to be converted into an escort destroyer in late 1942.

<span class="mw-page-title-main">Battle of Cape Spartivento</span> Naval battle during the Battle of the Mediterranean

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.

The Second Battle of Sirte was a naval engagement in the Mediterranean Sea, north of the Gulf of Sidra and south-east of Malta, during the Second World War. The escorting warships of a British convoy to Malta held off a much more powerful squadron of the Regia Marina. The British convoy was composed of four merchant ships, escorted by four light cruisers, one anti-aircraft cruiser and 17 destroyers. The Italian force comprised a battleship, two heavy cruisers, one light cruiser and ten destroyers. Despite the British success at warding off the Italian squadron, the Italian fleet attack delayed the convoy's planned arrival before dawn, which exposed it to intense air attacks that sank all four merchant ships and one of the escorting destroyers in the following days.

HMS Greyhound was a G-class destroyer built for the Royal Navy in the 1930s. Greyhound participated in the Norwegian Campaign in April 1940, the Dunkirk evacuation in May and the Battle of Dakar in September before being transferred to the Mediterranean Fleet in November. The ship generally escorted the larger ships of the Mediterranean Fleet as they protected convoys against attacks from the Italian Fleet. She sank two Italian submarines while escorting convoys herself in early 1941. Greyhound was sunk by German Junkers Ju 87 Stuka dive bombers north-west of Crete on 22 May 1941 as she escorted the battleships of the Mediterranean Fleet attempting to intercept the German sea-borne invasion forces destined for Crete.

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.

The First Battle of Sirte was fought between forces of the British Mediterranean Fleet and the Regia Marina during the Battle of the Mediterranean in the Second World War. The engagement took place on 17 December 1941, south-east of Malta, in the Gulf of Sirte. It was tactically inconclusive as both forces were limited by the strategic goal of protecting a convoy of their own and as such, neither were looking to force battle.

During the Second World War, Operation Collar was a small, fast three-ship convoy that left Britain on 12 November 1940 and passed Gibraltar on 24 November, escorted by two cruisers for Malta and Alexandria.

Operation Stoneage or Operation Stone Age was an Allied convoy operation to the Mediterranean island of Malta in the Second World War. To disguise the destination of the ships, some took on their cargo at Port Sudan in the Red Sea. The four ships of Convoy MW 13 sailed from Alexandria on 16 November, escorted by cruisers, destroyers and round-the-clock air cover from captured airfields in Egypt and Cyrenaica.

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.

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 in 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 Vigorous was a British operation during the Second World War, to escort supply convoy MW11 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 MW11c 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. MW11a and MW11b sailed next day from Haifa, Port Said and Alexandria; one ship was sent back because of defects. Italian and German (Axis) aircraft attacked MW11c 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.

HMS Fury was an F-class destroyer built for the Royal Navy in the 1930s. Although assigned to the Home Fleet upon completion, the ship was attached to the Mediterranean Fleet in 1935–36 during the Abyssinia Crisis. During the Spanish Civil War of 1936–1939, she spent time in Spanish waters, enforcing the arms blockade imposed by Britain and France on both sides of the conflict. The ship escorted the larger ships of the fleet during the early stages of World War II and played a minor role in the Norwegian Campaign of 1940. Fury was sent to Gibraltar in mid-1940 and formed part of Force H where she participated in the attack on Mers-el-Kébir and the Battle of Dakar. The ship escorted numerous convoys to Malta in 1940–41 and Arctic convoys during 1942.

HMS Defender was a D-class destroyer built for the Royal Navy in the early 1930s. The ship was initially assigned to the Mediterranean Fleet before she was transferred to the China Station in early 1935. She was temporarily deployed in the Red Sea during late 1935 during the Abyssinia Crisis, before returning to her assigned station where she remained until mid-1939. Defender was transferred back to the Mediterranean Fleet just before World War II began in September 1939. She briefly was assigned to West Africa for convoy escort duties in 1940 before returning to the Mediterranean. The ship took part in the Battles of Calabria, Cape Spartivento, and Cape Matapan over the next year without damage. Defender assisted in the evacuations from Greece and Crete in April–May 1941, before she began running supply missions to Tobruk, Libya in June. The ship was badly damaged by a German bomber on one of those missions and had to be scuttled by her consort on 11 July 1941.

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.

Operation Bowery was an Anglo-American operation during the Second World War to deliver fighter aircraft to Malta, an operation known informally as a Club Run. Spitfires were needed to replace the remaining obsolete Hurricane fighters, to defend Malta from Axis air raids.

The second HMS Exmoor (L08), ex-HMS Burton, was a Hunt-class destroyer of the Royal Navy in commission from 1941 to 1945. She was a member of the second subgroup of the class, and saw service during much of World War II. She later served in the Royal Danish Navy as HDMS Valdemar Sejr.

HMS Wishart (D67) was a Modified W-class destroyer of the British Royal Navy that saw service in World War II. She spent most of her wartime career based at Gibraltar, engaged in convoy defence, but also served in various naval and military operations in the Mediterranean Sea.
