Operation Excess was a series of British supply convoys to Malta, Alexandria and Greece in January 1941. The operation encountered the first presence of Luftwaffe anti-shipping aircraft in the Mediterranean Sea. All the convoyed freighters reached their destinations. However, the destroyer Gallant was disabled by Italian mines; and Axis bombers severely damaged the cruiser Southampton and the aircraft carrier Illustrious.
Italy's declaration of War on 10 June 1940 brought World War II to the Mediterranean Sea and placed the Regia Aeronautica astride the traditional British sea route to Indian Ocean ports, while the Regia Marina roughly tripled the numbers of battleships, cruisers and submarines available to challenge British sea power. The Royal Navy had held the eastern Mediterranean and France the western Mediterranean but the Second Armistice at Compiègne removed the French navy from the alliance on 25 June 1940. From bases at Gibraltar and Alexandria, the Royal Navy attempted to convoy supplies to sustain Malta as a base in the central Mediterranean. As Italy attacked Egypt from Libya in September 1940 and Greece from Albania in October 1940, the Royal Navy maintained most of their Mediterranean Fleet at Alexandria while Force H at Gibraltar was used for raids. British successes in early November 1940 including halting the Italian offensive in Greece and disabling Italian battleships Littorio, Conte di Cavour and Caio Duilio at the Battle of Taranto provided incentive and opportunity to supply Malta and Greece.
Convoy MC 4: Four freighters waited at Gibraltar. Clan Cumming, Clan MacDonald and Empire Song carried materiel destined for Piraeus; while Essex carried 3,000 tons of seed potatoes, 4,000 tons of ammunition and 12 crated Hawker Hurricanes for Malta.
Convoy MW 5: Freighters Breconshire and Clan Macaulay waited at Alexandria with material for Malta.
Convoy ME 6: Nine freighters waited at Malta for passage to Alexandria.
Force A: HMS Warspite, Valiant, Nubian, Mohawk, Dainty, Gallant, Greyhound, Griffin, Jervis and Illustrious would sail from Alexandria to cover convoys MC 4, MW 5 and ME 6 east of the Skerki Banks.
Force D: HMS York and Orion would sail from Alexandria with Flower class corvettes Gloxinia, Peony, Hyacinth, Salvia and the replenishment oiler Brambleleaf to be joined by HMS Ajax and HMAS Perth from Souda Bay.
Force H: Convoy MC 4 would be covered from Gibraltar to the Skerki Banks by HMS Malaya, Renown, Sheffield, Faulknor, Fury, Forester, Fortune, Firedrake and Ark Royal carrying six Fairey Swordfish for Malta.
6 January 1941
Force H sailed from Gibraltar to cover convoy MC 4. Force A, Force D and convoy MW 5 with Force C sailed from Alexandria and Force B sailed from the Aegean toward Malta. Force A was located by Italian air reconnaissance that afternoon.
Force B landed its passengers in Malta and proceeded west to meet convoy MC 4. Vickers Wellingtons bombed Naples damaging Giulio Cesare with three near misses and causing the only operational Italian battleship Vittorio Veneto to retreat from the approaching convoys.
Force A was joined by Force D and HMAS Sydney 210 nmi (240 mi; 390 km) south-east of Malta, Force B joined convoy MC 4 and Convoy MC 4 and Force H were discovered by Italian aircraft and attacked by ten SM.79s from Sardinia. Two SM.79s were shot down by Fairey Fulmars from Ark Royal and later attack by 15 Fiat CR.42s carrying 100 kg bombs also failed. Force H left convoy MC 4 that afternoon after Ark Royal launched six Swordfish for the defense of Malta; Force A joined convoy MC 4 at dusk.
Italian ships from La Spezia failed to find Force H. Italian submarine Settimo and torpedo boats Circe and Vega launched torpedoes against convoy MC 4 but missed. Bonaventure and Hereward sank Vega six miles south of Pantellaria at 0830 and Circe escaped undamaged. Bonaventure was slightly damaged and two men killed; 75 per cent of her ammunition was expended in the engagement. Two of Vega's crew survived. Right after the engagement, which pushed the British convoy too much south of their route, Gallant struck a naval mine at 0835. The bow was destroyed and 65 men were killed. Mohawk took Gallant in tow toward Malta while the Force B cruisers provided protection from air attacks. Convoys MC 4 and MW 5 arrived at Malta and convoy ME 6 departed for Alexandria.
Fulmars from Illustrious shot down an Italian aircraft shadowing Force A at 0930. Valiant avoided torpedoes launched by two SM.79s approaching under the radar horizon at 1230. As the combat air patrol Fulmars dropped altitude to engage the SM.79s, Force A was attacked at 1235 by 18 He111s of KG 26 and 43 Ju87s of StG 1 and StG 2 escorted by 10 Bf110s of ZG 26. Illustrious completed launching Fulmar and Swordfish patrol aircraft as the attack developed. Illustrious was the main target and was enveloped in waterspouts and mist of exploding bombs. Some bombers diving from an altitude of 12,000 feet delayed bomb release until they pulled-out lower than the height of Illustrious' funnel. The five air patrol Fulmars had not returned from chasing the SM.79s which attacked Valiant and the four recently launched Fulmars were unable to gain altitude rapidly enough to break up the attack. The Fulmars claimed eight enemy aircraft during the bombing of Force A as they shuttled to Malta airfields to refuel and re-arm. Warspite was lightly damaged by a bomb. Illustrious was hit by five bombs, including one which failed to explode and a near miss disabled her rudder mechanism. A bomb striking a lowered elevator caused extensive hangar damage, with many casualties among aircraft maintenance personnel and destroyed nine Swordfish and five Fulmars. At 1530 Illustrious headed for Malta steering with engines. The bombing attacks continued. Seven SM.79s were discouraged by heavy anti-aircraft fire but an attack by six Italian Ju87s at 1600 scored another bomb hit and two near misses. Fourteen German Ju87s missed Valiant and Janus and a later attack by 14 He111s was similarly ineffective. Illustrious reached Malta at 2130 with 126 dead and 91 wounded.
Gallant was beached in Malta's Grand Harbor at dawn but never repaired. As Mohawk and the Force B cruisers steamed from Malta to rejoin Force A, they were surprised by 12 Ju-87R dive bombers of II/St.G.2  attacking out of the sun at 1520. Gloucester was hit by a bomb which failed to explode and Southampton was hit by two bombs killing 80 men and starting fires, requiring the ship to be scuttled 180 nmi (210 mi; 330 km) east of Malta. Force H returned to Gibraltar.
Convoy ME 6 arrived at Alexandria.
The Illustrious blitz
What Maltese called the Illustrious Blitz began when bomb stocks depleted during the attacks of 10 and 11 January, were replenished and the Axis made a concerted effort to destroy Illustrious before she could be repaired. Illustrious and Essex were hit by an air raid on 16 January. Ten Macchi C.202s, ten CR.42s and twenty Bf 110s escorted 44 Ju 87s. Bombs exploding in Grand Harbour killed numerous fish, that were collected after the raid and eaten. Illustrious was not seriously damaged but a bomb exploded in Essex's engine room killing 15 men and wounding 23 more. There was another heavy air raid on 17 January and Illustrious was again hit by an air raid on 18 January. Illustrious was not damaged by the final major attack on 19 January. Illustrious departed Malta on 23 January but her Fulmars remained for the defense of the island. Illustrious was able to complete additional repairs after reaching Alexandria on 25 January but restoration of full combat effectiveness required a trip to United States shipyards.
Fairey Fulmar fighters and AA gunners of the Royal Navy shot down at least seven aircraft on 10 January 1941, in defence of HMS Illustrious, while one Fulmar was lost. No merchantmen were lost during Excess but the Royal Navy lost one cruiser sunk and a destroyer damaged beyond repair.
