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.
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, Force H 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 from 1941, by the Luftwaffe (German Air Force) and Kriegsmarine (German Navy).
In 1942, the British assembled large flotillas of warships to escort Malta 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.
The siege of Malta eased after the Allied victory at the Second Battle of El Alamein (23 October – 11 November 1942). The Axis retreat from Egypt and Cyrenaica brought more of the seas around Malta into range of Allied land-based aircraft. In Operation Stoneage, which began after Operation Torch (8–16 November), round the clock air cover was possible and all the merchant ships reached Malta. Mediterranean convoys were resumed to supply the advancing British forces, from which ships for Malta were detached and escorted to and from the island.
Background
Malta, 1940–1941
Malta, a Mediterranean island of 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. Malta was also a base for air, sea and submarine operations against Axis supply convoys by the Royal Air Force (RAF) and Fleet Air Arm (FAA).
Central Mediterranean, 1942
Military operations from Malta and using the island as a staging post, led to Axis air campaigns against the island in 1941 and 1942. By late July, the on the island averaged wastage of and the remaining aviation fuel was only sufficient for the fighters, making it impractical to send more bombers and torpedo-bombers for offensive operations. 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 Axis (Operation Hercules) invasion plans against Malta were prepared but then cancelled on 16 June 1942.
