War Cabinet that no concessions should be made. With the British home islands in danger, the defence of Malta was not the priority and it was lightly protected. Only six obsolete Gloster Sea Gladiator biplanes were stationed on the island, with another six in crates when, on 10 June 1940, Mussolini declared war on the United Kingdom and France. In the 1930s, Italy had sought to expand in the Mediterranean and Africa, regions dominated by the British and French. The Allied defeat in France from May–June 1940 removed the French Navy from the Allied order of battle and tilted the balance of naval and air power in Italy's favour. Upon declaring war, Mussolini called for an offensive throughout the Mediterranean and within hours, the first bombs were dropped on Malta. After the French surrender on 25 June, Mussolini tried to exploit the situation, conducting Operazione E the Italian invasion of Egypt in September. The 10th Army was crushed in Operation Compass, a British counter-stroke, and Adolf Hitler decided to come to the aid of his ally. In February 1941, the Deutsches Afrikakorps (DAK, German Africa Corps under General Erwin Rommel) was sent to North Africa as a blocking detachment (). RAF and Royal Navy anti-shipping squadrons and submarines on Malta threatened the Axis supply line to North Africa and both sides recognised the importance of Malta in controlling the central Mediterranean. In 1940, an Italian assault on Malta stood a reasonable chance of gaining control of the island, an action giving the Italians naval and air supremacy in the central Mediterranean. The Mediterranean would have been split in two, separating the British bases at Gibraltar and Alexandria. The reluctance of the Italians to act directly against Malta throughout 1940 was strengthened by the Battle of Taranto, in which much of the Italian surface fleet was put out of action by Royal Navy Fleet Air Arm torpedo bombers. The Italians adopted an indirect approach and cut off the island. To the Italians (and later the Germans), air power was the key weapon against Malta. Italian siege (June–December 1940) Italian air actions Air power was the method chosen to attack Malta. The Regia Aeronautica began the aerial bombardment of the island from airbases in Sicily. On the first day, 55 Italian bombers and 21 fighters flew over Malta and dropped 142 bombs on the three airfields at Luqa, Hal Far and Ta
