the German submarine U-595, which had been damaged earlier in the day by aircraft from 608 Squadron north of Oran and was unable to dive. U-595 survived, and four of the Hudsons were hit by anti-aircraft fire from the submarine, but as a result of the damage, U-595s commander deliberately ran the submarine aground. Also that day, was sunk by one of the squadron's Hudsons west of Gibraltar. On 15 November one of the squadron's aircraft bombed and sunk . The explosion badly damaged the Hudson, forcing it to ditch, with only two of the aircraft's crew being rescued. Two more U-boats were attacked that day, and another on 16 November. On 17 November, an attack by three 500 Squadron Hudsons badly damaged , which signalled surrender, but the submarine was sunk by a Fleet Air Arm Albacore torpedo bomber, which was unaware of U-331s surrender. On 17 December, one of the squadron's Hudsons attacked an Italian submarine without result, while another shot down an Italian Cant Z.1007 bomber. On 27 December, one of the squadron's Hudsons attacked the German submarine , but was badly damaged by anti-aircraft fire from the U-boat, and was forced to ditch. The squadron's aircraft continued to fly anti-submarine patrols over the Mediterranean, sinking on 4 March 1943. On the night of 23/24 April, a Hudson was badly damaged while attacking , the pilot being killed. The aircraft was flown back to base by its radio operator, where the surviving crew bailed out. In late September 1943, and working closely with the Special Operations Executive (SOE), who were also stationed at La Senia developing underwing rockets and radar for the Hudsons, a Hudson and crew from 500 Squadron was chosen to fly into occupied Corsica at Ghisonaccia Gare aerodrome, with the orders to "establish squatters' rights" under the command of Colonel McKenzie of 458 Squadron. Later, from December 1943, the squadron's Hudsons began to be replaced with Lockheed Venturas. This process continued until the squadron was completely equipped with them in April 1944. The squadron operated from a range of bases over the Western Mediterranean, including bases on Sicily, mainland Italy and Corsica. On 17 May 1944, the German submarine launched an unsuccessful torpedo attack against the American destroyer off Mers-el-Kébir, which resulted in a large-scale air and sea operation to hunt the submarine, involving five American destroyers and saturation air cover from the Wellingtons
