By October the "Luftwaffe" had reinforced "Fliegerkorps II", and a new round of heavy raids began, using new low-level tactics. However, these attacks also lost heavily to the AA guns and RAF fighters, despite the increasing shortages of food and supplies on the island. At last, in November "Welshman" and her sister ship HMS "Manxman" appeared, followed by a supply convoy. With the Axis defeat at Alamein and the Allied North Africa landings (Operation Torch) the same month, the siege of Malta was ended. The only enemy air activity for the rest of the year was occasional high-flying reconnaissances and one raid on Luqa in December.
