and Scylla, with the close escort destroyers and , left Iceland and joined the convoy late on 9 September 1942. One of her Swordfish aircraft was immediately sent up on an anti-submarine patrol. Bad weather prevented any flying for the following two days, but the weather cleared by noon on 12 September. The clearer skies revealed a Blohm & Voss BV 138 flying boat shadowing the convoy. Four Hurricanes took off to intercept it but could not find it in the clouds. Later the same day, a Swordfish on anti-submarine patrol sighted two U-boats; they had dived by the time the escorts got into position. The next day, 13 September, a Swordfish took off on patrol at 03:45 and attacked a U-boat on the surface. At 07:00, another Swordfish sighted two U-boats, which dived before an attack could be launched. Later another Blohm & Voss BV 138 was sighted and Sea Hurricanes were sent to intercept it, but it was lost in the clouds. At 09:00 two merchant ships were torpedoed and sunk; more aircraft and U-boats were located shadowing the convoy. This time the Sea Hurricanes did locate the German reconnaissance aircraft but found their .303 calibre machine guns had little effect on the armoured Blohm & Voss aircraft. At 15:00 six Junkers Ju 88 which had been circling the convoy headed in on a bombing attack. No ships were hit, and the Sea Hurricanes started to engage them. The bombing mission appears to have been a diversion to get the fighters out of position. It was followed with a torpedo attack by a mixed formation of 50 Junkers Ju 88 and Heinkel He 111. The planes flew into an intense anti-aircraft barrage which shot down five aircraft and disrupted the others, so that out of 96 torpedoes only eight found a target. One of the He 111s was also intercepted and shot down by the Sea Hurricanes. Another air attack by nine Heinkel He 115 torpedo bombers followed at 16:15. One was shot down by the convoy's anti-aircraft barrage, and the rest were sufficiently deterred so that their torpedoes, dropped at a distance, were easily evaded by the ships in the convoy. During this attack the Sea Hurricanes had again been diverted to look for a shadowing Blohm & Voss BV 138, which ultimately shot one of them down without any apparent damage to itself. At 20:40 a
