as Roadstead but without bombers) along with Rhubarb and Circus operations. On 5 February, Finucane participated in the third Circus operation. 65 supported 610 and 302 Squadron over Saint-Omer. Leading high cover, Finucane claimed another Bf 109 over Cap d'Alprech as three German fighters attempted to attack the other squadrons from behind. It was seen to crash into woodland. On 26 February 1941, 65 Squadron was posted to Kirton in Lindsey. The airfield was located in Lincolnshire in No. 12 Group RAF's sector where air-to-air combat was very uncommon in daylight. The stay at Lindsey was short. On 14 April 1941, Finucane was posted as a Flight Commander to the newly formed Australian No. 452 Squadron RAAF, the first RAAF squadron to serve in Fighter Command. He was promoted to acting flight lieutenant the same day. The following day, 15 April, he flew his final sortie with 65 Squadron flying support for 266 Squadron and 402 Squadron. On the way back in the afternoon he claimed one Bf 109 destroyed. This, his fifth victory, made him an official fighter ace. However, according to other accounts, only two Bf 109s were involved in the brief air battle. Finucane's and 65's likely opponents in the battle was Adolf Galland, Geschwaderkommodore (wing commander) Jagdgeschwader 26 and future General der Jagdflieger (General of Fighter Forces). Galland had taken off with his wingman and a crate containing lobster loaded into the fuselage of his Bf 109 to deliver to Jagdfliegerführer 2 Theo Osterkamp for his birthday at Luftflotte 2 headquarters. En route, Galland took a detour over the English coast and attacked several flights of Spitfires, claiming two 266 squadrons shot down. Galland's landing-gear fell down during the battle, possibly leading Finucane to claim it as destroyed. Both German pilots returned to France, their machines undamaged. Finucane was awarded the Distinguished Flying Cross (DFC) on 25 April. Finucane's start at No. 452 was unimpressive. On 3 May 1941 while on a recognition flight with his new commanding officer, Squadron Leader Roy Dutton, Finucane got too close and his propeller sliced through Dutton's tailplane. Finucane radioed Dutton immediately. Dutton attempted to abandon the aircraft but was too low and crash-landed, cracking several ribs but surviving. Finucane excused himself from error asserting that his Spitfire was the only one with a metal propeller—the others being elder Mark I's with wooden mounts—which gave him extra speed. In tight
