power station escorting six 2 Group Blenheims. JG 2 and JG 26—the only Luftwaffe wings in the west—reacted. A series of dogfights started at 18,000 ft and ended near 4,000 ft. Finucane claimed one destroyed and one probable. One fell near Gosnay the other was left pouring black smoke at only 500 ft in the Calais area. Truscott claimed a third but 452 lost two pilots—Bill Eccleton and Dick Gazzard. The squadron attracted attention through its successes and Sholto Douglas visited them on 21 August. The following day Finucane was awarded a Bar to the DFC. The citation read, "Flight Lieutenant Finucane has been largely responsible for the fighting spirit of the unit." Circus 85 on 27 August 1941 was meant as an escort mission but the Blenheims of No. 139 Squadron RAF arrived at the rendezvous 30 minutes early and veered off to England. Four wings crossed the coast at 07:12 at 18,000 ft. The Germans reacted and there followed a large air battle which the squadron claimed four Bf 109s—two by Finucane. 452 Squadron were now the most successful in Fighter Command in August. Finucane took leave in early September and his award for a second Bar was gazetted on 9 September. Circus 100B was flown on 20 September 1941. A three-pronged attack was planned involving 23 squadrons and 270 Spitfires with bomber units acting as decoys. The Kenley wing was to provide escort for bombers hitting marshalling yards at Abbeville. 452 was one of three squadrons flying high cover. Immediately after crossing the coast at Saint-Valery-sur-Somme they were engaged by enemy aircraft. Finucane hit a Bf 109 which exploded forcing him to fly through the debris but within minutes 452 had lost three Spitfires. Finding himself and his wingman, Sergeant Chisholm alone he shot down a Bf 109 that attempted to attack his squadron-mate. He followed it briefly and it caught fire while emitting white smoke. Another Bf 109 turned in to attack Finucane but was shot down by Chisholm. Fighting their way back to the Channel Finucane dived and shot down a Bf 109 which went into a spin before he lost sight of it at approximately 500 ft. Three successes had inflated Finucane's tally to 17. In command The success of 452 and its highest scoring pilot Brendan Finucane brought fame and publicity and information about the squadron's exploits was released by the Air Ministry
