Hawker Hurricane Mk Is on 20 February 1941. That day, Pattle, flying Hurricane Mk I V7724, was leading a group of six Hurricanes escorting 16 Blenheim light bombers — eight from No. 84 Squadron RAF, six from No. 211 Squadron and three from No. 30 Squadron RAF—to Berat. Fiat G.50bis from the 361a and 395a Squadriglia, 154° Autonomo Gruppo were scrambled from Berat airfield, but they were attacked by the higher altitude Hurricanes. Pattle led his section straight towards four Fiat G.50s and selected the leading aircraft as his own target. It was the first time he had fired the eight guns of the Hurricane, and the G.50 exploded. The Fiat G.50 was from 154° Gruppo and it was the first Hurricane victory that Pattle claimed. Tenente Livio Bassi was killed in this battle. Another CR.42 fell to Pattle on 27 February 1941 — his 17th victory. His Hurricane sustained a bullet hole in the fuel tank. On 28 February, British pilots in Greece celebrated their biggest success in combat. No. 80 Squadron claimed 27 Italian aircraft without loss in 90 minutes of air combat. Pattle himself claimed three Fiat CR.42s shot down in less than three minutes. The Regia Aeronautica claimed that day it lost just one CR.42 (as confirmed by Italian pilot Corrado Ricci, a participant in those battles), plus four Fiat BR.20s and two G.50bis. The Italians claimed six Gladiators and one Supermarine Spitfire — none would be in the Mediterranean Theatre until March 1942 — while in fact only one Gladiator of No. 112 Squadron was lost, while two Blenheims, attacked by CR.42s had to crash-land returning to base. In a previous fight south of Vlorë, Pattle had to return to base with the windscreen covered by oil from a shot down enemy bomber. His tally was now 21 air victories. Later sources suggested two of Pattle's claim were from the 37° Stormo. On 4 March 1941, Pattle claimed three enemy Fiat G.50bis fighters (nos 22–24) belonging to 24oGruppo. He claimed the first, while Nigel Cullen — another leading fighter ace — flew as his wingman. Escorting Blenheims to attack Italian warships, the pair were engaged by a lone G.50. Pattle engaged the Fiat and shot it down — its landing gear dropped down and it rolled over and into a mountainside just north of Himare. Pattle searched for Cullen, expecting him to be behind him
