When the Spitfire Mk I First Met the Bf 109E: Ten Minutes That Changed the War
Before May 23, 1940, no Spitfire had ever confirmed a kill against a Bf 109. Two Spitfire Mk Is vs twelve Bf 109Es over Calais-Marck. Alan Deere's combat report rewrote RAF fighter doctrine. This episode covers: The untested rivalry — Spitfire Mk I vs Bf 109E. Why RAF intelligence believed the Messerschmitt was unbeatable based on the Hurricane's combat losses over France, and why that conclusion was built on the wrong comparison. The Calais-Marck rescue — Flight Lieutenant James Leathart's unarmed Miles Master trainer crossing the Channel to recover Squadron Leader Laurie White of No. 74 Squadron, escorted by Pilot Officers Alan Deere and Johnny Allen of No. 54 Squadron RAF, Hornchurch. Rolls-Royce Merlin III vs Daimler-Benz DB 601A — carburettor float-feed vs fuel injection, turn rate vs dive speed, negative G performance. The engineering gap that shaped every Spitfire-vs-109 engagement through the Battle of Britain. Alan Deere's post-combat assessment — the first Spitfire pilot to compare the two fighters from direct combat experience, and why his report mattered more than his kills. The "Nine Lives" aftermath — Deere's extraordinary survival record through the Battle of Britain: mid-air collisions, forced landings, low-altitude bailouts, and a bomb blast at Hornchurch.
