During the winter of 1942-43, the air battle raging in the skies over Europe was at its fiercest. The Focke Wulfs and Messerschmitts flown by the Luftwaffe’s ’experten’ proved to be more than a worthy foe for the RAF’s new Spitfire Mk.IX-s. The air supremacy of the Allies was still just a distant dream. In the thickest of this battle stood the Biggin Hill Wing with 611 (West Lancashire) and 340 (Ile de France) Squadrons.
