side of his aircraft's fuselage at about a 30° horizontal angle. On 25 July 1915 Captain Hawker flew his Scout C, bearing RFC serial number 1611 against several two-seat German observation aircraft of the Fliegertruppe, and managed to defeat three of them in aerial engagements to earn the first Victoria Cross awarded to a British fighter pilot, while engaged against enemy fixed-wing aircraft. 1915: The Fokker Scourge The first purpose-designed fighter aircraft included the British Vickers F.B.5, and machine guns were also fitted to several French types, such as the Morane-Saulnier L and N. Initially the German Air Service lagged behind the Allies in this respect, but this was soon to change dramatically. In July 1915 the Fokker E.I, the first aircraft to enter service with a "synchronisation gear" which enabled a machine gun to fire through the arc of the propeller without striking its blades, became operational. This gave an important advantage over other contemporary fighter aircraft. This aircraft and its immediate successors, collectively known as the Eindecker (German for "monoplane") – for the first time supplied an effective equivalent to Allied fighters. Two German military aviators, Leutnants Otto Parschau and Kurt Wintgens, worked for the Fokker firm during the spring of 1915, demonstrating the revolutionary feature of the forward-firing synchronised machine gun to the embryonic force of Fliegertruppe pilots of the German Empire. The first successful engagement involving a synchronised-gun-armed aircraft occurred on the afternoon of July 1, 1915, to the east of Lunéville, France when Leutnant Kurt Wintgens, one of the pilots selected by Fokker to demonstrate the small series of five special Eindecker service-test prototype aircraft, forced down a French Morane-Saulnier "Parasol" two seat observation monoplane behind Allied lines with his Fokker M.5K/MG Eindecker production prototype/service-test aircraft, carrying the IdFlieg military serial number "E.5/15". Some 200 shots from the synchronised Parabellum MG14 machine gun on Wintgens' aircraft had hit the Gnome Lambda rotary engine of the Morane Parasol, forcing it to land safely in Allied territory. By late 1915 the Germans had achieved air superiority, rendering Allied access to the vital intelligence derived from continual aerial reconnaissance more dangerous to acquire. In particular the defencelessness of Allied reconnaissance types was exposed. The first German "ace" pilots, notably Max Immelmann, had begun their careers. The number of actual Allied casualties involved was for various reasons very small compared with the intensive air fighting of 1917–18. The deployment
