The most famous dogfights between biplane fighters on the Western Front, especially during the 1917, were conducted by the German Albatros D III and the British SE 5a. The German Albatros D III was flown by many top German Aces including the Red Baron Manfred von Richthofen and Ernst Udet. It was able to reach the top speed of 175 Km/h and was armed with two Spandau machine guns firing through the propeller disc. The rival of Albatros was the Allied fighter S.E. 5a. Although it wasnt so famous as the Sopwith Camel, it formed the backbone of the British Royal Flying Corp fighter squadrons showing great efficiency. The S.E. 5a was flown by Allied Aces such as Billy Bishop and Edward Mannock. Faster than the Albatros, it was armed with a 7.7 mm Vickers and with the characteristic 7.7 mm Lewis mounted on the upper wing
