Future 48 victory ace, Pour le Mérite (Blue Max) holder and Staffelführer of Jasta 10, the great Leutnant Werner Voss, in front of his Albatros D.III, 1917. Arguably the best fighter pilot of the war, he was a close friend of Manfred von Richthofen and in MvR's own words, the only pilot who could have surpassed him victory wise. At the time of Voss' death, MvR had shot down 61 planes vs Voss' 48.
However, Voss didn't fly during Bloody April, when the Luftstreitkräfte (Imperial German Air Service) absolutely shredded the Royal Flying Corp, the English losing 245 aircraft to Germany's 66. MvR shot down 13 planes during Bloody April, so it's fair to assume Voss would have scored a similar tally, which would have made them level pegging on the score chart. Voss scored his first victory on 26 November 1916, and his last on the morning of his death, 23 September 1917. 48 victories in just 10 months.
He was KIA in the greatest dogfight of the war around 1830 hours. He was leading a patrol in his new triplane prototype Fokker F.I. He outdistanced his five fellow pilots who were flying slower Pfalz D.IIIs. Thus having no support, he found himself fighting at least 10 RFC aircraft. Forcing 4 off through damage he began his final battle with the remaining 6 aircraft. He put holes in every one of them before finally succumbing after 8 minutes of sensational flying.
As he had several opportunities to escape but chose to stay & fight, it has been speculated that he wanted to close the gap between his score and that of his best friend MvR. The leading British pilot he fought that day, future 57 victory ace James McCudden VC, expressed sincere regret at Voss' death: "His flying was wonderful, his courage magnificent and in my opinion he was the bravest German airman whom it has been my privilege to see fight"
