I've heard about the German ace with the highest reported kills Erich Hartmann but in reading his engagements with the US Arrmy Air Force I wondering how he was able to down so many P-51s. I'm assuming the P-51 was a superior fighter to his Messerschmitt Bf 109, so was it mainly a matter of the inexperience at the time of the US P-51 pilots he was facing as reported in the wikipedia quote below?

On 21 May 1944, Hartmann engaged United States Army Air Force aircraft in Reichsverteidigung for the first time. While flying "top cover" for another Schwarm, Hartmann attacked a flight of four P-51s over Bucharest, Romania, downing two, while the other two P-51s fell victim to his fellow pilots. On 1 June 1944, Hartmann shot down four P-51s in a single mission over the Ploieşti oil fields. Later that month, during his fifth combat with American pilots, he shot down two more P-51s before being forced to bail out, when eight other P-51s ran his Messerschmitt out of fuel. During the intense maneuvering, Hartmann managed to line up one of the P-51s at close range, but heard only a "clank" when he fired, as he had run out of ammunition. Whilst hanging in his parachute, the P-51s circled above him, and Hartmann wondered if they would take this opportunity to kill him. One of the P-51Bs flown by Lt. Robert J. Goebel of the 308th Squadron, 31st Fighter Group, broke away and headed straight for him. Goebel was making a camera pass to record the bailout and banked away from him only at the last moment, waving at Hartmann as he went by.
