Here is small episode from the combat efforts of Lilya Litvyak. On 22 March 1943, Litvyak was attacked by four Messerschmitt Bf 109s over Khar'kov area. Litvyak managed to shoot down two of the German fighters, while driving off the rest. This aerial engagement coincided exactly with the only two German Bf 109s lost in the same area on this date. The two German fighter pilots shot down were Leutnant Franz Müller (Bf 109G-4, coded "BH + XB") and Unteroffizier Karl-Otto Harloff (Bf 109G-2, coded "yellow 2") of the 9th squadron, fighter wing 3 (9./JG 3). German records have each of these men, who both survived, being reported shot down by Russian fighters. Lilya Litvyak was killed on 1 August 1943.
Incredible story of achievment.
