Erich Hartmann only lost one wingman in his career, this being Günther Capito. Unfortunately, Hartmann never stated exactly when this happened just that it was in 1945, and all that we know is that he was credited with shooting down the P-39 that shot down Capito. I've seen some sources say it was in March 1945 but Hartmann wasn't credited with a P-39 in March 1945?
This is Hartmann's quote:
I called to him to turn hard opposite, so I could sandwich the Red fighters, but in his standard-rate bomber turn he got hit. I saw the whole thing and ordered him to dive and bail out immediately. To my intense relief I saw him leave the aircraft and his parachute blossom. I was happy to get this Airacobra, but I was mad at myself for not harkening to my intuition not to fly with Günther Capito.
