Can you kill first cuman in Skalitz with bow? (Yes, you can)

As wished, i made a video about killing first cuman with bow. Had a bow skill at level 0 so it obviously sucked. Took me some tries, it was harder than expected. He seemed to bounce off several arrows and also glitched heavily. Other cumans also appeared quite soon, except for the last try when they didnt appear at all which was strange... I guess the headshot is plausible, but luck-based.
