Hi,
Here are a couple of ace encounters:
18 December 1942: Leutnant Franz Schiess (67 victories), Oberleutnant Erich Rudorffer (224 victories) or Leutnant Kurt Bühligen (112) shot down Warrant Officer Harry W. 'Chas' Charnock (9 victories) in Tunisia.
20 December 1942: Oberleutnant Erich Rudorffer (224 victories) shot down Pilot Officer R.J.H. Robertson (at least 5 victories) of No. 72 Squadron in Tunisia.
Cheers,
Andrew A.
