[Nokose]

12 Aug 1941
Starting this day out before Hahn's claims to clear up the losses of the 41 Sqn during this day.
41 Sqn near Hazebrouck
Spitfire Sgt A.L. Bull (POW)
Spitfire Sgt R.L. Chapman
German Claims
Maj. Walter Oesau Stab/JG 2 Hurricane 11:43 no location
Fw Günther Seeger Stab/JG 2 Spitfire 11:45 10 km NNW of Calais
Lt. Arthur Beese Stab III/JG 26 Spitfire 11:50
Seeger's location clearly puts him out of these losses.

Donald Caldwell's JG 26 puts them out of the claiming in France regarding the RAF circus missions.
Circus 69 area of St Omer 09:48-
RAF losses
54 Sqn Spitfire P/O R. Powling (WIA) damaged St. Omer
222 Sqn Spitfire P/O Christie (KIA) St. Omer

Circus 70 Gosnay 11:03-
RAF losses
485 Sqn
Spitfire Sgt Russel (POW) Gosnay
Spitfire damaged
602 Sqn
Spitfire Sgt H.J. Bell-Walker (POW)
Spitfire damaged

German claims have no locations listed
Hptm Hans Hahn Stab III/JG 2 Spitfire 12:45 and Spitfire 12:50
Uffz Ernst Federle 8/JG 2 Spitfire 12:46
Maj. Walter Oesau Stab/JG 2
Spitfire 12:50
Spitfire 12:54
Spitfire 13:06
Oblt. Erich Leie Stab/JG 2 Spitfire 12:54 and Spitfire 13:08

So for three Spitfires shot down and two damaged against eight claimed there appears to be a number of shared, especially on looking at the times and there being no locations to check against.

Circus 71 Le Trait shipyards 17:29-
RAF losses
485 Sqn Spitfire Sgt G.M Porter (KIA) Rouen, France
611 Sqn Spitfire P/O R. van der Honert (WIA) damged

German claims
Hptm Hans Hahn Stab III/JG 2 Spitfire 18:51 Ramsgate
Oblt Erich Leie Stab/JG 2 Spitfire 19:28 12 km SE of Dungeness
Maj Walter Oesau Stab/JG 2 Spitfire 19:27 15 km S of Dungeness
Obfw. Kurt Bühligen Stab II/JG 2 Hurricane 19:07 no location
I think that Bühligen is the possible victor over the 485 Sqn fighter as Hahn and the others are clearly off the coast of England.
