So, his total is 352, as awarded in WWII, until we CAN prove it. That's the way it works. Prove it or accept history as-written.
After reading your posts I'm really not clear what you
would accept as proof. Let's look at a really straightforward, localised action and you can let us know which of the following you would accept and which you would not.
80 years ago last Sunday, the US 8th Air Force flew Operation Cadillac, a major supply drop to French resistance fighters on the Vercors plateau. The Bf 109s of
Jagdgruppe 200 intercepted the B-17s and their escort close to the target area. No other German fighter units were based in southern France at the time (Primary source:
Jagdfliegerführer Südfrankreich unit strength and disposition returns deciphered by the British), no other Allied forces were operating over the Grenoble-Valence-Vercors area that morning (primary source: Medirerranean Allied Tactical Air Forces Daily Intelligence/Operations Summary).
German primary sources in the Bundesarchiv accredit four claims by pilots of 2./JGr. 200:
Lt. Heinz Moschke Stirling 09.17 Romans-sur-Isère
Ofw. Eduard Isken B-17 09.17 Valence
Ofw. Tchrer B-17 09.18 Valence (shot out of formation)
Ofw. Läbe B-17 09.25 Valence (shot out of formation)
British primary sources in the National Archives (deciphered German signals) include a mission report showing that 21 Bf 109s operated and had initially claimed a Fortress shot down, two shot out of formation and one damaged plus a Stirling probable and a Mustang probable.
(This was an American daylight operation in which no Stirlings took part, so it seems that a B-17 was wrongly identified by Moschke).
An American primary source, the 8th AF Mission Report, records no B-17s shot down. The 94th Bomb Group was the only one to report any damge. It had eight aircraft category A (repairable within 36 hours) and category AC (repairable in over 36 hours). Some were attributed to Flak or other causes while four were by "fighter alone" and two by "fighter and other." Two of the bombers involved in Cadillac landed on strips in the Normandy beach head with their crews safe.
Turning to another German primary source, a pilot's
Flugbuch, the Mustang "probable" may have been that claimed by Uffz. Ohmert in the area Valence–Grenoble–Lyon: he noted it as "Accredited (eyewitnesses). 1 point" but there is no surviving victory credit. The 357th FG did however record one of its aircraft as damaged "Cat. AC."
American fighter escorts claimed four Bf 109s and one Fw 190, bomber gunners claimed 5-2-2 (primary source: 8th AF Mission Report). German losses were: six Bf 109s total loss; two pilots dead, one missing and three injured (primary source: deciphered JGr. 200 report).
My reading of all that is NOBODY on either side made accurate claims. The Germans even accredited two four-engined bombers shot down over their territory for which they could not possibly have found corresponding wrecks because the USAAF lost none.
