Suggestions are O.K. for me! You were well-advised to call suggestions suggestions now. – So hopefully I can take you a bit more serious now.
I think we can agree that tangible proof for the destruction of four German airplanes in this battle can not be provided until now.
At least the two major problems are preventing to turn the suggestions - made by RG - into more than only suggestions:
1) In general a reasonable matching of victories and losses requires fitting locations, times and circumstances (if available). It is no correct science but should be done in a scientific manner.
2) Researchers are often very ignorant to the “world outside”! They look at the claims of “their heroe” or research subject and forget about the fact that other pilots did score on this day too. Therefore it is necessary to compare the claims of all other pilots with the enemy losses as well!
RG´s suggestions are:
1) Ltn Wattenberg (KIA, FAA 207) location: Pont Avache time: ?
2) Vfw Schymik (KIA, Jasta 24s) location: N Pormereuil time: ? (not reported in KTB J24)
3) Ltn Hinky ((WIA, shot in the leg, Jasta 44s) location: ? time: ?
1) Without time of the loss or a very well-fitting description of the incident is no real matching possible. Ltn Wattenberg could have been killed by any other British aviator (or AAA?) as well.
2) RG has the suspicion the loss of Schymik– and Altemeier´s victory- happened one day earlier. So-called “late entries” (delayed entries) of victories and losses happened on both sides and have to be taken in account.
My copies of the Jasta 24s material display no (!) time for Schymik´s loss. It is not possible to say if this loss happened in the same mission like Altemeiers victory (R.E.8 reported for 28.10., KTB J24: 9.25 hours vs
ATL: 9.20 hours, near Happegarbes). As well additional information is necessary to prove the assumption that this incidents happened one day earlier.
3) Without time of the loss or a very well-fitting description of the incident is no real matching possible. Ltn Hinky could have been wounded by any other British aviator (or AAA?) as well. (Hinky, a newcomer, came 16 days ago from Jastasch II.)
Based on the afore mentioned I would conclude it is too early to make hastily statements like
a) the victims of Barkers last combat are known or proven OR
b) Barker was not successful at all in his last combat.
By the way: I am pretty convinced Barker was in a great fight – however, I really wonder about the missing reports of “thousands of observers”! It seems to me the problem with the “case Barker” is not only a problem of lacking German documents. At least I would like to see more reports of the thousands of eye witnesses [sic] of the fight.
