Working from top to bottom - 1 Sqn were based up north at Bailluel thru 1916, 1917 and into 1918 only leaving this loc during the Battle of Lys in Apr 18. I think we can safely say their loss was due to Flak.
As to the FE / Vickers claims. I must admit that I do not own NF's Jasta Boelcke
(broused thru it once) so the 2Lt Roberts post capture report and indeed the first hand words of Kirmaier are new to me. And on the basis of those, your argument that Leffers downed 6965 would seem sound.
HOWEVER - there is a time frame problem. As we know from the Werner book Boelcke claims that in company with Ltn Bohme he attacked a formation of 6 'Vickers
' and that he was joined by three of Jasta 1 and that he observed '...Leffers, of Jagdstaffel 1, tackled one first and forced him down
..' drive down one of the Vickers. And indeed the Leffers claim time is 1200GT. Where as the Boelcke claim is at 1210GT. Now I find it interesting that Boelcke's own account has many points of contact with the Roberts EOW account in that he says 'I picked out the lowest of them, attacked him and forced him away from the others, so I had him to myself
..' going on to relate a second attack and sent him down to crash burning 500m west of Bullecourt.
Now I always feel it is important to have visibility of the story from the other side, and not as has been the predelection of so many pro-German enthusiasts; to dwell overly on the much sparser German visibilty in conjunction with the British loss data only
, as this approach often only provides half the story.
What I do know is that the 5 strong 11 Sqn photo mission was engaged over Queant (16km German side) by as many as 20 EA! And that 6965 was seen chased down (but not crashed) over Queant. The fighting then continued back to at least Mory (10km German side) where crew of Capt Price & Lt Libby sent one of the attackers down apparently OOC at 1115BT (1215GT). And of course the Roberts account says hit in the motor he made it back to no-mans-land at Le Sars (this had been captured by Brit 23 Div on 7 Oct 16 - incidently the very fighting in which Adolf Hitler was wounded). Now I get the feeling Boelcke did in fact drive down and chased 6965 back to Le Sars, but somehow he was credited with the FE which crashed crashed 500m west of Bullecourt - Queant being just east
of Bullecourt. And that this FE was in fact 7670 and moreover very likely the one downed by Leffers at the beginning of the fighting.
How can this be? You likely ask. We'll I for one do not believe the German claiming system was as squeaky clean as many have been want to claim. It may well be that on return, Js 2 rang around for word of a downed Vickers
- but only recieved word of one down near Bullecout - and that was 7670! News of of the other downed Vickers (6965) may not have been so forth coming, being as it came down right on the front line and in an ongoing battle! I'm sure the German front line commanders had more to worry about than pesky phone calls from the pampered flyboys. And as an OPleM holder and Germany's leading ace, I suspect that Boelcke may have got preference over Leffers in relation to credit for the FE down at Bullecourt. And that his CR was written up to reflect this (location wise) Ultimately I would suspect that news of a second downed Vickers(6956) to SW of Bapaume filtered through and Leffers duly got the credit for that one as his victory #8.
As to the Kirmaier claim and the 23 Sqn loss, this would seem to be the case, but one has to suspect Kirmaier was refering to a crash near his old
aerodrome Bertincourt and not Lagnicourt. Similarly British 'visibility' will show 23 Sqn were on a recon and not a bombing mission as the German visibility implies.
As to the Js 5 Theiller claim - If one looks at relevant battle maps then one will see N of Maurepas would be well inside Allied lines (French Sixth Army sector of Somme) and as you will find as we proceed, these jenseits
claims can be every bit as falible as the many British claims over German lines, when it comes to finding the so called 'hard kill'. JWC does give 18 Sqn, but I do not know on what grounds. Maybe Graeme can shed some light. Again I would strongly suggest there are no hidden British losses. Maybe a French aircraft? But I think the bottom line is that the German claiming system was no where near as accurate as the conviction long held by so many.
St Nazaire Raid - one of the most gallant raids of all time.
