Mea culpa, Nick I have dipped into your research many times in the past, this was laziness on my part, and some problems with the TOCH site dropping out unexpectedly.
Two days later JGr. 200 sent up 12 aircraft to counter an allied incursion into the Montpellier area. The interlopers were probably the 20 P-47s of the Free French Gr. C. 2/5 “Lafayette” which claimed three locomotives and an He 111 but were not intercepted by the German fighters.
GCII/5 state in the Journal de Marche of the 4th Escadre that they encountered six Bf109 on that date, if not JGr.200 then who?
I will spend the morning catching up on reading "Ghostbombers"
best regards
