Interesting, but not 4./KG 40 logbooks I have been looking for.
Yes, these losses for III/KG 40 are all known
:
F8+ES was probably the He 111 H-5 F8+ES W.Nr. 4070 missing 19.08.41 (Nordsee) w. other crew of four - but they returned five days later.
F8+BS was probably the He 111 H-5 F8+BS W.Nr. 4081 missing 24.08.41 ("Ostküste England")
with Pilot "Gefr. Gerhard Dohmen" + 3 crew. One of these was reported killed 03.10.41, Dohmen and other remain missing AFAIK
I will look up the actual GQM record and check on spelling of them. Stand by ... but yes, his name is spelled that way in GQM loss listings.
