THX for great answer, Chris! Now I see, I./ZG 1 and II./ZG 1 were not at the same combat. I./ZG 1 intercepted Americans, and II./ZG 1 - British in other place.

Was the target of Bostons Brest-Sud. airfield, base of II./ZG 1? Gruppe losses on ground:

Bf 110 G-2, 150112, 100%, Destroyed in bombing attack.
Bf 110 G-2, 5628, 50%, Damaged in bombing attack
Bf 110 G-2, 6175, 10%, Damaged in bombing attack.

During combat with 66 Sqn., from 14:45 to 16:25 I found 3 claims:

Ofw. Berger, 6./ZG 1, Mitchell, 5965: 2.300 m., 15.45 (B-25"Mitchell" or A-20 "Boston"?)
Fw. Franz Meissl, 6./ZG 1, Spitfire, 5968: 2.000-700 m., 15.45 (total 11 victories, incl. 2 Viermots+2 Spits)
Uffz. Anders, 6./ZG 1, P-47, 5966: 1.200 m., 15.47 (P-47? May be misidentification? Both P-47 and Spit have elliptic wing)

Are british losses known?
