"I can only add that the four Spitfires on 29 August 1941 were shot down by II./ZG 76 "Haifischgruppe" (by Lt Drewes, Ofws Kornatzki and Spitzer, and Gefr. Bopp) against no other own losses than an injured radio operator (Gefr. Alfred Bunke) - a not at all uncommon result for this very successful Zerstörergruppe."
A rather bad period for 19 Sqn RAF, on the other hand.
John Foreman, in his "Fighter Command War Diaries vol 2 (Sept 40-Dec 41), says that 19 Sqn met four Bf 110s of 6./2G 76 off Holland, "clearly practicing bombing off the coast".
Tony Wood claims file has the following four claims:
29/08/1941 Ofw. Lambert Spitzer 6. ZG 76 Spitfire 33.2: 150m 10.50 - - yes C.2033/I Anerk: Nr.70
29/08/1941 Ofw. Heinz Kornacker 6. ZG 76 Spitfire 33.2: 150-200m 10.53 - - yes C.2033/I Anerk: Nr.71
29/08/1941 Gefr. Max-Ottmar Bopp 6. ZG 76 Spitfire 33.1: 600m 10.57 - - yes C.2033/I Anerk: Nr.72
29/08/1941 Ltn. Martin Drewes 6. ZG 76 Spitfire 33.2: 650m 11.00 - - yes C.2033/I Anerk: Nr.30
Gefr Bopp was very probably the gunner aboard one Bf 110 and not the pilot.
