Quax, thank you for making us aware of Donald K. McClure's very interesting memoirs. Are you perhaps Mr. Arzberger mentioned in the story?
On the date that you are interested in, there were two large raids by the American Fifteenth Air Force on the Steyr ball-bearing factory and the Steyr-Puch aircraft factory. The Luftwaffe response to these raids is sumamrised in Donald Caldwell's excellent volume,
Day Fighters in Defence of the Reich: A War Diary, 1942–45. I have extracted the following information from the book: two Bf 110 units participated in the attack on the American bomber stream. III./ZG 76 flew 28 sorties from Öttingen in Bavaria and II./ZG 1 another 32 from Wels in Austria. III./ZG 76 claimed one B-17 shot down for the loss of four aircraft and two crew members killed. II./ZG 1 claimed three B-17 and three B-24 bombers. It lost five aircraft, with five men killed, two missing and two wounded.
The book can be bought on the publisher's website, in both
hardback and
electronic versions. Donald is a great researcher and the book is
thoroughly recommended.
You will see in Matti's great set of data above that information about aircraft losses involving aircrew casualties is usually available. This is because personnel casualty reports included data about the aircraft involved. In cases where there were no aircrew casualties, data for 1944 is often unavailable, because the original Luftwaffe loss records for that year have been lost.
