Friendly fire WWII

[Laurent Rizzotti]

Hello, just read the following in the book "The Pendulum and the Scythe", the history of 4 Group RAF by Ken Marshall, 1996:

"By mid-1941, Germany possessed 250 twin-engined night-fighters (Bf110, Ju88 and Do217) backed by an increasingly effective ground control and reporting organisation. From the middle of 1941 the above system gradually became integrated with the Luftwaffe's Flak arm to create a 'Combined Nightfighting' (Kombinierte Nachtjagd) system around the cities of Bremen, Cologne, Darmstadt/Mannheim, Duisburg, Frankfurt, Hamburg, Kiel and Munich. Flak was normally limited to a height of 4,000 metres, although this could be raised at the discretion of the Division Kommandeur. For various reasons this resulted in quite a few night-fighters being shot down by their own Flak and, not sirprisingly, this system was abandoned by the end of the year."

My understanding of the above is the system was set in place in mid-1941 and was abandoned before the end of 1941 after "quite a few" German nightfighters were shot down.

Problem: I have checked both books of Michael Balss on Nachtjagd losses and I can't find any German nightfighter shot down by friendly Flak over Germany in this period. I found one in Germany in February 1941 and one over Holland in July.

Here are all the case I found for 1941:
