9 April 1940: S/L George Peacock, No. 9 Squadron

[SteveR]

I'll try to keep this short...

In Shores' Fledgling Eagles it is stated that on 9 April 1940 a Wellington on No. 9 Squadron, returning from an operation to Norway, shot down a Do-18 of 3/406, the crew of which perished, without giving any details of the combat.

In Gordon Thorburn's Bomber Command 1939-1940 the author states that the victorious Wellington was that of S/L George Peacock and that Peacock was awarded the D.F.C. for it.

There's nothing about it in Thorburn's Bombers First and Last or in Mason's 9 Squadron.

I went to the National Archives website to try to find more info. Searching the Air 50 files for a combat report yielded nothing. Searching Air 27 I found confirmation of the D.F.C award but nothing about the combat - not in the ORB or any of the 500+ pages of Appendices.

Questions:

Have I missed something in the NA? Can anyone suggest search terms that might help me find something there? Does a combat report for this encounter exist?

Does anyone have any more details of this combat from the RAF perspective (the commander of the Do-18 is given in Shores; since the crew perished I figure there's not much to be had from the Luftwaffe perspective)?

Thanks in advance for any help!
