Hi Stephen and welcome to the forum.
I have consulted a reference book on my shelf called RAF Bomber Command Losses of the Second World War 1944 by W R Chorley. It lists all Bomber Command losses of a/c flying from UK bases in 1944.
This is what is says about the loss of the a/c your uncle was onboard. Please note the a/c serial number differs from the one you quoted. Hopefully someone should be able to confirm which is correct.
Halifax III MZ925 C8-F on op to Sterkrade, took off 1429 Leaconfield. All onboard killed. Five of the crew are buried in the Reichswald Forest War Cemetery, while panel 228 of the Runnymede Memorial perpetuates the memory of Sgt Davies and Sgt Dryburgh.
F/L P Hetherwick +
Sgt R M Davis +
F/O J G MacPhee RCAF +
F/O J A G Julien RCAF +
Sgt W R Dryburgh +
Sgt L Kilvington +
F/Sgt A S Nairn +
End of info from Chorley.
You can look up each of the airmen listed above on the Commonwealth War Graves Commission website to try and obtain further info such as first names, service numbers, grave number, possibly where they came from http://www.cwgc.org/debt_of_honour.asp?menuid=14
Hope some of the above is helpful for you.
As an aside, I've typed the serial number and code letters exactly as per Chorley but I've never seen numbers used in the code letters before. Would anyone care to enlighten me?
Regards
Linzee
