RAF 156 Sqdn Lancaster Crash Site

[Wayne Welford]

Hi There,
I am looking for some help on behalf of my grandfather.

His bestmate Gerald Peter Robert Bond,DFC.(Better known to his mates as Peter Bond) was a Lancaster pilot with 101 Sqdn and later with 156 Pathfinder Sqdn.
I have information on the crew and crash date of this aircraft it is as follows, Lancaster III ND384 GT-D shot down on the return journey from a successful raid on Berlin on the night of 1/2 Jan 1944.

The information that I am looking for is that British records show this aircraft crashed at Grandreu,Belgium. But other information I have received from Luftwaffe reports says this Lancaster was shot down at
Estines au Val Belgium.
I would dearly love to know which is correct and if anyone can help, my grandfather and I would greatly appreciate it.

Also if anyone may have a photograph of P/O Bond or crew/aircraft could you also please let me know.

Thankyou very much for your time.
Wayne
