The aircraft crashed near Kempen, according to info from BC Losses, and only one of the crew survived, F/O J.B. Auld, RCAF. I have a copy of the 166sqdn Operations Record Book, and if you would like information on any previous operations carried out by this crew, can you let me have your email address via my whiteboard in my profile.
From the details i've found in the ORB, it would appear that Leslie was unfortunatley, not due to fly that night, as the crew he was lost with, was not his normal crew. It looks as though he stood in for the the W/Operator of Teasdales crew for reasons not known, but possibly through sickness. Leslie's own crew were not scheduled to fly that night.
He was posted in during January 44,
F/O W. Hutchinson, Pilot.
Sgt F. Reed, F/Eng.
F/Sgt H.R. Eaton, RCAF, B/Aimer.
F/O A.V. Clifford, Nav.
Sgt L. Gammage, W/Op.
