Sorry to hear about your loss ... you may already have this but the 166 order of battle for the night is available on: http://www.aircrewremembered.com/raf1944/4/singletonbernard.html along with a sentence on the loss (talking about No 1 Squadron SAS helping out with their escape).
He was my uncle and sadly past away on Sunday, (91) and I am giving his eulogy next week.
He was a mid-gunner in a Lancaster of 166 squadron and during a mission to Stuttgart on the 25th/26th July 1944 when the plane was posted missing. The crew all bailed out over France and apparently all survived. The planes call sign was Zebra.
Hugh hide in a barn for a few days until the farmers daughter helped him with his wounds. i believe he was looked after by the French until the allied forces pushed the Germans out.
He would never talk too much about the experience and I am wondering there're is any information available? Such as where the plane came down.
