Hey Bill I just got a book from Hendon and it details Blenheim operations
Barry Davidsons account of July 6th, 1940
"I was with 18 squadron at West Raynham from July 4th to July 6th! My crew were SGT Gilmour and SGT Fisk - we were shot down after after bombing a new airfield. We had one 500lb bomb and two 250lbs. I had the C.O's plane.
We were hit after bombing at 1,800 feet, all the controls were out and we rolled over and dived, I reached the tail trimmed and it brought us out of the dive. We got to the coast and flew NW to England. Compass was gyrating, we were low and the cliffs came up on my left, which we thought was English - turned out we had made a circle and it was between Calais and Dunkirk - crash landed, still thinking in England, when the goons arrived on the scene. My flying time on Blenheims, including this trip, was just over 4 1/2 hours, great!
Spent the next five years as a PoW, mostly in Stalag-Luft III. At least we survived, which very few Blenheim Crews did."
