Nevil - results of a quick Google search: 7th Sept. 1940 : Germany starts it's Blitz on London with 300 German bombers in the first of 57 consecutive nights of bombing. The Blitz caused the deaths of over 40,000 men women and children and left a million homes destroyed in the city. wikipedia.org After 5th July the Intelligence Staff issued no further invasion alert until 7th September when all home defences were brought to a state of “immediate action”. From Bletchleypark.org.uk. Thanks for the very interesting quotes, Mike. After I had posted my write-up I remembered the name of the German invasion plan, Sea Lion, and looked it up. However, the info I read did not mention September 7 so I was gratified that from your quote above, my memory had not been inaccurate in that respect. I also recalled that for quite a while after September 7 there were rumours about hundreds of bodies from a German invasion force floating in from the Channel It was interesting also to see the quotes from Bletchley Park. I don't know if I have mentioned it previously but I served there for a comparatively short time, a few months. Of course, as a DR I knew it was a top secret cipher (cypher in Brit-speak?) training unit but we really did not know the full extent of what was being done there. Anyway, I recently got a fancy badge and a certificate of thanks from your current PM.......better late than never I guess but I did not really earn anything, just doing the usual DR stuff, mainly from Bletchley to the War Office and a few other places in London. Of course they would not use wireless/radio from there and even telephone was not trusted so it had to be DRs. Nevil.
