............................................Oh and Munchh, the pillboxes in this report faced as follows:
PB1 facing south west down into the valley and the road that runs along it (although it's a good mile distant).
PB2 facing westerly with it's entrance towards Winchcombe
PB3 not a PB apparently!
PB4 facing north, again with it's entrance towards Winchcombe.
Looking at these facings on a map it would seem that they are defending some of the approaches to Winchcombe, certainly from the north and south/southwest anyway.
Well done Jim, now you're hooked!
The other thing you can do is to compare maps of the time to GE. If you know Rich then he can help you with that although there are links for old maps etc posted in the reference material section here if you want to find them yourself. Particularly useful for spotting features which were there in 1940 and now long gone. I've found answers to the 'what the hell were they defending?' question several times in this way.
If there's anything you particularly want to know, PM me if you think I can help. I'm sure the other guys on here will also be as willing to assist.
Good luck with your explorations, I look forward to seeing more from you.
