Agreed, trumper, I’ve never seen it before. I believe that the German casualties of the day, at least those who died locally, are still in Saffron Walden Cemetery rather than at Cannock Chase, while Edwards is buried, I think, at Brookwood.
I was hoping to find the account of the raid in one of Hector Bolitho’s books, but it seems to be in Essex. I guess it’d still be in copyright as well, so perhaps a good thing?
