Hiya, I have discovered that during the Blitz from the night of October 8-9th 1940 the Luftwaffe switched from assigning bomber crews specific targets in London called 'Zielgebiet' (eg Battersea Power Station, West India Docks) to target areas of several square miles called 'Zielraum(e)' when it realised the inherent inaccuracy of their high altitude night-time bombings (Hyde et al, 1987 p.24). I am now looking to find maps of all these target areas used by the Luftwaffe, but I can't seem to locate them. Does anyone know of a possible source for these?
