"before Hitler's war"

Hitler's war is, of course, World War 2 (1939 - 1945).

'The Blitz', the sustained aerial bombing of Britain by Nazi Germany, occurred between September 1940 and May 1941. At its worst, London was bombed for seventy six consecutive nights. To see a digitised image of St Paul's during fires unleashed by Blitzkreig bombing visit this page.
