Thanks Peter
The Easter raids are all too often lumped together with the November Blitz in most historical accounts (including the most recent documentary by the BBC).
The biggest difference that I can tell is that the Easter raids consisted mostly of high explosive bombs as opposed to the incendiaries used in November. That may have been because there simply weren't enough buildings left to burn? The Empire Building complex had the misfortune to be hit both times. The shops on the northern end were gutted by fire in November and the Austin Reed showroom to the south was destroyed by high explosives in April.
I'd be interested to know if the pictures on the cover are typical of the content inside?
