A page from "The Night Hamburg Died", Martin Caidin, Four Square/New English Library, London, 1966. Originally published in USA by Ballatine Books, Inc, 1960

The text between the pictures reads:

The Borstelmannsweg section in Hamburg, part of the firestorm area. Temperatures here reached to 1,472 degrees F. (Below) Despite the shattered and fire-gutted appearance, this district, near the waterfront was not part of the firestorm. This section was hit on the first heavy raid, and large mass fires exploded outward. The streets have already been cleared. National Fire Protection Association

(Note that Caidin has worked for US "intelligence":

In Japan for two years with the Intelligence and Public Information offices of the U.S. 5th Air Force, Mr. Caidin toured the devastated Japanese cities, and spent much time in Hiroshima, where the world's first atomic bomb used in the war was dropped.
