The importance of this report is twofold: firstly it covers the strategic/operational bombing effort in the important period before and during operations to recapture France and the Low Countries and secondly it classifies attacks by target type. Thus the targets covered include ball and other bearings, oil, submarine yards, tanks, armaments and transportation. It also includes both the USAAAF and RAF efforts. Attacks are dated, and the data includes place, importance, and damage done.Although obviously based to an extent on crew reports, all targets were photographed before, during and after the attack so it appears that the damage assessments are not too wide of the mark.
