One of the many Ballentine Series on the Illustrated History of WWII, this is Battle Book No. 30, describing the allied bombing raid on the Roumanian oil center of Ploesti. Heavily illustrated with many period photos.
A very readable and even-handed account of the raid on the Rumanian oil refinery complex. A diagram of the various installations and their location with respect to the town of Ploesti would have been useful.
