Excellent book by Ian Allan Publishing. The moment i saw the logo when i opened the book i thought about the Luftwaffe Colours series, if this book had some information from the apparently unavailable Nachtjager volumes. I can't confirm this, since i don't have these titles, but the first volume has a plethora of information on the strategic bombing campaign from 1939 to 1943, from the first RAF attacks during daylight, to the night bombing campaign, and the entry of the USAAF into operations.
The book is well organized, it covers with detail some of the most important actions, with diagrams, maps, and overall feels like a Luftwaffe Colours title, but with much more depth. There are accounts from the British, American, German sides, overall well balanced, together with colour profiles of some of the airplanes used in some of the operations, or shown in photos. It covers also in detail the electronic warfare, the use of radar, the development of the Himmelbet radar network, IFF, electronic counter-measures, and eletronic intelligence, the Wilde Sau and Zahme Sau tactics.
The first volume gives some predominance to the night bombing offensive, which is understandable.
Anyone interested in this should also check the volume 2, which covers the daylight offensive in more detail. There are some interesting accounts that i've read earlier in "Clash of Eagles", by Martin W.Bowman, and this title is a perfect companion for these two volumes.
In short, well worth the money, and if you're interested in the topic, either from the historian or the modeller's point of view, you won't be disappointed. Highly recommended.
