The title of this review is a bit tongue in cheek. I like this book, but it is probably not for the general reader. There is a huge mass of detail provided in its pages which is more than challenging to anyone other than true aficionados of Roman fortifications. The heart of this book is what I would term a gazetteer of almost all known legionary fortresses of the Roman Empire, approximately 85 locations. Outline drawings of the plans are provided, as well as details such as regions, provinces, proportions and area, compass orientation, dating, literary references, garrison units, modern references, and geographic coordinates. Color photographs of many of the fortress features are provided and text in the front portion of the book provides some description of the functions of the various features of the fortifications. The book is well organized and has features which are unique if not stunning. This is a wealth of detail. Nothing in the book ties the fortresses to strategic analysis, the reason for the fortress being located and constructed as it was, the populations or cities they were attempting to protect, or the enemies they were trying to counter. Could some of these constructs been make work projects to keep the soldiers occupied? Were they the Roman version of stimulus spending? If they were bases and depots to counter various threats, what campaigns did they support? The grand strategy of the empire has many questions and unknown factors, but the book would have been more satisfactory by attempting to answer some of them. Within its limits this is an excellent and exhaustive work. It should be read in conjunction with The Frontiers of Imperial Rome by David J. Breeze or The Reach of Empire by Derek Williams to answer some of the more strategic questions. The Osprey Fortress series contains some excellent information of interest to the generalist.
