Though, at its heart, "Xenophon's Retreat" is a summary of "The Expedition of Cyrus" (the first, and one of the most important, military campaign accounts of the ancient world), this book is surprisingly more than just a translation.
Written with a fantastically dry wit by an author who actually retraced the life, and travels, of "The Expedition's" Greek creator, it not only tells the story of Cyrus' ill-fated uprising, but also takes a very reasonable, and enlightening, approach to the ancient Greeks as a people...providing critical background on not only Xenophon (something that was desperately lacking until now), but also the social, economic, and political forces of the world he lived in.
As someone who's read more than my share of military history, I loved the balance it strikes between the technical, the philosophical, and the practical. In particular, I was impressed with the religious and cultural perspectives it provides on history that is so often left to relatively dry statistics. Turns out it's absolutely remarkable how much more sense the military aspects of the ancient world makes once you get a glimpse at the rest of the picture.
All in all, "Xenophon's Retreat" is unlike anything else I've ever read in the field, and I thoroughly enjoyed it.
