For anyone intersted in Napoleonic uniforms, this is an instant classic in book form. Previously published as prints, they have long been the gold standard for French Napoleonic uniform detail. And, yes, it's all here. I have a few of the prints and the book contains all the illustrations and text of the originals.
The good bits: basically all of it. You get pretty much pure uniform detail. No operational history of the troops themselves.
On the minus side, it doesn't have information on many of the smaller units. Maybe the format could have been larger.
The cost is about the price of seven or eight Osprey titles. I love Osprey, but if you just want uniform information, this is the better bet.
If, like me, you have been into this for way too many years, you may have all those French magazines; the Uniformes and Tradition series. Well you probably have all the information already, but I'm willing to bet few will resist the temptation to buy this book. Go ahead, it's a great read.
