I guess the "great photos" part shouldn't be a surprise, given that this is a photographic history. But every now and then new photo books hit the market that recycle trade-worn shots or offer poor photo quality for a premium price. This book isn't one of them..the photos are fine (although not every one is an action shot), the text and captions are well written and fairly engaging, and the price is not too bad. The book's only technical fault is that there are very few maps to help guide the reader--especially given the amount of ground covered during Army Group North's retreat--and to portray the tactical and strategic situation.
Nitpick Alert: OK, this book markets itself as being presented from the German perspective. Fine..no charges of false advertising here. It is something of pity, however, given the dearth of works on the late war Baltic and East Prussian campaigns that there is nothing presented from the Russian perspective. Not that the author is biased--the text is neutral, I think--but the book would have been more enjoyable had it used photos from both sides.
All-in-all, a worthwhile addition to your collection if the subject interests you. As I mentioned, there are few books out there that cover the Baltics and East Prussia in much depth, so this one is a keeper.
