At 111 pages in length, this book is hardly an exhaustive treatment of the First World War on the Eastern Front. The author does, however, address a number of important points. It all begins with a discussion of Germany's Schlieffen Plan, which called for a quick victory against France in the West before focusing on the Russians in the East. Ultimately, the Germans were forced to send some of the forces earmarked for the West to the East to stave off the Russian advance--a decision that made the trench-based stalemate in the West more likely.
As the author lays out the events that aided the able German forces in crippling the lumbering Russian army, a number of interesting facts are brought to light--not the least of which was that Tannenberg had been the site of German Army war games and maneuvers that each German officer knew like the back of his hand. What brought little help to the Germans was their Austrian-Hungarian ally--a nearly feudal entity that outmatched even the Russians in incompetence and pointless bureaucracy. The Austrians did excel in one department--that of the massive howitzers produced by their Skoda works--behemoths that dwarfed even the guns of Germany's preeminent arms manufacturer Krupp.
This book has a number of maps and photographs to help and engage the reader. Nevertheless, the author would have done well to include a few more well-marked maps. In particular, I would have appreciated a more detailed mapping of the forces deployed and movements executed at Tannenberg.
