This is an excellent work. It's probably the best book I've read devoted to a single battle. The analysis is almost entirely from the Russian perspective, but the other side can be gleaned from other sources. The author gained access to recently available Soviet documentation to tell the Russian side of the confrontation. This is not to say the German side is ignored, however. There is very extensive use of quotations from the Soviet General Staff Study of the battle, yet the author counters any bias. The book covers everything you'd want in an analysis: terrain, force structure, order of battle, tactical and strategic decision making, etc. The maps are better and more numerous than in those in most works of this type. The only real problem I have with it is that the author doesn't really explain why the Russian 9th Army attacked at Maiaki. This was on the southeastern end of the Barvenkovo bridgehead. It was against this southern flank that the Germans launched their counterattack that doomed the Russian offensive and the Maiaki attack weakened the Russian forces on this flank. Except to say the attack was conducted and it was a bad idea, the book fails to explain what led the Russian commander to conduct it in the first place. Nevertheless, this is a very minor complaint with what is a very excellent book.
