This book aims to present the Second World War from the Soviet perspective by using documents from formerly closed Soviet archives and memoirs only recently published in their full length (ie those written by Zhukov and Rokossovsky, respectively).
While the non-Russian reader can only welcome such an attempt, Prof. Bellamy's book suffers from some major shortcomings, one of which is the apparent inability of its author to read German language sources. Some errors (German ambassador von der Schulenburg is misspelled as "Schulenberg" throughout the book) could have been avoided.
But the major shortcomings are in the material presented for the Soviet side. Bellamy avoids discussing the Soviet pre-war military strategy and doctrine in a separate chapter, even though he rightly writes about the entirely offensive deployment and strategy vis-à-vis Germany. When military strategy is discussed, however, he erroneously attributes the Soviet's doctrine on the eve of the war to Svechin ("Strategy") instead of to Vladimir Triandafillov ("The nature of operations of modern armies") and Isserson.
Another major topic that is missing in this book is the Soviet Order of battle on June 22, 1941. Strangely enough, the well known German Order of Battle is given in the book, but no details about the Soviet deployment along the German, Hungarian and Romanian border. This is a very disappointing fact, especially because one would have wanted to compare the striking similarities in the deployment of the opposing forces. For very detailed information about the Soviet Order of Battle I can only refer the reader to the detailed works of Charles Sharp and Craig Crofoot for the ground forces and to Christer Bergström's about the Soviet Air Forces.
Overall, this book is not bad, but full of missed opportunities.
