content: Although exploring nothing new about the Eastern Front and even making some mistakes in the introduction (for example about the Red Army Purges) this book is a very good source to have for the general account and movement of the German Army throughout 1941 on the Eastern Front as well as the respective response from the Soviet side. Although more sources could and should have been used, I can understand why they were not, as the book would be too cumbersome and hard to follow. Detailed studies can be found in various other books of individual unit actions, but that is not what this book is for. If one has an interest in a certain action and/or day that an event occurred on, they can do their own research with this book being their beginning general account/source.
