This rather short book gives an in-depth description of the events of Operation Barbarossa. The author is very precise in detailing the military operations of the opening of the German war on the Russian front. The maps can be a little hard to decipher for someone not familiar with Poland and the western part of Russia, but they are a great aid to the text. One wishes that the book was longer and covered Hoth's entire career in WWII. But, within its narrow focus, this book counts as a must read for those interested in this part of the war.
N.B. Hoth strictly concerns himself with the military battles and maneuvers. If you want to learn about the political or human aspects of the war, this book covers very little of the former and none of the latter.
