This is the best book yet in Bergstrom's series studying operational air warfare on the Eastern Front in World War II. In this part Bergstrom seems to have had more access to command-level documentation, which really gives you the feel of the cut and thrust of how the air staffs responded to each other in a battle that was as much a turning point in the air as it was on the ground. I really can't say enough good things about it. ( )
