"No general surpassed him in audacity and aggressiveness. If McClellan took no risks, Lee perhaps took too many. He preferred the bold offensive, seeking in true Napoleonic fashion to destroy, not merely defeat, the enemy army. Dedicated to winning a battle of annihilation, he sometimes imprudently continued attacking beyond any reasonable prospect of success. Lee also needed to broaden his view of the war. Exhibiting a narrow parochialism, he believed Virginia was the most important war zone. He underestimated the problems Confederate commanders faced in the western and trans-Mississippi theaters and the significance of those theaters for southern survival. Yet Lee served the South well. Although costing the Confederacy dearly, his victories against great odds buoyed Confederate morale and depressed the North. Furthermore, Lee's emphasis on his native state was not entirely emotional. Richmond, the South's primary industrial center, acquired great symbolic value, and the Virginia countryside furnished men, mounts, food, and other logistical assets."
