The book handles personalities of both individuals and cultures and their effects on the war. The reading can be slow going at times as armies march toward each other and the order of battle becomes established with the commanders names and stations, but the battle details seem incredibly well researched and the accounts of individual soldiers/officers bring home the reality of this conflict.
This book is well worth the effort to read, it imparts a sense of what the United States has survived and clarifies many historical perceptions of the era and the people involved in this massive conflict. My only suggestion, keep a note pad at your elbow as you read this book, it is slow going and you'll need to take notes about commanders and places to keep it all straight in your head.
