Awesome Book for lovers of history and battles.
Format: Hardcover
This book is a great addition for a history lover or a military history lover. It would make a nice coffee table book too. Information is arranged in an easy to understand grouping throughout the book. Illustrations add to the book too. It is a heavy well made book.
