Key Revolutionary War battles detailed in the book include the Battle of Dorchester Heights, the Battle of Long Island, and the Battle of Trenton.  The actual signing of the Declaration of Independence is treated as a somewhat minor detail, as the main focus of the book is on military rather than political events.  The book includes multiple pages of full color illustrations, including portraits and historical battlefield maps made by British engineers at the time.
