Maybe one of the reasons that the Civil War (called the War of Northern aggression by my grandmother!) fascinates so many, myself included is because of the emotional aspect that made it unique, the issues of slavery, the brother fighting brother divides, the actual fighting on your land or near your home. I live about an hour from Andersonville, that draws lots of tourist to see the former prison camp. (It also now houses the National POW musuem, which is an extraordinary experience if you ever are near by)
One thing I have always found amusing in the Horse Soldiers. JW's character is a Yankee....but his attitude and determination remind me so much of the famous southern leaders.
