What are the motifs in The Killer Angels by Michael Shaara?

Pride in the American South is a recurring idea in this book. Pride appears to be the author's main theory on the cause of the war. The South has been told that slavery is wrong and should be abolished. The South sees this as the North's way of telling them how to live their lives. The Southern way of life is a tradition that goes back to the days when the first settlers came to America. The Southern way of life is about honor and chivalry, about social standing and outward appearances.
