On this program from the National Writers Series, Jeff Shaara explains why General Sherman was so successful in the American Civil War. Even though Sherman is known for his "total war" strategy, Shaara says his tactics weren't as harsh as many people believe. Jeff Shaara is the author of six works of historical fiction about the Civil War. The latest is called "The Fateful Lightning." He talks this hour with Ed Tracy, CEO of Roxbury Road Creative.
