Makes me want to read “The Killer Angels” all over again!
After you re-read “The Killer Angles”, you may want to tackle Jeff Shaara’s 4 book series on the war in the West.
“A blaze of Glory” about Shiloh, “A Chain of Thunder” about the Siege of Vicksburg, “The Smoke at Dawn” about Chattanooga and Lookout Mountain, and the last book of the series “The Faithful Lightning”. This covers Sherman’s March through Georgia and the Carolina Campaign. His writings are in the same style as his fathers. All are very good reads if you like Historical novels.
