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.
I tried to get into “Gods & Generals” but I’m afraid the son was not as good as the old man. Perhaps I was too judgmental though. I’m willing to give it another go though.
I do recommend Bruce Catton’s books which I read as a child - it generated a life long interest in the Civil War. He seems to be a forgotten author these days much like the great Thomas Costain is a forgotten author on English Medieval books.
For those who like novels (and animals) about the Civil War I recommend Richard Adams’ “Traveller” about Lee’s war horse. It is an adult novel but told through the eyes of an animal. He’s the author of the classic “Watership Down” and “The Plague Dogs.”
Happy 4th, everyone!
