I'm a bit of a history buff, myself. Here are a couple of my favorites:

River Run Red by Andrew Ward. Nathan Bedford Forrest was the greatest Civil War General, IMHO.

Alabama's Own In France by William Henry Amerine. I love reading about The Rainbow Division in WWI. My Grandfather was recommended for the MOH in WWI. Douglas McArthur reduced it to a DSC.

White Devil by Stephen Brumwell. The story of Major Robert Rogers and his "rangers". The birth of "special forces" in North America. French and Indian War.

Hope you enjoy. I certainly did.
