We are interested in Civil War history, too, and have been to three sites: Shiloh, Franklin, TN, and Ft. Donalson. We keep learning things about that era. For example, the invention of the cotton gin played a huge role in the Civil War history. An interesting book is: "At the Edge of the Precipice: Henry Clay and the Compromise that Saved the Union" by Robert Remini, about the 1850 Compromise. Another interesting book is Grant's bio. Robert E. Lee is still my favorite character because of his "character." Another favorite of mine is Stonewall Jackson.
