Shock Troops of the Confederacy: The Sharpshooter Battalions of the Army of Northern Virginia by Fred L. Ray. Really good military read detailing the rise of Southern Sharpshooter (think light infantry/snipers/skirmishers) in Civil War. It is written from southern view point so sometimes the Federal troops are not shown in best of light and names of battles are little confusing, like battle at Antietam becomes Battle of Sharpsburg (town near the creek)
"We saw it…. the hussars let loose their horses. God, what power! They ran through the smoke and the sound was like that of a thousand blacksmiths beating with a thousand hammers
They rush on to the Swedes! They crash into the Swedish riters…. Overwhelm them! They crash into the second regiment - Overwhelmed! Resistance collapses, dissolves, they move forward as easily as if they were parading on a grand boulevard
