Fred Ray, who has written several articles on the Confederate Sharpshooter for America's Civil War magazine, has finished his book. Entitled Shock Troops of The South: The Sharpshooter Battalions of the Army of Northern Virginia, it is the first modern book devoted solely to the sharpshooters in that army. Previously, only one book (Capt. Dunlop's "Lee's Sharpshooters or Forefront of Battle) has ever addressed it and Fred Ray from his articles Mr. Ray has done extensive research on the subject.
