The Sword of Antietam - Joseph A. Altsheler

"The Sword of Antietam" tells a complete story, but it is one in the chain of Civil War romances, begun in "The Guns of Bull Run" and continued through "The Guns of Shiloh" and "The Scouts of Stonewall." The young Northern hero, Dick Mason, and his friends are in the forefront of the tale. (Summary from the Foreword)
