A two-time Newbery Honor Book author, Jim Murphy is among the world's finest writers of nonfiction for children. In A Savage Thunder he takes listeners back to the American Civil War to tell the terrible yet extraordinary story of the Battle of Antietam. With the entire world watching, two armies met in Maryland in 1862. The Union needed a victory. The Confederacy hoped to continue its success. When the smoke cleared, 23,000 men were dead or wounded-and the momentum had shifted to the Union.
