After describing his first battles, at Shiloh and Stone River, Captain Johnston's narrative covers the march to Chickamauga and the ensuing conflict, during which he was captured and taken to Libby Prison in Richmond. He reported on the incidents along the way, the prison, and the treatment of prisoners. Once confined, Johnston and the other inmates planned their escape, experienced some failed attempts, and eventually made their way out through a tunnel. But that was just the beginning; the run to freedom was exhausting and they were almost retaken. When he rejoined his regiment, Johnston took part in Sherman's march to Atlanta, which is explained in detail. The accounts are noteworthy for their vivid battlefield descriptions, clear accounts of the marches and locales, and observations of military strategy by one who was there. All of the commanding officers and fellow soldiers mentioned in the book are included in a new every-name index.
