This detailed treatment of Civil War ironclads in the broader context of world naval developments has sparked a debate among U. S. Naval strategists. Many readers will learn for the first time of the influence on both Union and Confederate observers of Crimean War and other European armor, and learn the subsequent history of many Civil War naval vessels that later saw action in Peru, Paraguay, and Japan. | Ironclads At War by Jack Greene, Hardcover | Indigo Chapters
