The Monitor-Merrimack showdown may be one of the Civil War's most overhyped chestnuts: the two ships were by no means the first ironclads, and their long awaited confrontation proved an anticlimactic draw, their cannon fire clanging harmlessly off each other's hulls. Still, the author of this lively history manages to bring out the story's dramatic elements. Nelson, author of the Revolution at Sea series of age-of-sail adventure novels, knows how to narrate a naval crisis. He gives a harrowing account of the Merrimack's initial onslaught, in which it destroyed two wooden Union warships in a bloody and chaotic battle the day before the Monitor arrived, and of the Monitor's nightmarish final hours as it foundered in a storm at sea. Equally arresting is his retelling of the feverish race between North and South to beat the other side to the punch with their respective wonder ships. He delves into every aspect of the ships' innovative design and construction, and draws vivid portraits of the colorful characters who crafted them, especially the brilliant naval architect John Ericsson, one of that epic breed of engineer-entrepreneurs who defined the 19th century. The resulting blend of skillful storytelling and historical detail will please Civil War and naval engineering buffs alike.
