Overall 3.5 – 4 stars. 'Reign of Iron' begins with the two maiden voyages of America's first ironclad ships before their historic battle in Hampton Roads during the Civil War. The Confederacy's Virginia comes out guns blazing and rams the USS Cumberland, sinking it and then firing mercilessly on the US Congress. In the race down the East Coast to meet her rival, the Yankee's Monitor nearly sinks as it's towed in heavy seas. This 5-star portion of the book is followed by some Civil War background and how the north lost the Gosport Naval Yard in Norfolk, Virginia. Northern troops were fooled into fearing the imminent takeover of the huge ship facility so burned the yard's buildings and ammunition as well scuttling and burning its ships to avoid property falling into the hands of the Southerners in the early days of the Civil War. This 4-star story explains how the USS Merrimack came to fall in the hands of the Confederacy when the Southerners took over the yard and raised the ship whose temperamental engines, boilers and hull would become the CSS Virginia.
There are no drawings or photos of either ship in the book, except the cover. I found Drachinifel's video on youtube about the ships and the battle full of the missing paintings, drawings and few existing photos of the ships to be quite helpful.
A more mundane but well-researched 3-star story then presents the race to develop these revolutionary ironclads: their design, financing, engineering, construction and outfitting challenges. These chapters alternate between the North, under Navy Secretary Gideon Welles, building the USS Monitor battery and the South, under Navy Secretary Steven Mallory, rebuilding the Merrrimac into the ironclad Virginia in their race to launch the first ironclad. During the lengthy description of this process, we learn of the fascinating career of John Ericsson, the inventor of the Monitor and the challenges of iron plating in this time period.
Finally, we get to the battle between the two ships which we have patiently been waiting for and back to a five-star story. The two ships' overwhelming ability to dish out and take punishment is amply described. The aftermath of the first day's battle between the ships is then described and, to avoid any spoilers, the final disposition of both ships. Though both suffer embarrassing ends, their legacy was the end of the construction of wooden warships.
