The history of the USS Monitor, written with panache, sophisticated understanding, and attention to detail by deKay (Chronicles of the Frigate Macedonian, not reviewed). The Monitor may have been a ``doughty little Civil War ironclad,'' as deKay writes, but it was an elegantly minimalist mechanical marvel, a milestone in naval technology, with a design so original (including a revolving turret), it had 40 patentable innovations. At a time when naval strategy relied upon ships of the line--colossal square riggers with 120 guns and a crew of up to 1,200--the Monitor was a freak and a harbinger: armor-clad, steam- powered, with a mere two guns and a crew of 58. It was hardly the first of its kind--the king of Syracuse had an armor-plated vessel in the third century b.c., and Fulton's Clermont was steaming along in 1807--yet it was the right ship, in the right spot, at the right time. DeKay tells the Monitor's story with building suspense: It was the brainchild of the Swedish engineer John Ericsson, which became the best hope of the Union forces to maintain a critical blockade at Hampton Roads, Va. Finally, the author relates the wicked confrontation with the Confederate's ``awesome dark monster,'' Merrimac, another ironclad whose tale deKay sharply limns. It was a standoff at first, then the smaller Monitor exploited its opponent's unwieldiness to gain ascendancy. DeKay's tale is a richly brocaded one, serving up the sweetheart deals and political shenanigans that marked the Monitor's progress; elaborating on the rumors that flew before the epic battle like expectations before a championship heavyweight fight; bringing into play the weather and tides and most any other thing that touched upon events. This book is, simply, a little treasure. (25 b&w illustrations, not seen)
