<P>The battle at Fredericksburg, Virginia, in December 1862 involved hundreds of thousands of men; produced staggering, unequal casualties (13,000 Federal soldiers compared to 4,500 Confederates); ruined the career of Ambrose E. Burnside; embarrassed Abraham Lincoln; and distinguished Robert E. Lee as one of the greatest military strategists of his era. Francis Augustín O'Reilly draws upon his intimate knowledge of the battlegrounds to discuss the unprecedented nature of Fredericksburg's warfare. Lauded for its vivid description, trenchant analysis, and meticulous research, his award-winning book makes for compulsive reading. <P></P>
