Cozzens (The Darkest Days of the War
) is an independent scholar and a master of Civil War military history at tactical and operational levels. He deploys a large body of unfamiliar primary material in this detailed analysis of a campaign less one-sided than the accepted view that it represented Union blundering and the triumph of Confederate planning and execution signaling the emergence of one of history's great generals, Stonewall Jackson. Without debunking Jackson, Cozzens describes a commander still learning his craft. Jackson's obsession with keeping his strategic intention to himself too often left his subordinates confused. As a tactician he tended to commit his forces piecemeal. The Union generals opposing him performed reasonably well in the context of divided command, inadequate logistics and constant micromanaging by Abraham Lincoln. In particular the president's concern for Washington's safety led him to withhold troops from McClellan's Peninsular Campaign—a decision Cozzens reasonably says enhanced McClellan's natural caution. Jackson's victories revitalized a Confederacy whose morale was at its lowest after a string of Union victories. The South now had a new hero, whose personal idiosyncrasies and overt religiosity only enhanced his appeal. 13 illus., 13 maps. (Oct. 10)
