In vivid detail is told the story of the Army of the Potomac during the years- 1861-62, when it was under the command of the gifted but vacillating young General, George B. McClellan. Here are the Peninsula Campaign, Second Bull Run, the miracle of finding Lee's orders which led seemingly to sure victory at Antietam but turned instead into a bloody stalemate, a massacre. The other side of the coin -- in many respects -- from Williams' Lincoln Finds a General (P. 491-1949), and a more balanced appraisal of McClellan than most. Treasure trove for the strategy students of the Civil War period, with some fresh angles on this segment of the war. This will provide military technicians with new battlegrounds to explore.
