The importance of Robert E. Lee’s first movement north of the Potomac River in September 1862 is difficult to overstate. After his string of successes in Virginia, a decisive Confederate victory in Maryland or Pennsylvania may well have spun the war in an entirely different direction. The importance of Robert E. Lee’s first movement north of the Potomac River in September 1862 is difficult to overstate. After his string of successes in Virginia, a decisive Confederate victory in Maryland or Pennsylvania may well have spun the war in an entirely different direction. Why he and his Virginia army did not find success across the Potomac was due in large measure to the generalship of George B. McClellan, as Steven Stotelmyer ably demonstrates in Too Useful to Sacrifice: Reconsidering George B. McClellan’s Generalship in the Maryland Campaign from South Mountain to Antietam, now available in paperback. In Too Useful to Sacrifice, Stotelmyer combines extensive primary research, smooth prose, and a keen appreciation for the infrastructure and capabilities of the terrain of nineteenth century Maryland. The result is one of the most eye-opening and groundbreaking essay collections in modern memory. Readers will never look at this campaign the same way again. By the time they close this book, most readers will agree Lincoln had no need to continue his search for a capable army commander because he already had one. AUTHOR: Steven R.
