Interview With Tom Clemens, Editor of The Maryland Campaign of September 1862, Vol. 1: South Mountain

I recently finished reading “The Maryland Campaign of September 1862, Vol. 1: South Mountain.”  This is the first of a two part series edited by Tom Clemens.  Clemens is a professor of history at Hagerstown Community College and received a doctorate of arts in history education from George Mason University.  An expert historian on the Maryland Campaign, Clemens’ vast knowledge of the campaign is evident in the wonderful footnotes that grace this book.

Colonel Ezra Carman was commissioned as lieutenant colonel in the 7th New Jersey Volunteer Infantry on September 9, 1861.  He would be wounded at the Battle of Williamsburg on May 5, 1862.  Upon returning to duty, he would be promoted to colonel and would actively recruit the 13th New Jersey Volunteer Infantry.  He would lead his regiment during the Maryland Campaign, Chancellorsville and Gettysburg.  Carman would temporarily lead a brigade to extinguish the New York Draft Riots.  He would be transferred to the Western Theater, with the XII Corps, and would participate in the Battle of Chattanooga and the Atlanta Campaign.  He would receive brevet promotion to brigadier general on March 13, 1865.  After the war, Carman would become chief clerk of the U.S. Department of Agriculture and would be a historical expert on the Maryland Campaign.  He was the superintendent at the Chickamauga-Chattanooga National Battlefield.  His first love, however, was as a historian.  His manuscript on the Maryland Campaign would occupy much of his time after the Civil War.  He would use firsthand accounts from commanders and soldiers to write his manuscript in addition to regimental histories and newspaper articles.  As Clemens told me, in our interview, the Carman manuscript would be used by other historians to write their narratives on the Maryland Campaign.  While the manuscript does contain some biases, it is still the definitive work on the subject.

Clemens did a masterful job of editing Carman’s manuscript.  His publisher, Savas Beatie, LLC, worked with him to ensure that the footnoting appears on the same page as Carman’s text.  This makes reading the book, and digesting the editor’s footnotes, a much easier experience.  I find myself often skipping footnotes, in other books, when I have to go to the end of the chapter or the notes section.  In “The Maryland Campaign of September 1862,” I read all of the footnotes in their entirety and it made Carman’s manuscript much more enjoyable to read.  I would often find myself chuckling while reading them as Clemens injected sarcasm and humor into his notes.  You will inevitably have an appreciation for Carman’s work, and Clemens’ research, when you read the book.  These footnotes alone make this book a great value.  Clemens also supports his editing of the manuscript with wonderfully unique maps.  The maps are in the front of the book and were created by cartographer Gene Thorp.  They are easy to understand and support the book well.

“The Maryland Campaign of September 1862” is intelligently organized.  The “Forward” was written by Ted Alexander, historian at Antietam National Battlefield.  Clemens’ well written “Introduction” is followed by the important section “Note on the Carman Manuscript” which provides detailed information on the manuscript and the challenges it presented Clemens during the editing process.  The chapter breakdown follows.

  1. Maryland
  2. The Confederate Invasion of Maryland
  3. The Confederate Army Crosses the Potomac
  4. General McClellan and the Army of the Potomac
  5. Advance of the Army of the Potomac from Washington to Frederick and South Mountain
  6. Harper’s Ferry
  7. South Mountain (Crampton’s Gap), September 14, 1862
  8. South Mountain (Fox’s Gap), September 14, 1862
  9. South Mountain (Turner’s Gap), September 14, 1862
  10. From South Mountain to Antietam
  11. McLaws and Franklin in Pleasant Valley

The chapters are followed by an Appendix 1: Organization of the Armies followed by the Bibliography that makes it readily apparent how difficult Clemens editing project was.

I would highly recommend “The Maryland Campaign of September 1862, Vol. 1: South Mountain” to any serious Civil War student or enthusiast.  I’m certain you will find the book extremely interesting and enjoyable to read.

I was able to interview Tom on August 2, 2010.  As always, I have broken the 90 minute interview into multiple parts to make it easier to enjoy; you can listen to the parts at your leisure and come back to the next part when your time allows.

About Michael Noirot

I grew up in the Central Illinois farming community, of Dunlap. Growing up, I played sports, tinkered with cars and enjoyed photography. While I did well in school, I did not become passionate about history until my early 30's. I have built a large library, of books on early America, politics and the Civil War. I am an avid reader. Fortunately, I have had plenty of opportunities to travel, over the years, and have been to most of the Civil War battlefields. I work while I travel, so more often than not, I am up, in the middle of the night, to get sunrise pictures, or I will be out until well after dark, exploring Civil War battlefields. I have other hobbies, and passions, that I really enjoy. Number one on the list would be guitar. I play my guitars on a regular basis, and enjoy the Bluegrass, and Contemporary Christian (CCM) genres. I play a style of guitar, called FLATPICKING, where using a flat pick, you play lead solos, similar to the way a fiddle would have been played during the 19th and early 20th Centuries. Laura, my wife, and I also enjoy scuba diving, travel and spending time at our property, in the country. Lastly, we spend as much time with our families, as possible. Thanks for stopping by.
