The Maryland Campaign of September 1862

When Robert E. Lee marched his Army of Northern Virginia into Maryland in early September 1862, Maj. Gen. George B. McClellan moved his reorganized and revitalized Army of the Potomac to meet him. The campaign that followed included some of the most dramatic marching and influential combat of the entire Civil War. Combined with Southern failures in the Western Theater, the fighting dashed the Confederacy’s best hope for independence, convinced President Abraham Lincoln to announce the Emancipation Proclamation, and left America with what is still its bloodiest day in history.

One of the campaign’s participants was Ezra A. Carman, the colonel of the 13th New Jersey Infantry. Wounded earlier in the war, Carman would achieve brigade command and fight in more than twenty battles before being mustered out as a brevet brigadier general. After the horrific fighting of September 17, 1862, he recorded in his diary that he was preparing “a good map of the Antietam battle and a full account of the action.” Unbeknownst to the young officer, the project would become the most significant work of his life.

Appointed as the “Historical Expert” to the Antietam Battlefield Board in 1894, Carman and the other members solicited accounts from hundreds of veterans, scoured through thousands of letters and maps, and assimilated the material into the hundreds of cast iron tablets that still mark the field today. Carman also wrote an 1,800-page manuscript on the campaign, from its start in northern Virginia through McClellan’s removal from command in November 1862. Although it remained unpublished for more than a century, many historians and students of the war consider it to be the best overall treatment of the campaign ever written.

Dr. Thomas G. Clemens (editor), recognized internationally as one of the foremost historians of the Maryland Campaign, has spent more than two decades studying Antietam and editing and richly annotating Carman’s exhaustively written manuscript. The result is The Maryland Campaign of September 1862, Carman’s magisterial account published for the first time in paperback in three volumes. Jammed with sweeping prose, firsthand accounts, personal anecdotes, and old-fashioned footnotes, together with stunning original maps and photos, this long-awaited study will be read and appreciated as battle history at its finest.
