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 Although it remained unpublished for more than a century, many historians and students of the war consider it to be the best overall treatment of the campaign ever written.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.
"Ezra Carman’s long-unpublished history of the 1862 Maryland Campaign is an essential source on the operations that produced the bloodiest day in American military history and largest surrender of U.S. troops before World War II and there is no one better qualified than Thomas Clemens to bring it to print. Not only does this volume make Carman’s study broadly accessible to students of the war, but Clemens’s many years studying the events of September 1862 and unmatched knowledge of Carman and his work enable him to skillfully and authoritatively explain and scrutinize Carman’s take on events. In addition to being a magnificent contribution to literature on the Civil War, this outstanding book will also advance the process of securing Clemens a place alongside Carman and Harsh in the pantheon of Maryland Campaign scholars. I cannot recommend it highly enough." ~Ethan S. Rafuse, author of McClellan’s War: The Failure of Moderation in the Struggle for the Union and Antietam, South Mountain, and Harpers Ferry: A Battlefield Guide
"From reading the manuscript and Clemens's expert editing, one easily sees why modern Antietam scholars lean heavily upon Carman's pioneering work. One wishes all Civil War battlefields had been likewise gifted with such a worthy and dedicated veteran sponsor. Soon, with the completion of the pair of volumes comprising The Maryland Campaign of 1862, all readers will have easy and affordable access to a classic of Civil War historiography, as well as a mammoth editorial project of significant scholarship in its own right." ~Civil War Books And Authors
