BREAKING NEWS: Newly Discovered Map Shows Antietam Burials in Detail

Historians with the Adams County Historical Society in Gettysburg, PA, have made an exciting discovery that will help reshape our understanding of the aftermath of battle at Antietam while also shedding some new light on our understanding of the aftermath of battle at Gettysburg.

Historians Andrew Dalton and Timothy H. Smith, while researching an article about a “railroad swindler,” S. G. Elliott, discovered a newly digitized map in the holdings of the New York Public Library that shows detailed locations for burials on the Antietam battlefield.

The announcement was made today by the American Battlefield Trust, which gave ECW advanced access to materials. As part of our coverage, we’re pleased to offer exclusive interviews with Dalton and Smith, as well as Antietam National Battlefield’s Brian Baracz; details about the map and its discovery; a look at how the map will impact interpretation at Antietam; and special resources from the American Battlefield Trust. Read on!

Elliot Antietam-sm

The newly discovered Antietam map by Elliott is similar to one he had drawn that depicts the burials at Gettysburg, which historians have used for several decades. According to historian William A. Frassanito, Elliott’s Gettysburg map presented the first post-battle survey of the field, and the map has been widely influential.

The Antietam map, on the other hand, was lost to time. “Battle of Antietam historians have long-hoped that something like [the map] might exist—a wartime map denoting the location of thousands of hastily dug battlefield graves,” says Garry Adelman, chief historian for the Trust and a frequent Smith collaborator, brought in to assist with the material. “We think [this] is the only known extant copy of Elliott’s map for Antietam, which no historian or park curator is ever known to have used or referenced.”

Elliott’s map, drawn in 1864, was based on the work of others. Dalton, in his research on Elliott, discovered that the mapmaker “was nowhere near either Gettysburg or Antietam when the initial burial information was being collected.”

“His maps were undoubtedly based on the efforts of earlier surveyors,” Dalton adds, “and in the case of Gettysburg, may represent the field as it appeared within mere days of the battle.” Nonetheless, he says, “Elliott deserves credit for compiling this valuable information and having it published.” (To read Dalton’s full article on Elliott and Elliot’s maps, visit The Adams County Historical Society Digital History Blog.)

Brian Baracz, a historian at Antietam National Battlefield brought in to help with the project, counted the burial marks Elliott made on the map. “It took a good part of two days and a little help from my wife,” he says. “I took the map and created 24 sections to make it easier to count, [then] hand counted every mark on the map and checked them off as we went.” The tally came to 2,634 Union and 3,210 Confederate, for a total of 5,844 burial marks. Fifty of the individual graves have notes about the identity of the soldier buried there (as compared to Elliott’s Gettysburg map, which identifies only 18 soldiers). The location of many units are also listed on the map by name. The map also included 152 cannon marked in 29 different locations and 269 horses marked in 40 different locations. 

Baracz says Antietam National Battlefield now has a special page devoted to the map (you can see it here).

“This discovery reveals truths about the Battle of Antietam lost to time,” Adelman said in a press statement. “It’s like the Rosetta Stone: by demonstrating new ways that primary sources already at our disposal relate to each other, it has the power to confirm some of our long-held beliefs — or maybe turn some of our suppositions on their heads.”

Andrew Dalton took time this morning to talk with ECW about his research on Elliott and how that led to the map’s discovery:

Historian Tim Smith, who discovered Elliott’s Antietam map, also took some time this morning to talk with ECW. He talked about making the discovery and what it might mean for battlefield interpretation:

Antietam National Battlefield Historian Brian Baracz spoke with ECW this morning to talk about his work applying the map at Antietam:

The Trust has also compiled a variety of online sources related to the Elliott’s Antietam and Gettysburg maps:

And of course, you can also check out the map for yourself, available as a free hi-res download from the NYPL.

Finally, I want to give a special shout-out to historian Kristopher D. White, senior education manager at the American Battlefield Trust (and ECW co-founder!), for his assistance in making today’s report possible.

    What a cool find, and a great job Chris of interviewing the key players. Very exciting–and good to have such a positive story in these challenging times. Makes one wonder what other resources are waiting to be discovered, or re-discovered. Thanks for putting this together.

    • Chris Mackowski says:

      Thanks–glad you enjoyed it! The historians were all gracious with their time today, on what was surely a busy day for them.

  2. Leon Reed says:

    That’s fantastic news. My great great grandfather, John Allen, was in the 137th PA, a nine month regiment mustered in in August 1862 after 2nd Manassas. They were at Antietam and were one of the regiments kept behind to bury the dead, So the map in part represents his work.

  3. Makes my nerdy heart happy! Yes, all those tick-marks! Found some for the 9th LA north of the West Woods area. Fascinating stuff.

  4. W Charles Young says:

    This could be such a huge find. It just goes to show there is more material out there to find. Great stuff!

  5. Mike Maxwell says:

    Excellent work, and Great News!
    And to expand on the above… After the Civil War, Major E. B. Whitman was tasked with visiting battlefields, and locating all the remains for removal to National Cemeteries. He and his team completed the work four years later; and Whitman submitted a report (1869) that details precise battlefield measurements, and includes maps… but the Report is held at the National Archives, and requires personal visit to gain access https://www.cem.va.gov/cem/history/timeline/timeline-1869.asp

  6. Todd Berkoff says:

    Does this map shed any new light on the total number of fatalities at the battle? I realize that many of the Confederate dead–nearly 2800 by most accounts–were eventually relocated to various private cemeteries in nearby West Virginia and western Maryland. Moreover, some of the Union dead were also relocated to private cemeteries in the years after the war.

    Interestingly, the total number of Confederate burials of 3200 is consistent with George McClellan’s after-action report, in which he gives the figure of approximately 3000 CS dead that his army buried on the field.

    The official casualty figure from the NPS is 2100 US and 1560 CS killed outright (3600 total) on September 17th and another 4000 that died of wounds (includes the 1750 counted as missing that were probably killed), for a grand total 7600 killed and died of wounds. James McPherson’s book Crossroads of Freedom (2002) provides a slightly lower total number fatalities at 6500 (4300 killed outright–2300 US and 2000 CS dead–and 2200 died of wounds).

  7. If I were trying to determine why so few of the maps of Gettysburg and Antietam now appear to exist, I would do some digging in the business files of the Lloyd company. If Elliot had not paid for the contracted work, there would be a question about ownership of the product and Lloyd might have been reluctant to sell copies. Since the apparently single copy of the Antietam battle map ended up in the resources of the NY Public Library, I would wager that other pieces of Lloyd’s history, business and more generally, are also there.

  8. Todd Berkoff says:

    Can we please relocate the Visitor Center now? Not only does it sit on key high ground crucial to understanding the tactical fight, but there were hundreds of US and CS dead buried on the site and some probably still rest there today!

  9. Joe says:

    When will this map be available to buy?

  10. win53 says:

    Awesome stuff

  11. ron walker says:

    Very interesting find. Is there a key to the symbols used on the map?
