This is a list of the 217 iron information markers erected by the Antietam Battlefield Board in about 1897 at the direction of the US War Deprtment. They mark positions of the military units at the battle and describe their movements and engagements. The texts used here are from the original Battlefield Board records, updated as needed to match the actual (surviving) tablets.
Click on a Tablet name to see the text.
They are listed here in the order in which the events occurred. Click on "Tablet #" or "Subject/Heading" headers to sort by either of those, instead.
See our featured article for more about how these Tablets came to be. To find tablets by position on the battlefield, see our Tablet Location Maps
