Index of Historical Tablets

Antietam National Battlefield Park

This is a list of the 217 iron information markers erected by the Antietam Battlefield Board by direction of the US War Deprtment in about 1897. They were created to mark positions of the military units at the battle, and describe their movements and engagements. The texts shown here are from the Board records, corrected, as needed to match the surviving tablets.1 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
