Explore the battle of Antietam and the Maryland Campaign with maps

We've prepared a number of maps to help you visualize the action on that long day of 17 September 1862, and on the days leading up to the battle. Most of them contain links to more details about the military units they portray so you can dig deeper.

We have 13 individual battle maps based on the work of the Antietam Battlefield Board of the 1890s, giving you snapshots of the combat, in short time segments throughout the day. Begin at the Battle Map page.

In 1897 the Board placed 217 iron markers across the battlefield to note the positions and actions of the major army units of both sides. Follow the battle action on those markers, starting with the Tablet Map page.

You can also look at how the armies moved in the days before the battle at Sharpsburg. We've got maps for 4 - 13 September, so far. Get oriented on the Campaign Map page.

We also have a gazetteer for you - to help you find all those historic locations on a modern (Google) map.
