While the Union did have Gatling guns and they had entered manufacture by Antietam, I'm not sure if there were any present at the battle. I've looked around a bit, finding one article that implied there were Gatling guns on the Unionist side, but nothing concrete.
I'm expecting that it'll just be field guns, but I couldn't live with myself if I didn't mention it.
