Here is a video battle animation I have made of the Sunken Road at Antietam, it is historically accurate and features a historically accurate map and correct unit placement/types. I believe this is a great way to generate a broader interest in history and it's a heck of a lot of fun to play!
The game is Empire: Total War and the mod I am using is ACW 3.6.2
Here is the link to the video if you'd like to get an idea in your mind's eye of what it might have been like to fight at the Sunken Road:
I highly recommend this game to anyone interested in the period between 1700 - 1865! =)
