A new smart phone app will allow visitors to Perryville Battlefield State Historic Site to hear details about the pivotal battle.
The app was developed by a group of Ball State University students in Indiana.
It uses voiceovers to explain the battle and has period music and photos.
Park manager Kurt Holman says it will tell the story of not just the generals but also the experiences of common soldiers.
The students took on the job of creating the app as part of the Building Better Communities Immersive Learning Program at Ball State. They began in January and finished in May.
Perryville was the scene of the most deadly Civil War battle in Kentucky, with more than 7,600 soldiers killed, wounded or missing.
