It's been 147 years since the sounds of cannon and rifles echoed through the woodlands surrounding a little whitewashed church in southern Tennessee in what would become one of the bloodiest battles during the Civil War.

This weekend, visitors to Shiloh National Military Park can get a glimpse of what life was like for soldiers in the Battle of Shiloh.

Park ranger Joe Davis said about 150 re-enactors dressed in Civil War attire will help the living history programs.

"The re-enactors will be demonstrating battlefield maneuvers and firing rifles; we will have a campsite and other demonstrations so our visitors can get a taste of the battle," he said.

Davis expects more than 8,000 people.
