It belongs to the North Carolina Department of Natural and Cultural Resources and is the site of the 1865 Battle of Bentonville, fought in the waning days of the American Civil War. It was declared a National Historic Landmark in 1996.Description and historyThe Bentonville Battlefield is located in southern Johnston County, roughly midway between Newton Grove and Bentonville. The visitors center is located at the junction of Harper House Road and Mill Creek Church Road (County Roads 1008 and 1108, respectively). It is roughly at the southwestern corner of the area in which the battle took place, which extends most of the way to Bentonville, and is also the location of the Harper House, the only surviving building from the time of the battle. Evidence of earthworks erected by both Union and Confederate forces is visible in the agricultural fields in this area.The Battle of Bentonville was fought March 19–21, 1865, and was the largest Civil War battle fought in North Carolina. The Confederate defeat marked a serious weakening of one of its last surviving major armies, but was a significant enough engagement that it convinced Union General Ulysses S. Grant to leave General William T. Sherman in North Carolina, in order to further subdue the surviving forces led by General Joseph E. Johnston.
