"Prairie Grove is recognized nationally as one of America's most intact Civil War battlefields. The park protects the battle site and interprets the Battle of Prairie Grove, where on December 7, 1862, the Confederate Army of the Trans-Mississippi clashed with the Union Army of the Frontier resulting in about 2,700 casualties in a day of fierce fighting. This marked the last major Civil War engagement in northwest Arkansas." (Quoted from battlefield website)
"The Archibald Borden House is the only structure in the Prairie Grove Battlefield State Park that is located on it's original site. The house was the site of some of the heaviest fighting in the engagement that took place on December 7, 1862."
