The Battle of Devil's Backbone (sometimes called the Battle of Backbone Mountain) was fought on September 1, 1863 when Confederate Brig. Gen. W.L. Cabell took up a series of hidden positions behind natural stone breastworks on the Devil's Backbone, an imposing mountain south of Fort Smith. Union troops under Col. William F. Cloud of the 2nd Kansas Cavalry ran headlong into Cabell's ambush.
The resulting battle was noisy and intense, as each side poured artillery fire on the other, but casualties were relatively low. Despite some initial success, Cabell's chance for victory evaporated when most of his forces suddenly retreated from the field.

This is really exciting news as it means that a portion of the critical historic site will be preserved for future generations.
