The annual Decoration Day on top of Cold Spring Mountain, above Horse Creek Park in Greene County, Tennessee. The event is held each year at the site of the graves of William and David Shelton and Millard Haire. The three men were killed there during the Civil War.
David Shelton and his nephew William had enlisted in the Union army and were returning home during the war to a cabin on Cold Spring Mountain. However, the Sheltons and Haire, who was 13 years old at the time and was acting as a scout, were ambushed by Confederate soldiers. The families buried the three atop the mountain.
According to the National Forest Service webpage the ambush occurred on July 19, 1864. Around 1915, federal grave markers for the two soldiers were hauled to the site by ox sled. In 1998, descendents of the civilian, Haire, erected a tombstone in his honor.
