LETTER FROM SWEETWATER Sweetwater, Tenn. October22, 1863

Gen. Stevenson’s division is here. Gen. Vaughn has gone on a scout today after Brice, who is at Tellico Plains. (Knoxville Daily Register)

In October 1863 just after the Battle of Philadelphia, Tennessee, Williams notified Confederate General John Crawford Vaughn of Monroe County, Tennessee that a gang of "bushwhackers" had just passed his home and headed toward the Tellico River. Vaughn took Williams and a small squadron in rapid pursuit. After having rested part of the night near Coco [Coker] Creek, Williams dressed as a Yankee soldier and scouted toward the North Carolina line ahead of General Vaughn. The company overtook Bryson's Boys at Evans' Mill on Beaver Dam Creek in Cherokee County, North Carolina. Two of Bryson's Boys were verified as killed and supposedly seventeen captured; only one of Vaughn's squad was killed. Bryson escaped this seige since he was mounted on a swifter steed.
[William Ballard Lenoir, A History of Sweetwater Valley, (Baltimore, Maryland, 1976), p. 403] The seventeen captured men forever disappeared into oblivion. Tradition has it that they were executed on the shoals of the Tellico River in Monroe County, Tennessee. http://ourworld.compuserve.com/homepages/4the3sratledges/bryson.html
