The eastern West Tennessee men who joined the IL, IN, OH, IO, KS units usually did so when Grant was coming down through West Tennessee before the West Tennessee units were formed. Since the Tennessee River runs north some built rafts and floated down to meet Grant at Ft. Henry and Ft. Donelson. (Civilian Unionists used this method as well to avoid western KY. Union gunboats would pick up both groups occasionally, also.) Some volunteers were promised they could switch to the Tennessee units later and some did. When the Tennessee units formed most of the enlistment in northern units ceased. (Incidentally, the 1st Alabama and Tenn Vedette Cavalry had re-enlistments from West Tenn and AL.) As to reconciliation, up until about the 1950s you could still tell where the descendants of the Unionists lived in eastern West Tennessee because they still voted Republican in the "Solid South." As to what is taught in public school classrooms now I don't know. College textbooks do mention the Unionists and it will filter down eventually. I'm not familiar with Crockett Co except that it was mostly Confederate. The areas with the most turmoil were those that had about equal numbers of Confederates and Unionists. They carried on a war among the civilians. That lack of consensus also encouraged guerrilla and bushwhacker groups to abound.
