In Jefferson County, Tennessee, the Civil War touched small towns, farms, houses, and mills as communities were swept into a conflict that divided some residents over secession and slavery in a "war within a war" that left deep scars. Tennessee seceded and supplied 120,000 soldiers to Confederate armies, but United States sentiment remained strong, especially in East Tennessee, and 31,000 white Tennesseans fought for the Union, more than in any other Confederate state. The war in Tennessee also included the self-emancipation of some of the state's 275,000 enslaved men and women and the service of 20,000 self-liberated warriors in the U.S. Colored Troops. More battles were fought in Tennessee than in any state except Virginia, and in Russellville the Nenney House, now the General Longstreet Headquarters Museum, interprets telegraph communications between Longstreet and his subordinates.
