Union forces intent on better securing eastern Tennessee for the federal government march in mid-January 1864 on Dandridge, Tenn., not far from a vital rail supply line linking eastern Tennessee and Virginia. The Union advance forced Confederate Lt. Gen. James Longstreet to fall back. But on Jan. 17, 1864, fighting erupted between the opposing forces. Confederates backed by artillery and Cavalry forced the Union fighters under Brig. Gen. Samuel D. Sturgis into retreat by nightfall. But for lack of more shoes, supplies and ammunition the Confederates were unable to destroy the federal forces outright.
