Appalachian History Series Bull’s Gap sits where the railroad and the road squeeze through Bays Mountain between Greene and Hawkins counties. In the fall of 1864 the gap again became the key to East Tennessee. Across three days, November 11 to 13, Major General John C. Breckinridge pressed a smaller Federal force under Alvan C. Gillem, roughly 2,500 effectives, with about 3,000 Confederates on the field.
