Appalachian History Series – Turning the Gap: Bull’s Gap, November 11 to 13, 1864
Bull’s Gap was never just a notch in Bays Mountain. By the time the Civil War reached East Tennessee, it was a road, a railroad pass, a military position, and a prize. The East Tennessee and Virginia Railroad ran through the gap, tying Knoxville to Greeneville, Bristol, and the lines that led toward Virginia. In a mountain war, where wagons struggled over poor roads and armies lived by railheads, a place like Bull’s Gap could decide whether men were fed, ammunition moved, and reinforcements arrived in time.
The town and pass sat in the rough country between Greeneville and Morristown, near the edges of Greene, Hawkins, and Hamblen counties. The ground itself shaped the fighting. Roads narrowed. Ridges rose on both sides. A small command with artillery and earthworks could delay a larger one, but the same mountains that protected a position also made it vulnerable to being turned by men willing to march through side roads and gaps after dark.
That is what happened in November 1864, when Confederate Major General John C. Breckinridge moved out of southwestern Virginia into East Tennessee and struck at Brigadier General Alvan C. Gillem’s Federal command. The fight at Bull’s Gap lasted from November 11 to November 13. The disaster that gave it its lasting nickname came in the early hours after the position was abandoned, when the Federal retreat toward Russellville collapsed into what Union veterans later remembered as the “Bull’s Gap Stampede.”
East Tennessee Late in the War
By the fall of 1864, the Confederacy was shrinking, but East Tennessee remained contested. Knoxville had been held by Federal forces since 1863, yet Confederate cavalry and infantry still operated across the upper valleys, especially near the Virginia line. These mountains were not a quiet rear area. They were filled with Unionist communities, Confederate families, deserters, scouts, guerrillas, foragers, and soldiers who knew the roads better than many generals did.
Breckinridge’s purpose was practical as much as strategic. His department needed food, forage, horses, and control. Federal cavalry had been ranging up the valleys and threatening the railroad approaches toward Bristol. If Gillem’s men could push too far east, they could threaten Confederate supply and communication lines. If Breckinridge could drive them back, he could reopen parts of East Tennessee to Confederate use and give his command room to breathe.
Gillem, commanding a mixed Federal force, had advanced beyond Greeneville but fell back before Breckinridge’s movement. His line settled at Bull’s Gap, where the railroad, road, and fortifications gave him a strong defensive position. His command included Tennessee Union cavalrymen who had their own personal stake in the war. For many East Tennessee Unionists, fighting here was not an abstract contest between armies. It was fighting near home, on roads their families knew, in a region where political loyalty could determine exile, imprisonment, or survival.
Breckinridge Comes Down the Railroad
Breckinridge gathered a difficult force for the expedition. It included John C. Vaughn’s Tennessee troops, Basil W. Duke’s cavalry, dismounted men, artillery under Major Page, and later reinforcements from Colonel John B. Palmer’s North Carolina command. These were not fresh parade-ground troops. They had marched through hard weather, bad roads, and a department strained by shortages. Duke, who had served with John Hunt Morgan’s cavalry and later wrote one of the important Confederate veteran accounts of the war, remembered the movement as part of the last hard service of Morgan’s old command.
Duke’s men pushed Gillem’s rear guard from the direction of Lick Creek toward Bull’s Gap. On November 10 and 11, Confederate pressure built around the Federal position. The gap was not an easy thing to take by direct assault. Gillem’s men had artillery, breastworks, and the advantage of ground. The Confederate approach required men to climb steep ridges under fire, cross ravines, and attack works swept by cannon.
On November 11, Confederate forces attacked in the morning and were repulsed by about late morning. Artillery continued through the day. The action showed both sides what kind of fight this would be. Breckinridge could not simply ride over Gillem. Gillem could not ignore the growing Confederate effort to feel around his flanks and rear.
The Assault of November 12
The hardest fighting came on November 12. Breckinridge designed a coordinated attack against the Federal front, flank, and rear. Duke’s later account described the plan in detail. Dismounted men and cavalry were sent against the Federal right, while Vaughn was expected to strike in the rear and other troops demonstrated toward the front. Breckinridge hoped the pressure would come together at the same time and break Gillem’s line.
The terrain fought for the Federals. The Confederate assaulting party climbed a steep mountainside and reached ground broken by spurs and ravines. Earthworks stood across the narrow ridges. Federal artillery could fire directly and across the approaches. Duke wrote that the position was “exceedingly strong,” and his account makes clear why the Confederates suffered so heavily. Men could get close. Some could reach or even carry outer works. Holding them under fire from the forts was another matter.
Breckinridge personally led or closely directed part of the assault. Colonel Ward’s men pressed forward with determination. On one side, Confederates drove into a line of works, only to be forced back by fire they could not silence. On another, Duke’s men came within yards of the earthworks before the Federal fire halted them. Duke believed the delayed attack in the rear allowed nearly the entire Federal force to concentrate against the main assault. Gillem’s report later said some Confederate dead were found inside the breastworks, a grim sign of how close the attack came.
The Confederate assault failed to carry the position, but it did not end the danger. Gillem had held the gap, yet his supplies were running down. His command had been under pressure for days. Horses were hungry. Bread was gone or nearly gone. Ammunition was low. In a fixed position, courage mattered, but so did cartridges, forage, and food.
The Long Day of November 13
On November 13, the fighting continued, but the Confederates did not repeat the same costly frontal assault. Breckinridge now looked for a way around the Federal position. Palmer’s reinforcements had arrived from North Carolina, but Breckinridge decided not to keep throwing men up the defended mountain. Instead, he moved through Taylor’s Gap, west of Bull’s Gap, hoping to get into Gillem’s rear and onto the line of retreat toward Knoxville.
This was the moment when the battle shifted from holding breastworks to saving a command. Gillem understood that his position could become a trap. His men were short of food and ammunition, his animals were failing, and Confederate movement threatened the road behind him. Late on the night of November 13, he withdrew from Bull’s Gap toward Russellville.
The withdrawal itself was not immediately destroyed. Much of the Federal command, artillery, and trains moved out. But a retreat at night through mountain roads is one of the most fragile operations in war. A column stretches out. Wagons slow the march. Rumor travels faster than orders. Darkness turns every sound into a threat. When the rear of Gillem’s column was struck near Russellville, the Federal retreat broke.
Russellville and the Stampede
The worst of the affair came after Bull’s Gap had been abandoned. Confederate reports and later newspaper accounts emphasized that Breckinridge had “turned” the position. Around the early hours of November 14, Vaughn’s and Duke’s commands struck Gillem’s retreating column near Russellville. The result was not a neat battle line. It was confusion, flight, captured guns, broken wagons, abandoned equipment, and men trying to escape down the road toward Morristown and Strawberry Plains.
Gillem’s own report was blunt. He called it a terrible reverse. He said his command had lived for days without bread, that horses were starving, and that ammunition was exhausted. He also wrote that when the rear was attacked, the men became panic-stricken and could not be rallied. This was the language of a commander trying to explain not only a defeat, but the sudden collapse of a force that had fought well at the gap itself.
Confederate accounts naturally told the story differently. Duke remembered the pursuit as a moonlit, night-long chase. His cavalry struck the Federal column again near Cheek’s Cross Roads and continued pressing toward Morristown. The Richmond and New York newspapers soon carried reports of prisoners, captured colors, artillery, caissons, wagons, teams, and ambulances. Numbers differed depending on the source, as Civil War casualty and capture reports often did, but all sides agreed that Gillem had suffered a serious defeat.
The phrase “Gillem’s Stampede” came from the memory of the retreat more than from the fighting in the works. Union veterans of the 13th Tennessee Cavalry preserved that name in their regimental history. To them, Bull’s Gap was not only a tactical position. It was a night of broken order, lost guns, desperate roads, and men who had survived the assault only to be swept up in the panic of retreat.
The Road to Strawberry Plains
Breckinridge followed the Federals toward Strawberry Plains, near Knoxville. There, the situation began to change. Federal reinforcements arrived. Weather worsened. Roads and streams became harder to manage. A successful pursuit in East Tennessee could quickly become a problem for the pursuer. The farther Breckinridge moved from Virginia, the more difficult supply and retreat became.
The Confederate victory at Bull’s Gap was real, but it was also temporary. Breckinridge had driven Gillem back, captured material, and shaken Federal plans in East Tennessee. He had shown that Confederate forces could still gather strength and strike hard in the mountains late in 1864. Yet he could not permanently retake Knoxville or restore Confederate control over East Tennessee. After the pursuit and fighting around Strawberry Plains, he withdrew most of his force back toward Virginia.
For the people along the road, temporary did not mean harmless. Armies passing through meant fences burned, horses taken, food seized, and families questioned by whichever side held the road that day. East Tennessee’s Civil War was full of these smaller disasters. The same railroad that made Bull’s Gap valuable to generals made nearby farms and towns vulnerable to repeated military use.
The Men Behind the Reports
The Official Records preserve the military skeleton of the campaign. They name the commanders, dates, movements, and losses. Gillem’s report gives the Federal explanation for the evacuation and rout. Breckinridge’s report explains the Confederate plan to attack front, flank, and rear, then turn the gap through Taylor’s Gap. Vaughn’s dispatches show the difficulty of timing movements through mountain roads. Palmer’s report reveals how Confederate forces from western North Carolina tied into the East Tennessee campaign. Samuel Tool’s account adds more detail to the fighting around Russellville and Morristown.
But the battle also belongs to the regimental histories and veteran memoirs. Scott and Angel’s History of the Thirteenth Regiment, Tennessee Volunteer Cavalry, U.S.A., keeps alive the Unionist memory of the stampede and the service of East Tennessee cavalrymen. Duke’s History of Morgan’s Cavalry gives the Confederate side with the vividness and bias of a man writing about his own comrades. Read together, these sources show why Bull’s Gap should not be reduced to a simple Confederate victory or Federal failure. The battle was both.
The Federals fought hard on November 11 and 12. The Confederates attacked with courage against brutal ground. Breckinridge made a costly assault, then wisely chose maneuver. Gillem held the gap, then withdrew when his supplies and line of retreat made staying dangerous. The disaster came when an exhausted command, moving at night and under pressure, lost cohesion near Russellville.
What Remains at Bull’s Gap
The landscape still matters. The National Register record for the Bulls Gap Fortification identifies the site as a Civil War military resource in Greene County, connected to the larger archaeological resources of the Civil War in Tennessee. Preservation groups have noted surviving portions of the redoubt, possible rifle pits along the military crest, and the continuing relationship between the old gap, the railroad, and the town.
The later town of Bulls Gap grew from the same geography that made the place valuable in wartime. Rail lines, roads, commercial buildings, and historic houses marked the postwar community, but beneath that later growth remains the older military story. During the war, this was a fortified pass. Men fought for it because the mountains gave them no better route.
Visitors looking at Bull’s Gap today should imagine more than a battlefield marker. They should picture hungry horses, artillery posted above rail approaches, Federal cavalrymen behind breastworks, Confederate troops climbing under fire, and a retreating column stretched out in the dark toward Russellville. The place is not famous like Gettysburg or Chickamauga, but it explains something essential about the Civil War in Appalachia. The war was often decided, or at least prolonged, by who could hold a road, bridge, ford, tunnel, depot, or gap.
Why Bull’s Gap Matters
Bull’s Gap mattered because it joined geography to strategy. It was a narrow mountain passage carrying a railroad that both armies needed. It mattered because East Tennessee remained politically and militarily unsettled even late in the war. It mattered because local Unionists and Confederates fought in a landscape where the front line often ran through families and neighborhoods.
The battle also matters because it shows the limits of victory. Breckinridge won at Bull’s Gap. Gillem retreated in disorder. Guns, wagons, horses, and prisoners were lost. Yet the Confederate success did not reverse the larger course of the war. Knoxville remained in Federal hands. East Tennessee remained beyond full Confederate recovery. Within months, the Confederacy itself would collapse.
Still, for the men who fought there, and for the people who lived along the railroad, Bull’s Gap was no small event. It was three days of fighting, a night of panic, and another scar in a region already worn down by divided loyalties and constant military movement. The gap that once guided travelers through Bays Mountain became, in November 1864, a place where the last hard months of the Civil War in Appalachia passed through fire.

Author Note: Bull’s Gap is one of those East Tennessee Civil War stories where geography decided what armies could and could not do. I wrote this piece because the fight, the railroad, and Gillem’s retreat show how hard the war still struck Appalachia in late 1864.
Came to this site looking for information on the 9th Tennessee Cavalry unit. Thanks for your interesting work in documentation of this battle.
