# Battle of Mill Springs: The First Union Victory in the Western Theater

_Authored by [Joshua J. Mark](https://www.worldhistory.org/user/JPryst/)_

The [Battle](https://www.worldhistory.org/disambiguation/battle/) of Mill Springs (19 January 1862) was the first Union victory in the Western theater of the [American Civil War](https://www.worldhistory.org/American_Civil_War/) and propelled Union General [George H. Thomas](https://www.worldhistory.org/George_H._Thomas/) to fame. The battle is known by many names owing to the area in Pulaski County and Wayne County, Kentucky, in which it was fought. These include Battle of Mill Springs, Battle of Logan's Crossroads, Battle of Somerset, and Battle of Fishing Creek.

Whatever name it is known by today, it was a decisive Union victory orchestrated by George H. Thomas. His victory, however, would be quickly eclipsed by those of [Ulysses S. Grant](https://www.worldhistory.org/Ulysses_S._Grant/) at the Battle of Fort Henry (6 February 1862) and the Battle of Fort Donelson (11-16 February 1862) in Tennessee. Fort Henry and Fort Donelson are still sometimes referenced as the first Union victories in the Western theater of the [war](https://www.worldhistory.org/disambiguation/War/).

Just as Grant's victories overshadowed Thomas's, so did Grant's overall career. Even someone with only a passing knowledge of American history knows who Ulysses S. Grant was; very few know the name of George H. Thomas. Even so, Thomas's victory at Mill Springs secured Kentucky for the Union, shattered the eastern defensive line across the southern region of the state, boosted Northern morale, opened Middle Tennessee to the Union, and actually allowed for Grant's victories at Fort Henry and Fort Donelson by eliminating the threat posed by the Confederate forces in eastern Kentucky.

### Background

When the North and South divided at the beginning of the war, some states chose to remain neutral, and these were known as the border states, which included Delaware, Kentucky, Maryland, and Missouri (West Virginia would later become a border state in 1863). As neutral states, all of these remained in the Union and expected both sides to respect that neutrality.

Although pro-Confederate (and pro-Union) volunteer militias were already in the state, Confederate forces under General [Leonidas](https://www.worldhistory.org/disambiguation/Leonidas/) Polk invaded Kentucky in September 1861, taking the city of Columbus and officially violating the terms of Kentucky's neutrality. This prompted the Kentucky state legislature to appeal to the Union for assistance. Union forces under Ulysses S. Grant then took Paducah to secure the state. Although Kentucky continued to insist on its neutrality, it had now been pulled into the war.

Polk's action forced Confederate General [Albert Sidney Johnston](https://www.worldhistory.org/Albert_Sidney_Johnston/) to extend his lines because Kentucky was now no longer really neutral, and Johnston tasked Major General George B. Crittenden with holding the area of the Cumberland Gap, which was strategically important as it provided a gateway between Kentucky, Tennessee, and Virginia.

If held by the Union, the Gap would provide access to pro-Union Tennessee and allow for swift troop movements via the Virginia and East Tennessee [Railroad](https://www.worldhistory.org/disambiguation/Railroad/) that ran a few miles south of it. If held by the Confederacy, it would, of course, prevent this but also provide a defensive anchor for Johnston's army in the Western theater.

### Lead-up to Battle

Crittenden gave Brigadier General Felix Zollicoffer the responsibility of guarding the Cumberland Gap and, after securing that area in November 1861, Zollicoffer advanced toward Mill Springs to be nearer to the Confederate troops stationed at Bowling Green. Crittenden had ordered Zollicoffer to encamp on the south side of the river, but Zollicoffer believed the north side afforded a better defensive position.

There were other reasons, however, for Zollicoffer's decision: encamping on the north side of the river set his forces closer to those of the Union and allowed for greater ease in deployment for attack, and also, the Cumberland River was swollen by autumnal rain, and he did not have enough boats to move his men swiftly across it. A slow advance across a swiftly running river provided an opportunity for Union forces to attack midway, and Zollicoffer would not risk this, especially because many of his men were inexperienced or new recruits, and this would be their first battle. He understood that they would not fare well in a surprise attack mid-stream.

[ ![Confederate General Felix Zollicoffer](https://www.worldhistory.org/img/r/p/500x600/22123.jpeg?v=1788965954-1789953082) Confederate General Felix Zollicoffer Unknown (Public Domain) ](https://www.worldhistory.org/image/22123/confederate-general-felix-zollicoffer/ "Confederate General Felix Zollicoffer")In December 1861, Union Brigadier General George H. Thomas was ordered to attack Crittenden's forces and set out from Lebanon on 31 December. Because of the rain, which turned the roads to mud, it took two and a half weeks to reach Logan's Crossroads on 17 January 1862, which was ten miles (16 km) to the south of Zollicoffer's position. He then sent word to Brigadier General Albin F. Schoepf at Somerset to join him with reinforcements. Between Thomas's position and Schoepf's ran Fishing Creek, which, like the Cumberland River, was overflowing and fast-moving. Thomas was uncertain whether Schoepf would be able to cross. Scholar Benson Bobrick comments:

> As he waited for Schoepf to come, \[Thomas\] took diligent precautions to avoid being taken by surprise. He knew (as few others seemed to) that a surprise attack was especially hard for untried troops to bear; so, on the night of the 18th, he threw out pickets and cavalry vedettes in a wide arc, two miles to his front.
> His picket system was more sophisticated than any yet tried. "The usual method," writes one historian, "was to string out hundreds of pickets at every conceivable bypath, bridge, clump of trees, and wrinkle in the terrain." Thus dispersed, these troops could be scooped up before they could sound the alarm by an enemy advancing in force.
> Thomas, on the other hand, in addition to infantry pickets, "had strong patrols of cavalry out on the roads, able to fight a delaying action dismounted, then move back to prepared defenses" under the covering fire of their lines. 
> (94-95)

Earlier, Crittenden had received word of Zollicoffer's defensive position, which placed the river at his back and would serve as an obstacle to an orderly retreat, should one be necessary, and had arrived at the main encampment of Beech Grove to oversee operations. Concerned that the camp was in a vulnerable position and could easily be overrun by a Union advance, Crittenden ordered Zollicoffer to attack Thomas's position at Logan's Crossroads at dawn on 19 January.

### Battle of Mill Springs

Zollicoffer hoped to take Thomas by surprise and began his march toward Logan's Crossroads a little before midnight on 18 January under a heavy rain. The roads became nearly knee-deep in mud, slowing their advance and eliminating any chance of surprising the enemy.

[ ![Map of the American Civil War, 1861-1865](https://www.worldhistory.org/img/r/p/750x750/21119.png?v=1783225337-1759291607) Map of the American Civil War, 1861-1865 Simeon Netchev (CC BY-NC-ND) ](https://www.worldhistory.org/image/21119/map-of-the-american-civil-war-1861-1865/ "Map of the American Civil War, 1861-1865")Shortly after dawn on the 19th, Zollicoffer launched his attack, leading from the front, and pushed back the Union companies of the 10th Indiana Infantry and 1st Kentucky Cavalry. The Confederates quickly understood, however, that they had a serious problem: many of the men were carrying flintlock muskets, and the falling rain made these unreliable because it dampened the priming powder, preventing the flint from making the necessary spark, causing a misfire.

As Zollicoffer's forces struggled with their weapons while still advancing, Thomas, who had carefully planned the battle, was maneuvering his own. Bobrick writes:

> In just ten minutes, \[Thomas\] had his men on the move. One regiment was ordered forward to the right. When Rebel cavalry tried to outflank it, another was advanced and spread out. Before long, the fighting covered a mile of broken ground. Sight lines were obscured by tangled brush, fallen logs, and fields of corn, which made the artillery hard to use.
> But as Thomas rode onto the field, he aligned the men as they came up. Soon, the Federals had seized both sides of Mill Springs Road, reoccupied some ground a forward regiment had lost, and were moving through the woods toward a hill the Rebels held. 
> (95-96)

The morning was dark and thick with fog, obscuring visibility, and Zollicoffer became concerned that his men might be firing on friendly troops. As at the [First Battle of Bull Run (First Manassas)](https://www.worldhistory.org/First_Battle_of_Bull_Run_(First_Manassas)/) in July 1861 and the [Battle of Wilson's Creek](https://www.worldhistory.org/Battle_of_Wilson's_Creek/) in August of that year, uniform colors had not yet been standardized. Many Confederate regiments at this time still wore the Union blue, and many Union companies still wore gray.

**[Death](https://www.worldhistory.org/disambiguation/Death/) of Zollicoffer**

Across the field, through the fog and smoke of battle, Zollicoffer, who was nearsighted, mistook the Union 4th Kentucky Infantry for Confederates in blue and rode out to reconnoiter. He was wearing the white raincoat that officers on both sides wore and, as he crossed toward enemy lines, was greeted by Union Colonel Speed S. Fry, who took him for a fellow Union officer, just as Zollicoffer thought Fry was a Confederate. Scholar Stuart W. Sanders describes what happened next:

> Squinting toward Fry's battle line, Zollicoffer told Fry, "We must not shoot our own men." Fry responded, "Of course not. I would not shoot our own men intentionally." Zollicoffer then pointed to his left, toward the 19th Tennessee. "Those are our men," he said.
> Fry peered through the smoke in that direction. Since he could not see the regiment that Zollicoffer was pointing toward, Fry rode "some fifteen or twenty paces" to his right.
> Looking down the road, Fry saw a staff officer ride out from behind a tree. This time, there was no mistaking that the mounted soldier was the enemy. He fired a pistol at Fry and the bullet struck Fry's horse near the left hip. "I immediately drew my Colt revolver from the holster," Fry wrote, but the officer rode back behind the tree.
> Since Zollicoffer had ridden from that direction, Fry now knew that the mysterious officer before him was a Confederate. Additional sources note that the staff officer also yelled, "It's the enemy, general!"
> Fry immediately concluded that the officer in the white gum coat had duped him… "I raised my pistol and fired. His horse turned and he fell, within five feet of where he had stood, upon the right of the road and at right angles to it…" Fry yelled, "Shoot him!" and several Union soldiers let loose a volley. The forty-nine-year-old Zollicoffer was struck multiple times and fell dead in the road. 
> (77-78)

Some modern-day articles on the battle claim that, after Zollicoffer's death, the Confederate army fell back or began their full-scale retreat, but this is not so. Crittenden placed Colonel David Cummings in command of that sector of the battlefield, and Cummings told his staff officers to keep the news of Zollicoffer's death to themselves to prevent panic among the troops.

Far from retreating, the Confederate line advanced against the Union right flank. Many Confederate soldiers, frustrated with their useless firearms, smashed them against trees and rocks and advanced with the broken stocks as clubs in one hand and knives in the other. The Confederate advance clashed with the Union line in hand-to-hand fighting. Sanders notes:

> A member of the 10th Indiana recalled that, "we were so close to the enemy that we bayoneted them through the fence. The Mississippians were armed with great knives which they intended using on us, but our bayonets outreached their knives." 
> (85)

Crittenden then ordered in the forces under General William H. Carroll, including the 25th Tennessee, which had been held in reserve, to support the charge. By this time, the smoke of battle, combined with the lingering rain and fog, made visibility even worse than before. Sanders writes:

> The lack of visibility doomed the regiment. Crittenden reported that the 25th Tennessee quit firing because they believed that they were shooting at friendly units. Several Yankee volleys disabused them of that notion, and they were shoved from the field. 
> (87)

**Thomas's Counterattack**

Thomas had been reinforced by Schoepf around 11:00 and now ordered the 9th Ohio Infantry to advance under covering fire from the 2nd Minnesota Infantry. The 9th Ohio turned the Confederate left flank, breaking the line, and the Confederate troops fled from the field in a complete rout. As noted, many of the Confederate soldiers were inexperienced, lacked discipline, and so ignored officers' attempts to halt the disorderly retreat.

Thomas ordered his men to pursue, and the Union line advanced quickly, halting within a mile (1.6 km) of the Confederate encampment. Thomas then ordered the camp to be shelled until night fell, posting orders for an attack at dawn. Bobrick writes:

> During the night, however, the enemy fled across the river, and burned the boats they used to prevent a quick pursuit. The next morning, Thomas' men swept into the camp, scooping up all the abandoned provisions, 150 wagons, piles of small arms, entrenching tools, camp and garrison equipment, a thousand or more horses and mules, and an artillery train of twelve guns. Thomas sent Schoepf's brigade after the Rebels, but they had scattered far and wide. 
> (97)

In fact, the Confederate retreat continued from the Cumberland River to Chestnut Mound, Tennessee, approximately 57 miles (93 km), over the space of almost two weeks.

### Aftermath

The battle was a decisive victory that made George H. Thomas, the hero of the Union. Sanders notes:

> Extensive newspaper coverage of the fight – which proved to be the Union's first significant victory – propelled Thomas as Crittenden's tottering reputation collapsed. 
> (124)

Crittenden was accused of being drunk during the battle and mismanaging the operation. His army was disbanded and placed under other generals' command. He eventually resigned his commission and served without rank on the staff of other commanders.

Thomas Mathew Brady (Public Domain) ](https://www.worldhistory.org/image/21169/george-h-thomas/ "George H. Thomas")Thomas, on the other hand, continued on through the war, contributing significantly to many pivotal battles in the Western theater and winning the [Battle of Nashville](https://www.worldhistory.org/article/2816/battle-of-nashville/) (15-16 December 1864), which destroyed the Confederate Army of the Tennessee under [John Bell Hood](https://www.worldhistory.org/John_Bell_Hood/).

Zollicoffer's body, though initially stripped by soldiers for souvenirs, was treated respectfully by Union officers, embalmed, and sent back to Tennessee where it was interred in the Old City Cemetery in Nashville.

### Conclusion

The Battle of Mill Springs was one of the most significant battles of the American Civil War, eclipsed in the modern day only because so many others, receiving far greater attention and tallying more casualties, would follow it. Casualties at Mill Springs were light:

- Union killed: 39. Wounded: 207
- Confederate killed: 125. Wounded or missing: 404

Sanders notes:

> The Battle of Mill Springs knocked the bloom off the rose. It was a small battle of great consequence. With the events that followed, Americans realized that the Civil War would be an arduous struggle.
> As Eastham Tarrant of the 1st Kentucky Cavalry wrote, the battle "was one of the most brilliant victories to the Union cause, and one of the most important in its results that happened during the war. It was its first great victory. It revived the drooping spirits of the loyalists throughout the United States and spread consternation in the ranks of the heretofore audacious foe." 
> (125)

As noted, the only reason the battle is not better known is that Grant's victories at Fort Henry and Fort Donelson, coming so soon after, eclipsed it.
