The Battle of Mill Springs took place in Wayne and Pulaski Counties as part of a Confederate offensive campaign in eastern Kentucky. While considered a small battle in comparison to many in the Civil War, the battle at Mill Springs was the second largest in Kentucky. Only the Battle of Perryville had more bloodshed.
Although Brig. Gen. Felix K. Zollicoffer's main responsibility was to guard Cumberland Gap, in November he advanced west into Kentucky to strengthen control in the area around Somerset. He found a strong defensive position at Mill Springs and decided to make it his winter quarters. He fortified the area, especially both sides of the Cumberland River.
Brig. Gen. George Thomas received orders to drive the Confederates across the Cumberland River and break up Maj. Gen. George B. Crittenden's army. He left Lebanon and slowly marched through rain-soaked country, arriving at Logan's Crossroads on January 17, where he waited for Brig. Gen. A. Schoepf's troops from Somerset to join him.
Crittenden, Zollicoffer's superior, had arrived at Mill Springs and taken command of the Confederate troops. He knew that Thomas was in the vicinity and decided that his best defense was to attack the Federals. The Confederates attacked Thomas at Logan's Crossroads at dawn on January 19. Unbeknownst to the Confederates, some of Schoepf's troops had arrived and reinforced the Union force. Initially, the Confederate attack forced the first unit it hit to retire, but stiff resistance followed and Zollicoffer was killed by Col. Speed S. Fry.
The Confederates made another attack but were repulsed. Union counterattacks on the Confederate right and left were successful, forcing them from the field in a retreat that ended in Murfreesboro, Tennessee. The Battle of Mill Springs, along with Middle Creek, broke whatever Confederate strength there was in eastern Kentucky. Confederate fortunes did not rise again until summer when Gen. Braxton Bragg launched his offensive into Kentucky. Mill Springs was the larger of the 2 Union Kentucky victories in January 1862. With these victories, the Union army carried the war into Middle Tennessee in February.
