But it was right hard to keep Morgan out of Sumner county—he had a great affection for it. He persistently applied for permission to attack the force stationed at Hartsville, and it was at length granted him. He was allowed to select two regiments from the Kentucky infantry brigade, and to take also Cobb's battery, a very fine one, attached to that brigade. The "Kentucky brigade" was commanded by Colonel Roger W. Hanson, who had been only a short time before exchanged, with his gallant regiment, the Second Kentucky infantry, which had been captured at Donelson. One of the colonels of the brigade, was Thomas H. Hunt, a very superior officer, who, with his regiment, the Ninth Kentucky, one of the best in the Confederate service, had seen arduous and hazardous service at Shiloh, Corinth and Baton Rouge. Colonel Morgan asked that this officer (his uncle) should command the infantry regiments, which were to form part of his force for the expedition; and Colonel Hunt selected his own regiment and the Second Kentucky (infantry).
On the morning of the 7th of December, Colonel Morgan set out on this expedition. The cavalry force was placed under my command, and consisted of Gano's, Bennett's, Cluke's and Chenault's regiments, and Stoner's battalion—in all numbering about fifteen hundred men. Hanson's brigade was encamped at Baird's mill. Here the infantry detachment joined us, seven hundred strong; the full strength of neither regiment was taken. Quirk's "scouts" and other scouting parties were sent to reconnoiter in the direction of Hartsville, to watch the enemy at Castalian Springs, and the fords of the river, and to picket the Nashville and Lebanon pike. The "combined forces" left Baird's mill about 11 a.m., and passed through Lebanon about 2 p.m., taking the Lebanon and Hartsville pike. The snow lay upon the ground and the cold was intense.
The infantry had been promised that they should ride part of the way, and, accordingly, a few miles beyond Lebanon a portion of the cavalry gave up the horses to them. This, however, was an injudicious measure. The infantry had gotten their feet wet in trudging through the snow, and, after riding a short time, were nearly frozen and clamored to dismount. The cavalrymen had now gotten their feet saturated with moisture, and when they remounted, suffered greatly in their turn. There was some trouble, too, in returning the horses to the proper parties (as this last exchange was effected after dark), and the infantrymen damned the cavalry service with all the resources of a soldier's vocabulary.
The infantry and Cobb's battery reached the ferry where it was intended that they should cross, about ten o'clock at night, and were put across in two small leaky boats, a difficult and tedious job. When the cavalry reached the ford, where Colonel Morgan had directed me to cross, I found that the river had risen so much since the last reconnoisance that it was past fording at that point, and I had to seek a crossing further down. The ford (where I decided to cross) was so difficult to come at, that the operation of crossing was made very slow. The men could reach the river bank only by a narrow bridle path which admitted only one man at a time. They were then compelled to gather their horses and leap into the river, over the bluff about four feet high. Horse and man would generally be submerged by the plunge—a cold bath very unpleasant in such weather. The ascent on the other side was nearly as difficult. In a little while the passage of the horses rendered the approach to the river even more difficult. The ford was not often used, and the unbeaten path became cut up and muddy. It grew worse and worse. The cold (after the ducking in the river) affected the men horribly; those who got across first built fires, at which they partially warmed themselves while the others were crossing. Only fifteen, however, were frozen so stiff that they had to be left.
Finding, as the night wore on, that day would appear before all got across, and fearing that I would detain Colonel Morgan, I moved (with those already on the northern bank) about three o'clock, leaving a great part of my column still on the southern side of the river. I posted pickets to watch the roads by which they could be attacked, and instructed the officers to hurry on to Hartsville as soon as practicable. I had about five miles to march to rejoin Colonel Morgan, and found him at the point he had designated, some three miles from Hartsville. He decided not to wait for the remainder of the cavalry, fearing that information would be taken to Castalian Springs (where six thousand Federal troops were encamped), and he would be himself attacked. He, therefore, moved forward at once. Just at daylight the cavalry, who were marching in front, came upon a strong picket force, about half a mile from the encampment, who fired and retreated. We were thus prevented from surprising the enemy before they formed. Colonel Morgan did not, however, expect to do so, for he had no certain plan of capturing the pickets without giving the alarm.
Bennett's regiment was immediately sent around the encampment, and into the town of Hartsville. Colonel Morgan ordered me to form Cluke's and Chenault's regiments opposite the right flank of the line the enemy were establishing, and partially outflanking it. The enemy was encamped in wooded ground, slightly elevated above the surrounding fields. The left flank of the line they formed rested upon open ground near the river. Opposite their right flank and center was a large meadow, between which and the woods was a slight depression, which gradually deepened toward the southward, until from a valley it became a ravine, and when it approached the river was perhaps ten feet deep, and its banks were almost precipitous. Colonel Morgan had intended to let the infantry of his command form in this ravine and attack from it, but the enemy's line was established so near to it that this was not attempted.
When we came in sight of the enemy and saw them forming, it was at once plain that the force there was much stronger than it had been represented to be. Instead of fifteen hundred men, as Colonel Morgan had estimated it to be from the reports of his spies, it was more than twenty-five hundred strong. I said to him, "You have more work cut out for you, than you bargained for." "Yes," he answered, "you gentleman must whip and catch these fellows, and cross the river in two hours and a half, or we'll have six thousand more on our backs." Cluke's and Chenault's regiments after deducting horse-holders, numbered four hundred and fifty men, between them. I formed Cluke opposite the One Hundred and Fourth Ohio Infantry, eight hundred strong, and formed Chenault obtusely to Cluke (on the latter's left), with his (Chenault's) left flank inclining toward the enemy, and outflanking him. The infantry were shortly afterward formed opposite the center of the enemy—Cobb's battery confronted the enemy's left flank. Our entire force in the fight (Bennett having been sent to Hartsville to prevent the escape of the enemy in that direction) was twelve hundred and fifty men. I have neglected to state that Stoner's battalion had been sent, with the "Bull pups," down the Hartsville and Lebanon pike to take position opposite the enemy's encampment. Stoner was instructed to maneuver in sight of the enemy, and shell away at them briskly. Colonel Morgan knew that the little pieces could not reach the encampment, but he wished the enemy's attention attracted to that quarter.
Stoner succeeded so well that the two Parrot guns which the enemy had were engaged with him, when we took position, and we were spared the annoyance they could have inflicted while we were forming. As I have said we failed to surprise the Federal force in its camp—and the only advantage which our sudden appearance gave us, was the partial demoralization which is apt to assail all troops, when unexpectedly and promptly attacked. The enemy naturally thought that we were in overwhelming force, or that we would not have incurred such risks.
One good sign was, that, as we formed in sight of each other, our ringing shouts were answered by the feeblest of cheers. Cluke and Chenault having formed at a gallop, immediately dismounted their men and advanced. The enemy's line was about four hundred yards distant. A line of skirmishers occupied the hollow, posted behind a fence, whose fire did us some little damage. These two regiments had never been under fire before (with the exception of a slight skirmish which Cluke's had witnessed in Kentucky) and I was not at first certain that they would drive their part of the line. But they moved on with perfect steadiness, halting (after having advanced about a hundred yards) to discharge a volley which dislodged the skirmishers, and then, after reloading, pressed on at a swift run. The enemy fired by rank, each volley passing over our heads, for the men had reached the hollow. No time was given them to reload. When within sixty yards our fellows opened, Cluke pressing right upon the front, and Chenault having swept so far round, and then closed in, that the two regiments were firing almost into each other's faces.
The open cavalry formation not only enabled us with a smaller force, to cover the entire front of the enemy opposed to us, but while exposing us to less loss, made our fire more deadly. The One Hundred and Fourth Ohio backed about twenty steps, the men striving to reload their guns, and it then broke and ran in perfect disorder. Cluke and Chenault moved on, swinging around to the right, until they were formed at right angles to the original direction of their line, and the force confronting them was lapped back upon the rest of the enemy's line. This lasted about twenty minutes. By that time Colonel Hunt had formed his infantry, and he sent them in, in echelon, the Second Kentucky in advance. Cobb's battery had not been idle, and had gotten one caisson blown up by a shell from one of the enemy's Parrots.
