McCook's division was advanced about six miles to Munfordville on Green River, and General George H. Thomas' division was ordered to Liberty, where he would be nearer the main army, and later his headquarters were at Lebanon, and his division, consisting of four brigades and some unattached cavalry and three batteries of artillery, was posted there and at Somerset and London.(11) December 17th, four companies of the 32d Indiana (German), under Lieutenant-Colonel Von Treba, from McCook's command, on outpost duty at Rowlett's Station, south of Green River, were assailed by two infantry regiments, one of cavalry--Texas Rangers--and a battery of artillery. The gallantry and superiority of the drill of these companies enabled them to drive back the large force and hold their position until other companies of the regiment arrived, when the enemy was forced to a hasty retreat, both sides suffering considerable loss. Colonel B. F. Terry (12) of the Texas Rangers forced his men to repeatedly charge into the ranks of the infantry. In a last charge he was killed, and the attacking force retired in disorder. Great credit was due to Colonel Treba and his small command for their conduct. Colonel James A. Garfield was placed in command of the field forces in the Big Sandy country, Eastern Kentucky, and General Humphrey Marshall, of Kentucky, who made pretensions to military skill, confronted him, each with a force, somewhat scattered, of about five thousand men. Inexperienced as Garfield then was in war, he, in mid-winter, in a rough country, with desperate roads and with a poorly equipped command, with no artillery, displayed much energy and ability in pushing his forces upon the enemy at Prestonburg and Paintsville, Kentucky. There were skirmishes December 25, 1861, at Grider's Ferry on the Cumberland River, at Sacramento on the 28th, at Fishing Creek January 8, 1862, and a considerable engagement at Middle Creek, near Prestonburg, on the 10th, the result of which was to drive Marshall practically out of Kentucky, and to greatly demoralize his command and put him permanently in disgrace. Next in importance came the more considerable fight at Logan's Cross-Roads, on Fishing Creek, Kentucky, commonly called the battle of Mill Springs, fought January 19, 1862, General George H. Thomas commanding the Union forces, and General George B. Crittenden the Confederates. The Confederate troops occupied an intrenched camp at Beech Grove, on the north side of the Cumberland River, nearly opposite Mill Springs. General Thomas, with a portion of the Second and Third Brigades, Kenny's battery, and a battalion of Wolford's cavalry, reached Logan's Cross-Roads, about nine miles north of Beech Grove, on the 17th, and there halted to await the arrival of other troops before moving on Crittenden's position.
