the corps nomenclature established by General Buell was dropped, the grand divisions into which he had organized the army at Louisville were maintained, and, in fact, the conditions established then remained practically unaltered, with the exception of the interchange of some brigades, the transfer of a few general officers from one wing or division to another, and the substitution of General Thomas for Gilbert as a corps commander.  The army was thus compact and cohesive, undisturbed by discord and unembarrassed by jealousies of any moment; and it may be said that under a commander who, we believed, had the energy and skill necessary to direct us to success, a national confidence in our invincibility made us all keen for a test of strength with the Confederates.  We had not long to wait.

Early on the morning of December 26, 1862, in a heavy rain, the army marched, the movement being directed on Murfreesboro’, where the enemy had made some preparation to go into winter-quarters, and to hold which town it was hoped he would accept battle.  General Thomas moved by the Franklin and Wilson pikes, General Crittenden by the Murfreesboro’ pike, through Lavergne, and General McCook by the Nolensville pike—­Davis’s division in advance.  As McCook’s command neared Nolensville, I received a message from Davis informing me that the Confederates were in considerable force, posted on a range of hills in his front, and requesting me to support him in an attack he was about to make.  When the head of my column arrived at Nolensville I began massing my troops on the right of the road, and by the time this formation was nearly completed Davis advanced, but not meeting with sufficient resistance to demand active assistance from me, he with his own command carried the hills, capturing one piece of artillery.  This position of the Confederates was a strong one, defending Knob’s Gap, through which the Nolensville and Triune pike passed.  On the 27th Johnson’s division, followed by mine, advanced to Triune, and engaged in a severe skirmish near that place, but my troops were not called into action, the stand made by the enemy being only for the purpose of gaining time to draw in his outlying troops, which done, he retired toward Murfreesboro’.  I remained inactive at Triune during the 28th, but early on the 29th moved out by the Bole Jack road to the support of, Davis in his advance to Stewart’s Creek, and encamped at Wilkinson’s crossroads, from which point to Murfreesboro’, distant about six miles, there was a good turnpike.  The enemy had sullenly resisted the progress of Crittenden and McCook throughout the preceding three days, and as it was thought probable that he might offer battle at Stewart’s Creek, Thomas, in pursuance of his original instructions looking to just such a contingency, had now fallen into the centre by way of the Nolensville crossroads.
