Whilst we were in conference, reports came in from General Willcox, who had been left in command of the Ninth Corps at Strawberry Plains, that the enemy were pressing him rather vigorously. Word came also from General Spears that hostile infantry and cavalry had appeared in large force at Blain's Cross-roads. Sturgis also reported from the direction of Sevierville that the whole rebel army had gone to Strawberry Plains. [Footnote: _Id_., pp. 163, 174.] Toward evening of the 22d our troops had come within some five or six miles of Knoxville, but the enemy showed so strong a disposition to attack that Foster ordered me to return to the front, take command of both corps (Ninth and Twenty-third) and of the cavalry with them, and check the Confederates, as there was some danger that our troops would change the concerted movement into a precipitate retreat. General Parke was suffering in health from recent exposure and remained in Knoxville. Galloping out from the town, I reached the troops a little before dark, halted them, and by a personal reconnoissance satisfied myself that only cavalry were before us. Our men had passed some wooded hills which were important to cover our position and give a starting-point for an aggressive movement on our part. Reversing their movement, I reoccupied these hills, brusquely driving back the enemy's advance-guard and checking their main body. It was now dark, and putting our forces in line of battle ready for an advance at daybreak, they were allowed to bivouac for the night, whilst I rode rapidly back to Knoxville, in accordance with my arrangement with General Foster to report to him in person the particulars of the situation. He approved my suggestion that I should advance the whole line in the morning and settle the question what force was before us. The wagons had come into the town, and my headquarters with them; so taking each of us a blanket, myself and the two staff officers who had accompanied me (Colonel Sterling and my brother) rode back again at midnight to the front, and rested till daybreak on the rough floor of a log cabin. The line then was advanced, but the enemy had taken the hint from the preparations of the evening and had decamped. [Footnote: Official Records, vol. xxxii. pt. ii. p. 184.] Detachments went in pursuit some eight miles, but the Confederates had definitely withdrawn, and we obtained conclusive proof that only their cavalry had followed us across the Holston River. The interrupted movement toward Knoxville was resumed, but it required me to remain another night in roughest bivouac, and another day without food, except as a mouthful could be found at hazard. I had begun the Dandridge movement with a cold which threatened pneumonia, but had grown steadily better through all the exposure, finding, as often happened to me in the course of the war, that the physical and mental stimulus of active campaigning even in the worst of weather was tonic and health-giving.
