The events of the day had indicated that Bragg's main object was to turn Rosecrans's left; it was therefore still deemed necessary that the army should continue its flank movement to the left, so orders came to draw my troops in toward the widow Glenn's house. By strengthening the skirmish line and shifting my brigades in succession from right to left until the point designated was reached, I was able to effect the withdrawal without much difficulty, calling in my skirmish line after the main force had retired.
My command having settled down for the night in this new line I rode to army headquarters, to learn if possible the expectations for the morrow and hear the result of the battle in General Thomas's front.
Nearly all the superior officers of the army were at headquarters, and it struck me that much depression prevailed, notwithstanding the fact that the enemy's attempts during the day to turn our left flank and also envelop our right had been unsuccessful. It was now positively known, through prisoners and otherwise, that Bragg had been reinforced to such an extent as to make him materially outnumber us, consequently there was much apprehension for the future.
The necessity of protecting our left was most apparent, and the next day the drifting in that direction was to be continued. This movement in the presence of the enemy, who at all points was actively seeking an opportunity to penetrate our line and interpose a column between its right and left, was most dangerous. But the necessity for shifting the army to the left was obvious, hence only the method by which it was undertaken is open to question. The move was made by the flank in the face of an exultant foe superior in numbers, and was a violation of a simple and fundamental military principle. Under such circumstauces columns naturally stretch out into attenuated lines, organizations become separated, and intervals occur, all of which we experienced; and had the orders for the movement been construed properly I doubt if it could have been executed without serious danger. Necessity knows no law, however, and when all the circumstances of this battle are fully considered it is possible that justification may be found for the manoeuvres by which the army was thus drifted to the left. We were in a bad strait unquestionably, and under such conditions possibly the exception had to be applied rather than the rule.
At daylight on the morning of the 20th a dense fog obscured everything; consequently both armies were passive so far as fighting was concerned. Rosecrans took advantage of the inaction to rearrange his right, and I was pulled back closer to the widow Glenn's house to a strong position, where I threw together some rails and logs as barricades, but I was disconnected from the troops on my left by a considerable interval. Here I awaited the approach of the enemy, but he did not disturb me, although about 9 o'clock in the forenoon he had opened on our extreme left with musketry fire and a heavy cannonade. Two hours later it was discovered by McCook that the interval between the main army and me was widening, and he ordered me to send Laiboldt's brigade to occupy a portion of the front that had been covered by Negley's division. Before getting this brigade into place, however, two small brigades of Davis's division occupied the ground, and I directed Laiboldt to form in column of regiments on the crest of a low ridge in rear of Carlin's brigade, so as to prevent Davis's right flank from being turned. The enemy was now feeling Davis strongly, and I was about sending for Lytle's and Bradley's brigades when I received an order to move these rapidly to the, extreme left of the army to the assistance of General Thomas. I rode hastily back toward their position, but in the meanwhile, they had been notified by direct orders from McCook, and were moving out at a double-quick toward the Lafayette road. By this time the enemy had assaulted Davis furiously in front and flank, and driven him from his line, and as the confused mass came back, McCook ordered Laiboldt to charge by deploying to the front. This he did through Davis's broken ranks, but failed to check the enemy's heavy lines, and finally Laiboldt's brigade broke also and fell to the rear. My remaining troops, headed by Lytle, were now passing along the rear of the ground where this disaster took place--in column on the road--en route to Thomas, and as the hundreds of fugitives rushed back, McCook directed me to throw in Lytle's and Bradley's brigades. This was hastily done, they being formed to the front under a terrible fire.
Scarcely were they aligned when the same horde of Confederates that had overwhelmed Davis and Laiboldt poured in upon them a deadly fire and shivered the two brigades to pieces. We succeeded in rallying them, however, and by a counter attack regained the ridge that Laiboldt had been driven from, where we captured the colors of the Twenty-fourth Alabama. We could not hold the ridge, though, and my troops were driven back with heavy loss, including General Lytle killed, past the widow Glenn's house, and till I managed to establish them in line of battle on a range of low hills behind the Dry Valley road.
During these occurrences General Rosecrans passed down the road behind my line, and sent word that he wished to see me, but affairs were too critical to admit of my going to him at once, and he rode on to Chattanooga. It is to be regretted that he did not wait till I could join him, for the delay would have permitted him to see that matters were not in quite such bad shape as he supposed; still, there is no disguising the fact that at this juncture his army was badly crippled.
