On the morning of the 21st the enemy failed to advance, and his inaction gave us the opportunity for getting the broken and disorganized army into shape. It took a large part of the day to accomplish this, and the chances of complete victory would have been greatly in Bragg's favor if he could have attacked us vigorously at this time. But he had been badly hurt in the two days' conflict, and his inactivity on the 21st showed that he too had to go through the process of reorganization. Indeed, his crippled condition began to show itself the preceding evening, and I have always thought that, had General Thomas held on and attacked the Confederate right and rear from where I made the junction with him on the Lafayette road, the field of Chickamauga would have been relinquished to us; but it was fated to be otherwise.

Rosecrans, McCook, and Crittenden passed out of the battle when they went back to Chattanooga, and their absence was discouraging to all aware of it. Doubtless this had much to do with Thomas's final withdrawal, thus leaving the field to the enemy, though at an immense cost in killed and wounded. The night of the 21st the army moved back from Rossville, and my division, as the rearguard of the Twentieth Corps, got within our lines at Chattanooga about 8 o'clock the morning of the 22d. Our unmolested retirement from Rossville lent additional force to the belief that the enemy had been badly injured, and further impressed me with the conviction that we might have held on. Indeed, the battle of Chickamauga was somewhat like that of Stone River, victory resting with the side that had the grit to defer longest its relinquishment of the field.

The manoeuvres by which Rosecrans had carried his army over the Cumberland Mountains, crossed the Tennessee River, and possessed himself of Chattanooga, merit the highest commendation up to the abandonment of this town by Bragg on the 8th of September; but I have always fancied that that evacuation made Rosecrans over-confident, and led him to think that he could force Bragg south as far as Rome. After the Union army passed the river and Chattanooga fell into our hands; we still kept pressing the enemy's communications, and the configuration of the country necessitated more or less isolation of the different corps. McCook's corps of three divisions had crossed two difficult ridges—Sand and Lookout mountains—to Alpine in Broomtown Valley with intentions against Summerville. Thomas's corps had marched by the way of Stevens's Gap toward Lafayette, which he expected to occupy. Crittenden had passed through Chattanooga, at first directing his march an Ringgold. Thus the corps of the army were not in conjunction, and between McCook and Thomas there intervened a positive and aggressive obstacle in the shape of Bragg's army concentrating and awaiting reinforcement at Lafayette. Under these circumstances Bragg could have taken the different corps in detail, and it is strange that he did not, even before receiving his reinforcements, turn on McCook in Broomtown Valley and destroy him.

Intelligence that Bragg would give battle began to come to us from various sources as early as the 10th of September, and on the 11th McCook found that he could not communicate with Thomas by the direct road through Broomtown Valley; but we did not begin closing in toward Chattanooga till the 13th, and even then the Twentieth Corps had before it the certainty of many delays that must necessarily result from the circuitous and difficult mountain roads which we would be obliged to follow. Had the different corps, beginning with McCook's, been drawn in toward Chattanooga between the 8th and 12th of September, the objective point of the campaign would have remained in our hands without the battle of Chickamauga, but, as has been seen, this was not done. McCook was almost constantly on the march day and night between the 13th and the 19th, ascending and descending mountains, his men worried and wearied, so that when they appeared on the battle-field, their fatigued condition operated greatly against their efficiency. This delay in concentration was also the original cause of the continuous shifting toward our left to the support of Thomas, by which manoeuvre Rosecrans endeavored to protect his communications with Chattanooga, and out of which grew the intervals that offered such tempting opportunities to Bragg. In addition to all this, much transpired on the field of battle tending to bring about disaster. There did not seem to be any well-defined plan of action in the fighting; and this led to much independence of judgment in construing orders among some of the subordinate generals. It also gave rise to much license in issuing orders: too many people were giving important directions, affecting the whole army, without authority from its head. In view, therefore, of all the errors that were committed from the time Chattanooga fell into our hands after our first crossing the Tennessee, it was fortunate that the Union defeat was not more complete, that it left in the enemy's possession not much more than the barren results arising from the simple holding of the ground on which the engagement was fought.

THE END
