Our men drove the troops in front of the lower line of rifle-pits so rapidly, and followed them so closely, that rebel and Union troops went over the first line of works almost at the same time. Many rebels were captured and sent to the rear under the fire of their own friends higher up the hill. Those that were not captured retreated, and were pursued. The retreating hordes being between friends and pursuers caused the enemy to fire high to avoid killing their own men. In fact, on that occasion the Union soldier nearest the enemy was in the safest position. Without awaiting further orders or stopping to reform, on our troops went to the second line of works; over that and on for the crest--thus effectually carrying out my orders of the 18th for the battle and of the 24th (*17) for this charge.
I watched their progress with intense interest. The fire along the rebel line was terrific. Cannon and musket balls filled the air: but the damage done was in small proportion to the ammunition expended. The pursuit continued until the crest was reached, and soon our men were seen climbing over the Confederate barriers at different points in front of both Sheridan's and Wood's divisions. The retreat of the enemy along most of his line was precipitate and the panic so great that Bragg and his officers lost all control over their men. Many were captured, and thousands threw away their arms in their flight.
Sheridan pushed forward until he reached the Chickamauga River at a point above where the enemy crossed. He met some resistance from troops occupying a second hill in rear of Missionary Ridge, probably to cover the retreat of the main body and of the artillery and trains. It was now getting dark, but Sheridan, without halting on that account pushed his men forward up this second hill slowly and without attracting the attention of the men placed to defend it, while he detached to the right and left to surround the position. The enemy discovered the movement before these dispositions were complete, and beat a hasty retreat, leaving artillery, wagon trains, and many prisoners in our hands. To Sheridan's prompt movement the Army of the Cumberland, and the nation, are indebted for the bulk of the capture of prisoners, artillery, and small-arms that day.
Except for his prompt pursuit, so much in this way would not have been accomplished.
While the advance up Mission Ridge was going forward, General Thomas with staff, General Gordon Granger, commander of the corps making the assault, and myself and staff occupied Orchard Knob, from which the entire field could be observed. The moment the troops were seen going over the last line of rebel defences, I ordered Granger to join his command, and mounting my horse I rode to the front. General Thomas left about the same time.
Sheridan on the extreme right was already in pursuit of the enemy east of the ridge. Wood, who commanded the division to the left of Sheridan, accompanied his men on horseback in the charge, but did not join Sheridan in the pursuit. To the left, in Baird's front where Bragg's troops had massed against Sherman, the resistance was more stubborn and the contest lasted longer. I ordered Granger to follow the enemy with Wood's division, but he was so much excited, and kept up such a roar of musketry in the direction the enemy had taken, that by the time I could stop the firing the enemy had got well out of the way. The enemy confronting Sherman, now seeing everything to their left giving way, fled also. Sherman, however, was not aware of the extent of our success until after nightfall, when he received orders to pursue at daylight in the morning.
As soon as Sherman discovered that the enemy had left his front he directed his reserves, Davis's division of the Army of the Cumberland, to push over the pontoon-bridge at the mouth of the Chickamauga, and to move forward to Chickamauga Station. He ordered Howard to move up the stream some two miles to where there was an old bridge, repair it during the night, and follow Davis at four o'clock in the morning. Morgan L. Smith was ordered to reconnoitre the tunnel to see if that was still held. Nothing was found there but dead bodies of men of both armies. The rest of Sherman's command was directed to follow Howard at daylight in the morning to get on to the railroad towards Graysville.
Hooker, as stated, was detained at Chattanooga Creek by the destruction of the bridge at that point. He got his troops over, with the exception of the artillery, by fording the stream at a little after three o'clock. Leaving his artillery to follow when the bridge should be reconstructed, he pushed on with the remainder of his command. At Rossville he came upon the flank of a division of the enemy, which soon commenced a retreat along the ridge. This threw them on Palmer. They could make but little resistance in the position they were caught in, and as many of them as could do so escaped. Many, however, were captured. Hooker's position during the night of the 25th was near Rossville, extending east of the ridge. Palmer was on his left, on the road to Graysville.
During the night I telegraphed to Willcox that Bragg had been defeated, and that immediate relief would be sent to Burnside if he could hold out; to Halleck I sent an announcement of our victory, and informed him that forces would be sent up the valley to relieve Burnside.
