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.
