The battle of Chickamauga.
From this time to the battle of Chickamauga he was constantly engaged and rendered effective service, both in Middle and East Tennessee. In the battle of Chickamauga, his men, dismounted, fought with the infantry until the retreat began, when, mounting his men, he pursued to within three miles of Chattanooga. He captured a Federal officer in a tall tree that had been conveniently arranged for an observatory; mounting to his place, he could see the enemy retreating along the roads and in the town of Chattanooga in great confusion and chaos. He communicated these facts to headquarters, and urged an immediate advance of the Confederate army upon them. Had his example or his advice been followed, Sherman's march to the sea might never have been made.
