L. Smith's division in the lead on the left, J. E. Smith's as the centre, and Ewing's on the right, with the front of each preceded by swarms of skirmishers. The northern end of the Ridge extends from the railroad tunnel under it for about a mile to the Chickamauga nearly north and south, and forms with that stream and the Tennessee three sides of a square, as it were. The ground enclosed within them is mostly level and consisted at the time of a succession of cleared fields through which the troops made the intervening distance of one and a half miles without much difficulty, although a drizzling rain was coming down. No resistance was met, and, at half-past three, the heights were attained by our skirmishers and soon after occupied in force. Here the Commanding General found that he had been in error in assuming that Missionary Ridge was a continuous, unbroken range. He discovered that his troops had gained only a fore-ridge, so to speak, about a third of a mile to the northwest of and separated from the main ridge by a little valley, and we were still half a mile north of the “Tunnel Hill,” our real aim.
Three brigades, one from each division, were pushed up the fore-ridge. Brigadier-General Lightburn, commanding the one to the left, perceiving that the main ridge had not been reached, of his own accord ordered one of his regiments to occupy the point on it directly in front of him, which it did successfully. Half an hour later, the enemy moved over the valley against our left flank. There was then sharp firing of small arms and artillery for a time, and General Lightburn's advanced troops had to be reinforced by three other regiments. Towards dark, the rebels withdrew, leaving us in our positions, which General Sherman then considered so important that he ordered them fortified during the night. Our casualties were small, but included Brigadier-General Giles A. Smith, a very efficient brigade commander, who received a severe wound. The corps bivouacked in several lines for the night. M. L. Smith's division formed the left; G. A. Smith's brigade
