On November 24, 1863, Cobham's Brigade of Geary's Division in Slocum's Corps, under Colonel George A. Cogham, Jr., included the 29th Pennsylvania under Colonel William Rickards, Jr., the 109th Pennsylvania under Captain Frederick L. Gimber, and the 111th Pennsylvania under Colonel Thomas M. Walker. The 29th and 111th Pennsylvania regiments, with the 109th left as picket and camp guard, marched at the head of General Geary's column from Wauhatchie soon after daylight and, concealed by fog, crossed Lookout Creek at 8 A.M. before moving by the flank up the western slope of Lookout until the right reached the foot of the palisades. Ireland's Brigade was on the left, and six regiments of Whitaker's Brigade of Cruft's Division followed as a second line. After a march of a mile and a quarter toward the north point of the mountain, the line struck the left flank and rear of General Walthall's skirmish line and later his main line, which, also attacked in front, was forced from position and pushed across the northern slope of the mountain to a point about 400 yards east of Cravens House, where the Confederate forces rallied and held their ground. Cobham, supported by Whitaker, fought on the front line with his right at the highest point under the palisades until relieved at 9 P.M. by troops from Grose's Brigade. Its strength in action was 36 officers and 538 men.
