 On November 1, 1864, the 21st, then in command of Colonel Bishop, was at Dalton, Ga., where it received orders to march to Kingston and join the 14th army corps, and on arriving there was assigned to the 2d brigade, 1st division, when it started for Atlanta, and on the march assisted in tearing up the railroad track and destroying everything in its rear, reaching that point on the 15th, and on the following day after the destruction of that place, moved with General Sherman's army towards Milledgeville, arriving there on the 22d, and then took up a line of march in the direction of Augusta, and on reaching within about forty miles of that point, turned directly south towards Savannah, and arrived at the works in front of that place on the 10th of December, and there relieved a part of the 20th army corps, which held a portion of the works on the south side of the canal, being the most exposed position on the whole line.There the men being obliged to stay in the trenches, without tents and lightly clad, few of them having blankets, suffered extremely from cold, and also from hunger, as their rations were short.The regiment continued in that position until the 15th, when it moved back north of the canal, and remained there until the evacuation of Savannah on the 21st, and then encamped about three-fourths of a mile from the city.
