Walcutt then participated in the March to the Sea in November and December 1864. He again fought with distinction at the Battle of Griswoldville on November 22, and was again wounded. His brigade of about 1,500 men moved to support Union cavalry and held a defensive position at Duncan's Farm against repeated attacks by ill-trained Confederate Georgia Militia. Combined Union losses in the fight were less than 100, including Walcutt, while the Confederates lost about 51 killed, 472 wounded, and around 600 missing or captured. Walcutt was wounded early in the action, and command of the brigade fell to Col. Robert F. Catterson of the 97th Regiment Indiana Infantry. Sherman would again praise him in his report, and Maj. Gen. Oliver O. Howard said of him "there is not a braver or better officer." He was hit in his right leg by a shell fragment, and would be out of action for months.
