Distinguished Service Cross citation "Alfred D. Barksdale, captain, 116th Infantry. For repeated acts of extraordinary heroism in action near Samogneux, France, October 8, 1918; near Molleville, France, October 12; and in the Bois de la Grand Montagne, France, October 15, 1918. Commanding a support company during the attack of October 8, Capt. Barksdale discovered that his battalion had advanced ahead of the unit on the right flank, and was suffering heavy losses from machine gun fire. Without orders he attacked and captured the guns, taking many prisoners. On October 12 he worked for over an hour, exposed to a terrific bombardment, binding the wounds of his men. On October 15 he advanced alone in a thick wood and, with the aid of his pistol, put out of action a destructive machine gun which was pouring such a deadly fire his men could not raise their heads."
University of Virginia presentation At the centennial ceremonies for the
University of Virginia, Captain Barksdale on behalf of the alumni presented the university with a plaque listing the names of 80 graduates killed in World War I.
Virginia state senator and judge Barksdale returned to his private legal practice in Lynchburg from 1922 to 1938. Aligned with the
Byrd Organization, and following his father's career path, he sat on the Democratic State Central Committee. His successor was Samuel Cook Goggin, the long-time clerk of the Bedford County court. A decade later, during the
Great Depression, the Virginia General Assembly elected Barksdale as Judge of the Virginia Circuit Court for the Sixth Judicial Circuit, and he served from 1938 to 1940. ==Personal life==
