The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting the Distinguished Service Cross to Private First Class Walter Havelosk Keene (ASN: 1204453), United States Army, for extraordinary heroism in action while serving with Company F, 105th Infantry Regiment, 27th Division, American Expeditionary Forces, at Arbre Guernon, France, 17 October 1918. During the advance of his company into the town, Private Keene, with utter disregard of his own personal danger, pursued several of the enemy into a house, and, single-handed, captured ten of them as they were in the act of setting up a machine-gun. On the following morning, 18 October 1918, near the town of Mazinghein, when the advance of the battalion had been temporarily halted by heavy enemy fire, Private Keene voluntarily carried a message for reinforcements to battalion headquarters through intense shell and machine-gun fire and returned with the necessary reinforcements, thereby enabling the battalion to continue its advance.
