The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pride in presenting the Distinguished Service Cross (Posthumously) to First Lieutenant (Medical Corps) Robert Harrison Murdoch, United States Army, for repeated acts of extraordinary heroism in action while serving with 47th Infantry Regiment (Attached), 4th Division, American Expeditionary Forces, at Sergy, France, 29 to 31 July 1918; and at St. Thibault, France, 6 to 12 August 1918. Accompanying his battalion in the attack on Sergy, Lieutenant Murdoch advanced for more than a mile under heavy shell fire, and as soon as the southern half of the town had been taken he established his dressing station, maintaining it during the three days of fighting under constant and severe bombardment. When his battalion went into action at St. Thibault this faithful officer again displayed heroic devotion to duty by working in his dressing station under the most trying conditions for six days while the town was bombarded with gas and high-explosive shells.
