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 Henry L. Signor (ASN: 10401), United States Army, for extraordinary heroism in action while serving with Section No. 647, Ambulance Service, American Expeditionary Forces, near Sommerance, France, 11 October 1918. Following the advance of the Infantry, Private Signor caused his car to be lifted across a mine crater by some infantrymen, and proceeding for three kilometers down a road heavily bombarded with gas and high-explosive shells he evacuated wounded from a culvert only 400 yards from enemy outposts. On the return trip his car was struck by splinters from an exploding shell which pierced the clothing of his aide and caused fresh wounds to one of his patients. After transferring his wounded across the crater to another car, he succeeded in driving it over a road almost destroyed by shell fire to a newly established dressing station in Sommerance. He continued to operate his car for 12 hours until he was relieved, having at all times displayed unhesitating courage and devotion to duty.
