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 First Lieutenant (Infantry) Cylburn O. Mattfeldt, United States Army, for extraordinary heroism in action while serving with 9th Infantry Regiment, 2d Division, American Expeditionary Forces, near Jaulny, France, 13 September 1918. In plain view of the enemy Lieutenant Mattfeldt rode across a field to a friendly battery, whose barrage was falling on the American trenches, and stopped its fire, thereby permitting a reestablishment of the front line and saving many lives.
