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 Sergeant Roy L. Keller (ASN: 2178408), United States Army, for extraordinary heroism in action while serving with Company B, 354th Infantry Regiment, 89th Division, American Expeditionary Forces, near Remonville, France, 1 November 1918. When his combat group was heavily fired upon, while crossing open exposed ground, by two machine-guns, Sergeant Keller charged the position from the flank, personally killing one gunner and making the capture of the other members of the crews possible. His action made possible the advance of his company.
