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 Major (Medical Corps) Horatio N. Jackson, United States Army, for extraordinary heroism in action while serving with 313th Infantry Regiment (Attached), 79th Division, American Expeditionary Forces, near Montfaucon, France, September 26 – 29, 1918. Constantly working in the face of heavy machine-gun and shell fire, Major Jackson was most devoted in his attention to the wounded, always present in the line of advance, directing the administering of first aid, and guiding the work of Utter bearers. He remained on duty until severely wounded by high-explosive shells, when he was obliged to evacuate.
