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 Captain (Field Artillery) Charles B. Duncan, United States Army, for extraordinary heroism in action while serving with 77th Field Artillery, 4th Division, American Expeditionary Forces, near Bois-de-Septsarges, France, 29 September 1918. When an enemy shell landed in the ammunition dump of his battery, Captain Duncan jumped in among the burning shells and succeeded in getting the fuses away and extinguishing the fire. Later he was mortally wounded by enemy shell fire.
