The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting the Army Distinguished Service Medal to Colonel (Ordnance Corps) Charles Tillman Harris, Jr., United States Army, for exceptionally meritorious and distinguished services to the Government of the United States, in a duty of great responsibility during World War I, as Chief of the American Mission of Powder and Explosives Manufacture which visited England. Later, as Chief of the Powder and Explosive Section of the Engineering Division of the Office of the Chief of Ordnance, he applied foreign methods of manufacture to United States industry so successfully that not only were the needs of the United States fully met, but a considerable surplus of these materials was rendered available for the co-belligerents against Germany.
