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 Lieutenant Colonel (Infantry) Charles Fullington Thompson, 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 Assistant Chief of Staff, G-2, of the 1st Army, Lieutenant Colonel Thompson aided in its organization by his skill and sound judgment, participating in the preliminary preparations and operations at the St. Mihiel salient. The successes achieved by his section are largely due to his high military attainments, his great energy, and painstaking devotion to duty. He served with equal ability as G-2 of the 2d Army in September 1918, at all times showing great skill and accomplishing results of exceptional value.
