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 (Air Service) Lewis Hyde Brereton (ASN: 0-3132), United States Army Air Service, for extraordinary heroism in action while serving with Corps Observation Wing, U.S. Army Air Service, A.E.F., over Thiaucourt, France, 12 September 1918. Major Brereton, together with an observer, voluntarily and pursuant to a request for special mission, left his airdrome, crossed the enemy lines over Lironville, and proceeded to Thiaucourt. In spite of poor visibility, which forced them to fly at a very low altitude, and in spite of intense and accurate anti-aircraft fire they maintained their flight along their course and obtained valuable information. Over Thiaucourt they were suddenly attacked by four enemy monoplane Fokkers. Maneuvering his machine so that is observer could obtain a good field of fire, he entered into combat. His observer’s guns becoming jammed, he withdrew until the jam was cleared, when he returned to the combat. His observer then becoming wounded, he coolly made a landing within friendly lines, although followed down by the enemy to within 25 meters of the ground. By this act he made himself an inspiration and example to all the members of his command.
