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 Captain (Air Service) Frank Albert Llewellyn, United States Army Air Service, for extraordinary heroism in action while serving with 99th Aero Squadron, U.S. Army Air Service, A.E.F., east of St. Die, France, 17 August 1918. Captain Llewellyn, acting as pilot, and Lieutenant Roland Neel, acting as observer, carried on successful liaison with the infantry during the attack on Frapelle. They flew over the enemy lines at an altitude of only 400 meters, firing on and disconcerting the enemy, and thereby giving courage and confidence to the American forces. Despite heavy fire from 15 anti-aircraft machine guns and several batteries of anti-aircraft artillery, they performed their work efficiently. Their aeroplane was struck by a number of machine-gun bullets, one of which cut the rudder and elevator control wires and caused the rudder to jam. The broken control wire was held and operated by Lieutenant Neel, under direction of Captain Llewellyn. Running the machine together in this manner, they continued their liaison work until the plane began to become unmanageable, when, in spite of its damaged condition, they brought it back to their airdrome.
