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 Aspirant Lucien Diot, French Air service, for extraordinary heroism in action while serving with 219th Escadrille, French Air Service, in the region of St. Mihiel, France, 12 September 1918. Aspirant Diot, while flying at an extremely low altitude, had his wireless set destroyed by enemy fire. Rather than return to his field, and in spite of being eight kilometers beyond the lines, he descended to less than one hundred meters altitude and attacked an enemy convoy, routing it in confusion. This act was accomplished in spite of being under terrific machine-gun fire and heavy anti-aircraft artillery fire from the ground, his plane being shattered with bullets.
