"For exceptionally meritorious and distinguished service in a position of great responsibility to the Government of the United States, during World War I. Captain De Lagrange's broad knowledge of the conditions of modern warfare, gained through creditable service at the front, coupled with his loyalty and friendship for the United States and the American Army, fitted him admirably for his important service as a member of the French Mission at Washington. Later, upon his return to France, as Chief of the Aeronautical Section of the French Mission at Tours, he assisted materially in the establishment of schools and training systems for our Air Service, thereby rendering services of the utmost value to the American Expeditionary Forces."
