The son of Charles S. and Lydia Terry (Paige) Baylies, Frank Leaman Baylies joined the United States Ambulance Service in May 1916. After seeing action on the Western Front, Serbia and Macedonia, he was rejected by the American air service due to defective vision and enlisted in the French Air Service in May 1917. After earning a Pilot's Brevet he was assigned to Spa73 at Dunkirk in November 1917. A month later he joined the Storks Group as a pilot with Spa3. In early 1918 Baylies refused a commission with the United States Air Service, preferring to remain with the French. He was killed in action when his patrol encountered the Fokker Triplanes of Jasta 19. Initially buried at Rollet, Baylies' body was exhumed in 1927 and reburied in Paris.

In a letter to Baylies' mother, Major Edmund Gros, Air Service Signal Reserve Corps, wrote:
Your son met a glorious death. He was one of the shining lights of our Aviation. He was a soldier without fear and without reproach. You must apply to him the eloquent words spoken in the British Parliament with respect to aviators; you must not turn your mind to sorrow, you must turn it towards all the glory which your son has won and the name which he will leave behind him when the story of this great war is written. He has taken his place by the side of all those heroes who gladly gave up that which is most precious of all, their lives, for the greatest ideal, the happiness of the human race.1
