"Vallois, Robert Captain of Air Service, French Army Observer, 16th Pursuit Group, French Air Service Date of Action: September 12, 1918 Citation: The Distinguished Service Cross is presented to Robert Vallois, Captain of Air Service, French Army, for extraordinary heroism in action near Thiaucourt, France. Captain Vallois volunteered to fly with Major Lewis H. Brereton on an important reconnaissance mission. On account of poor visibility they were forced to fly at a very low altitude and were continually harassed by antiaircraft fire. Four enemy monoplanes (type Fokker) attacked them, and during the combat which followed Captain Vallois' gun jammed. After withdrawing for the purpose of clearing the jam they again returned to the fight, and, despite the fact that he had been painfully wounded in the face, Captain Vallois succeeded in dispersing three of the adversaries and fought off the other while his pilot made a landing.

"Ira Beaman Joralemon (1884 – 1975) was an American mining engineer, economic geologist, and mining company executive, who specialized in exploration and mining of copper ore deposits. Over a career spanning more than six decades, Joralemon was involved in the discovery and development of numerous major copper and gold deposits, many of which went on to become operational mines. In addition to his professional career within the minerals industry, he was also a popular science author and historian of the mining industry. [...] His work with the C&A Company was interrupted by World War I, during which Joralemon served with the United States Army Air Service between 1917 and 1919. For part of this time Major Joralemon was a member of General Billy Mitchell's staff, and was commended by Mitchell for his "wonderful work" during preparations for the Battle of Saint-Mihiel.[5] For his service to France the French government awarded him the distinction of Chevalier of the Legion d'Honneur in 1918." en.wikipedia.org/wiki/Ira_Joralemon
