The Escadrille Americaine is officially authorized to organize a group of American volunteers to form squadron N124 within the French Air Service. The Escadrille is formally activated on April 17. The numbers of American volunteers are so great that only some of them can be accommodated in the original Escadrille, but are assigned and fly with over 100 different French squadrons. Later, the name is changed to the Lafayette Escadrille. All the Americans who passed through the system are members of the “Lafayette Flying Corps,” but only some are members of the Lafayette Escadrille itself.
