Colonel
Charles Sweeny, an American pilot who had served in
World War I, proposed organizing a squadron of American pilots to assist the French in Morocco, to French Prime Minister
Paul Painlevé, who "warmly welcomed the Colonel’s request." Seeking "volunteers," Sweeny sent a telegram to a number of World War I veterans in the US in June 1925. By July, he had 17 volunteers, 12 of whom were pilots, including
Paul Ayres Rockwell, had served France in World War I. The American volunteers were inducted into the
French Foreign Legion in July, and their squadron was named
Escadrille Cherifienne, 19th Squadron of the Moroccan Aviation Regiment. It was legally attached to the Sultan's Guard, and not to French forces. In a telegram to the French
résident général in Morocco
Hubert Lyautey, the Prime Minister and Minister of War of France
Paul Painlevé said: "This American expression of solidarity seems particularly interesting at the moment and capable of bringing a share of American propaganda to our cause, strengthening American sentiment against the aggression of
Abd el-Krim." == Operations ==
