Recruited by his fellow verteran Merian C. Cooper in 1919, he became one of the best pilots of the Polish 7th Air Escadrille, dubbed the Kościuszko Escadrille (the Kosciuszko Squadron, named for Polish national hero Tadeusz Kościuszko). He was promoted to colonel and he received Poland's highest military decoration: the Virtuti Militari,[year needed] besides being awarded the Cross of Valour four times.
- Olson and Cloud (2010) remark on his being named after Cedric Errol, Lord Fauntleroy, boy protagonist of the highly successful children's novel Little Lord Fauntleroy published in 1885/6. Lynne Olson, Stanley Cloud, For Your Freedom and Ours, Random House, 2010, 29f. "At a little sidewalk café in Paris, he [ Merian C. Cooper ] recruited his first volunteer, a tall, lean army major from Mississippi with the improbable name of Cedric Errol Fauntleroy. A friend of Cooper's, Fauntleroy had flown in France with Eddie Rickenbacker's famous "Hat in the Ring" squadron. He had grown up on a small plantation near Natchez, Mississippi, where his incorrigibly romantic mother had given him the first and middle names of the golden-haired protagonist of Little Lord Fauntleroy and read him poems by Byron and others celebrating the heroics of Tadeusz Kościuszko." His middle name is occasionally reported as Erald.
