From 2019, privately published by a highly experienced USAF combat pilot whose memoir, War for the Hell of It, has been well received.
The First Fighter Pilot - Roland Garros
If there's another bio in English I've not found it.
Bibliography includes French and English sources including RG's childhood in Saigon, reluctant law school student, automobile salesman, and self-taught pilot who began his airshow career with 3 hours total time.
Not much on RG's 2nd and 3rd victories but a full chapter on his POW experience and some insight to his death in 1918.
