“The Storks” (by memory officially called GC 12) was formed in November 1916 of 4 Escadrilles - with then N103 (later Spa 103) being part of it.
During the war 103 was credited with 108 aircraft victories plus a couple of ballons. Certainly a respectable number but of that 108 total René Fonck was responsible for 73 of them!

Whatever the personality quirks historically assigned to him (and my favorite was a quote from his reported closest friend) the man was a hell of a pilot.
