On 30 September 1916 a French Farman F.40 bomber of Escadrille 384 was tasked with attacking the Bulgarian capital, Sofia. Two Bulgarian Fokker E.IIIs were positioned south of Sofia to intercept the intruder, while a flight of three armed Albatros C.III two-seat trainers covered the center of the city as backup. The bomber successfully dropped its bombs over Sofia while escaping anti-aircraft fire but, while departing, was attacked by the Bulgarian Fokkers, one piloted by Marko Parvanov, which brought the Farman down with a dead engine.
