Hello All,
I'm interested in victories scored by airmen flying cannon-armed aircraft (except Spad XII, about which I know enough

) during WW1.
Were the French the only one to score such victories in their Voisins, Breguets and maybe other cannon-armed aircraft? What about Russians, British, Italians, Americans, Germans and Austro-Hungarians?
How many (more or less) victories were scored by cannon-armed aircraft and is it often possible to state whether they were scored with cannons or machine guns? Any examples of such victories?
Thanks in advance for any replies

Albert
