Fashoda casualty count:
Military deaths: 7.586.000 million people.
Civilian deaths: 5.900.000 million people.
(Military deaths, 7.586.000 against OTL 9.911.000).
(Civilian deaths, 5.900.000 against OTL 7.700.000).
I am not counting military wounded, because I think is not that important. We lack Russian deaths, but we still have important parts of the war in Europe, like Scandinavia, Italy and the Mediterranean, Spain-Gibraltar, etc.
We will get the Russian Plague death count in the next year if I remember it.
It also could depends in how you define the casuality count, like, there are the victims of civil wars caused and during Fashoda (I am not counting them in this but they exist).
