When was the first mitrailleuse developed?
Mitrailleuse
After Napoleon III's abdication following the disastrous French defeat in the Battle of Sedan, French war powers fell into the hand of a republican government led by Léon Gambetta. He vigorously organized national defense and the continued manufacture of war equipment. Most of the conventional weapon manufacturing was located in provincial France, but some mitrailleuse repair and even construction continued inside Paris during the city's four-month siege.
