query: Who invented the mitrailleuse?
passage: Mitrailleuse
A mitrailleuse (French pronunciation:​[mitʁajøz]; from French mitraille, "grapeshot") is a type of volley gun with multiple barrels of rifle calibre that can fire either multiple rounds at once or several rounds in rapid succession. The earliest true mitrailleuse was invented in 1851 by Belgian Army captain Fafschamps, 10 years before the advent of the Gatling gun. It was followed by the Belgian Montigny mitrailleuse in 1863. Then the French 25 barrel "Canon à Balles", better known as the Reffye mitrailleuse, was adopted in great secrecy in 1866. It became the first rapid-firing weapon deployed as standard equipment by any army in a major conflict when it was used during the Franco-Prussian War of 1870–71. A steel block containing twenty-five 13mm (.51 calibre) centre-fire cartridges was locked against the breech before firing. With the rotation of a crank, the 25 rounds were discharged in rapid succession. The sustainable firing rate of the Reffye mitrailleuse was 100 rounds per minute. The maximum effective range of the Reffye mitrailleuse was about 2000 yards; a distance which placed their batteries beyond the reach of Prussian Dreyse needle rifle fire. Reffye mitrailleuses were deployed in six gun batteries and were manned by artillery personnel. They were not infantry support weapons, but rather a form of special artillery.

The Chassepot was named after its inventor, Antoine Alphonse Chassepot (1833–1905), who, from 1857 onwards, had constructed various experimental forms of breechloader, and the rifle became the French service weapon in 1866. In the following year it made its first appearance on the battlefield at Mentana on 3 November 1867, where it inflicted severe losses upon Giuseppe Garibaldi's troops. It was reported at the French Parliament that ""Les Chassepots ont fait merveille!"", or loosely translated: "The Chassepots have done wonderfully!" The undisguised truth is that the heavy cylindrical lead bullets fired at high velocity by the Chassepot rifle inflicted wounds that were even worse than those of the earlier Minié rifle.
