Toussaint-Henry-Joseph Fafchamps
Joseph Montigny further improved the weapon, completing the transportable 37-barrels Montigny mitrailleuse (also known as the "Fafschamps-Montigny mitrailleuse") in 1863. From 1859, Joseph Montigny proposed his design to Napoleon III, which led to the development of the French Reffye mitrailleuse, designed by Jean-Baptiste Verchère de Reffye with the collaboration of Montigny, and which was adopted by the French Army in 1865. The invention of Fafschamps thus became the basis of the "mitrailleuse", which was used by the French in the Franco-Prussian War of 1870. Initially kept under wraps as a secret weapon, it became widely used in battle by French artillery during the Franco-Prussian War (1870–71).

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.
