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). ==See also==
