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).
Cutlass
Cutlasses are famous for being used by pirates, although there is no reason to believe that Caribbean buccaneers invented them, as has sometimes been claimed. However, the subsequent use of cutlasses by pirates is well documented in contemporary sources, notably by the pirate crews of William Fly, William Kidd, and Stede Bonnet. French historian Alexandre Exquemelin reports the buccaneer François l'Ollonais using a cutlass as early as 1667. Pirates used these weapons for intimidation as much as for combat, often needing no more than to grip their hilts to induce a crew to surrender, or beating captives with the flat of the blade to force their compliance or responsiveness to interrogation.
