Montigny mitrailleuse
The Montigny mitrailleuse was an early type of crank-operated machine-gun developed by the Belgian gun works of Joseph Montigny between 1859 and 1870. It was an improved version of the "Mitrailleuse", () invented by Belgian Captain Fafschamps in 1851 which was a fixed 50-barrelled volley gun.
Grenade
Marten Hale, better known for patenting the Hales rifle grenade, developed a modern hand grenade in 1906 but was unsuccessful in persuading the British Army to adopt the weapon until 1913. Hale's chief competitor was Nils Waltersen Aasen, who invented his design in 1906 in Norway, receiving a patent for it in England. He began his experiments with developing a grenade while serving as a sergeant in the Oscarsborg Fortress. Aasen formed the "Aasenske Granatkompani" in Denmark, which before the First World War produced and exported hand grenades in large numbers across Europe. He had success in marketing his weapon to the French and was appointed as a Knight of the French Legion in 1916 for the invention.
