ドライゼ銃
The Chassepot was named after its inventor, Antoine Alphonse Chassepot (1833–1905), who, from the mid-1850s onwards, had constructed various experimental forms of breech loaders. The first two models of the Chassepot still used percussion cap ignition. The third model, using a similar system to the Prussian Dreyse needle gun, became the French service weapon on 30 August 1866. In the following year it made its first appearance at the Battle of 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!", ("The Chassepots have done wonderfully!") The heavy cylindrical lead bullets fired at high velocity by the Chassepot rifle inflicted wounds that were even worse than those of the Minié rifle. By 1868, the entire French active army had been re-armed with the Chassepot.
