The Chassepot was an early French single-shot catridge rifle from the mid 19th centuary. It's self contained paper catridges used an internal primer that was pierced by a long needle, hence the term 'needle-fire'. This rifle was standard issue during the Franco-Prussian war and proved well liked by both sides.
