Editing Bayonet (section)

===Sword bayonets===
The 18th century introduced the concept of the [[sword bayonet]], a long-bladed weapon with a single- or double-edged blade that could also be used as a [[Classification of swords|shortsword]]. Its initial purpose was to ensure that riflemen could form an [[infantry square]] properly to fend off cavalry attacks when in ranks with musketmen, whose weapons were longer. A prime early example of a sword bayonet-fitted rifle is the Pattern 1800 Infantry Rifle, later known as the "[[Baker Rifle]]". Sword bayonets were used by German Jagers in the 18th century. The hilt usually had [[quillons]] modified to accommodate the [[gun barrel]] and a [[hilt]] mechanism that enabled the bayonet to be attached to a [[bayonet lug]]. A sword bayonet could be used in combat as a [[Sidearm (weapon)|sidearm]], when detached from the musket or rifle. When the bayonet was attached to the musket or rifle, it effectively turned all  [[long gun]]s into a [[spear]] or [[glaive]], which made it suitable for both thrusting and cutting attacks.

While the British Army eventually discarded the sword bayonet, the socket bayonet survived the introduction of the rifled musket into British service in 1854. The new rifled musket copied the French locking ring system.<ref name="COLD"/> The new bayonet proved its worth at the [[Battle of Alma]] and the [[Battle of Inkerman]] during the [[Crimean War]], where the Imperial Russian Army learned to fear it.<ref name="COLD"/>

In the 1860s, European nations began to develop new [[bolt-action]] [[breech-loading weapon|breechloading]] [[rifle]]s (such as the [[Chassepot]] and [[Snider–Enfield]]) and sword bayonets suitable for mass production and used by police, pioneer, and engineer troops.<ref name="OWE">Owen, John Ivor Headon, ''Brassey's Infantry Weapons of the World: Infantry Weapons and Combat Aids in Current Use by the Regular and Reserve Forces of All Nations'', Bonanza Press,  {{ISBN|978-0-517-24234-6}} (1975), p. 265</ref> The decision to redesign the bayonet into a short sword was viewed by some as an acknowledgement of the decline in importance of the fixed bayonet as a weapon in the face of new advances in firearms technology.<ref name="PUN"/> As a British newspaper put it, "the committee, in recommending this new sword bayonet, appear to have had in view the fact that bayonets will henceforth be less frequently used than in former times as a weapon of offence and defence; they desired, therefore, to substitute an instrument of more general utility."<ref name="PUN"/>
