A bayonet is a short sword attached to the muzzle of a firearm. The bayonet was placed inside the barrel of the muzzle loading muskets of the late 17th century. The sock or ring bayonet, invented 1700, allowed a weapon to be fired without interruption, leading to the demise of the pike. Since the 1700s, bayonets have evolved into a variety of types. During the Great War, the French used a long needle bayonet, the British a sword bayonet, while the Germans adopted a 'pioneer' bayonet with the rear edge formed into a saw. As armies have become more mechanised, bayonets have tended to decrease in length. Although many military leaders have advocated the use of the bayonet, in practice it has been rarely used.
