Pike (weapon)

A pike is a pole weapon, a very long thrusting spear formerly used extensively by infantry. Unlike many similar weapons, the pike is not intended to be thrown. Pikes were used regularly in European warfare from the early Middle Ages until around 1700, and were wielded by foot soldiers deployed in close quarters. The pike found extensive use with Landsknecht armies and Swiss mercenaries, who employed it as their main weapon and used it in pike square formations. A similar weapon, the sarissa, was also used by Alexander the Great's Macedonian phalanx infantry to great effect. Generally, a spear becomes a pike when it is too long to be wielded with one hand in combat.

The pike was a long weapon, varying considerably in size, from 3 to 7.5 metres (10 to 25 feet) long. It was approximately 2.5–6 kg (5.5–13.2 lb) in weight, with sixteenth-century military writer Sir John Smythe recommending lighter rather than heavier pikes. It had a wooden shaft with an iron or steel spearhead affixed. The shaft near the head was often reinforced with metal strips called "cheeks" or langets. When the troops of opposing armies both carried the pike, it often grew in a sort of arms race, getting longer in both shaft and head length to give one side's pikemen an edge in combat. The extreme length of such weapons required a strong wood such as well-seasoned ash for the pole, which was tapered towards the point to prevent the pike from sagging on the ends, although drooping or slight flection of the shaft was always a problem in pike handling. It is a common mistake to refer to a bladed polearm as a pike; such weapons are more generally halberds, glaives or voulges.

The great length of the pikes allowed a great concentration of spearheads to be presented to the enemy, with their wielders at a greater distance, but also made pikes unwieldy in close combat. This meant that pikemen had to be equipped with an additional, shorter weapon such as a sword, mace, or dagger in order to defend themselves should the fighting degenerate into a melee. In general, however, pikemen attempted to avoid such disorganized combat, in which they were at a disadvantage. To compound their difficulties in a melee, the pikeman often did not have a shield, or had only a small shield which would be of limited use in close-quarters fighting.
