A halberd (also called halbard, halbert or Swiss voulge) is a two-handed pole weapon that came to prominent use during the 14th and 15th centuries. The word halberd may come from the German words Halm (staff), and Barte (axe). In modern-day German, the weapon is called a Hellebarde. The halberd consists of an axe blade topped with a spike mounted on a long shaft. It always has a hook or thorn on the back side of the axe blade for grappling mounted combatants. It is very similar to certain forms of the voulge in design and usage. The halberd was usually 1.5 to 1.8 metres (5 to 6 feet) long.
The halberd was inexpensive to produce and very versatile in battle. As the halberd was eventually refined, its point was more fully developed to allow it to better deal with spears and pikes (also able to push back approaching horsemen), as was the hook opposite the axe head, which could be used to pull horsemen to the ground. A Swiss peasant used a halberd to kill Charles the Bold, the Duke of Burgundy—decisively ending the Burgundian Wars, literally in a single stroke. Researchers suspect that a halberd or a bill sliced through the back of King Richard III's skull at the Battle of Bosworth.
The halberd was the primary weapon of the early Swiss armies in the 14th and early 15th centuries. Later, the Swiss added the pike to better repel knightly attacks and roll over enemy infantry formations, with the halberd, hand-and-a-half sword, or the dagger known as the Schweizerdolch used for closer combat. The German Landsknechte, who imitated Swiss warfare methods, also used the pike, supplemented by the halberd—but their side arm of choice was a short sword called the Katzbalger.
