Crossbows

Ranged Weapons — Subcategory

Overview

The crossbow is a ranged weapon consisting of a bow (the prod or lath) mounted horizontally on a stock, with a mechanical lock (the nut) that holds the drawn string until the trigger is pulled. This design allows the weapon to be drawn, loaded, and held ready without muscular effort — the user can aim carefully without fighting the draw weight. This made the crossbow accessible to soldiers without years of specialized training, unlike the longbow, and was deeply threatening to the armored nobility.

Advantages Over the Bow

• Training — A soldier could be trained to effective crossbow use in weeks; the longbow required years
• Draw weight — Medieval crossbows were drawn at 200–1,000 lbs (using mechanical aids); far exceeding any hand bow; exceptional penetration against armor
• Holding — The lock holds the drawn string; the crossbowman can take extended aim without fatigue
• Deployment from cover — A crossbowman could shelter, quickly emerge, aim, fire, and retreat

Disadvantages vs. the Bow

• Rate of fire — 1–3 bolts per minute vs. 10–12 arrows for a longbow; loading mechanisms were slow
• Weather — The prod (bow element) was affected by moisture; strings absorbed water; longbows could be unstrung and kept dry more easily
• Size — Crossbows were bulkier and heavier than bows

Loading Mechanisms

As draw weights increased, mechanical aids became necessary:

• Belt hook — User hooks the string to a belt hook, straightens up using body weight; simple; limited to ~200 lb
• Goat's foot lever (pied de biche) — Hinged lever over the stock; hooks the string and draws it back; moderate draw weight
• Cranequin (rack and pinion) — Gear-and-rack mechanism; slower but handles very high draw weights; used on heavy war crossbows
• Windlass — Pulleys and ropes; slowest; handles the heaviest draw weights (500–1,000 lbs); crossbow artillery

The Bolt (Quarrel)

Crossbow projectiles are shorter and heavier than arrows:

• Bodkin bolt — Square or diamond cross-section iron point; armor-piercing; could penetrate chainmail and light plate at combat range
• Blunt bolt — For hunting small game; stuns without destroying
• Length: typically 25–35 cm

Historical Impact

The Church Attempts to Ban It

The Second Lateran Council (1139) banned the crossbow's use against Christians — a measure of its perceived threat to the armored knight. The ban was universally ignored.

Genoese Crossbowmen

Professional Genoese crossbowmen were the most prized mercenary ranged troops of the 13th–14th centuries — hired across Europe and the Middle East. Their failure at Crécy (1346) — outranged by English longbowmen, with wet strings from rain — was one of the most studied tactical disasters of the medieval period.

Chinese Crossbow

China had a sophisticated crossbow tradition predating Europe's by centuries:

• Bronze crossbow mechanisms from the 5th century BCE
• Used in mass formations; thousands of soldiers armed with multiple crossbows could deliver sustained fire

Decline and Legacy

The crossbow declined militarily as firearms became reliable (16th century), requiring no more training but delivering greater penetration. The crossbow survives in:

• Sport and competitive target shooting
• Hunting (legal in US states where it's permitted during archery seasons)
• Special military applications (silent ranged weapon)
