The English longbow dominated European battlefields for roughly 150 years because it combined raw hitting power, extraordinary rate of fire, and massed tactical deployment in ways no other medieval weapon could match. A single archer could loose 10 to 12 arrows per minute, and an army of 5,000 archers could send 50,000 arrows downrange in sixty seconds. That volume of fire, delivered from hundreds of yards away, could break a cavalry charge before it ever reached the front line.
Draw Weight and Hitting Power
The longbows recovered from the wreck of the Mary Rose, Henry VIII’s warship that sank in 1545, give us the best physical evidence of what these weapons could do. Analysis of the 137 surviving bows found draw weights ranging from 65 to 175 pounds, with the majority clustering around 110 pounds. For comparison, most modern recreational bows pull between 30 and 50 pounds. A war longbow required roughly two to three times more force to draw.
That force translated directly into kinetic energy. Testing by researcher Mark Stretton using a 144-pound yew longbow firing a heavy 3.6-ounce war arrow produced about 114 joules of energy at the point of release, with the arrow traveling at roughly 155 feet per second. Lighter arrows flew faster and farther but carried less punch. Heavier “sheaf” arrows sacrificed some range for devastating close-range impact. Depending on arrow weight, the effective range stretched from about 140 to 300 meters, with a maximum flight distance of around 275 meters for heavier shafts.
What It Could (and Couldn’t) Pierce
Longbow arrows came fitted with different heads for different purposes. The bodkin point, a narrow, squared-off steel tip, was designed specifically to punch through armor. Modern testing confirms it worked, but with important caveats that depended on range, armor quality, and arrow construction.
A 75-pound longbow firing a bodkin point at 10 yards penetrated both a padded jacket (gambeson) and chainmail in tests conducted in 2006 and 2014. Against plate armor of minimum thickness (about 1.2 mm), bodkin arrows could punch through, though likely not deep enough to kill. A 2017 computer simulation suggested heavy bodkin arrows could penetrate typical plate armor even at 225 meters, though only slightly, with penetration increasing at closer range or against lower-quality steel.
However, a well-publicized 2019 practical test by historian Tobias Capwell and the Tod’s Workshop team challenged that optimism. Using a reproduction 15th-century breastplate over chainmail and gambeson, they fired both wrought iron and case-hardened arrows from a 160-pound longbow at 25 meters. Neither arrow penetrated the breastplate. The takeaway: the longbow was lethal against lightly armored troops, horses, and gaps in plate armor, but top-quality plate could stop it. This helps explain why late medieval knights invested heavily in full plate harness as the longbow threat grew.
Rate of Fire vs. the Crossbow
The longbow’s most decisive advantage over its main rival, the crossbow, was speed. A trained archer could loose 10 to 12 aimed shots per minute. A crossbowman, who had to use a mechanical device to wind back the string after each shot, managed two to four. In a pitched battle, this meant English archers could saturate an area with arrows continuously, creating a killing zone that cavalry and infantry had to cross under relentless fire. The crossbow hit harder per bolt and required far less training, but on a battlefield where thousands of projectiles per minute mattered more than individual accuracy, the longbow’s rate of fire was the deciding factor.
A Lifetime of Training
Drawing a 100-plus-pound bow smoothly and accurately, then doing it hundreds of times in a battle, required physical conditioning that started in childhood. English law mandated archery practice, and by 1470, an edict required compulsory training in the longbow. This wasn’t ceremonial. It reshaped bodies.
Skeletal analysis of medieval archers shows measurable changes in bone structure from years of repetitive loading. Studies of warriors trained with longbows found decreased asymmetry in upper arm bone thickness compared to soldiers who trained with swords or other one-handed weapons. The bow arm (typically the left) developed increased bone density and robustness to handle the sustained force of holding a heavy bow at full draw. These skeletal markers have been observed even in Neolithic archers using lighter bows, suggesting that the far heavier medieval longbow placed extreme demands on the body. Pathological changes directly associated with archery, including stress markers on muscle attachment points, appear in both historical remains and modern competitive archers.
This training requirement was both the longbow’s greatest strength and its strategic limitation. You couldn’t raise a force of longbowmen in a few months. England’s archery culture, built over generations through village practice and legal mandates, gave it a military resource that France and other rivals simply couldn’t replicate quickly.
Tactical Deployment on the Battlefield
Raw weapon performance only mattered because English commanders learned to use archers within smart tactical frameworks. The battles of Crécy (1346), Poitiers (1356), and Agincourt (1415) all followed a similar pattern: English forces chose defensive positions, dismounted their knights, and placed large formations of archers on the flanks or in forward positions.
At Agincourt, archers drove sharpened wooden stakes into the ground at an angle in front of their positions, creating an improvised barrier against cavalry. When the French cavalry charged, they couldn’t overwhelm the archer lines. The horses either impaled themselves on the stakes or veered away in panic, already riddled with arrows. The next wave of French knights on foot, funneled by a narrowing field, became so tightly packed they couldn’t swing their weapons effectively. The archers then dropped their bows, picked up swords and mallets, and waded into the disordered mass.
This combination of terrain selection, defensive obstacles, and massed archery turned the longbow from a weapon into a system. The arrows didn’t need to kill every knight outright. They killed horses, wounded men through gaps in armor, exhausted and demoralized attackers during a long approach, and broke formations apart before close combat even began.
Supply Chain Behind the Weapon
Keeping thousands of archers equipped required an industrial-scale supply effort. The best longbows were made from yew, and England’s demand eventually outstripped domestic supply. Parliament passed the Statute of Westminster in 1472, requiring every ship arriving at an English port to pay a tax of four bow staves per tun of cargo. This effectively turned international trade into a yew importation pipeline, drawing staves from Spain, Italy, and the Baltic. The statute was a direct response to shortages caused by the 1470 compulsory training edict: more archers practicing meant more bows breaking and more raw material needed.
Arrows were consumed in even greater quantities. A single battle could burn through tens of thousands of shafts. The English crown maintained dedicated fletchers and stockpiled arrows in royal armories, treating ammunition supply as a core logistical concern rather than an afterthought.
Why Its Dominance Eventually Ended
The longbow declined not because a better bow replaced it, but because gunpowder weapons eliminated its core advantage. Early firearms were slower, less accurate, and less powerful than a longbow in trained hands. But training a musketeer took weeks, not years. As plate armor improved to resist arrows and firearms became more reliable through the 16th century, the calculus shifted. A kingdom could field thousands of gunners from its general population. It could never field thousands of longbowmen without a decades-long cultural investment in archery. The weapon that won Agincourt was ultimately defeated by economics and demographics, not by superior technology.
