Medieval warfare

Medieval warfare is the European warfare of the Middle Ages. Technological, cultural, and social developments had forced a severe transformation in the character of warfare from antiquity, changing military tactics and the role of cavalry and artillery (see military history). In terms of fortification, the Middle Ages saw the emergence of the castle in Europe, which then spread to the Holy Land (modern day Israel and Palestine).

Strategy and tactics

De re militari

si vis pacem, para bellum
If you want peace, prepare for war

Vegetius, De re militari, preface to book 3.

Publius Flavius Vegetius Renatus wrote De re militari (Concerning Military Matters) possibly in the late 4th century. Described by historian Walter Goffart as "the bible of warfare throughout the Middle Ages", De re militari was widely distributed through the Latin West. While Western Europe relied on a single text for the basis of its military knowledge, the Byzantine Empire in Southeastern Europe had a succession of military writers. Though Vegetius had no military experience and De re militari was derived from the works of Cato and Frontinus, his books were the standard for military discourse in Western Europe from their production until the 16th century.

De re militari was divided into five books: who should be a soldier and the skills they needed to learn, the composition and structure of an army, field tactics, how to conduct and withstand sieges, and the role of the navy. According to Vegetius, infantry was the most important element of an army because it was cheap compared to cavalry and could be deployed on any terrain. One of the tenets he put forward was that a general should only engage in battle when he was sure of victory or had no other choice. As archaeologist Robert Liddiard explains, "Pitched battles, particularly in the eleventh and twelfth centuries, were rare."

Although his work was widely reproduced, and over 200 copies, translations, and extracts survive today, the extent to which Vegetius affected the actual practice of warfare as opposed to its concept is unclear because of his habit of stating the obvious. Historian Michael Clanchy noted "the medieval axiom that laymen are illiterate and its converse that clergy are literate", so it may be the case that few soldiers read Vegetius' work. While their Roman predecessors were well-educated and had been experienced in warfare, the European nobility of the early Medieval period were not renowned for their education, but from the 12th century, it became more common for them to read.

Some soldiers regarded the experience of warfare as more valuable than reading about it; for example, Geoffroi de Charny, a 14th century knight who wrote about warfare, recommended that his audience should learn by observing and asking advice from their superiors. Vegetius remained prominent in medieval literature on warfare, although it is uncertain to what extent his work was read by the warrior class as opposed to the clergy. In 1489, King Henry VII of England commissioned the translation of De re militari into English, "so every gentleman born to arms and all manner of men of war, captains, soldiers, victuallers and all others would know how they ought to behave in the feats of wars and battles".

Fortifications

In Europe, breakdowns in centralized power led to the rise of several groups that turned to large-scale pillage as a source of income. Most notably the Vikings, Arabs, Mongols, Huns, Cumans, Tartars, and Magyars raided significantly. As these groups were generally small and needed to move quickly, building fortifications was a good way to provide refuge and protection for the people and the wealth in the region.

These fortifications evolved throughout the Middle Ages, the most important form being the castle, a structure which has become almost synonymous with the Medieval era in the popular eye. The castle served as a protected place for the local elites. Inside a castle they were protected from bands of raiders and could send mounted warriors to drive the enemy from the area, or to disrupt the efforts of larger armies to supply themselves in the region by gaining local superiority over foraging parties that would be impossible against the whole enemy host.

Fortifications were a very important part of warfare because they provided safety to the lord, his family, and his servants. They provided refuge from armies too large to face in open battle. The ability of the heavy cavalry to dominate a battle on an open field was useless against fortifications. Building siege engines was a time-consuming process, and could seldom be effectively done without preparations before the campaign. Many sieges could take months, if not years, to weaken or demoralize the defenders sufficiently. Fortifications were an excellent means of ensuring that the elite could not be easily dislodged from their lands – as Count Baldwin of Hainaut commented in 1184 on seeing enemy troops ravage his lands from the safety of his castle, "they can't take the land with them".

Siege warfare

In the Medieval period besieging armies used a wide variety of siege engines including: scaling ladders; battering rams; siege towers and various types of catapults such as the mangonel, onager, ballista, and trebuchet. Siege techniques also included mining in which tunnels were dug under a section of the wall and then rapidly collapsed to destabilize the wall's foundation. Another technique was to bore into the enemy walls, however, this was not nearly as effective as other methods due to the thickness of castle walls.

The Walls of Dubrovnik are a series of defensive stone walls, never breached by a hostile army, that have surrounded and protected the maritime city-state of Dubrovnik (Ragusa), situated in southern Croatia.

Advances in the prosecution of sieges encouraged the development of a variety of defensive counter-measures. In particular, Medieval fortifications became progressively stronger – for example, the advent of the concentric castle from the period of the Crusades – and more dangerous to attackers – witness the increasing use of machicolations, as well the preparation of hot or incendiary substances. Arrow slits, concealed doors for sallies, and deep water wells were also integral to resisting siege at this time. Designers of castles paid particular attention to defending entrances, protecting gates with drawbridges, portcullises and barbicans. Wet animal skins were often draped over gates to repel fire. Moats and other water defences, whether natural or augmented, were also vital to defenders.

In the Middle Ages, virtually all large cities had city wallsDubrovnik in Dalmatia is an impressive and well-preserved example – and more important cities had citadels, forts or castles. Great effort was expended to ensure a good water supply inside the city in case of siege. In some cases, long tunnels were constructed to carry water into the city. In other cases, such as the Ottoman siege of Shkodra, Venetian engineers had designed and installed cisterns that were fed by rain water channeled by a system of conduits in the walls and buildings. Complex systems of tunnels were used for storage and communications in medieval cities like Tábor in Bohemia. Against these would be matched the mining skills of teams of trained sappers, who were sometimes employed by besieging armies.

Until the invention of gunpowder-based weapons (and the resulting higher-velocity projectiles), the balance of power and logistics favoured the defender. With the invention of gunpowder, the traditional methods of defence became less and less effective against a determined siege.

Organization

The medieval knight was usually a mounted and armoured soldier, often connected with nobility or royalty, although (especially in north-eastern Europe) knights could also come from the lower classes, and could even be enslaved persons. The cost of their armour, horses, and weapons was great; this, among other things, helped gradually transform the knight, at least in western Europe, into a distinct social class separate from other warriors. During the crusades, holy orders of Knights fought in the Holy Land (see Knights Templar, the Hospitallers, etc.).

The light cavalry consisted usually of lighter armed and armoured men, who could have lances, javelins or missile weapons, such as bows or crossbows. In much of the Middle Ages, light cavalry usually consisted of wealthy commoners. Later in the Middle Ages, light cavalry would also include sergeants who were men who had trained as knights but could not afford the costs associated with the title. Light cavalry was used as scouts, skirmishers or outflankers. Many countries developed their styles of light cavalries, such as Hungarian mounted archers, Spanish jinetes, Italian and German mounted crossbowmen and English currours.

The infantry was recruited and trained in a wide variety of manners in different regions of Europe all through the Middle Ages, and probably always formed the most numerous part of a medieval field army. Many infantrymen in prolonged wars would be mercenaries. Most armies contained significant numbers of spearmen, archers and other unmounted soldiers.

Recruiting

Hungarian raids in the 10th century. Before the battle of Lechfeld in 955 Medieval Europeans were vulnerable from the Nomadic style of war that came from the Hungarians.

In the earliest Middle Ages, it was the obligation of every noble to respond to the call to battle with his equipment, archers, and infantry. This decentralized system was necessary due to the social order of the time but could lead to motley forces with variable training, equipment and abilities. The more resources the noble had access to, the better his troops would typically be.

Typically the feudal armies consisted of a core of highly skilled knights and their household troops, mercenaries hired for the time of the campaign and feudal levies fulfilling their feudal obligations, who usually were little more than rabble. They could, however, be efficient in disadvantageous terrain. Towns and cities could also field militias.

As central governments grew in power, a return to the citizen and mercenary armies of the classical period also began, as central levies of the peasantry began to be the central recruiting tool. It was estimated that the best infantrymen came from the younger sons of free land-owning yeomen, such as the English archers and Swiss pikemen. England was one of the most centralized states in the Late Middle Ages, and the armies that fought the Hundred Years' War were mostly paid professionals.

In theory, every Englishman had an obligation to serve for forty days. Forty days was not long enough for a campaign, especially one on the continent. Thus the scutage was introduced, whereby most Englishmen paid to escape their service and this money was used to create a permanent army. However, almost all high medieval armies in Europe were composed of a great deal of paid core troops, and there was a large mercenary market in Europe from at least the early 12th century.

As the Middle Ages progressed in Italy, Italian cities began to rely mostly on mercenaries to do their fighting rather than the militias that had dominated the early and high medieval period in this region. These would be groups of career soldiers who would be paid a set rate. Mercenaries tended to be effective soldiers, especially in combination with standing forces, but in Italy, they came to dominate the armies of the city-states. This made them problematic; while at war they were considerably more reliable than a standing army, at peacetime they proved a risk to the state itself like the Praetorian Guard had once been.

Mercenary-on-mercenary warfare in Italy led to relatively bloodless campaigns which relied as much on manoeuvre as on battles, since the condottieri recognized it was more efficient to attack the enemy's ability to wage war rather than his battle forces, discovering the concept of indirect warfare 500 years before Sir Basil Liddell Hart, and attempting to attack the enemy supply lines, his economy and his ability to wage war rather than risking an open battle, and manoeuvre him into a position where risking a battle would have been suicidal. Machiavelli understood this indirect approach as cowardice.

Weapons Medieval weapons consisted of many different types of ranged and hand-held objects:

Armour

Artillery and Siege engine

Animals

Relics

The practice of carrying relics into battle is a feature that distinguishes medieval warfare from its predecessors or early modern warfare and possibly inspired by biblical references. The presence of relics was believed to be an important source of supernatural power that served both as a spiritual weapon and a form of defence; the relics of martyrs were considered by Saint John Chrysostom much more powerful than "walls, trenches, weapons and hosts of soldiers"

In Italy, the carroccio or carro della guerra, the "war wagon", was an elaboration of this practice that developed during the 13th century. The carro della guerra of Milan was described in detail in 1288 by Bonvesin de la Riva in his book on the "Marvels of Milan". Wrapped in scarlet cloth and drawn by three yoke of oxen that were caparisoned in white with the red cross of Saint Ambrose, the city's patron, it carried a crucifix so massive it took four men to step it in place, like a ship's mast.

Supplies and logistics

Medieval warfare largely predated the use of supply trains, which meant that armies had to acquire food supplies from the territory they were passing through. This meant that large-scale looting by soldiers was unavoidable, and was actively encouraged in the 14th century with its emphasis on chevauchée tactics, where mounted troops would burn and pillage enemy territory in order to distract and demoralize the enemy while denying them their supplies.

Through the medieval period, soldiers were responsible for supplying themselves, either through foraging, looting, or purchases. Even so, military commanders often provided their troops with food and supplies, but this would be provided instead of the soldiers' wages, or soldiers would be expected to pay for it from their wages, either at cost or even with a profit.

In 1294, the same year John II de Balliol of Scotland refused to support Edward I of England's planned invasion of France, Edward I implemented a system in Wales and Scotland where sheriffs would acquire foodstuffs, horses and carts from merchants with compulsory sales at prices fixed below typical market prices under the Crown's rights of prise and purveyance. These goods would then be transported to Royal Magazines in southern Scotland and along the Scottish border where English conscripts under his command could purchase them. This continued during the First War of Scottish Independence which began in 1296, though the system was unpopular and was ended with Edward I's death in 1307.

Starting under the rule of Edward II in 1307 and ending under the rule of Edward III in 1337, the English instead used a system where merchants would be asked to meet armies with supplies for the soldiers to purchase. This led to discontent as the merchants saw an opportunity to profiteer, forcing the troops to pay well above normal market prices for food.

As Edward III went to war with France in the Hundred Years' War (starting in 1337), the English returned to a practice of foraging and raiding to meet their logistical needs. This practice lasted throughout the war, extending through the remainder of Edward III's reign into the reign of Henry VI.

Naval warfare

The waters surrounding Europe can be grouped into two types which affected the design of craft that traveled and therefore the warfare. The Mediterranean and Black Seas were free of large tides, generally calm, and had predictable weather. The seas around the north and west of Europe experienced stronger and less predictable weather. The weather gauge, the advantage of having a following wind, was an important factor in naval battles, particularly to the attackers. Typically westerlies (winds blowing from west to east) dominated Europe, giving naval powers to the west an advantage. Medieval sources on the conduct of medieval naval warfare are less common than those about land-based war. Most medieval chroniclers had no experience of life on the sea and generally were not well informed. Maritime archaeology has helped provide information.

Early in the medieval period, ships in the context of warfare were used primarily for transporting troops. In the Mediterranean, naval warfare in the Middle Ages was similar to that under late Roman Empire: fleets of galleys would exchange missile fire and then try to board bow first to allow marines to fight on deck. This mode of naval warfare remained the same into the early modern period, as, for example, at the Battle of Lepanto. Famous admirals included Roger of Lauria, Andrea Doria and Hayreddin Barbarossa.

Galleys were not suitable for the colder and more turbulent North Sea and the Atlantic Ocean, although they saw occasional use. Bulkier ships were developed which were primarily sail-driven, although the long lowboard Viking-style rowed longship saw use well into the 15th century. Their main purpose in the north remained the transportation of soldiers to fight on the decks of the opposing ship (as, for example, at the Battle of Svolder or the Battle of Sluys).

Late medieval sailing warships resembled floating fortresses, with towers in the bows and at the stern (respectively, the forecastle and aftcastle). The large superstructure made these warships quite unstable, but the decisive defeats that the more mobile but considerably lower boarded longships suffered at the hands of high-boarded cogs in the 15th century ended the issue of which ship type would dominate northern European warfare.

Introduction of guns

The introduction of guns was the first steps towards major changes in naval warfare, but it only slowly changed the dynamics of ship-to-ship combat. The first guns on ships were introduced in the 14th century and consisted of small wrought-iron pieces placed on the open decks and in the fighting tops, often requiring only one or two men to handle them. They were designed to injure, kill or simply stun, shock and frighten the enemy before boarding.

As guns were made more durable to withstand stronger gunpowder charges, they increased their potential to inflict critical damage to the vessel rather than just their crews. Since these guns were much heavier than the earlier anti-personnel weapons, they had to be placed lower in the ships, and fire from gunports, to avoid ships becoming unstable. In Northern Europe the technique of building ships with clinker planking made it difficult to cut ports in the hull; clinker-built (or clench-built) ships had much of their structural strength in the outer hull. The solution was the gradual adoption of carvel-built ships that relied on an internal skeleton structure to bear the weight of the ship.

Two views of a hand culverin and two small cannons from the 15th century.

The first ships to actually mount heavy cannon capable of sinking ships were galleys, with large wrought-iron pieces mounted directly on the timbers in the bow. The first example is known from a woodcut of a Venetian galley from 1486. Heavy artillery on galleys was mounted in the bow which fit conveniently with the long-standing tactical tradition of attacking head-on and bow-first. The ordnance on galleys was quite heavy from its introduction in the 1480s, and capable of quickly demolishing medieval-style stone walls that still prevailed until the 16th century.

This temporarily upended the strength of older seaside fortresses, which had to be rebuilt to cope with gunpowder weapons. The addition of guns also improved the amphibious abilities of galleys as they could assault supported with heavy firepower, and could be even more effectively defended when beached stern-first. Galleys and similar oared vessels remained uncontested as the most effective gun-armed warships in theory until the 1560s, and in practice for a few decades more, and were considered a grave risk to sailing warships.

Rise of infantry

In the Medieval period, the mounted cavalry long held sway on the battlefield. Heavily armoured mounted knights represented a formidable foe for reluctant peasant draftees and lightly armoured freemen. To defeat mounted cavalry, infantry used swarms of missiles or a tightly packed phalanx of men, techniques honed in antiquity by the Greeks.

Swiss pikemen

The use of long pikes and densely packed foot troops was not uncommon in the Middle Ages. The Flemish footmen at the Battle of the Golden Spurs met and overcame French knights in 1302, as the Lombards did in Legnano in 1176 and the Scots held their own against heavily armoured English cavalry. During the St. Louis crusade, dismounted French knights formed a tight lance-and-shield phalanx to repel Egyptian cavalry. The Swiss used pike tactics in the late medieval period. While pikemen usually grouped and awaited a mounted attack, the Swiss developed flexible formations and aggressive manoeuvring, forcing their opponents to respond. The Swiss won at Morgarten, Laupen, Sempach, Grandson and Murten, and between 1450 and 1550 every leading prince in Europe (except the English and Scottish) hired Swiss pikemen, or emulated their tactics and weapons (e.g., the German Landsknechte).

Welsh and English longbowmen

The Welsh & English longbowman used a single-piece longbow (but some bows later developed a composite design) to deliver arrows that could penetrate contemporary mail and damage/dent plate armour. The longbow was a difficult weapon to master, requiring long years of use and constant practice. A skilled longbowman could shoot about 12 shots per minute. This rate of fire was far superior to competing weapons like the crossbow or early gunpowder weapons. The nearest competitor to the longbow was the much more expensive crossbow, used often by urban militias and mercenary forces. The crossbow had greater penetrating power and did not require the extended years of training. However, it lacked the rate of fire of the longbow.

At Crécy and Agincourt bowmen unleashed clouds of arrows into the ranks of knights. At Crécy, even 5,000 Genoese crossbowmen could not dislodge them from their hill. At Agincourt, thousands of French knights were brought down by armour-piercing bodkin point arrows and horse-maiming broadheads. Longbowmen decimated an entire generation of the French nobility.

Transition to gunpowder warfare

In 1326 the earliest known European picture of a gun appeared in a manuscript by Walter de Milemete. In 1350, Petrarch wrote that the presence of cannons on the battlefield was 'as common and familiar as other kinds of arms'.

Early artillery played a limited role in the Hundred Years' War, and it became indispensable in the Italian Wars of 1494–1559, marking the beginning of early modern warfare. Charles VIII, during his invasion of Italy, brought with him the first truly mobile siege train: culverins and bombards mounted on wheeled carriages, which could be deployed against an enemy stronghold immediately after arrival.

Medieval conquerors

Arabs

The initial Muslim conquests began in the 7th century after the death of the Islamic prophet Muhammad, and were marked by a century of rapid Arab expansion beyond the Arabian Peninsula under the Rashidun and Umayyad Caliphates. Under the Rashidun, the Arabs conquered the Persian Empire, along with Roman Syria and Roman Egypt during the Byzantine-Arab Wars, all within just seven years from 633 to 640. Under the Umayyads, the Arabs annexed North Africa and southern Italy from the Romans and the Arab Empire soon stretched from parts of the Indian subcontinent, across Central Asia, the Middle East, North Africa, and southern Italy, to the Iberian Peninsula and the Pyrenees.

The early Arab army mainly consisted of camel-mounted infantry, alongside a few Bedouin cavalry. Constantly outnumbered by their opponent, they did, however, possess the advantage of strategic mobility, their camel-borne nature allowing them to constantly outmanoeuvre larger Byzantine and Sassanid armies to take prime defensive positions. The Rashidun cavalry, while lacking the number and mounted archery skill of their Roman and Persian counterparts was for the most part skillfully employed, and played a decisive role in many crucial battles such as Battle of Yarmouk.

In contrast, the Roman army and Persian army at the time both had large numbers of heavy infantry and heavy cavalry (cataphracts and clibanarii) that were better equipped, heavily protected, and more experienced and disciplined. The Arab invasions came at a time when both ancient powers were exhausted from the protracted Byzantine–Sassanid Wars, particularly the bitterly fought Byzantine–Sassanid War of 602–628 which had brought both empires close to collapse. Also, the typically multi-ethnic Byzantine force was always wracked by dissension and lack of command unity, a similar situation also being encountered among the Sassanids who had been embroiled in a bitter civil war for a decade before the coming of the Arabs. In contrast, the Ridda Wars had forged the Caliphate's army into a united and loyal fighting force.

Vikings

The Vikings were a feared force in Europe because of their savagery and speed of their attacks. Whilst seaborne raids were nothing new at the time, the Vikings refined the practice to a science through their shipbuilding, tactics and training. Unlike other raiders, the Vikings made a lasting impact on the face of Europe. During the Viking age, their expeditions, frequently combining raiding and trading, penetrated most of the old Frankish Empire, the British Isles, the Baltic region, Russia, and both Muslim and Christian Iberia. Many served as mercenaries, and the famed Varangian Guard, serving the Emperor of Constantinople, was drawn principally of Scandinavian warriors.

Viking longships were swift and easily manoeuvered; they could navigate deep seas or shallow rivers, and could carry warriors that could be rapidly deployed directly onto land due to the longships being able to land directly. The longship was the enabler of the Viking style of warfare that was fast and mobile, relying heavily on the element of surprise, and they tended to capture horses for mobility rather than carry them on their ships. The usual method was to approach a target stealthily, strike with surprise and then retire swiftly. The tactics used were difficult to stop, for the Vikings, like guerrilla-style raiders elsewhere, deployed at a time and place of their choosing. The fully armoured Viking raider would wear an iron helmet and a mail hauberk, and fight with a combination of axe, sword, shield, spear or great "Danish" two-handed axe, although the typical raider would be unarmoured, carrying only a bow and arrows, a knife "seax", a shield and spear; the swords and the axes were much less common.

Almost by definition, opponents of the Vikings were ill-prepared to fight a force that struck at will, with no warning. European countries with a weak system of government would be unable to organize a suitable response and would naturally suffer the most to Viking raiders. Viking raiders always had the option to fall back in the face of a superior force or stubborn defence and then reappear to attack other locations or retreat to their bases in what is now Sweden, Denmark, Norway and their Atlantic colonies. As time went on, Viking raids became more sophisticated, with coordinated strikes involving multiple forces and large armies, as the "Great Heathen Army" that ravaged Anglo-Saxon England in the 9th century. In time, the Vikings began to hold on to the areas they raided, first wintering and then consolidating footholds for further expansion later.

With the growth of centralized authority in the Scandinavian region, Viking raids, always an expression of "private enterprise", ceased and the raids became pure voyages of conquest. In 1066, King Harald Hardråde of Norway invaded England, only to be defeated by Harold Godwinson, who in turn was defeated by William of Normandy, descendant of the Viking Rollo, who had accepted Normandy as a fief from the Frankish king. The three rulers had their claims to the English crown (Harald probably primarily on the overlord-ship of Northumbria) and it was this that motivated the battles rather than the lure of plunder.

At that point, the Scandinavians had entered their medieval period and consolidated their kingdoms of Denmark, Norway, and Sweden. This period marks the end of significant raider activity both for plunder or conquest. The resurgence of centralized authority throughout Europe limited opportunities for traditional raiding expeditions in the West, whilst the Christianisation of the Scandinavian kingdoms themselves encouraged them to direct their attacks against the still predominantly pagan regions of the eastern Baltic. The Scandinavians started adapting more continental European ways, whilst retaining an emphasis on naval power – the "Viking" clinker-built warship was used in the war until the 14th century at least. However, developments in shipbuilding elsewhere removed the advantage the Scandinavian countries had previously enjoyed at sea, whilst castle building throughout frustrated and eventually ended Viking raids. Natural trading and diplomatic links between Scandinavia and Continental Europe ensured that the Scandinavians kept up to date with continental developments in warfare.

The Scandinavian armies of the High Middle Ages followed the usual pattern of the Northern European armies, but with a stronger emphasis on infantry. The terrain of Scandinavia favoured heavy infantry, and whilst the nobles fought mounted in the continental fashion, the Scandinavian peasants formed a well-armed and well-armoured infantry, of which approximately 30% to 50% would be archers or crossbowmen. The crossbow, the flatbow and the longbow were especially popular in Sweden and Finland. The chainmail, the lamellar armour and the coat of plates were the usual Scandinavian infantry armour before the era of plate armour.

Mongols

During The Mongol invasion of Europe, Tatars, under the leadership of Kadan, experienced a major failure in March 1242 at Klis Fortress in southern Croatia.
 

By 1241, having conquered large parts of Russia, the Mongols continued the invasion of Europe with a massive three-pronged advance, following the fleeing Cumans, who had established an uncertain alliance with King Bela IV of Hungary. They first invaded Poland, and finally, Hungary, culminating in the crushing defeat of the Hungarians in the Battle of Mohi. The Mongol aim seems to have consistently been to defeat the Hungarian-Cuman alliance. The Mongols raided across the borders to Austria and Bohemia in the summer when the Great Khan died, and the Mongol princes returned home to elect a new Great Khan.

The Golden Horde would frequently clash with Hungarians, Lithuanians and Poles in the thirteenth century, with two large raids in the 1260s and 1280s respectively. In 1284 the Hungarians repelled the last major raid into Hungary, and in 1287 the Poles repelled a raid against them. The instability in the Golden Horde seems to have quieted the western front of the Horde. Also, the large scale invasions and raiding that had previously characterized the expansion of the Mongols was cut short probably in some part due to the death of the last great Mongol leader, Tamerlane.

The Hungarians and Poles had responded to the mobile threat by extensive fortification-building, army reform in the form of better-armoured cavalry, and refusing battle unless they could control the site of the battlefield to deny the Mongols local superiority. The Lithuanians relied on their forested homelands for defence and used their cavalry for raiding into Mongol-dominated Russia. When attacking fortresses they would launch dead or diseased animals into fortresses to help spread disease.

Turks

An early Turkic group, the Seljuks, were known for their cavalry archers. These fierce nomads were often raiding empires, such as the Byzantine Empire, and they scored several victories using mobility and timing to defeat the heavy cataphracts of the Byzantines.

One notable victory was at Manzikert, where conflict among the generals of the Byzantines gave the Turks the perfect opportunity to strike. They hit the cataphracts with arrows, and outmanoeuvred them, then rode down their less mobile infantry with light cavalry that used scimitars. When gunpowder was introduced, the Ottoman Turks of the Ottoman Empire hired the mercenaries that used the gunpowder weapons and obtained their instruction for the Janissaries. Out of these Ottoman soldiers rose the Janissaries (yeni ceri; "new soldier"), from which they also recruited many of their heavy infantry. Along with the use of cavalry and early grenades, the Ottomans mounted an offensive in the early Renaissance period and attacked Europe, taking Constantinople by massed infantry assaults.

Like many other nomadic peoples, the Turks featured a core of heavy cavalry from the upper classes. These evolved into the Sipahis (feudal landholders similar to western knights and Byzantine pronoiai) and Qapukulu (door slaves, taken from youth like Janissaries and trained to be royal servants and elite soldiers, mainly cataphracts).

Infantry in the Middle Ages

From Wikipedia, the free encyclopedia
 

Despite the rise of knightly cavalry in the 11th century, infantry played an important role throughout the Middle Ages on both the battlefield and in sieges. From the 14th century onwards, there was a rise in the prominence of infantry forces, sometimes referred to as an "infantry revolution".

Cost and recruitment: the growth of infantry

The rising costs of war

In the medieval period, the mounted warrior held sway for an extended time. Typically heavily armoured, well-motivated and mounted on powerful, specially bred horses, the mounted knight represented a formidable force, which was used to effect against more lightly armoured troops. Since only the noble classes could afford the expense of knightly warfare, the supremacy of the mounted cavalryman was associated with the hierarchical structure of medieval times, particularly feudalism. As the period progressed, however, the dominance of the cavalry elite began to slowly break down. The Black Death in the 14th century swept through Europe, devastating the population and resulting in serious manpower shortages. This encouraged more economical use of available manpower, and the infantryman was much cheaper to outfit and maintain than the aristocratic knight. The Crusade era also saw a rise in the importance of infantry and required large numbers of men and material to be organized for distant battlefields. Such expeditions were part of the growing number of sieges, disputes and campaigns throughout the 13th and 14th centuries that greatly increased the cost of warfare for medieval regimes. The relative inexpensiveness of the infantryman, combined with a shortage of manpower, provided incentives for expanding their use.

Recruitment

By the 11th century, much of the infantry fighting was conducted by high-ranking nobles, middle-class freemen and peasants, who were expected to have a certain standard of equipment, often including helmet, spear, shield and secondary weapons in the form of an axe, long knife or sword. Peasants were also used for the role of archers and skirmishers, providing missile cover for the heavy infantry and cavalry. The later Medieval period also saw the expansion of mercenary forces, unbound to any medieval lord. The Swiss pikeman, the German Landsknecht, and the Italian Condottiere are three of the best known examples of this new class of fighting man. The expanded campaigns, castle-building and sieges of the era also saw greater use of household troops, often bodyguards of the elite, with a variety of useful skills. These were cheaper to recruit and maintain than knights with all their trappings. Siege warfare, in particular, required large bodies of troops in the field, for extended periods, including numerous specialists. All this added up to make the early days of peasant levies unsustainable. As more kings and lords turned to infantry, their opponents had to keep pace, leading to additional increases in foot troops. To obtain the best fighting men, elites had to make provision for their regular payment and supply. As one historian of medieval warfare notes:

The rising importance of foot troops, then, brought not only the opportunity but also the need to expand armies substantially. Then as early as the late 13th century, we can observe Edward I campaigning at the head of armies incorporating tens of thousands of paid archers and spearmen. This represented a major change in approaches to recruitment, organization, and above all pay.

Organisation and deployment

Organization

The importance of good order was well understood in medieval warfare:

Two great evils .... can follow from a disordered formation: one is that enemies can easily break into it; the other is that the formations may be so compressed that they cannot fight. Thus it is important to keep the formation in ranks and tight and joined together like a wall

Militia forces were often organised by guilds or districts, with their officers and banners. Swiss muster rolls show officers and standard bearers being appointed, and men being assigned to particular positions in the formation. Various accounts show that it was the role of commanders to make sure their men knew their position in the formation, knew which banners they fought under and who stood around them.

Infantry formations

Philippe Contamine identifies three basic infantry formations in the Middle Ages; the wall, the circle or crescent and the deep solid formation, either rectangular or triangular.

The wall

Linear formations existed throughout the medieval period. In the early Middle Ages, infantry used the Shieldwall, a formation where shields were held edge-to-edge or overlapped, but lines persisted beyond the widespread abandonment of shields in the later Middle Ages. Lines could vary in depth from four to sixteen deep and were drawn up tightly packed.

The circle

This formation, called the crown by J. F. Verbruggen, was used by infantry to form an all round defence against cavalry. It is recorded as having been used by Flemings, Swiss, Scots and Scandinavians.

Deep formations

Deep columns were favoured by the Swiss. A reconstruction of the deployment of Zürich forces in 1443 gives a formation 56 men wide by 20 deep, the formation having a width of 168 ft. and a depth of 140 ft. The Swiss main formation at the Battle of Morat consisted of 10,000 men, the outer four ranks being made up of pikemen, the inner ranks of halberdiers, the force having an estimated area of 60m. X 60m.

Triangular formations were also used, this sometimes being described as "in the manner of a shield" (L. in modum scuti). Wedge formations were used by the Vikings under the name of a "swine wedge" (ON svinfylking). The Swiss also sometimes used a keil or wedge of pikes to lead their columns.

The nature of infantry combat

Infantry versus cavalry

Tactically there were only two ways for infantry to beat cavalry in an open field battle: firepower and mass. Firepower could be provided by swarms of missiles. Mass could be provided by a tightly packed phalanx of men. Such tactics were long-established; the Romans used missile troops such as slingers, and the core infantry learned to deal with swarming enemy cavalrymen by forming a hollow square fenced with a solid hedge of iron pila (large javelins). Alexander the Great combined both methods in his clashes with the Asiatic horseman of Persia and India, screening his central infantry phalanx with slingers, archers and javelin-men, before unleashing his cavalry against the enemy. Both mass and firepower could be aided by a good tactical position, such as on a hill or on rough terrain, where enemy cavalry would have trouble manoeuvring. These ancient lessons were relearned in the Medieval period: in the Crusades, in the continued operations of forces like the Flemish footman, and particularly the Swiss pikeman and the English longbowman.

The Crusades offer an illustration of the growing recognition of the need for infantry. Against the mounted Islamic foes of European armies, infantry forces were of vital importance. Archers, for example, were essential in holding the fast-moving Muslim cavalry at bay—suppressing their firepower, and allowing the armoured knights to mount successful counter-attacks. Pikemen were important in screening the flanks of the Christian forces, always vulnerable to assault by the Turkish horsemen. Against Saladin's light cavalry at Jaffa (c. 1192) during the Crusades, Richard of England drew up a line of spearmen, kneeling on the ground with spear planted in front, forming an effectual 'hedge of steel' against the charging enemy horsemen. Behind the spear wall, crossbowmen stood ready, with assistants helping to reload. The Muslim armies attacked but the combined firepower of the archers and the steadiness of the wall of spears held. Once the Muslims pulled back, Richard ordered his armoured knights forward, and Saladin withdrew. At the battle of Courtrai in 1302, the determined Flemish infantry staked out a good position on advantageous ground (cut up with streams and ditches) and stood firm against the cavalry charge of the French nobles using their pikes and wooden Goedendag, a combination spear and club. The French charge was stopped and the Flemish infantry then moved forward to liquidate the opposition. At Bannockburn, the Scottish fighters dug numerous pits to foil the English cavalry, blunted the English advance, then counter-attacked with their pike army to soundly defeat their opponents. These and other examples illustrate the importance of trained infantry, but the dominance of the footman did not come overnight. Both cavalryman and infantryman continued to operate for long periods side by side throughout the Medieval period.

Infantry versus infantry

The essential elements of success in infantry combat were seen as good order and a tight formation, not impetus. During the Hundred Years' War, it was considered disadvantageous for infantry to be forced to attack. If infantry were forced to advance to the attack, it should be at a slow, steady pace and without turning. The actual mechanics of impact are not, however, fully understood. In his reconstruction of the infantry fight at Agincourt, John Keegan describes the French as running to contact over the final yards but the English stepping back to "wrong foot" them. The English gave back a "spear's length", leaving the two bodies spear fencing at a distance of 10–15 ft. This idea of a space between the battlelines in which combat takes place also features in some reconstructions of shield wall combat. Others see the clash of shield walls as involving the physical impact of one line with the other.

While it was known for a poorly arrayed line to disintegrate on contact with the enemy, it was more usual for a static battle to ensue and last for some time. Combat was not constant, the two sides parting to rest and reorganise. This could happen several times during combat. When it wasn't possible, an infantry force could become compressed and disordered with disastrous consequences, as happened at Agincourt and Westrozebeke.

The role of archery

The traditional role of archery on the medieval battlefield was to begin the action, advancing in front of the main body of the army, as occurred at the Battle of Hastings. This continued to be a standard tactic, particularly in the absence of enemy cavalry. The Swiss crossbowmen and handgunners of the 15th century were notable for their aggressive skirmishing in advance of the main army, as at Morat. To protect archers, particularly crossbowmen, against enemy archers, they were often deployed behind men with large shields, called pavises. This technique is first noted during the Crusades in the 12th century, for example at Jaffa, but was particularly common in Italy in the later Middle Ages. The crossbow began to replace the standard bow throughout Europe in the 12th century. In England and Wales, the longbow and in the Iberian Peninsula (Portugal and Spain) the recurved bow continued in use to the end of the period. Christian Spain owed the use of composite bows and mounted archery using Parthian shots to its long exposure to Islamic military techniques during the Reconquista.

Later in the Middle Ages, massed archery techniques were developed. English and Welsh longbowmen in particular were famed for the volume and accuracy of their shooting, to which cavalry and poorly armoured infantry were particularly vulnerable.

The role of infantry in sieges

A large number of sieges during the medieval era called for huge numbers of infantry in the field, both in defence and in the attack. Aside from labour units to construct defensive or offensive works, several specialists were deployed such as artillerymen, engineers and miners. Strongly fortified castles were hard to overcome. The simplest, most effective method was blockade and starvation. Artillery in the form of catapult, siege engines and later gunpowder weapons played an important role in reducing fortified positions. Mining beneath walls, shoring up the tunnel then collapsing it was also used. Defenders employed counter-tactics- using their artillery, missile weapons, and countermines against attacking forces. Against sieges, cavalrymen were not as valuable as footmen, and a large number of such troops was also used in the construction of fortifications. Free mercenary forces such as the Condottiere generally attempted to defeat their foes in open field battle or manoeuvre, but also participated in sieges, adding to the specialist ranks that bolstered the growing dominance of infantry.

Notable infantry of the Middle Ages

Swiss pikemen

The use of long pikes and densely packed foot troops was not uncommon during the Middle Ages. The Flemish footmen at the Battle of Courtrai, for example, as shown above, met and overcame the French knights c. 1302, and the Scots occasionally used the technique against the English during the Wars of Scottish Independence. However, it was the Swiss that brought infantry and pike tactics to an extremely high standard.

Morale, mobility and motivation

Rather than reluctant peasant levies dragooned into service by the local lords, the Swiss often fought as volunteer mercenaries for pay throughout Europe. Historical records indicate that the hard-marching Swiss pikemen managed to keep pace with cavalry units at times, if only in the confined terrain of the Alpine regions. Such mobility is outstanding but not unknown among foot soldiers. Roman records mention Germanic infantrymen trotting with cavalry, sometimes resting their hands on the horses for support. Centuries later, the fast-moving Zulu impis in Southern Africa made their mark, reputedly achieving an outstanding march rate of 50 miles per day. Using their mobility, the Swiss were frequently able to overcome contemporary mounted or infantry forces. Swiss pikemen were also generally known as highly motivated, tough-minded soldiers, with little respect for knightly trappings. In several historical accounts, the Swiss refused to retreat and stood and fought to the last man, even when greatly outnumbered, or facing a hopeless outcome.

Weapons and equipment

The Swiss initially started with mid-length polearms such as the halberds and the lucerne hammer, but eventually adopted the pike to fight more effectively in open terrain during the 15th century, after facing difficulties with dismounted gendarmes. These were excellent for dealing with mounted assaults. Rather than simply meet a lance on equal terms, a cavalryman facing the Swiss could expect to deal with sharp points and slashing blows that could certainly not cleave his armour, but could easily break his bones. Some polearms had hooks that could drag an enemy horseman from his mount. Pole weapons were mixed in combat, with pikemen in the front ranks and halberdiers deployed further back to break the deadlock of the "push of pike" after the former had delivered the initial shock treatment. The Swiss wore little armour, unlike the ancient phalanx warriors of old, dispensing with greaves or shield, and donning only a helmet and a relatively light reinforced corselet.

Manoeuvre and formations

In numerous battles before the rise of the Swiss, it was not uncommon for pikemen to group and await a mounted attack. Such an approach is sensible in certain circumstances, particularly if the phalanx occupies a strong position secured by terrain features. The downside is that it allows the attacking force more initiative. At the Battle of Falkirk, the Scots pikemen managed to hold off their cavalry opponents but were caught in a static position, providing targets for the English longbow. The Swiss, though by no means the creators of pike tactics, improved on them by adding flexible formations and aggressive manoeuvre.

When fighting on their own the Swiss often conducted complicated pre-battle manoeuvres through rough terrain to outflank their opponents, the different pike columns attacking from different directions. This was seen at the battles of Grandson, Morat, Nancy, and Novara. On the other hand, when employed in mercenary service they often showed a surprising stubbornness in clinging to frontal assaults (Bicocca, Cerignola), trusting that their reputation for ferocity and unflinching resolve would overcome any opposition.

A typical pike force was divided into three sections or columns. The Swiss were flexible in their dispositions – each section could operate independently or combine with others for mutual support. They could form a hollow square for all-round defence. They could advance in echelon or a triangular "wedge" assault. They could manoeuvre to mount wing attacks – with one column pinning the foe centrally, while a second echelon struck the flanks. They could group in-depth on a strong natural position like a hill. Even more disconcerting to their opponents, the Swiss attacked and manoeuvred aggressively. They did not await the mounted men, but themselves took the initiative, forcing their opponents to respond to their moves. It was a formula that brought them much battlefield success.

The famous Swiss hollow square provided for a vanguard group of blademen using slashing halberds or two-handed swords to break the front of cavalry formations. Bowmen and crossbowmen sometimes preceded the main body also as to provide missile cover, and similar contingents protected the flanks. The main force of pikemen advanced behind this screen. Battle was bloody and direct, and the Swiss killed any opponent regardless of knightly status. At the battle of Murten in 1477, the Swiss demonstrated that the square was not a static formation but could be used aggressively. Deployment of the vanguard, main body and rearguard were staggered in echelon, massing 10,000 men in a very small area (60 by 60 meters). The opposition was liquidated.

Effectiveness of the Swiss

The Swiss won a series of spectacular victories throughout Europe, helping to bring down the feudal order over the time, including victories at Morgarten, Laupen, Sempach, and Grandson. In some engagements the Swiss phalanx included crossbowmen, giving the formation a missile stand-off capability. Such was their effectiveness, that between 1450 and 1550 every leading prince in Europe either hired Swiss pikemen or emulated their tactics and weapons (such as the German Landsknecht). Even the Swiss, however, were not invincible; they could be beaten when confronted with a foe with absolute superiority in numbers, weaponry and armour (as almost happened at Arbedo in 1422, and at St Jakob in 1444) and the advent of firearms and field fortifications made the Swiss frontal steamroller attack extremely risky (as shown by the battles of Cerignola and Bicocca).

English longbowmen

The English longbowman brought new effectiveness to European battlefields, not hitherto known widely for native archery. Also unusual was the type of bow used. Whereas Asian forces typically relied on the powerful multi-piece, multi-layered composite bow, the English relied on the single-piece longbow which delivered a stinging warhead of respectable range and punch.

Longbows and archers

In the British Isles, bows have been known from ancient times, but it was among the tribal Welsh that proficiency in use and construction became highly developed. Using their bows, the Welsh forces inflicted a heavy toll on the English invaders of their lands. Adapted by the English, the longbow was nevertheless a difficult weapon to master, requiring long years of use and practice. Even bow construction was extended, sometimes taking as much as four years for seasoned staves to be prepared and shaped for final deployment. A skilled longbowman could shoot 12 arrows a minute, a rate of fire superior to competing weapons like the crossbow or early gunpowder weapons. The nearest competitor to the longbow was the much more expensive crossbow or Arbalest, used often by urban militias and mercenary forces. It required less training but lacked the range of the longbow. A cheap "low class" weapon, considered "unchivalrous" by those unlucky enough to face it, the longbow outperformed the crossbow in the hands of skilled archers, and was to transform several battlefields in Europe.

The longbow on the battlefield

Longbowmen were used to great effect on the continent of Europe, as assorted kings and leaders clashed with their enemies on the battlefields of France. The most famous of these battles were Crecy, Poitiers and Agincourt. The English tactical system relied on a combination of longbowmen and heavy infantry, such as dismounted men-at-arms. Difficult to deploy in a thrusting mobile offensive, the longbow was best used in a defensive configuration. Against mounted enemies, the bowmen took up a defensive position and unleashed clouds of arrows into the ranks of knights and men-at-arms. The ranks of the bowmen were extended in thin lines and protected and screened by pits (e.g. Crecy), stakes (e.g. Agincourt) or trenches (e.g. Morlaix). There is some academic controversy about how the longbowmen and heavy infantry related on the battlefield. According to the traditional view articulated by A.H. Burne, the bowmen were deployed in a "V" between divisions of infantry, enabling them to trap and enfilade their foes. Other, more recent, historians such as Matthew Bennett dispute this, holding that the archers were normally deployed on the flanks of the army as a whole, rather than between divisions.

The widespread use of the crossbow

While the famous English longbowman is better known in the popular imagination, the missile troops that caused the most damage in the medieval era were the crossbowmen. The Catholic Church tried to outlaw the crossbow and all other ranged weapons at the Second Lateran Council in 1139, without much success. The crossbow was constructed initially of wood with steel gradually taking over in the 15th century, producing a weapon which had a range of 370–500 metres. It shot bolts or quarrels that could pierce most medieval armour. Other advantages of the crossbow were that it required only a few specialists with extensive training and tools to construct while the use of the weapon required little training. The crossbow and the longbow are two different weapon systems with solely their quick succession rate of shot compared in many modern assessments (precision, endurance, exploitation of opportunities are usually not taken into these comparisons). In the Middle Ages, both weapons co-existed, including the use of mounted crossbowmen on the British Islands and longbowmen from the British Isles down to Portugal and Italy. Some crossbows were operated by teams of a shooter with an assistant to help to reload. The assistant could be armed with a spear and a very large shield known as a pavise to provide cover for them. This created one of the typical Medieval mixed structures of crossbowmen and spearmen that were used with great success in the Hussite Wars and by Bertrand du Guesclin in his petty warfare reconquest of France during the Hundred Years' War.

Genoese crossbowmen

The best crossbowmen were considered to be Genoese crossbowmen from Italy, and their counterparts from the Iberian peninsula, such as Barcelona. In Spain crossbowmen were considered in rank equivalent to a cavalryman. The 14th century chronicler Ramon Muntaner believed the Catalans to be the best crossbowmen, because they were capable of maintaining their own weapons.

Crossbow guilds were common in many cities across Europe and crossbow competitions were held. These not only provided a pool of skilled crossbowmen but also reflect the social standing of the crossbowmen. Records of the Guild of St. George in Ghent show an organisation of some sophistication, fielding uniformed crossbowmen organised in companies under officers and standard-bearers, with support services such as pavise carriers (targedragers) and surgeons. Similarly organised co-fraternities of crossbowmen were present in French towns and cities in the 15th. century. Crossbowmen made up a significant proportion of Italian militias in the 13th and 14th century, again organised into units with officers, standards and pavise bearers. In some cities, such as Lucca, they were organised into elite and ordinary classes.

The crossbow on the battlefield

Crossbowmen generally opened a battle by skirmishing ahead of the army, as at the Battle of Courtrai, or were placed to cover the flanks, as at the Battle of Campaldino.

Infantry and the Medieval military revolution

Ayton and Price identify three components to the so-called "military revolution" occurring at the end of the Middle Ages; a rise in the importance of infantry to the detriment of heavy cavalry, increasing use of gunpowder weapons on the battlefield and sieges, as well as social, political, and fiscal changes allowing the growth of larger armies. The first of these components to manifest itself as the "infantry revolution", which developed during the 14th century. Initial victories like Courtrai or Morgarten were strongly dependent on use of terrain but over the course of the century two effective infantry systems developed; the infantry block, armed with spears and polearms, epitomised by the Swiss and the practice of combining dismounted men-at-arms with infantry with ranged weapons, typified by the English longbowman.

It would be wrong to assume that the infantry revolution swept heavy cavalry from the field. Improvements in armour for man and horse allowed cavalry to retain an important role into the 16th century. Instead, the three components of revolution identified by Ayton and Price led to a rebalancing of the elements of the medieval tactical system, opening the way for an integrated arms approach in the 16th century.
