The first evidence ofhorses inwarfare dates fromEurasia between 4000 and 3000 BC. ASumerian illustration of warfare from 2500 BC depicts some type ofequinepulling wagons. By 1600 BC, improvedharness andchariot designs made chariot warfare common throughout theAncient Near East, and the earliest written training manual for war horses was a guide for training chariot horses written about 1350 BC. As formalcavalry tactics replaced the chariot, so did new training methods, and by 360 BC, the Greek cavalry officerXenophon had written an extensive treatise on horsemanship. The effectiveness of horses in battle was also revolutionized by improvements intechnology, such as the invention of thesaddle, thestirrup, and thehorse collar.
Many different types and sizes of horses were used in war, depending on the form of warfare. The type used varied with whether the horse was being ridden or driven, and whether they were being used forreconnaissance, cavalry charges,raiding, communication, or supply. Throughout history,mules anddonkeys, as well as horses played a crucial role in providing support to armies in the field.
Horses were well suited to the warfare tactics of thenomadic cultures from thesteppes ofEastern Europe andCentral Asia. Several cultures inEast Asia made extensive use of cavalry and chariots.Muslim warriors relied uponlight cavalry in their campaigns throughoutNorthern Africa,Asia, andEurope beginning in the 7th and 8th centuries AD. Europeans used several types of war horses in theMiddle Ages, and the best-knownheavy cavalry warrior of the period was the armouredknight. With the decline of the knight and rise of gunpowder in warfare, light cavalry again rose to prominence, used in both European warfare and in the conquest of theAmericas. Battle cavalry developed to take on a multitude of roles in the late 18th century and early 19th century and was often crucial for victory in theNapoleonic Wars. In the Americas, the use of horses and development of mounted warfare tactics were learned by several tribes ofindigenous people and in turn, highly mobile horse regiments were critical in theAmerican Civil War.
Horse cavalry began to be phased out afterWorld War I in favour oftank warfare, though a few horse cavalry units were still used intoWorld War II, especially as scouts. By the end of World War II, horses were seldom seen in battle, but were still used extensively for the transport of troops and supplies. Today, formal battle-ready horse cavalry units have almost disappeared, though theUnited States Army Special Forces used horses in battle during the2001 invasion of Afghanistan. Horses are still seen in use by organized armed fighters in theGlobal South. Many nations still maintain small units of mounted riders for patrol andreconnaissance, and military horse units are also used for ceremonial and educational purposes. Horses are also used forhistorical reenactment of battles,law enforcement, and inequestrian competitions derived from the riding and training skills once used by the military.
A fundamental principle ofequine conformation is "form to function". Therefore, the type of horse used for various forms of warfare depended on the work performed, the weight a horse needed to carry or pull, and distance travelled.[1] Weight affects speed and endurance, creating a trade-off: armour added protection,[2] but added weight reduced maximum speed.[3] Therefore, various cultures had different military needs. In some situations, one primary type of horse was favoured over all others.[4] In other places, multiple types were needed; warriors would travel to battle riding a lighter horse of greater speed and endurance, and then switch to a heavier horse, with greater weight-carrying capacity, when wearing heavy armour in actual combat.[5]
The average horse can carry up to approximately 30% of its body weight.[6] While all horses can pull more weight than they can carry, the maximum weight that horses can pull varies widely, depending on the build of the horse, the type of vehicle, road conditions, and other factors.[7][8][9] Horsesharnessed to a wheeled vehicle on a paved road can pull as much as eight times their weight,[10] but far less if pulling wheelless loads over unpaved terrain.[11][12] Thus, horses that weredriven varied in size and had to make a trade-off between speed and weight, just as did riding animals. Light horses could pull a small war chariot at speed.[13] Heavy supply wagons,artillery, and support vehicles were pulled by heavier horses or a larger number of horses.[14] The method by which a horse was hitched to a vehicle also mattered: horses could pull greater weight with ahorse collar than they could with abreast collar, and even less with an oxyoke.[15]
Light,oriental horses such as the ancestors of the modernArabian,Barb, andAkhal-Teke were used for warfare that required speed, endurance, and agility.[16] Such horses ranged from about 12 hands (48 inches, 122 cm) to just under 15 hands (60 inches, 152 cm), weighing approximately 360 to 450 kilograms (800 to 1,000 lb).[17] To move quickly, riders had to use lightweighttack and carry relatively light weapons such as bows, light spears, javelins, or later rifles. This was the original horse used for early chariot warfare, raiding, and lightcavalry.[18]
Relatively light horses were used by many cultures, including theAncient Egyptians,[19] theMongols, theArabs,[20] and theNative Americans. Throughout theAncient Near East, small, light animals were used to pull chariots designed to carry no more than two passengers, a driver and a warrior.[21][22] In the EuropeanMiddle Ages, a lightweight war horse became known as therouncey.[23]
Medium-weight horses developed as early as theIron Age with the needs of various civilizations to pull heavier loads, such as chariots capable of holding more than two people,[22] and, aslight cavalry evolved intoheavy cavalry, to carry heavily armoured riders.[24] TheScythians were among the earliest cultures to produce taller, heavier horses.[25] Larger horses were also needed to pull supply wagons and, later on, artillery pieces. In Europe, horses were also used to a limited extent to maneuvercannons on the battlefield as part of dedicatedhorse artillery units. Medium-weight horses had the greatest range in size, from about 14.2 hands (58 inches, 147 cm) but stocky,[24][26] to as much as 16 hands (64 inches, 163 cm),[27] weighing approximately 450 to 540 kilograms (1,000 to 1,200 lb). They generally were quite agile in combat,[28] though they did not have the raw speed or endurance of a lighter horse. By theMiddle Ages, larger horses in this class were sometimes calleddestriers. They may have resembled modernBaroque orheavy warmblood breeds.[note 1] Later, horses similar to the modernwarmblood often carried European cavalry.[30]
Large, heavy horses, weighing from 680 to 910 kilograms (1,500 to 2,000 lb), the ancestors of today'sdraught horses, were used, particularly in Europe, from theMiddle Ages onward. They pulled heavy loads like supply wagons and were disposed to remain calm in battle. Some historians believe they may have carried the heaviest-armouredknights of theLate Medieval Period, though others dispute this claim, indicating that the destrier, or knight's battle horse, was a medium-weight animal. It is also disputed whether the destrier class included draught animals or not.[31] Breeds at the smaller end of the heavyweight category may have included the ancestors of thePercheron, agile for their size and physically able to maneuver in battle.[32]
The British Army's 2nd Dragoons in 1813 had 340 ponies of 14.2 hands (58 inches, 147 cm) and 55 ponies of 14 hands (56 inches, 142 cm);[33] the Lovat Scouts, formed in 1899, were mounted on Highland ponies;[34] the British Army recruited 200 Dales ponies in World War II for use as pack and artillery animals;[35] and the British Territorial Army experimented with the use of Dartmoor ponies aspack animals in 1935, finding them to be better than mules for the job.[36]

Horses were not the onlyequids used to support human warfare.Donkeys have been used as pack animals from antiquity[37] to the present.[38]Mules were also commonly used, especially as pack animals and to pull wagons, but also occasionally for riding.[39] Because mules are often both calmer and hardier than horses,[40] they were particularly useful for strenuous support tasks, such as hauling supplies over difficult terrain. However, under gunfire, they were less cooperative than horses, so were generally not used to haulartillery on battlefields.[8] The size of a mule and work to which it was put depended largely on the breeding of themare that produced the mule. Mules could be lightweight, medium weight, or even, when produced from draught horsemares, of moderate heavy weight.[41]
The oldest known manual on training horses for chariot warfare was written c. 1350 BC by theHittite horsemaster,Kikkuli.[42] An ancient manual on the subject of training riding horses, particularly for theAncient Greek cavalry isHippike (On Horsemanship) written about 360 BC by the Greek cavalry officerXenophon.[43] and another early text was that ofKautilya, written about 323 BC.[42]
Whether horses were trained to pull chariots, to be ridden as light or heavy cavalry, or to carry the armoured knight, much training was required to overcome the horse's natural instinct to flee from noise, the smell of blood, and the confusion of combat. They also learned to accept any sudden or unusual movements of humans while using a weapon or avoiding one.[44] Horses used in close combat may have been taught, or at least permitted, to kick, strike, and even bite, thus becoming weapons themselves for the warriors they carried.[45]
In most cultures, a war horse used as a riding animal was trained to be controlled with limited use ofreins, responding primarily to the rider'slegs and weight.[46] The horse became accustomed to any necessarytack and protective armour placed upon it, and learned to balance under a rider who would also be laden with weapons and armour.[44] Developing the balance and agility of the horse was crucial. The origins of the discipline ofdressage came from the need to train horses to be both obedient and manoeuvrable.[30] TheHaute ecole or "High School" movements ofclassical dressage taught today at theSpanish Riding School have their roots in manoeuvres designed for the battlefield. However, theairs above the ground were unlikely to have been used in actual combat, as most would have exposed the unprotected underbelly of the horse to the weapons of foot soldiers.[47]
Horses used forchariot warfare were not only trained for combat conditions, but because many chariots were pulled by a team of two to four horses, they also had to learn to work together with other animals in close quarters under chaotic conditions.[48]
Horses were probably ridden in prehistory before they were driven. However, evidence is scant, mostly simple images of human figures on horse-like animals drawn on rock or clay.[49][50] The earliest tools used to control horses werebridles of various sorts, which were invented nearly as soon as the horse wasdomesticated.[51] Evidence ofbit wear appears on the teeth of horses excavated at the archaeology sites of theBotai culture in northernKazakhstan, dated 3500–3000 BC.[52]
The invention of the wheel was a major technological innovation that gave rise tochariot warfare. At first, equines, both horses andonagers, were hitched to wheeled carts by means of ayoke around their necks in a manner similar to that ofoxen.[53] However, such a design is incompatible withequine anatomy, limiting both the strength and mobility of the animal. By the time of theHyksos invasions ofEgypt, c. 1600 BC, horses were pulling chariots with an improvedharness design that made use of abreastcollar andbreeching, which allowed a horse to move faster and pull more weight.[54]
Even after the chariot had become obsolete as a tool of war, there still was a need for technological innovations in pulling technologies; horses were needed to pull heavy loads of supplies and weapons. The invention of thehorse collar in China during the 5th century AD (Northern and Southern dynasties) allowed horses to pull greater weight than they could when hitched to a vehicle with the ox yokes or breast collars used in earlier times.[55] The horse collar arrived in Europe during the 9th century,[56] and became widespread by the 12th century.[57]
Two major innovations that revolutionised the effectiveness of mounted warriors in battle were the saddle and the stirrup.[58] Riders quickly learned to pad their horse's backs to protect themselves from the horse's spine andwithers, and fought on horseback for centuries with little more than a blanket or pad on the horse's back and a rudimentary bridle. To help distribute the rider's weight and protect the horse's back, some cultures created stuffed padding that resembles the panels of today'sEnglish saddle.[59] Both theScythians andAssyrians used pads with added felt attached with asurcingle orgirth around the horse'sbarrel for increased security and comfort.[60] Xenophon mentioned the use of a padded cloth on cavalry mounts as early as the 4th century BC.[43]
The saddle with a solid framework, or "tree", provided a bearing surface to protect the horse from the weight of the rider, but was not widespread until the 2nd century AD.[43] However, it made a critical difference, as horses could carry more weight when distributed across a solid saddle tree. A solid tree, the predecessor of today'sWestern saddle, also allowed a more built-up seat to give the rider greater security in the saddle. TheRomans are credited with the invention of the solid-treed saddle.[61]
An invention that made cavalry particularly effective was the stirrup. A toe loop that held the big toe was used in India possibly as early as 500 BC,[62] and later a single stirrup was used as a mounting aid. The first set of paired stirrups appeared in China about 322 AD during theJin dynasty.[63][64] Following the invention of paired stirrups, which allowed a rider greater leverage with weapons, as well as both increased stability and mobility while mounted, nomadic groups such as theMongols adopted this technology and developed a decisive military advantage.[62] By the 7th century, due primarily to invaders from Central Asia, stirrup technology spread from Asia to Europe.[65] TheAvar invaders are viewed as primarily responsible for spreading the use of the stirrup into central Europe.[66][67] However, while stirrups were known in Europe in the 8th century, pictorial and literary references to their use date only from the 9th century.[68] Widespread use in Northern Europe, including England, is credited to theVikings, who spread the stirrup in the 9th and 10th centuries to those areas.[68][69][70]
The firstarchaeological evidence of horses used in warfare dates from between 4000 and 3000 BC in thesteppes ofEurasia, in what today isUkraine,Hungary, andRomania. Not long afterdomestication of the horse, people in these locations began to live together in large fortified towns for protection from the threat of horseback-riding raiders,[61] who could attack and escape faster than people of more sedentary cultures could follow.[71][72] Horse-mounted nomads of thesteppe and current dayEastern Europe spreadIndo-European Languages as they conquered other tribes and groups.[73]
The use of horses in organised warfare was documented early in recorded history. One of the first depictions is the "war panel" of theStandard of Ur, inSumer, dated c. 2500 BC, showing horses (or possibly onagers or mules) pulling a four-wheeled wagon.[53]
Among the earliest evidence of chariot use are the burials of horse and chariot remains by theAndronovo (Sintashta-Petrovka) culture in modern Russia andKazakhstan, dated to approximately 2000 BC.[74] The oldest documentary evidence of what was probably chariot warfare in theAncient Near East is the Old HittiteAnitta text, of the 18th century BC, which mentioned 40 teams of horses at the siege ofSalatiwara.[75] TheHittites became well known throughout the ancient world for their prowess with the chariot. Widespread use of the chariot in warfare across most of Eurasia coincides approximately with the development of thecomposite bow, known from c. 1600 BC. Further improvements in wheels and axles, as well as innovations in weaponry, soon resulted in chariots being driven in battle byBronze Age societies from China to Egypt.[52]
TheHyksos invaders brought the chariot toAncient Egypt in the 16th century BC and the Egyptians adopted its use from that time forward.[76][77][78] The oldest preserved text related to the handling of war horses in the ancient world is the Hittite manual ofKikkuli, which dates to about 1350 BC, and describes the conditioning of chariot horses.[42][79]
Chariots existed in theMinoan civilization, as they were inventoried on storage lists fromKnossos inCrete,[80] dating to around 1450 BC.[81] Chariots were also used in China as far back as theShang dynasty (c. 1600–1050 BC), where they appear in burials. The high point of chariot use in China was in theSpring and Autumn period (770–476 BC), although they continued in use up until the 2nd century BC.[82]
Descriptions of the tactical role of chariots inAncient Greece andRome are rare. TheIliad, possibly referring toMycenaen practices used c. 1250 BC, describes the use of chariots for transporting warriors to and from battle, rather than for actual fighting.[80][83] Later,Julius Caesar, invading Britain in 55 and 54 BC, noted British charioteers throwing javelins, then leaving their chariots to fight on foot.[84][85]
Some of the earliest examples of horses being ridden in warfare werehorse-mounted archers or javelin-throwers, dating to the reigns of theAssyrian rulersAshurnasirpal II andShalmaneser III.[50] However, these riders sat far back on their horses, a precarious position for moving quickly, and the horses were held by a handler on the ground, keeping the archer free to use the bow. Thus, these archers were more a type ofmounted infantry than true cavalry.[43] The Assyrians developedcavalry in response to invasions by nomadic people from the north, such as theCimmerians, who enteredAsia Minor in the 8th century BC and took over parts ofUrartu during the reign ofSargon II, approximately 721 BC.[86] Mounted warriors such as theScythians also had an influence on the region in the 7th century BC.[60] By the reign ofAshurbanipal in 669 BC, the Assyrians had learned to sit forward on their horses in the classic riding position still seen today and could be said to be truelight cavalry.[43] Theancient Greeks used both light horse scouts and heavy cavalry,[43][50] although not extensively, possibly due to the cost of keeping horses.[80]
Heavy cavalry was believed to have been developed by the AncientPersians,[50] although others argue for theSarmatians.[87] By the time ofDarius (558–486 BC), Persian military tactics required horses and riders that were completely armoured, andselectively bred a heavier, more muscled horse to carry the additional weight.[24] Thecataphract was a type of heavily armoured cavalry with distinct tactics, armour, and weaponry used from the time of the Persians up until the Middle Ages.[88]
InAncient Greece,Phillip of Macedon is credited with developing tactics allowing massed cavalry charges.[89] The most famous Greek heavy cavalry units were thecompanion cavalry ofAlexander the Great.[90] The Chinese of the 4th century BC during theWarring States period (403–221 BC) began to use cavalry against rival states.[91] To fight nomadic raiders from the north and west, the Chinese of theHan dynasty (202 BC – 220 AD) developed effective mounted units.[92] Cavalry was not used extensively by theRomans during theRoman Republic period, but by the time of theRoman Empire, they made use of heavy cavalry.[93][94] However, the backbone of the Roman army was the infantry.[95]
Once gunpowder was invented, another major use of horses was asdraught animals forheavy artillery, orcannon. In addition tofield artillery, where horse-drawn guns were attended by gunners on foot, many armies hadartillery batteries where each gunner was provided with a mount.[96] Horse artillery units generally used lighter pieces, pulled by six horses. "9-pounders" were pulled by eight horses, and heavier artillery pieces needed a team of twelve. With the individual riding horses required for officers, surgeons and other support staff, as well as those pulling the artillery guns and supply wagons, an artillery battery of six guns could require 160 to 200 horses.[97] Horse artillery usually came under the command of cavalry divisions, but in some battles, such asWaterloo, the horse artillery were used as a rapid response force, repulsing attacks and assisting the infantry.[98] Agility was important; the ideal artillery horse was 1.5 to 1.6 metres (15 to 16hands) high, strongly built, but able to move quickly.[8]

Relations betweensteppe nomads and the settled people in and aroundCentral Asia were often marked by conflict.[100][101] The nomadic lifestyle was well suited to warfare, and steppe cavalry became some of the most militarily potent forces in the world, only limited by nomads' frequent lack of internal unity. Periodically, strong leaders would organise several tribes into one force, creating an almost unstoppable power.[102][103] These unified groups included theHuns, who invaded Europe,[104] and underAttila, conducted campaigns in both eastern France and northern Italy, over 500 miles apart, within two successive campaign seasons.[72] Other unified nomadic forces included theWu Hu rebellions in China,[105] and theMongol conquest of much of Eurasia.[106]
The literature of ancientIndia describes numerous horse nomads. Some of the earliest references to the use of horses in South Asian warfare arePuranic texts, which refer to an attempted invasion of India by the joint cavalry forces of theSakas,Kambojas,Yavanas,Pahlavas, andParadas, called the "five hordes" (pañca.ganah) or "Kśatriya" hordes (Kśatriya ganah). About 1600 BC, they captured the throne ofAyodhya by dethroning theVedic king, Bahu.[107] Later texts, such as theMahābhārata, c. 950 BC, appear to recognise efforts taken tobreed war horses and develop trained mounted warriors, stating that the horses of theSindhu and Kamboja regions were of the finest quality, and the Kambojas, Gandharas, and Yavanas were expert in fighting from horses.[108][109][110]
In technological innovation, the early toe loop stirrup is credited to the cultures of India, and may have been in use as early as 500 BC.[62] Not long after, the cultures ofMesopotamia andAncient Greece clashed with those of central Asia and India.Herodotus (484–425 BC) wrote thatGandarian mercenaries of theAchaemenid Empire were recruited into the army of emperorXerxes I of Persia (486–465 BC), which he led against the Greeks.[111] A century later, the "Men of the Mountain Land," from north ofKabul River,[note 2] served in the army ofDarius III of Persia when he fought againstAlexander the Great atArbela in 331 BC.[112] In battle against Alexander at Massaga in 326 BC, the Assakenoi forces included 20,000 cavalry.[113] TheMudra-Rakshasa recounted how cavalry of the Shakas, Yavanas, Kambojas,Kiratas,Parasikas, andBahlikas helpedChandragupta Maurya (c. 320–298 BC) defeat the ruler ofMagadha and take the throne, thus laying the foundations ofMauryan dynasty in Northern India.[114]
Mughal cavalry used gunpowder weapons, but were slow to replace the traditional composite bow.[115] Under the impact of European military successes in India, some Indian rulers adopted the European system of massed cavalry charges, although others did not.[116] By the 18th century, Indian armies continued to field cavalry, but mainly of the heavy variety.
The Chinese usedchariots for horse-based warfare until light cavalry forces became common during theWarring States era (402–221 BC). A major proponent of the change to riding horses from chariots wasWu Ling, c. 320 BC. However, conservative forces in China often opposed change, as cavalry did not benefit from the additional cachet attached to being the military branch dominated by the nobility as in medieval Europe.[117] Nevertheless, during the reign ofEmperor Wu of Han (r. 141–87 BC), it is recorded that 300,000government-owned horses were insufficient for the cavalry andbaggage trains of theHan military inthe campaigns to expel theXiongnu nomads from theOrdos Desert,Qilian Mountains,Khangai Mountains andGobi Desert, spurring new policies that encouraged households to hand over privately-bred horses in exchange for military and corvee labor exemptions.[118]
The Japanesesamurai fought as cavalry for many centuries.[119] They were particularly skilled in the art of using archery from horseback. The archery skills of mounted samurai were developed by training such asYabusame, which originated in 530 AD and reached its peak underMinamoto no Yoritomo (1147–1199 AD) in theKamakura period.[120] They switched from an emphasis onmounted bowmen to mounted spearmen during theSengoku period (1467–1615 AD).
During the period when variousIslamic empires controlled much of theMiddle East as well as parts ofWest Africa and theIberian peninsula,Muslim armies consisted mostly of cavalry, made up of fighters from various local groups,mercenaries andTurkoman tribesmen. The latter were considered particularly skilled as bothlancers andarchers from horseback. In the 9th century the use ofMamluks, slaves raised to be soldiers for various Muslim rulers, became increasingly common.[121] Mobile tactics, advancedbreeding of horses, and detailed training manuals made Mamluk cavalry a highly efficient fighting force.[122] The use of armies consisting mostly of cavalry continued among the Turkish people who founded theOttoman Empire. Their need for large mounted forces led to an establishment of thesipahi, cavalry soldiers who were granted lands in exchange for providingmilitary service in times of war.[123]
Mounted Muslim warriors conquered North Africa and theIberian Peninsula during the 7th and 8th centuries AD following theHijrah, ofMuhammad in 622 AD. By 630 AD, their influence expanded across theMiddle East and into westernNorth Africa. By 711 AD, the light cavalry of Muslim warriors had reached Spain, and controlled most of the Iberian peninsula by 720.[124] Their mounts were of various oriental types, including the North AfricanBarb. A fewArabian horses may have come with theUmmayads who settled in theGuadalquivir valley. Another strain of horse that came with Islamic invaders was theTurkoman horse.[125] Muslim invaders travelled north from present-day Spain into France, where they were defeated by theFrankish rulerCharles Martel at theBattle of Tours in 732 AD.[126]
During the EuropeanMiddle Ages, there were three primary types of war horses: thedestrier, thecourser, and therouncey, which differed in size and usage. A generic word used to describe medieval war horses wascharger, which appears interchangeable with the other terms.[127] The medieval war horse was of moderate size, rarely exceeding 15.2 hands (62 inches, 157 cm). Heavy horses were logistically difficult to maintain and less adaptable to varied terrains.[128] The destrier of theearly Middle Ages was moderately larger than the courser or rouncey, in part to accommodate heavier armouredknights.[129] However, destriers were not as large asdraught horses, averaging between 14.2 hands (58 inches, 147 cm) and 15 hands (60 inches, 152 cm).[26] On the European continent, the need to carry more armour against mounted enemies such as theLombards andFrisians led to theFranks developing heavier, bigger horses.[130] As the amount of armour and equipment increased in the later Middle Ages, the height of the horses increased; some late medieval horse skeletons were of horses over 1.5 metres (15hands).[129]
Stallions were often used as destriers due to their natural aggression.[131] However, there may have been some use ofmares by European warriors,[131] and mares, who were quieter and less likely to call out and betray their position to the enemy, were the preferred war horse of theMoors, who invaded various parts of Southern Europe from 700 AD through the 15th century.[132]Geldings were used in war by theTeutonic Knights, and known as "monk horses" (German:Mönchpferde orMönchhengste). One advantage was if captured by the enemy, they could not be used to improve local bloodstock, thus maintaining the Knights' superiority in horseflesh.[133]
The heavy cavalry charge, while it could be effective, was not a common occurrence.[134] Battles were rarely fought on land suitable for heavy cavalry. While mounted riders remained effective for initial attacks,[135] by the end of the 14th century, it was common for knights to dismount to fight,[136] while their horses were sent to the rear, kept ready for pursuit.[137]Pitched battles were avoided if possible, with most offensivewarfare in the early Middle Ages taking the form ofsieges,[138] and in the later Middle Ages as mounted raids calledchevauchées, with lightly armed warriors on swift horses.[note 3]
The war horse was also seen inhastiludes – martial war games such as thejoust, which began in the 11th century both as sport and to provide training for battle.[141] Specialised destriers were bred for the purpose,[142] although the expense of keeping, training, and outfitting them kept the majority of the population from owning one.[143] While some historians suggest that the tournament had become a theatrical event by the 15th and 16th centuries, others argue thatjousting continued to help cavalry train for battle until theThirty Years' War.[144]
The decline of the armoured knight was probably linked to changing structures of armies and various economic factors, and not obsolescence due to new technologies. However, some historians attribute the demise of the knight to the invention ofgunpowder,[145] or to theEnglish longbow.[146] Some link the decline to both technologies.[147] Others argue these technologies actually contributed to the development of knights:plate armour was first developed to resist early medievalcrossbow bolts,[148] and the full harness worn by the early 15th century developed to resist longbow arrows.[149] From the 14th century onwards, most plate was made from hardened steel, which resisted early musket ammunition.[148] In addition, stronger designs did not make plate heavier; a full harness of musket-proof plate from the 17th century weighed 70 pounds (32 kg), significantly less than 16th century tournament armour.[150]
The move to predominately infantry-based battles from 1300 to 1550 was linked to both improvedinfantry tactics and changes inweaponry.[151] By the 16th century, the concept of a combined-arms professional army had spread throughout Europe.[149] Professional armies emphasized training, and were paid via contracts, a change from the ransom and pillaging which reimbursed knights in the past. When coupled with the rising costs involved in outfitting and maintaining armour and horses, the traditional knightly classes began to abandon their profession.[152] Light horses, orprickers, were still used for scouting and reconnaissance; they also provided a defensive screen for marching armies.[137] Large teams of draught horses oroxen pulled the heavy earlycannon.[153] Other horses pulled wagons and carried supplies for the armies.
During theearly modern period the shift continued from heavy cavalry and the armoured knight to unarmouredlight cavalry, includingHussars andChasseurs à cheval.[154] Light cavalry facilitated better communication, using fast, agile horses to move quickly across battlefields.[155] The ratio of footmen to horsemen also increased over the period as infantry weapons improved and footmen became more mobile and versatile, particularly once the musketbayonet replaced the more cumbersome pike.[156] During theElizabethan era, mounted units includedcuirassiers, heavily armoured and equipped with lances; light cavalry, who wore mail and bore light lances and pistols; and "petronels", who carried an earlycarbine.[157] As heavy cavalry use declined armour was increasingly abandoned anddragoons, whose horses were rarely used in combat, became more common:mounted infantry provided reconnaissance, escort and security.[157] However, many generals still used the heavy mounted charge, from the late 17th century and early 18th century, where sword-wielding wedge-formation shock troops penetrated enemy lines,[158] to the early 19th century, where armoured heavy cuirassiers were employed.[159]
Light cavalry continued to play a major role, particularly after theSeven Years' War when Hussars started to play a larger part in battles.[160] Though some leaders preferred tall horses for their mounted troops this was as much for prestige as for increased shock ability and many troops used more typical horses, averaging 15 hands.[128] Cavalry tactics altered with fewer mounted charges, more reliance on drilled maneuvers at thetrot, and use of firearms once within range.[161] Ever-more elaborate movements, such as wheeling andcaracole, were developed to facilitate the use of firearms from horseback. These tactics were not greatly successful in battle sincepikemen protected bymusketeers could deny cavalry room to manoeuvre. However the advancedequestrianism required survives into the modern world asdressage.[162][163] While restricted, cavalry was not rendered obsolete. As infantry formations developed in tactics and skills, artillery became essential to break formations; in turn, cavalry was required to both combat enemy artillery, which was susceptible to cavalry while deploying, and to charge enemy infantry formations broken by artillery fire. Thus, successful warfare depended in a balance of the three arms: cavalry, artillery and infantry.[164]
As regimental structures developed many units selected horses of uniform type and some, such as theRoyal Scots Greys, even specified colour. Trumpeters often rode distinctive horses so they stood out. Regional armies developed type preferences, such as Britishhunters,Hanoverians in central Europe, andsteppe ponies of theCossacks, but once in the field, the lack of supplies typical of wartime meant that horses of all types were used.[165] Since horses were such a vital component of most armies in early modern Europe, many institutedstate stud farms to breed horses for the military. However, in wartime, supply rarely matched the demand, resulting in some cavalry troops fighting on foot.[128]
In the 19th century distinctions between heavy and light cavalry became less significant; by the end of thePeninsular War, heavy cavalry were performing the scouting and outpost duties previously undertaken by light cavalry, and by the end of the 19th century the roles had effectively merged.[166] Most armies at the time preferred cavalry horses to stand 15.2 hands (62 inches, 157 cm) and weigh 990 to 1,100 pounds (450 to 500 kg), althoughcuirassiers frequently had heavier horses. Lighter horses were used for scouting and raiding. Cavalry horses were generally obtained at 5 years of age and were in service from 10 to 12 years, barring loss. However losses of 30–40% were common during a campaign due to conditions of the march as well as enemy action.[167] Mares andgeldings were preferred over less-easily managed stallions.[168]
During theFrench Revolutionary Wars and theNapoleonic Wars the cavalry's main offensive role was as shock troops. In defence cavalry were used to attack and harass the enemy's infantry flanks as they advanced. Cavalry were frequently used prior to an infantry assault, to force an infantry line to break and reform into formations vulnerable to infantry or artillery.[169] Infantry frequently followed behind in order to secure any ground won[170] or the cavalry could be used to break up enemy lines following a successful infantry action.
Mounted charges were carefully managed. A charge's maximum speed was 20 km/h; moving faster resulted in a break in formation and fatigued horses. Charges occurred across clear rising ground, and were effective against infantry both on the march and when deployed in aline orcolumn.[171] A footbattalion formed in line was vulnerable to cavalry, and could be broken or destroyed by a well-formed charge.[172] Traditional cavalry functions altered by the end of the 19th century. Many cavalry units transferred in title and role to "mounted rifles": troops trained to fight on foot, but retaining mounts for rapid deployment, as well as for patrols, scouting, communications, and defensive screening. These troops differed frommounted infantry, who used horses for transport but did not perform the old cavalry roles of reconnaissance and support.[173]
Horses were used for warfare in the centralSudan since the 9th century, where they were considered "the most precious commodity following the slave."[174] The first conclusive evidence of horses playing a major role in the warfare ofWest Africa dates to the 11th century when the region was controlled by theAlmoravids, a MuslimBerber dynasty.[175] During the 13th and 14th centuries, cavalry became an important factor in the area. This coincided with the introduction of larger breeds of horse and the widespread adoption of saddles and stirrups.[176] Increased mobility played a part in the formation of new power centers, such as theOyo Empire in what today isNigeria. The authority of many African Islamic states such as theBornu Empire also rested in large part on their ability to subject neighboring peoples with cavalry.[177] Despite harsh climate conditions, endemic diseases such astrypanosomiasis, theAfrican horse sickness, and unsuitable terrain that limited the effectiveness of horses in many parts of Africa, horses were continuously imported and were, in some areas, a vital instrument of war.[178] The introduction of horses also intensified existing conflicts, such as those between theHerero andNama people in Namibia during the 19th century.[179]
The African slave trade was closely tied to the imports of war horses, and as the prevalence of slaving decreased, fewer horses were needed for raiding. This significantly decreased the amount of mounted warfare seen in West Africa.[180] By the time of theScramble for Africa and the introduction of modern firearms in the 1880s, the use of horses in African warfare had lost most of its effectiveness.[180] Nonetheless, inSouth Africa during theSecond Boer War (1899–1902), cavalry and other mounted troops were the major combat force for the British, since the horse-mounted Boers moved too quickly for infantry to engage.[181] The Boers presented a mobile and innovative approach to warfare, drawing on strategies that had first appeared in theAmerican Civil War.[182] The terrain was not well-suited to the British horses, resulting in the loss of over 300,000 animals. As the campaign wore on, losses were replaced by more durable AfricanBasuto ponies, andWaler horses fromAustralia.[128]
The horse had been extinct in theWestern Hemisphere for approximately 10,000 years prior to the arrival of SpanishConquistadors in the early 16th century. Consequently, theIndigenous peoples of the Americas had no warfare technologies that could overcome the considerable advantage provided by European horses and gunpowder weapons. In particular this resulted in the conquest of theAztec andInca empires.[183] The speed and increased impact of cavalry contributed to a number of early victories by European fighters in open terrain, though their success was limited in more mountainous regions.[184] The Incas' well-maintained roads in theAndes enabled quick mounted raids, such as those undertaken by the Spanish while resisting thesiege of Cuzco in 1536–37.[184]
Indigenous populations of South America soon learned to use horses. In Chile, theMapuche began using cavalry in theArauco War in 1586. They drove the Spanish out ofAraucanía at the beginning of the 17th century. Later, the Mapuche conducted mounted raids known asMalónes, first on Spanish, then on Chilean and Argentine settlements until well into the 19th century.[185] In North America,Native Americans also quickly learned to use horses. In particular, the people of theGreat Plains, such as theComanche and theCheyenne, became renowned horseback fighters. By the 19th century, they presented a formidable force against theUnited States Army.[186]
During theAmerican Revolutionary War (1775–1783), theContinental Army made relatively little use of cavalry, primarily relying on infantry and a few dragoon regiments.[187] TheUnited States Congress eventually authorized regiments specifically designated as cavalry in 1855. The newly formed American cavalry adopted tactics based on experiences fighting over vast distances during theMexican War (1846–1848) and against indigenous peoples on the western frontier, abandoning some European traditions.[188]
During theAmerican Civil War (1861–1865), cavalry held the most important and respected role it would ever hold in the American military.[188][note 4]Field artillery in the American Civil War was also highly mobile. Both horses and mules pulled the guns, though only horses were used on the battlefield.[8] At the beginning of the war, most of the experienced cavalry officers were from the South and thus joined theConfederacy, leading to theConfederate Army's initial battlefield superiority.[188] The tide turned at the 1863Battle of Brandy Station, part of theGettysburg campaign, where theUnion cavalry, in the largest cavalry battle ever fought on the American continent,[note 5] ended the dominance of the South.[190] By 1865, Union cavalry were decisive in achieving victory.[188] So important werehorses to individual soldiers that the surrender terms atAppomattox allowed every Confederate cavalryman to take his horse home with him. This was because, unlike their Union counterparts, Confederate cavalrymen provided their own horses for service instead of drawing them from the government.[191]
Although cavalry was used extensively throughout the world during the 19th century, horses became less important in warfare at the beginning of the 20th century.Light cavalry was still seen on the battlefield, but formal mounted cavalry began to be phased out for combat during and immediately afterWorld War I, although units that included horses still had military uses well intoWorld War II.[192]
World War I saw great changes in the use of cavalry. The mode of warfare changed, and the use oftrench warfare,barbed wire andmachine guns rendered traditional cavalry almost obsolete.Tanks, introduced in 1917, began to take over the role of shock combat.[193]
Early in the War, cavalry skirmishes were common, and horse-mounted troops widely used for reconnaissance.[194] On theWestern Front cavalry were an effective flanking force during the "Race to the Sea" in 1914, but were less useful oncetrench warfare was established.[195][196] There a few examples of successful shock combat, and cavalry divisions also provided important mobile firepower.[159] Cavalry played a greater role on theEastern Front, where trench warfare was less common.[196] On the Eastern Front, and also against theOttomans, the "cavalry was literally indispensable."[159]British Empire cavalry proved adaptable, since they were trained to fight both on foot and while mounted, while other European cavalry relied primarily on shock action.[159]
On both fronts, the horse was also used as apack animal. Because railway lines could not withstand artillery bombardments, horses carried ammunition and supplies between the railheads and the rear trenches, though the horses generally were not used in the actual trench zone.[197] This role of horses was critical, and thus horsefodder was the single largest commodity shipped to the front by some countries.[197] Following the war, many cavalry regiments were converted to mechanised, armoured divisions, with light tanks developed to perform many of the cavalry's original roles.[198]
Several nations used horse units duringWorld War II. ThePolish army used mounted infantry to defend against the armies ofNazi Germany during the1939 invasion.[199] Both the Germans and theSoviet Union maintained cavalry units throughout the war,[165] particularly on theEastern Front.[159] The British Army used horses early in the war, and the final British cavalry charge was on March 21, 1942, when theBurma Frontier Force encounteredJapanese infantry in centralBurma.[200] The only American cavalry unit during World War II was the26th Cavalry. They challenged the Japanese invaders ofLuzon, holding off armoured and infantry regiments during theinvasion of the Philippines, repelled a unit of tanks inBinalonan, and successfully held ground for the Allied armies' retreat toBataan.[201]
Throughout the war, horses and mules were an essential form of transport, especially by the British in the rough terrain ofSouthern Europe and theMiddle East.[202] The United States Army utilised a few cavalry and supply units during the war, but there were concerns that the Americans did not use horses often enough. In the campaigns inNorth Africa, generals such asGeorge S. Patton lamented their lack, saying, "had we possessed an American cavalry division with pack artillery in Tunisia and in Sicily, not a German would have escaped."[192]
The German and the Soviet armies used horses until the end of the war for transportation of troops and supplies. The German Army, strapped for motorised transport because its factories were needed to produce tanks and aircraft, used around 2.75 million horses – more than it had used in World War I.[197] One German infantry division in Normandy in 1944 had 5,000 horses.[165] The Soviets used 3.5 million horses.[197]
While many statues and memorials have been erected to human heroes of war, often shown with horses, a few have also been created specifically to honor horses or animals in general. One example is theHorse Memorial inPort Elizabeth in theEastern Cape province ofSouth Africa.[203] Both horses and mules are honored in theAnimals in War Memorial inLondon's Hyde Park.[204]
Horses have also at times received medals for extraordinary deeds. After theCharge of the Light Brigade during theCrimean War, a surviving horse named Drummer Boy, ridden by an officer of the8th Hussars, was given an unofficial campaign medal by his rider that was identical to those awarded to British troops who served in the Crimea, engraved with the horse's name and an inscription of his service.[205] A more formal award was thePDSADickin Medal, an animals' equivalent of theVictoria Cross, awarded by thePeople's Dispensary for Sick Animals charity in the United Kingdom to three horses that served in World War II.[204]
Today, many of the historical military uses of the horse have evolved into peacetime applications, including exhibitions,historical reenactments, work ofpeace officers, and competitive events. Formal combat units of mounted cavalry are mostly a thing of the past, with horseback units within the modern military used for reconnaissance, ceremonial, or crowd control purposes. With the rise of mechanised technology, horses in formal national militias were displaced bytanks andarmored fighting vehicles, often still referred to as "cavalry".[206]
Organised armed fighters on horseback are occasionally seen. The best-known current examples are theJanjaweed, militia groups seen in theDarfur region ofSudan, who became notorious for their attacks upon unarmed civilian populations in theDarfur conflict.[207] Many nations still maintain small numbers of mounted military units for certain types of patrol and reconnaissance duties in extremely rugged terrain, including the conflict inAfghanistan.[208] Horses and donkeys have been used by Russia's army for supply and reinforcement in theRussian invasion of Ukraine, as vehicular resupply became dangerous due to the prevalence ofattack drones.[209]
At the beginning ofOperation Enduring Freedom,Operational Detachment Alpha 595 teams were covertly inserted intoAfghanistan on October 19, 2001.[210] Horses were the only suitable method of transport in the difficult mountainous terrain ofNorthern Afghanistan.[211] They were the first U.S. soldiers to ride horses into battle since January 16, 1942, when the U.S. Army’s26th Cavalry Regiment charged an advanced guard of the 14th Japanese Army as it advanced from Manila.[212][213][214]
The only remaining operationally ready, fully horse-mounted regularregiment in the world is theIndian Army's61st Cavalry.[215]
Mounted police have been used since the 18th century, and still are used worldwide to control traffic and crowds, patrol public parks, keep order in processionals and during ceremonies and perform general street patrol duties. Today, many cities still have mounted police units. In rural areas, horses are used by law enforcement for mounted patrols over rugged terrain, crowd control at religious shrines, and border patrol.[216]
In rural areas, law enforcement that operates outside of incorporated cities may also have mounted units. These include specially deputised, paid or volunteermounted search and rescue units sent into roadless areas on horseback to locate missing people.[217] Law enforcement inprotected areas may use horses in places where mechanised transport is difficult or prohibited. Horses can be an essential part of an overall team effort as they can move faster on the ground than a human on foot, can transport heavy equipment, and provide a more rested rescue worker when a subject is found.[218]
Many countries throughout the world maintain traditionally trained and historically uniformed cavalry units for ceremonial, exhibition, or educational purposes. One example is the Horse Cavalry Detachment of the U.S. Army's1st Cavalry Division.[219] This unit of active duty soldiers approximates the weapons, tools, equipment and techniques used by the United States Cavalry in the 1880s.[39] It is seen at change of command ceremonies and other public appearances.[39] A similar detachment is theGovernor General's Horse Guards, Canada'sHousehold Cavalry regiment, the last remaining mounted cavalry unit in the Canadian Forces.[220][221]Nepal's King's Household Cavalry is a ceremonial unit with over 100 horses and is the remainder of the Nepalese cavalry that existed since the 19th century.[222] An important ceremonial use is in military funerals, which often have acaparisoned horse as part of the procession, "to symbolize that the warrior will never ride again".[223]
Horses are also used in many historical reenactments.[224] Reenactors try to recreate the conditions of the battle or tournament with equipment that is as authentic as possible.[225]
Modern-day Olympic equestrian events are rooted in cavalry skills and classical horsemanship.[226] The first equestrian events at theOlympics were introduced in 1912, and through 1948, competition was restricted to active-duty officers on military horses.[227] Only after 1952, as mechanisation of warfare reduced the number of military riders, were civilian riders allowed to compete.[228][229] Dressage traces its origins toXenophon and his works on cavalry training methods, developing further during theRenaissance in response to a need for different tactics in battles where firearms were used.[230] The three-phase competition known asEventing developed out of cavalry officers' needs for versatile, well-schooled horses.[231] Thoughshow jumping developed largely fromfox hunting, the cavalry considered jumping to be good training for their horses,[232] and leaders in the development of modern riding techniques over fences, such asFederico Caprilli, came from military ranks.[233] Beyond the Olympic disciplines are other events with military roots. Competitions with weapons, such asmounted shooting andtent pegging, test the combat skills of mounted riders.[234]
