A war elephant is an elephant trained and guided by humans for combat. Their main use was to charge the enemy, trampling them and breaking their ranks. A division of war elephants is known as elephantry.

They were probably first employed in India, the practice spreading out across south-east Asia and westwards into the Mediterranean. Their most famous use in the West was by the Greek general Pyrrhus of Epirus and in great numbers by the armies of Carthage, especially under Hannibal.

In the Mediterranean, improved tactics reduced the value of the elephant in battle, while their availability in the wild also decreased. In the east, where supplies of animals were greater and the terrain ideal, it was the advent of cannon that finally concluded the use of the combat elephant at the end of the 19th century, limiting them thereafter to engineering and labour roles.

History

Taming

The first elephant species to be tamed was the Asian Elephant, for use in agriculture. Elephant taming - not full domestication, as they were still captured in the wild, rather than being bred in captivity - may have begun in any of three different places. The oldest evidence of tamed elephants is in a Mesopotamian relief, around 4,500 years ago. Another possible candidate is the Indus Valley Civilization, from approximately the same date. Archaeological evidence for the presence of wild elephants in the Yellow River valley during the Shang Dynasty (1600-1100 BCE) has also led to China being suggested as an initial site for the taming of elephants.^[1] The wild elephant populations of Mesopotamia and China declined quickly because of deforestation and human overpopulation: by c. 850 BCE the Mesopotamian elephants were extinct, and by c. 500 BCE the Chinese elephants were seriously reduced in numbers and limited to areas well south of the Yellow River.

Capturing elephants from the wild remained a difficult task, but a necessary one given the difficulties of breeding in captivity and the long time required for an elephant to reach sufficient maturity to engage in battle. It is commonly thought that all war elephants were male because of males' greater aggression, but it is rather because the female elephant in battle, will run from a male, therefore only males could be used in war, although female elephants were more commonly used for logistics.^[2]

Antiquity: India, Persia and Alexander the Great

There is uncertainty as to when elephant warfare first began. The earliest Indian Vedic religious hymns, the Rigveda, dating from the late 2nd and early 1st millennia BCE, make reference to the use of elephants for transport - especially Indra and his divine white elephant, Airavata - but make no reference to the use of elephants in war, focusing instead of Indra's role in leading horse cavalry.^[3] The later stories of the Mahabharata, dating from around the 8th century BCE in their earliest forms, and the Ramayana, dating from around the 4th century BCE,^[4] do however mention elephant warfare, suggesting its introduction during the intervening period.^[5] The ancient Indian kings certainly valued the elephant in war, some stating that 'an army without elephants is as despicable as a forest without a lion, a kingdom without a king or as valour unaided by weapons.'^[6]

From India, military thinking on the use of war elephants spread westwards to the Persian Empire, where they were used in several campaigns and in turn came to influence the campaigns of Alexander the Great. The first confrontation between Europeans and the Persian war elephants occurred at the Alexander's Battle of Gaugamela (331 BCE), where the Persians deployed fifteen elephants.^[7] These elephants were placed at the centre of the Persian line and made such an impression on the Macedonian troops that Alexander felt the need to sacrifice to the God of Fear the night before the battle - but according to some sources the elephants ultimately failed to deploy in the final battle owing to their long march the day before.^[8] Alexander won resoundingly at Gaugamela, but was deeply impressed by the enemy elephants and took these first fifteen into his own army, adding to their number during his capture of the rest of Persia.

By the time Alexander reached the borders of India five years later, he had a substantial number of elephants under his own command. When it came to defeating Porus, who ruled in the Punjab region of modern day Pakistan, Alexander found himself facing a considerable force of between 85 and 100 war elephants^[9][10] at the Battle of the Hydaspes River. Preferring stealth and mobility to sheer force, Alexander manoeuvered and engaged with just his infantry and cavalry, ultimately defeating Porus' forces, including his elephant corps, albeit at some cost. Looking further east again, however, Alexander could see that the kings of the Nanda Empire and Gangaridai could deploy as between 3,000 and 6,000 war elephants. Such a force was many times larger than the number employed by the Persians and Greeks, which discouraged Alexander's small band of men and effectively halted their advance into India.^[11] On his return, Alexander established a force of elephants to guard his palace at Babylon, and created the post of elephantarch to lead his elephant units.^[12]

The successful military use of elephants spread further. The successors to Alexander's empire, the Diadochi, used hundreds of Indian elephants in their wars, with the Seleucid empire being particularly notable for their use of the animals, still being largely brought from India. Indeed, the campaign between the Seleucids and Chandragupta Maurya (Sandrokottos), founder of the Maurya empire in 305 BCE ended with the Seleucids ceding vast eastern territories in exchange for 500 war elephants^[13] - a small part of the Maurya forces, which included up to 9,000 elephants by some accounts.^[14] The Seleucids put their new elephants to good use at the battle of Ipsus four years later. Later in its history, the Seleucid Empire used elephants in its efforts to crush the Maccabean Revolt in Judea. The elephants were terrifying to the lighter-armed Jewish warriors, and the youngest of the Hasmonean brothers, Eleazar Maccabeus, famously defeated one of the creatures in the Battle of Beth Zechariah, sticking a spear under the belly of an elephant he mistakenly believed to be carrying Seleucid king Antiochus V, killing the elephant at the cost of Eleazar's own life.^[15]

Antiquity: the Mediterranean

The Egyptians and the Carthaginians began acquiring African elephants for the same purpose, as did the Numidians and the Kushites. The animal used was the North African forest elephant^[16] which would become extinct from over-exploitation.^[17] These animals were smaller than the Asian elephants used by the Seleucids on the east of the Mediterranean region, particularly those from Syria,^[18] which stood 2.5-3.5 meters (8-10 ft) at the shoulder. It is likely that at least some Syrian elephants were traded abroad - the favourite elephant of Hannibal was an impressive animal named Surus ("the Syrian"), for example, and may have been of Syrian stock, though the evidence remains ambiguous.^[19]

Since the late 1940s a strand of scholarship has argued that the African forest elephants used by Numidian, Ptolemaic and Punic armies did not carry howdahs or turrets in combat, perhaps owing to the physical weakness of the species.^[20] Some allusions to turrets in ancient literature are certainly anachronistic or poetic invention, but other references are less easily discounted. There is explicit contemporary testimony that the army of Juba I of Numidia included turreted elephants in 46 BCE.^[21] This is confirmed by the image of a turreted African elephant used on the coinage of Juba II.^[22]. This also appears to be the case with Ptolemaic armies: Polybius reports that at the battle of Raphia in 217 BCE the elephants of Ptolemy IV carried turrets; these beasts were significantly smaller than the Asian elephants fielded by the Seleucids and so presumably African forest elephants.^[23] There is also evidence that Carthaginian war elephants were furnished with turrets and howdahs in certain military contexts.^[24].

Farther south, tribes would have had access to the African Savanna elephant.^[25] Although much larger than either the African forest elephant or the Asian elephant, these proved difficult to tame for war purposes and were not used extensively.^[26] Some Asian elephants were traded westwards to the Mediterranean markets; Pliny the Elder stated that the Sri Lankan elephants, for example, were larger, fiercer and better for war than local elephants. This superiority, as well as the proximity of the supply to seaports, made Sri Lanka's elephants a lucrative trading commodity.^[27]

Although the use of war elephants in the Mediterranean is most famously associated with the wars between Carthage and Rome, the introduction of war elephants was primarily the result of the Greek kingdom of Epirus. King Pyrrhus of Epirus brought twenty elephants to attack the Romans at the battle of Heraclea in 280 BCE, leaving some fifty additional animals, on loan from Pharaoh Ptolemy II, on the mainland. The Romans were unprepared for fighting elephants, and the Greek forces routed the Romans. The next year, the Greeks again deployed a similar force of elephants, attacking the Romans at the battle of Asculum. This time the Romans came prepared with flammable weapons and anti-elephant devices: these were ox-led chariots, equipped with long spikes to wound the elephants, pots of fire to scare them, and accompanying screening troops who would hurl javelins at the elephants to drive them away. A final charge of Greek elephants won the day again, but this time Pyrrhus had suffered very heavy casualties - a Pyrrhic victory.

Battle of Zama by Henri-Paul Motte, 1890

Inspired by these victories, Carthage developed its own use of war elephants and deployed them extensively during the First Punic War. The results were not inspiring. At Adyss in 255 BCE, the Carthaginian elephants were ineffective due to the terrain, whilst at the battle of Panormus in 251 BCE the Romans were able to terrify the Carthaginian elephants, which fled from the field. During the Second Punic War, Hannibal famously led an army of war elephants across the Alps - although unfortunately most of them perished in the harsh conditions. The Romans had developed effective anti-elephant tactics, leading to Hannibal's defeat at his final battle of Zama in 202 BCE; his elephant charge was ineffective because the disciplined Roman maniples simply made way for them to pass.

Rome brought back many elephants at the end of the Punic Wars, and used them in its campaigns for many years afterwards. The conquest of Greece saw many battles in which the Romans deployed war elephants, including the invasion of Macedonia in 199 BCE, the battle of Cynoscelphalae 197 BCE,^[28] the battle of Thermopylae,^[29] and the battle of Magnesia in 190 BCE, during which Antiochus III's fifty-four elephants took on the Roman force of sixteen. In later years the Romans deployed twenty-two elephants at Pydna in 168 BCE.^[30] They also featured throughout the Roman campaign against the Celtiberians in Hispania and against the Gauls. Famously, the Romans used a war elephant in the invasion of Britain, one ancient writer recording that 'Caesar had one large elephant, which was equipped with armor and carried archers and slingers in its tower. When this unknown creature entered the river, the Britons and their horses fled and the Roman army crossed over',^[31] - although he may have confused this incident with the use of a similar war elephant in Claudius' final conquest of Britain. At least one elephant skeleton with flint weapons that has been found in England was initially misidentified as these elephants, but later dating proved it to be a mammoth skeleton from the stone age.^[32]

By the time of Claudius, however, such animals were being used by the Romans in single numbers only - the last significant use of war elephants in the Mediterranean was against the Romans at the battle of Thapsus, 46 BCE, where Julius Caesar armed his fifth legion (Alaudae) with axes and commanded his legionaries to strike at the elephant's legs. The legion withstood the charge, and the elephant became its symbol. Thapsus was the last significant use of elephants in the West.^[33]

The Parthian dynasty of Persia occasionally used war elephants in their battles against the Roman Empire but elephants were of substantial importance in the army of the subsequent Sassanid dynasty.^[34] The Sassanids employed the animals in many of their campaigns against their western enemies. One of the most memorable engagements was the Battle of Vartanantz in 451 AD, at which the Sassanid elephants terrified the Armenians. Another example is the Battle of al-Qādisiyyah of 636 AD, in which a unit of thirty-three elephants were used, albeit less successfully, against the invading Arab forces. The Sassanid elephant corps held primacy amongst the Sassanid's cavalry forces and was recruited from India. The elephant corps was under a special chief, known as the Zend−hapet, or "Commander of the Indians," either because the animals came from that country, or because they were managed by natives of Hindustan.^[35] The Sassanid elephant corps was never on the same scale as other further east, however, and after the fall of the Sassanid empire the use of war elephants died out in the region.

Antiquity: The Far East

In China, the use of war elephants was relatively rare compared to other locations.^[36][37] Their earliest recorded use took place as late as 554 AD when the Western Wei deployed two armored war elephants from Lingnan in battle, guided by Malay slaves, and equipped with wooden towers, and swords fastened onto their trunks.^[36] The elephants were turned away by archers' arrows.^[36] The Song Dynasty also defeated an elephant corps of the Southern Han with massed crossbow fire.

The Han Dynasty of the 2nd century BCE fought against Yue kingdoms of South East Asia that did employ war elephants. Common tactics used to repel these elephants included massed crossbow or artillery fire, and digging pits or trenches filled with spikes.

By comparison, neighbouring states significantly embraced the use of war elephants. Sri Lankan history records indicate elephants were used as mounts for kings leading their men in the battle field,^[38] with individual mounts being recorded in history. The elephant Kandula was King Dutugamunu's mount and Maha Pambata, 'Big Rock', the mount of King Elara during their historic encounter on the battlefield in 200 BCE, for example.^[39] In Southeast Asia, along the borders of in modern day Vietnam, the Champan army employed up to 602 war elephant against the Sui Chinese.^[40] The Sui troops led the elephants into a trap of falling into deep pits dug by them, also making extensive use of crossbows.^[40]

Middle Ages

In the Middle Ages, elephants were seldom used in Europe. Charlemagne took his elephant, Abul-Abbas, when he went to fight the Danes in 804,^[41] and the Crusades gave Holy Roman Emperor Frederick II the opportunity to capture an elephant in the Holy Land, the same animal later being used in the capture of Cremona in 1214, but the use of these individual animals was more symbolic than practical.

The Khmer army waged war with elephants against the Cham in the 12th century.

Farther east, elephants continued to be used in warfare. The Mongols faced war-elephants in Khorazm, Burma, Vietnam and India throughout the 1200s.^[42] Despite their unsuccessful campaigns in Vietnam and India, the Mongols defeated the war elephants outside Samarkand by using catapults and mangonels, and in Burma by showering arrows from their famous composite bow.^[43] Genghis and Kublai both retained captured elephants as part of their entourage.^[44] Another central Asian invader, Timur faced similar challenges a century later. In 1398 Timur's army faced more than one hundred Indian elephants in battle and almost lost because of the fear they caused amongst his troops. Historical accounts say that the Timurids ultimately won by employing an ingenious strategy: Timur tied flaming straw to the back of his camels before the charge. The smoke made the camels run forward, scaring the elephants, who crushed their own troops in their efforts to retreat. Another account of the campaign reports that Timur used oversized caltrops to halt the elephants' charge.^[45] Later, the Timurid leader used the captured animals against the Ottoman Empire.

It is recorded that King Rajasinghe I, when he laid siege to the Portuguese fort at Colombo, Sri Lanka in 1558, had an army of 2200 elephants. ^[46] The Sri Lankans had continued their proud traditions in capturing and training elephants from ancient times. The officer in charge of the royal stables, including the capture of elephants, was called the Gajanayake Nilame,^[47] whilst the post of Kuruve Lekham controlled the Kuruwe or elephant men^[48] - the training of war elephants was the duty of the Kuruwe clan who came under their own Muhandiram, a Sri Lankan administrative post.

In the Southeast Asia, the powerful Khmer Empire had come to regional dominance by the 9th century AD, drawing heavily on the use of war elephants. Uniquely, the Khmer military deployed double cross-bows on the top of their elephants. With the collapse of Khmer power in the 15th century, the successor region powers of Burma (now Myanmar) and Siam (now Thailand) also adopted the widespread use of war elephants. In many battles of the period it was the practice for leaders to fight each other personally on elephants. One famous battle occurred when the Burmese army attacked Siam's Kingdom of Ayutthaya. The war was concluded when the Burmese crown prince Minchit Sra was killed by Siamese King Naresuan in personal combat on elephant in 1593.^[49]

Farther north, the Chinese continued to reject the use of war elephants throughout the period, with the notable exception of the Southern Han during the 10th century AD - the "only nation on Chinese soil ever to maintain a line of elephants as a regular part of its army".^[36] This anomaly in Chinese warfare is explained by the geographical proximity and close cultural links of the southern Han to Southeast Asia.^[36] The military officer who commanded these elephants was given the title "Legate Digitant and Agitant of the Gigantic Elephants."^[50] Each elephant supported a wooden tower that could allegedly hold ten or more men.^[51] For a brief time, war elephants played a vital role in Southern Han victories such as the invasion of Chu in 948 AD,^[51] but the Southern Han elephant corps were ultimately soundly defeated at Shao in 971 AD, decimated by crossbow fire from troops of the Song Dynasty.^[51] As one academic has put it, "thereafter this exotic introduction into Chinese culture passed out of history, and the tactical habits of the North prevailed."^[51]

Modern era

With the advent of gunpowder warfare in the late 15th century, the balance of advantage for war elephants on the battlefield began to change. Whilst muskets had limited impact on elephants, which could withstand numerous volleys,^[52] cannon fire was a different matter entirely - an animal could easily be knocked down by a single shot. With elephants still being used to carry commanders on the battlefield, they became even more tempting targets for enemy artillery.

Nonetheless, in south-east Asia the use of elephants on the battlefield continued up until the end of the 19th century. One of the major difficulties in the region was terrain, and elephants could cross difficult terrain in many cases more easily than horse cavalry. The Siamese Army was utilising war elephants armed with jingals up until the Franco-Siamese War of 1893, whilst the Vietnamese used them in battle as late as 1885, during the Sino-French War.

During World War I, elephants pulled heavy equipment. This one worked in a munitions yard in Sheffield.

Into the 20th century, non-battle-trained elephants were used for other military purposes as late as World War II,^[53] particularly because the animals could perform tasks in regions that were problematic for modern vehicles.

Elephants are now more valuable to many armies in failing states for their ivory than as transport, and many thousands of elephants have died during civil conflicts due to poaching. They are classed as a pack animal in a U.S. Special Forces field manual issued as recently as 2004, but their use by US personnel is discouraged because elephants are an endangered species.^[54] The last recorded use of elephants in war occurred in 1987 when Iraq was alleged to have used them to transport heavy weaponry for use in Kirkuk.

Tactical use

There were many military purposes for which elephants could be used. In battle, war elephants were usually deployed in the centre of the line, where they could be useful to prevent a charge or to conduct one of their own. Their sheer size and their terrifying appearance made them valued heavy cavalry.^[55] Off the battlefield, they could carry heavy materiel and provided a useful means of transport before mechanized vehicles rendered them mostly obsolete.

An elephant charge could reach about 30 km/h (20 mph), and unlike horse cavalry, could not be easily stopped by an infantry line setting spears. Such a charge was based on pure force: elephants crashing into an enemy line, trampling and swinging their tusks. Those men who were not crushed were at least knocked aside or forced back. Moreover, elephants could inspire terror in an enemy unused to fighting them - even the very disciplined Romans - and could cause the enemy to break and flee. Horses unaccustomed to the smell of elephants also panicked easily. The elephants' thick hide gave them considerable protection, whilst their height and mass offered considerable protection for their riders. Many generals preferred to base themselves from elephants so as to get a better view of the battlefield.

In addition to charging, the elephants could provide a safe and stable platform for archers to fire arrows in the middle of the battlefield, from which more targets could be seen and engaged. The archery evolved into more advanced weapons, and several Khmer and Indian kings used giant crossbow platforms (similar to the ballista) to fire long armor-piercing shafts to kill other enemy war elephants and cavalry. The late 1500s AD also saw the use of culverin and jingals on elephants, an adaptation to the gunpowder age that would ultimately drive elephants from on the battlefield.

Elephants were further enhanced with their own weaponry and armour. In Sri Lanka, heavy iron chains with steel balls at the end were tied to the trunks of war elephants, which the animals were trained to swirl menacingly and with great skill. Numerous cultures designed elephant Armour, aiming to protect the body and legs of the animal whilst leaving his trunk free to attack the enemy. Larger animals could also carry a protective tower on their backs, called a howdah.

In the Punic wars a crew of three men were used in battle: archers and potentially men armed with sarissas (six metre long pikes). Further east, large numbers of men were carried, with the senior commander either utilising the howdah or leading from his seat on the elephant's neck. The driver, called a mahout, was responsible for controlling the animal. In many armies, the mahout also carried a chisel-blade and a hammer to cut through the spinal cord and kill the animal if the elephant went berserk.

War elephants had tactical weaknesses, however, that enemy forces often learnt to exploit. Elephants had a tendency to panic themselves: after sustaining painful wounds or when their driver was killed they would run amok,^[55] indiscriminately causing casualties as they sought escape. Their panicked retreat could inflict heavy losses on either side. Experienced Roman infantry often tried to sever their trunks, causing an instant panic, and hopefully causing the elephant to flee back into its own lines. Fast skirmishers armed with javelins were also used to drive them away, as javelins and similar weapons could madden an elephant. The cavalry sport of tent pegging grew out of training regimes for horsemen to incapacitate or turn back war elephants.^[56] One famous historical method for disrupting elephant units was the war pig. Ancient writers believed that "elephants are scared by the smallest squeal of a pig",^[57] and the vulnerability was exploited. At the Megara during the Diachoi wars, for example, the Megarians reportedly poured oil on a herd of pigs, set them alight, and drove them towards the enemy's massed war elephants. The elephants bolted in terror from the flaming squealing pigs.^[58]

The value of war elephants in battle remains a contested issue. In the 19th century, it was fashionable to contrast the western, Roman focus on infantry and discipline with the eastern, exotic use of war elephants that relied merely on fear to defeat their enemy.^[59] One writer commented that war elephants "have been found to be skittish and easily alarmed by unfamiliar sounds and for this reason they were found prone to break ranks and flee."^[60] Nonetheless, the continued use of war elephants for several thousand years speaks to their enduring value to the historical battlefield commander.

Cultural legacy

The use of war elephants over the centuries has left a deep cultural legacy in many countries. Many traditional war games incorporate war elephants. Shatranj (Persian chess) — from which Modern chess has gradually developed - calls its bishop fil, meaning elephant in Persian. In Spanish and Arabic the bishop piece is called al-fil, and in Russian the bishop is also an elephant (Слон). Similarly in Indian Chaturanga the bishop piece was originally a war elephant (Gaja), which is still the case in Chinese Chess. In the Japanese Shogi game, there used to be a piece known as the "Drunken Elephant"; it was, however, dropped by order of the Emperor Go-Nara and no longer appears in the version played in contemporary Japan.

Elephant armour, originally designed for use in war, is today usually only seen in museums. One particularly fine set of Indian elephant armour is preserved at the Leeds Royal Armouries Museum, whilst Indian museums across the sub-continent display other fine pieces. The architecture of India also shows the deep impact of elephant warfare over the years. War elephant adorn many military gateways, such as those at Lohagarh Fort for example, whilst some spiked, anti-elephant gates still remain, for example at Kumbhalgarh fort. Across India, older gateways are invariably much higher than their European equivalents, in order to allow elephants with howdahs to pass through underneath.

War elephants also remain a popular artistic trope, either in the Orientalist painting tradition of the 19th century, or in literature following Tolkien, who popularised a fantastic rendition of war elephants in the form of oliphaunts.
