War elephant
A war elephant is an elephant that is trained and guided by humans for combat purposes. Historically, the war elephant's main use was to charge the enemy, break their ranks, and instill terror and fear. Elephantry is a term for specific military units using elephant-mounted troops.
War elephants played a critical role in several key battles in antiquity, especially in ancient India. While seeing limited and periodic use in Ancient China, they became a permanent fixture in armies of historical kingdoms in Southeast Asia. They were also used in ancient Persia and in the Mediterranean world within armies of Macedon, Hellenistic Greek states, the Roman Republic and later Empire, and Ancient Carthage in North Africa. In some regions they maintained a firm presence on the battlefield throughout the Medieval era. However, their use declined with the spread of firearms and other gunpowder weaponry in early modern warfare. After this, war elephants became restricted to non-combat engineering and labour roles, as well as minor ceremonial uses.
Antiquity
Indian subcontinent
There is uncertainty as to when elephant warfare first started, but it is widely accepted that it began in ancient India. The early Vedic period did not extensively specify the use of elephants in war. However, in the Ramayana, Indra is depicted as riding either Airavata, a mythological elephant, or on the Uchchaihshravas, as his mounts. Elephants were widely utilized in warfare by the later Vedic period by the 6th century BC. The increased conscription of elephants in the military history of India coincides with the expansion of the Vedic Kingdoms into the Indo-Gangetic Plain suggesting its introduction during the intervening period. The practice of riding on elephants in peace and war, royalty or commoner, was first recorded in the 6th or 5th century BC. This practice is believed to be much older than proper recorded history. Elephants were also used against Alexander the Great's army in India.The ancient Indian epics Ramayana and Mahābhārata, dating from 5th–4th century BC, elaborately depict elephant warfare. They are recognized as an essential component of royal and military processions. In ancient India, initially, the army was fourfold, consisting of infantry, cavalry, elephants and chariots. Kings and princes principally rode on chariots, which were considered the most royal, while seldom riding on the backs of elephants. Although viewed as secondary to chariots by royalty, elephants were the preferred vehicle of warriors, especially the elite ones. While the chariots eventually fell into disuse, the other three arms continued to be valued. Many characters in the epic Mahābhārata were trained in the art. According to the rules of engagement set for the Kurukshetra War, two men were to duel utilizing the same weapon and mount, including elephants. In the Mahābhārata the akshauhini battle formation consists of a ratio of 1 chariot : 1 elephant : 3 cavalry : 5 infantry soldiers. Many characters in the Mahābhārata were described as skilled in the art of elephant warfare e.g. Duryodhana rides an elephant into battle to bolster the demoralized Kaurava army. Scriptures like the Nikāya and Vinaya Pitaka assign elephants in their proper place in the organization of an army. The Samyutta Nikaya additionally mentions the Gautama Buddha being visited by a 'hatthāroho gāmaṇi'. He is the head of a village community bound together by their profession as mercenary soldiers forming an elephant corp.
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 valor unaided by weapons. The use of elephants further increased with the rise of the Mahajanapadas. King Bimbisara, who began the expansion of the Magadha kingdom, relied heavily on his war elephants. The Mahajanapadas would be conquered by the Nanda Empire under the reign of Mahapadma Nanda. According to Curtius, Alexander learned that the Nanda had 200,000 infantry; 20,000 cavalry; 3,000 elephants; and 2,000 four-horse chariots. Diodorus gives the number of elephants as 4,000. Plutarch inflates these numbers significantly, except the infantry: according to him, the Nanda force included 200,000 infantry; 80,000 cavalry; 6,000 elephants; and 8,000 chariots. It is possible that the numbers reported to Alexander had been exaggerated by the local Indian population, who had the incentive to mislead the invaders. Alexander the Great would come in contact with the Nanda Empire on the banks of the Beas River and was forced to return due to his army's unwillingness to advance. Even if historic accounts exaggerated the numbers and prowess of these elephants, elephants were firmly established as war machines in this period.
At the height of his power, Chandragupta Maurya of the Maurya Empire is said to have wielded a military of 600,000 infantry, 30,000 cavalry, 8,000 chariots and 9,000 war elephants besides followers and attendants. In the Mauryan Empire, the 30-member war office was made up of six boards. The sixth board looked after the elephants, and was headed by a Gajadhyaksha, or superintendent of elephants, who was tasked with their training. The use of elephants in the Maurya Empire is recorded by Chanakya in the Arthashastra. According to Chanakya, catching, training, and controlling war elephants were among the most important skills taught by military academies. He advised Chandragupta to set up forested sanctuaries for the wellness of the elephants. Chanakya explicitly conveyed the importance of these sanctuaries. The Maurya Empire would reach its zenith under the reign of Ashoka, who used elephants extensively during his conquest. During the Kalinga War, Kalinga had a standing army of 60,000 infantry, 1000 cavalry and 700 war elephants. Kalinga was notable for the quality of its war elephants, which its neighbors prized for their strength. Later the King Kharavela was to restore an independent Kalinga into a powerful kingdom using war elephants as stated in the Hathigumpha inscription or "Elephant Cave" Inscriptions. Following Indian accounts, foreign rulers would also adopt the use of elephants.

The Chola Empire of Tamil Nadu also had a very strong elephant force. The Chola emperor Rajendra Chola had an armored elephant force, which played a major role in his campaigns.
Sri Lanka made extensive use of elephants and also exported elephants with Pliny the Elder stating 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. Sri Lankan history records indicate elephants were used as mounts for kings leading their men in the battlefield, with individual mounts being recorded in history. The elephant Kandula was King Dutugamunu's mount and Maha Pambata, 'Big Rock', the mount of King Ellalan during their historic encounter on the battlefield in 200 BC, for example.
Eastern Asia
Elephants were used for warfare in China by a small handful of southern dynasties. The state of Chu used elephants in 506 BC against Wu by tying torches to their tails and sending them into the ranks of the enemy soldiers, but the attempt failed. In December 554 AD, the Liang dynasty used armoured war elephants, carrying towers, against Western Wei. They were defeated by a volley of arrows. The Southern Han dynasty is the only state in Chinese history to have kept a permanent corps of war elephants. These elephants were able to carry a tower with some ten people on their backs. They were used successfully during the Han invasion of Ma Chu in 948. In 970, the Song dynasty invaded Southern Han and their crossbowmen readily routed the Han elephants on 23 January 971, during the taking of Shao. That was the last time elephants were used in Chinese warfare, although the Wanli Emperor did keep a herd of elephants capable of carrying a tower and eight men. These elephants were probably not native to China and were delivered to the Ming dynasty by Southeast Asian countries such as Siam. During the Revolt of the Three Feudatories, the rebels used elephants against the Qing dynasty, but the Qing Bannermen shot them with so many arrows that they "resembled porcupines" and repelled the elephant charge.Chinese armies faced off against war elephants in Southeast Asia, such as during the Sui–Lâm Ấp war, Lý–Song War, Ming–Mong Mao War, and Ming–Hồ War. In 605, the Champa kingdom of Lâm Ấp in what is now southern Vietnam used elephants against the invading army of China's Sui dynasty. The Sui army dug pits and lured the elephants into them and shot them with crossbows, causing the elephants to turn back and trample their own army. In 1075, the Song defeated elephants deployed on the borderlands of Đại Việt during the Lý–Song War. The Song forces used scythed polearms to cut the elephants' trunks, causing them to trample their own troops. During the Mong Mao campaign, the elephants were routed by an assortment of gunpowder projectiles. In the war against the Hồ dynasty, Ming troops covered their horses with lion masks to scare the elephants and shot them with firearms. The elephants all trembled with fear and were wounded by the guns and arrows, causing the Viet army to panic.
Achaemenid Persia, Macedonia and Hellenistic Greek states
From India, military thinking on the use of war elephants spread westwards to the Achaemenid Empire, where they were used in several campaigns. They in turn came to influence the campaigns of Alexander the Great, king of Macedonia in Hellenistic Greece. The first confrontation between Europeans and the Persian war elephants occurred at Alexander's Battle of Gaugamela, where the Persians deployed fifteen elephants. These elephants were placed at the centre of the Persian line and made such an impression on Alexander's army that he felt the need to sacrifice to Phobos, 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. Alexander 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 what is now Punjab region, Alexander found himself facing a force of between 85 and 100 war elephants at the Battle of the Hydaspes. 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. Porus for his part placed his elephants individually, at long intervals from each other, a short distance in front of his main infantry line, in order to scare off Macedonian cavalry attacks and aid his own infantry in their struggle against the phalanx. The elephants caused many losses with their tusks fitted with iron spikes or by lifting the enemies with their trunks and trampling them. Arrian described the subsequent fight: "herever the beasts could wheel around, they rushed forth against the ranks of infantry and demolished the phalanx of the Macedonians, dense as it was."
The Macedonians adopted the standard ancient tactic for fighting elephants, loosening their ranks to allow the elephants to pass through and assailing them with javelins as they tried to wheel around; they managed to pierce the unarmoured elephants' legs. The panicked and wounded elephants turned on the Indians themselves; the mahouts were armed with poisoned rods to kill the beasts but were slain by javelins and archers.
Looking further east again, Alexander could see that the emperors and kings of the Nanda Empire and Gangaridai could deploy between 3,000 and 6,000 war elephants. Such a force was many times larger than the number of elephants employed by the Persians and Greeks, which probably discouraged Alexander's army and effectively halted their advance into India. 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.
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 Seleucid–Mauryan war of 305–303 BC ended with the Seleucids ceding vast eastern territories in exchange for 500 war elephants – a small part of the Mauryan forces, which included up to 9000 elephants by some accounts. The Seleucids put their new elephants to good use at the Battle of Ipsus four years later, where they blocked the return of the victorious Antigonid cavalry, allowing the latter's phalanx to be isolated and defeated.
The first use of war elephants in Europe was made in 318 BC by Polyperchon, one of Alexander's generals, when he besieged Megalopolis in the Peloponnesus during the wars of the Diadochi. He used 60 elephants brought from Asia with their mahouts. A veteran of Alexander's army, named Damis, helped the besieged Megalopolitians to defend themselves against the elephants and eventually Polyperchon was defeated. Those elephants were subsequently taken by Cassander and transported, partly by sea, to other battlefields in Greece. It is assumed that Cassander constructed the first elephant transport sea vessels. Some of the elephants died of starvation in 316 BC in the besieged city of Pydna in Macedonia. Others of Polyperchon's elephants were used in various parts of Greece by Cassander.
Although the use of war elephants in the western Mediterranean is most famously associated with the wars between Carthage and Roman Republic, the introduction of war elephants was primarily the result of an invasion by Hellenistic era Epirus across the Adriatic Sea. King Pyrrhus of Epirus brought twenty elephants to attack Roman Italy at the battle of Heraclea in 280 BC, leaving fifty additional animals, on loan from Ptolemaic Pharaoh Ptolemy II, on the mainland. The Romans were unprepared for fighting elephants, and the Epirot forces routed the Romans. The next year, the Epirots 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: ox-drawn wagons, 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 Epirot elephants won the day, but this time Pyrrhus had suffered very heavy casualties.

The Seleucid king Antiochus V Eupator, whose father and he contended with Ptolemaic Egypt's ruler Ptolemy VI for control of Syria, invaded Judea in 161 BCE with eighty elephants, some of which were clad in armoured breastplates, in an attempt to subdue the Jews who had revolted during the Maccabean Revolt.
