Background

In November 333 BC, King Darius III had lost the Battle of Issus to Alexander the Great, which resulted in the subsequent capture of his wife,

and his two daughters, Stateira II and Drypetis. Alexander's victory at Issus had also given him complete control of southern Asia Minor (modern-day Turkey). After the battle, King Darius retreated to

where he regrouped with his remaining army that was there, on-site from a previous battle. Alexander fought at the Siege of Tyre (332 BC), which lasted from January to July, and the victory resulted in his control of the Levant. Alexander then again fought at the Siege of Gaza. Persian troop counts in Egypt were diminished due to many soldiers being removed to support the Battle of Issus and dying there. As a result, the Persian satrap of Egypt,

Negotiations between Darius and Alexander

Darius tried to dissuade Alexander from further attacks on his empire by diplomacy. Nawotka writes that " nflicting reports of ancient authors make the reconstruction of peace negotiations hypothetical." Ancient historians provide different accounts of his negotiations with Alexander, which can be separated into three negotiation attempts. Darius reportedly initially requested peace and the safe return of his family, beginning with an offer to pay 10,000 talents as ransom, then offering to cede land in Asia Minor west of the Halys river, and eventually offering to recognize Alexander as a co-equal status as monarch. Alexander rejected all of these offers. Historians Justin,

, writing in the 1st and 2nd centuries, say that Darius had sent a letter to Alexander after the Battle of Issus. The letter demanded that Alexander withdraw from Asia as well as release all of his prisoners. According to Curtius and Justin, Darius offered a ransom for his prisoners, although Arrian does not mention a ransom. Curtius describes the tone of the letter as offensive, and Alexander refused his demands. A second negotiation attempt took place after the capture of Tyre. Darius offered Alexander marriage with his daughter Stateira II, as well as all the territory west of the Halys river. Justin is less specific, and does not mention a specific daughter, and only speaks of a portion of Darius' kingdom.

Diodorus is the only ancient historian who mentions the fact that Alexander concealed this letter and presented his friends with a forged one that was favorable to his own interests. Again, Alexander refused Darius' offers. King Darius started to prepare for another battle with Alexander after the failure of the second negotiation attempt. Nevertheless, Darius made a third and final effort to negotiate with Alexander the Great after Alexander had departed from Egypt. Darius' third offer was much more generous.

, co-rulership of the Achaemenid Empire, the hand of one of his daughters and 30,000 talents of silver. In the account of Diodorus, Alexander explicitly deliberated this offer with his friends. Parmenion was the only one who spoke up, saying, "If I were Alexander, I should accept what was offered and make a treaty." Alexander reportedly replied, "So should I, if I were Parmenion." Alexander, in the end, refused the offer of Darius, and insisted that there could be only one king of Asia. He called on Darius to surrender to him or to meet him in battle in order to decide who would be the sole king of Asia. The descriptions given by other historians of the third negotiation attempt are similar to the account of Diodorus, but differ in details. Diodorus, Curtius and Arrian write that an embassy was sent instead of a letter, which is also claimed by Justin and Plutarch (1st century). Plutarch and Arrian mention the ransom offered for the prisoners was 10,000 talents, but Diodorus, Curtius and Justin had given the figure of 30,000. Arrian writes that Darius' third attempt took place during the Siege of Tyre, but the other historians place the second negotiation attempt at that time. In spite of everything, with the failure of his negotiation attempts, Darius had now decided to prepare for another battle with Alexander.


Prelude

In the late spring or early summer of 331 BC, Alexander headed from Egypt, northeast through Syria, toward the Tigris river. In July or August, Alexander reached
Thapsacus Thapsacus ( grc, Θάψακος, Thapsakos; he, תִּפְסַח ''Tipsah'') was an ancient town along the western bank of the Euphrates river that would now lie in modern Syria. Thapsacus was the Greek and Roman name for the town. The town was imp ...

river. Arrian relates that Darius had ordered Mazaeus to guard the crossing of the Euphrates near Thapsacus with a force of 3,000 cavalry, and that he fled when Alexander's army approached to cross the river. Alexander arrived at the Tigris in late September.


Alexander's march through Mesopotamia

Alexander crossed the Euphrates in the summer of 331 BC. From there, Alexander followed a northern route instead of a direct southeastern route to Babylon. While doing so he had the Euphrates and the mountains of Armenia on his left. The northern route made it easier to forage for supplies and his troops would not suffer the extreme heat of the direct route. Captured Persian scouts reported to the Macedonians that Darius had encamped past the Tigris river. Alexander found the Tigris undefended and succeeded in crossing it with great difficulty. By contrast, Diodorus mentions that Mazaeus was only supposed to prevent Alexander from crossing the Tigris. He would not have bothered to defend it because he considered it impassable due to the strong current and depth of the river. Furthermore, Diodorus and Curtius Rufus mention that Mazaeus employed scorched-earth tactics in the countryside through which Alexander's army had to pass. After the Macedonian army had crossed the Tigris, a near-total

occurred on 20–21 September 331 BC. Four days later, Alexander's army spotted members of Mazaeus' cavalry and captured one or two, who gave information about the location of Darius' army at Gaugamela, some eight miles away. In light of the ground-flattening efforts taking place at Gaugamela, Alexander determined that Darius did not intend to change locations, and allowed his troops four days to rest before engaging Darius' army in battle. Following the calculations, the date of the Battle of Gaugamela must have been 1 October in 331 BC.


Strategic analysis

Several researchers have criticized the Persians for their failure to harass Alexander's army and disrupt its long supply lines when it advanced through Mesopotamia. Classical scholar Peter Green thinks that Alexander's choice for the northern route caught the Persians off guard. Darius would have expected him to take the faster southern route directly to
Babylon ''Bābili(m)'' * sux, 𒆍𒀭𒊏𒆠 * arc, 𐡁𐡁𐡋 ''Bāḇel'' * syc, ܒܒܠ ''Bāḇel'' * grc-gre, Βαβυλών ''Babylṓn'' * he, בָּבֶל ''Bāvel'' * peo, 𐎲𐎠𐎲𐎡𐎽𐎢 ''Bābiru'' * elx, 𒀸𒁀𒉿𒇷 ''Babi ...

had done in 401 BC before his defeat in the Battle of Cunaxa. The use of the scorched-earth tactic and scythed chariots by Darius suggests that he wanted to repeat that battle. Alexander would have been unable to adequately supply his army if he had taken the southern route, even if the scorched-earth tactic had failed. The Macedonian army, underfed and exhausted from the heat, would then be defeated at the plain of Cunaxa by Darius. When Alexander took the northern route, Mazaeus must have returned to Babylon to bring the news. Darius most likely decided to prevent Alexander from crossing the Tigris. This plan failed because Alexander probably took a river crossing that was closer to Thapsacus than Babylon. He would have improvised and chosen Gaugamela as his most favourable site for a battle. Historian Jona Lendering, by contrast, argues that Darius intentionally led the Macedonians to Gaugamela, the Persians' preferred battlefield.

Size of Persian army


Modern estimates

Although there is general acceptance among modern scholars of Arrian's numbers for Alexander's forces, the opposite is true with respect to the ancient sources' reports on Darius's troop size. According to Bichler, among modern authors, " eir common ground is only that the excessively high numbers given in the ancient sources are of no use." Similarly, Worthington writes that the figures given by Diodorus, Plutarch, and Curtius "are absurdly high numbers to show how hopelessly outnumbered Alexander's army was Reinhold Bichler's case study surveyed 20 different sources published between 1920 and 2014, showing that various authors have given widely divergent estimates of Darius's forces, with others remarking that it is not possible to reach any conclusion other than that Alexander's army was outnumbered by the Persians. Hans Delbrück estimates Persian cavalry at 12,000 because of management issues, Persian infantry less than that of the Greek heavy infantry, and Greek mercenaries at 8,000. estimates a total size of 91,000; 120,000; and no larger than 100,000.

s or the Hindush. While Darius had a significant advantage in numbers, most of his troops were of a lower quality than Alexander's. Alexander's pezhetairoi were armed with a six-metre pike, the sarissa. The main Persian infantry was poorly trained and equipped in comparison to Alexander's pezhetairoi and hoplites. The only respectable infantry Darius had were his 2,000 Greek hoplites and his personal bodyguard, the 10,000 Immortals. The Greek mercenaries fought in a phalanx, armed not with a heavy shield but with spears no longer than three metres, while the spears of the Immortals were two metres long. Among the other Persian troops, the most heavily armed were the Armenians, who were armed the Greek way and probably fought as a phalanx.

Alexander commanded Greek forces from his kingdom of Macedon and the Hellenic League, along with Greek mercenaries and levies from the Paeonian and Thracian tributary peoples. According to

Darius placed himself in the center with his best infantry, as was the tradition among Persian kings.

In the right-center, he placed Persian foot guards (Apple Bearers/Immortals to the Greeks), the Indian cavalry and his Mardian archers. On both flanks were the cavalry.

n and Greek light cavalry. The mercenary cavalry was divided into two groups, veterans on the flank of the right and the rest in front of the Agrianes and Greek archers, who were stationed next to the phalanx. Parmenion was stationed on the left with the Thessalians, Greek mercenaries and Thracian cavalry. There they were to conduct a holding action while Alexander launched the decisive blow from the right. On the right-center were Cretan mercenaries. Behind them were Thessalian cavalry under Phillip, and Achaean mercenaries. To their right was another part of the allied Greek cavalry. From there came the phalanx, in a double line. Outnumbered over 5:1 in the cavalry, with their line surpassed by over a mile, it seemed inevitable that the Greeks would be flanked by the Persians. The second line was given orders to deal with any flanking units should the situation arise. This second line consisted mostly of mercenaries.


Beginning of the battle

Alexander began by ordering his infantry to march in phalanx formation towards the center of the enemy line. The Macedonians advanced with the wings echeloned back at 45 degrees to lure the Persian cavalry to attack. While the phalanxes battled the Persian infantry, Darius sent a large part of his cavalry and some of his regular infantry to attack Parmenion's forces on the left. During the battle, Alexander employed an unusual strategy which has been duplicated only a few times. While the infantry battled the Persian troops in the centre, Alexander began to ride all the way to the edge of the right flank, accompanied by his Companion Cavalry. His plan was to draw as much of the Persian cavalry as possible to the flanks, to create a gap within the enemy line where a decisive blow could then be struck at Darius in the centre. This required almost perfect timing and maneuvering and Alexander himself to act first. He would force Darius to attack (as they would soon move off the prepared ground), though Darius did not want to be the first to attack after seeing what happened at Issus against a similar formation. In the end, Darius' hand was forced, and he attacked.


Cavalry battle in the Hellenic right wing

The Scythian cavalry from the Persian left wing opened the battle by attempting to flank Alexander's extreme right. What followed was a long and fierce cavalry battle between the Persian left and the Macedonian right, in which the latter, being greatly outnumbered, was often hard-pressed. However, by careful use of reserves and disciplined charges, the Greek troops were able to contain their Persian counterparts, which would be vital for the success of Alexander's decisive attack. As told by Arrian:
Then the Scythian cavalry rode along the line and came into conflict with the front men of Alexander's array, but he nevertheless still continued to march towards the right, and almost entirely got beyond the ground which had been cleared and levelled by the Persians. Then Darius, fearing that his chariots would become useless, if the Macedonians advanced into the uneven ground, ordered the front ranks of his left wing to ride round the right wing of the Macedonians, where Alexander was commanding, to prevent him from marching his wing any further. This being done, Alexander ordered the cavalry of the Grecian mercenaries under the command of Menidas to attack them. But the Scythian cavalry and the Bactrians, who had been drawn up with them, sallied forth against them and being much more numerous they put the small body of Greeks to rout. Alexander then ordered Aristo at the head of the Paeonians and Grecian auxiliaries to attack the Scythians, and the barbarians gave way. But the rest of the Bactrians, drawing near to the Paeonians and Grecian auxiliaries, caused their own comrades who were already in flight to turn and renew the battle; and thus they brought about a general cavalry engagement, in which more of Alexander's men fell, not only being overwhelmed by the multitude of the barbarians, but also because the Scythians themselves and their horses were much more completely protected with armour for guarding their bodies. Notwithstanding this, the Macedonians sustained their assaults, and assailing them violently squadron by squadron, they succeeded in pushing them out of rank.
The tide finally turned in the Greek favor after the attack of
Aretes Aretes ( el, Ἀρέτης) or Aretas ( el, Ἀρέτας) was a Macedonian general. At the Battle of Gaugamela, he commanded the sarissophoroi (also known as ''prodromoi''), a unit of versatile cavalry, adept at scouting, but with an ability for c ...

, likely their last reserve in this sector of the battlefield. By then, however, the battle had been decided in the center by Alexander himself.
The Persians also who were riding round the wing were seized with alarm when Aretes made a vigorous attack upon them. In this quarter indeed the Persians took to speedy flight; and the Macedonians followed up the fugitives and slaughtered them.


Attack of the Persian scythed chariots

Darius now launched his chariots at those troops under Alexander's personal command; many of the chariots were intercepted by the

and other javelin-throwers posted in front of the Companion cavalry. Those chariots who made it through the barrage of javelins charged the Macedonian lines, which responded by opening up their ranks, creating alleys through which the chariots passed harmlessly. The Hypaspists and the armed grooms of the cavalry then attacked and eliminated these survivors.


Alexander's decisive attack

As the Persians advanced farther and farther to the Greek flanks in their attack, Alexander slowly filtered in his rear guard. He disengaged his Companions and prepared for the decisive attack. Behind them were the guard's brigade along with any phalanx battalions he could withdraw from the battle. He formed his units into a giant wedge, with him leading the charge. The Persian infantry at the center was still fighting the phalanxes, hindering any attempts to counter Alexander's charge. This large wedge then smashed into the weakened Persian center, taking out Darius' royal guard and the Greek mercenaries. Darius was in danger of being cut off, and the widely held modern view is that he now broke and ran, with the rest of his army following him. This is based on Arrian's account:
For a short time there ensued a hand-to-hand fight; but when the Macedonian cavalry, commanded by Alexander himself, pressed on vigorously, thrusting themselves against the Persians and striking their faces with their spears, and when the Macedonian phalanx in dense array and bristling with long pikes had also made an attack upon them, all things together appeared full of terror to Darius, who had already long been in a state of fear, so that he was the first to turn and flee.

Alexander could have pursued Darius at this point. However, he received desperate messages from Parmenion (an event that would later be used by

and others to discredit Parmenion) on the left. Parmenion's wing was apparently encircled by the cavalry of the Persian right wing; being attacked from all sides, it was in a state of confusion. Alexander was faced with the choice of pursuing Darius and having the chance of killing him, ending the war in one stroke but at the risk of losing his army, or going back to the left flank to aid Parmenion and preserve his forces, thus letting Darius escape to the surrounding mountains. He decided to help Parmenion, and followed Darius later. While holding on the left, a gap had opened up between the left and center of the Macedonian phalanx, due to Simmias' brigade of pezhetairoi being unable to follow Alexander in his decisive attack, as they were being hard-pressed. The Persian and Indian cavalry in the center with Darius broke through. Instead of taking the phalanx or Parmenion in the rear, however, they continued towards the camp to loot. They also tried to rescue the Queen Mother,

, but she refused to go with them. These raiders were in turn attacked and dispersed by the rear reserve phalanx as they were looting. What happened next was described by Arrian as the fiercest engagement of the battle, as Alexander and his companions encountered the cavalry of the Persian right, composed of Indians, Parthians and "the bravest and most numerous division of the Persians", desperately trying to get through to escape. Sixty Companions were killed in the engagement, and

, Coenus and Menidas were all injured. Alexander prevailed, however, and Mazaeus also began to pull his forces back as Bessus had. However, unlike on the left with Bessus, the Persians soon fell into disorder as the Thessalians and other cavalry units charged forward at their fleeing enemy.


Aftermath

After the battle, Parmenion rounded up the Persian baggage train while Alexander and his bodyguard pursued Darius. As at

, substantial loot was gained, with 4,000 talents captured, the King's personal chariot and bow and the war elephants. It was a disastrous defeat for the Persians and one of Alexander's finest victories. Darius managed to escape by horseback with a small corps of his forces remaining intact. The Bactrian cavalry and Bessus caught up with him, as did some of the survivors of the Royal Guard and 2,000 Greek mercenaries. At this point, the

was divided into two halves—East and West. On his escape, Darius gave a speech to what remained of his army. He planned to head further east and raise another army to face Alexander, assuming that the Greeks would head towards

. At the same time he dispatched letters to his eastern satraps asking them to remain loyal. The satraps, however, had other intentions. Bessus murdered Darius before fleeing eastwards. When Alexander discovered Darius murdered, he was saddened to see an enemy he respected killed in such a fashion, and gave Darius a full burial ceremony at Persepolis, the former ceremonial capital of the Persian Empire, before angrily pursuing Bessus, capturing and executing him the following year. The majority of the remaining satraps gave their loyalty to Alexander and were allowed to keep their positions. The Achaemenid Persian Empire is traditionally considered to have ended with the death of Darius.
