The battle plan

Alexander The Great planned to hold his forces of cavalry on the right flank, while his trained infantry went left, forcing Darius to go through a river. Alexander then planned to attack after Darius was thoroughly stuck.

Background

During the two years after the Battle of Issus
Battle of Issus

The Battle of Issus occurred in southern Anatolia, in November 333 BC.

 rivers without any opposition. Darius was building up a massive army, drawing men from the far reaches of his empire. He planned to use numbers to crush Alexander, and according to some contemporary historians he gathered around 100,000 men. Darius also picked a flat plain for a battlefield so Alexander would have no advantages in terrain, and allowing Darius to use his vast horde more effectively.

The motives

On the eve of battle Alexander's generals were of the view that to counter the overwhelming advantage in numbers of the Persians a night attack should be launched. Alexander is said to have dismissed the notion explaining that as he was no ordinary general he would not act like one. As it turned out Alexander's timing of battle was right. Darius, fearing a night attack, kept his army awake and on alert for the whole night, while Alexander's were more rested.

n, and Macedonian light cavalry. The mercenary cavalry was divided into two groups, with the veterans being stationed on the flank of the right, and the rest being put in front of the Agrians and Macedonian archers which were stationed next to the phalanx. Parmenion was stationed on the left with the Thessalian, Greek mercenary, and Thracian cavalry units. There they were to pull off a holding maneuver while Alexander landed the decisive blow from the right.

On the right-center of the formation were Cretan mercenaries. Behind them was a group of Thessalian cavalry under Phillip, and Achaian mercenaries. To their right was another part of the allied Greek cavalry. From there came the phalanx, which was placed into a double-line. Outnumbered over 5:1 in cavalry, with their line surpassed by over a mile, it seemed inevitable that the Macedonians would be flanked by the Persians. The second line were given orders to deal with any flanking units should the situation arise. This second line consisted of mostly 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 degree angles to lure the Persian cavalry to attack. While the phalanxes battled the Persian infantry, which included both regular soldiers and Immortals, 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 used an unusual strategy which has been duplicated only a few times throughout history. His plan was to draw as much of the Persian cavalry as possible to the flanks. The purpose of this was to create a gap within the enemy line where a decisive blow could then be struck at Darius in the center. This required almost perfect timing and maneuvering, and the Great King himself to act first. Alexander 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's hand was forced, and he attacked.

Darius now launched his chariots, some of which were intercepted by the Agrianians
Agrianes

The Agrianians a Paionian tribe, who chiefly inhabited the area of north of the Thracian Maedi tribe in Macedonia and Thrace. They were crack Javelin_%28weapon%29#Ancient_Greece throwers and the elite unit of Alexander the Great light infantry, who fought under the command of Attalus ....
. It is said that the Macedonian army had trained for a new tactic to counter these devastating chariots if they ran into their ranks. The first lines would step aside, opening a gap. The horse would refuse to run into the lances of the front ranks, and enter the "mouse trap", only to be stopped by the lances of the rear ranks. The charioteers and their horses could then be killed at leisure. The chariots were rendered useless.

Alexander's decisive attack

As the Persians moved farther and farther to the Macedonian flanks in their attack, Alexander slowly filtered in his rear-guard. Alexander disengaged his Companions, and prepared for the decisive attack on the Persians. Leading the way, he formed his units into a giant wedge, with him leading the charge. Behind them were the guards brigade along with any phalanx battalions he could withdraw from the battle. These were follow-up light troops. Alexander took most of his cavalry and moved parallel to Darius's front lines, heading off of the prepared battlefield. In doing so, Darius ordered his cavalry in the front lines to block Alexander's force. Unbeknownst to Darius, Alexander hid a force of peltasts (light infantry armed with slings, javelins, and shortbows) behind his horsemen and Alexander slowly sent his force into an angle, heading toward the Persian host, until finally a gap opened between Bessus's left and Darius's center and Alexander sent in his cavalry force to drive down the gap in the Persian line in a wedge formation. At the same time, the peltasts engaged the cavalry, so as to keep them from riding back to engage Alexander's charging cavalry. The infantry at the center was still fighting the phalanxes, hindering any attempts to counter Alexander's charge.

Battle Gaugamela Decisive
This large wedge then smashed right into the weakened Persian center, taking out Darius's royal guard, and the Greek mercenaries. Bessus on the left, now cut off from Darius, and fearing he would be struck with this wedge, began to pull back his forces. Darius was in danger of himself 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 (Anabasis 3.14):

"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."


A less common view is that Darius's army was already broken when Darius ran, and is supported by an astronomical diary from Babylon written within days of the battle:

The twenty-fourth [day of the lunar month], in the morning, the king of the world [i.e., Alexander] [erected his] standard [lacuna]. Opposite each other they fought and a heavy defeat of the troops [of the king he inflicted]. The king [i.e., Darius], his troops deserted him and to their cities [they went]. They fled to the land of the Guti.


The left flank

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

 and others to discredit Parmenion) on the left. Alexander was faced with the choice of pursuing Darius, but losing his army, or going back to the left flank to aid Parmenion and preserve his forces. In the end, he made the decision to help Parmenion, and follow Darius later.

While holding on the left, a gap had also opened up between the left and center of the Macedonian line. The Persian and Indian cavalry units stationed in the center with Darius broke through. Instead of taking the phalanx or Parmenion in the rear, however, they continued on towards the camp to loot. They also tried to rescue Queen Mother Sisygambis

Sisygambis was the daughter of king Artaxerxes II Memnon, who married Arsames of Ostanes and was the mother of Darius III of Persia, whose reign was ended during the wars of Alexander the Great....
 but she refused to go with them. On their way back, the Indians slew over 60 of the Companion cavalry.

Meanwhile, as the center and Darius broke, 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 own bodyguard chased after Darius in hopes of catching up. As at Issus

The Battle of Issus occurred in southern Anatolia, in November 333 BC.

Darius had managed to escape the battle with a small core of his forces remaining intact. The Bactrian cavalry and Bessus managed to catch up with him, as did some of the survivors of the Royal Guard and 2,000 Greek mercenaries.
