The Battle of the Granicus River in May 334 BC was the first of three major battles fought between Alexander the Great and the Persian Empire. Fought in Northwestern Asia Minor, near the site of Troy, it was here that Alexander defeated the forces of the Persian satraps of Asia Minor, including a large force of Greek mercenaries led by Memnon of Rhodes.
The battle took place on the road from Abydos to Dascylium (near modern day Ergili, Turkey), at the crossing of the Granicus River (modern day Biga Çayı).

Following the assassination of Alexander's father, Philip II of Macedon, and the subsequent consolidation of Alexander's Macedonian positions, he set out into Asia in 334 BC.
He crossed the Hellespont from Sestos to Abydos, and advanced up the road to Dascylium, which was the capital of the Satrapy of Phrygia. The various satraps of the Persian empire gathered with their forces at the town of Zelea and offered battle on the banks of the Granicus River. Memnon suggested a scorched-earth policy of burning the grain and supplies and retreating in front of Alexander, but his suggestion was rejected by the commanding satraps.
Arrian, Diodorus, and Plutarch all mention the battle, with Arrian providing the most detail. The Persians placed their cavalry in front of their infantry, and drew up on the right (east) bank of the river. Historians differ significantly on the effectiveness of the Persian dispositions. Some consider it a tactical mistake on the Persian side, others feel it was an attempt to take advantage of their superior number of cavalry, while Sir William Tarn felt "the Persian leaders had in fact a very gallant plan; they meant if possible to strangle the war at birth by killing Alexander."
According to Alexander's biographer Arrian, Alexander's army met the Persians on the third day of May from Abydos. Alexander's second-in-command, Parmenion suggested crossing the river upstream and attacking at dawn the next day, but Alexander attacked immediately. This tactic caught the Persians off guard. The Macedonian line was arrayed with the heavy Phalanxes in the middle, and cavalry on either side. Alexander was with the Companions on the right flank. The Persians expected the main assault to come from Alexander's position and moved units from their center to that flank.
The battle started with a cavalry and light infantry feint from the Macedonian left, from Parmenion's side of the battle line. The Persians heavily reinforced that side, and the feint was driven back, but at that point, Alexander led the horse companions in their classic wedge-shaped charge, and smashed into the center of the Persian line. The Persians countercharged with a squadron of nobles on horse, and accounts show that in the melee, several high-ranking Persian nobles were killed by Alexander himself or his bodyguards, although Alexander was stunned by an axe-blow from a Persian nobleman named Spithridates. Before the noble could deal a death-blow, however, he was himself killed by Cleitus the Black. Alexander quickly recovered.
The Macedonian cavalry then turned left and started rolling up the Persian cavalry, which was engaged with the left side of the Macedonian line after a general advance. A hole opened in the recently vacated place in the battle line, and the Macedonian infantry charged through to engage the poor-quality Persian infantry in the rear. At this, and with many of their leaders already dead, both flanks of the Persian cavalry retreated, seeing the collapse of the center. The infantry also routed, many being cut down as they fled.
Total casualties for the Macedonians were between 300 and 400. The Persians had roughly 1,000 cavalry and 3,000 infantry killed, mostly in the rout. The Greek mercenaries, under the command of Memnon of Rhodes, who fought for the Persians, were abandoned after the cavalry retreat. They attempted to broker a peace with Alexander but to no avail. As a result, after the battle Alexander ordered his infantry, who until this point had played no role in the battle, to slaughter the mercenaries to a man. 18,000 mercenaries were killed and 2,000 enslaved and sent back to Macedonia in chains for hard labour. It is believed that Alexander had a strong majority of the mercenaries killed in fear of plague.[5] Also, Alexander sent 300 Persian armours to the Parthenon of Athens as an oblation to Athena, with this epigram: "Alexander, son of Philipp, and the Greeks, except of Lacedaemonians, from the barbarians who live in Asia". («Αλέξανδρος Φιλίππου και οι Έλληνες, πλην Λακεδαιμονίων, από των βαρβάρων των την Ασία κατοικούντων»-"Alexandros Philippou kai oi Ellines plin Lakedemonion apo ton barbaron ton tin Asia katoikounton").
That account of the battle is directly contradicted by Diodorus Siculus who states "When Alexander learned of the concentration of the Persian forces, he advanced rapidly and encamped opposite the enemy, so that the Granicus flowed between the encampments. The Persians, resting on high ground, made no move, intending to fall upon the foes as he crossed the river, for they supposed they could easily carry the day when the Macedonian phalanx was divided. But Alexander at dawn boldly brought his army across the river and deployed in good order before they could stop him. In return, they posted their mass of horsemen all along the front of the Macedonians since they had decided to press the battle with these. Memnon of Rhodes and satrap Arsamenes held the left wing each with his own cavalry; Arsites was stationed next with the horsemen from Paphlagonia; then came Spithrobates satrap of Ionia at the head of the Hyrcanian cavalry. The right wing was held by a thousand Medes and two thousand horsemen with Rheomithres as well as Bactrians of like number. Other national contingents occupied the centre, numerous and picked for their valour. In all, the cavalry amounted to more than ten thousand. The Persian foot soldiers were not fewer than one hundred thousand, but they were posted behind the line and did not advance since the cavalry was thought to be sufficient to crush the Macedonians.[6] The record of Arrian and Diodorus on the battle of Granicus can't be reconciled so historians usually prefer Arrian, although some revisionists try to reconcile the two accounts.
Historian Peter Green, in his 1974 book Alexander of Macedon, proposed a way to reconcile the account of Diodorus and Arrian. According to Green's interpretation, the riverbank was guarded by infantry, not cavalry, and Alexander's forces sustained heavy losses in the initial attempt to cross the river and were forced to retire. Alexander then grudgingly accepted Parmenion's advice and crossed the river during the night in an uncontested location, and fought the battle at dawn the next day. The Persian army hurried to the location of Alexander's crossing, with the cavalry reaching the scene of the battle first before the slower infantry, and then the battle continued largely as described by the Arrian and Plutarch accounts. Green accounts for the differences between his account and the ancient sources by suggesting that Alexander later covered up his initial failed crossing. Green devotes an entire appendix in support of his interpretation, taking the view that for political reasons, Alexander could not admit even a temporary defeat. Thus, the initial defeat was covered up by his propagandists, by a very heroic (and Homeric) charge into the teeth of an extremely poorly deployed enemy. However, Green freely admits this is a theory, and most still pick Arrian over Diodorus.
Alexander (purportedly) came close to dying in the battle. Mithridates, Rhoesaces, Spithridates and several other Persian leaders were killed, while Arsites fled and shortly after committed suicide in his satrapy. The Greek cities in Asia Minor fell to Alexander, and a beachhead was established so that further campaigns against the Persian empire could be accomplished. Darius III continued to leave the responsibility of battling against Alexander to his satraps and gave Memnon a commanding role over the navy and coastal areas. Not until the Battle of Issus would Darius decide to confront the Macedonian conqueror in person.
