Battle of The Granicus - The Battle

The Battle

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 Greek 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 Greeks 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. 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". («Ἀλέξανδρος Φιλίππου καὶ οἱ Ἕλληνες, πλὴν Λακεδαιμονίων, ἀπὸ τῶν βαρβάρων τῶν τὴν Ἀσίαν κατοικούντων»-"Alexandros Philippou kai hoi Hellēnes plēn Lakedaimoniōn apo tōn barbarōn tōn tēn Asian katoikountōn").

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. 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.
