Alexander the Great

King of Macedon & Military Commander

Start herePlutarch, Life of AlexanderBegin with chapter 1, where Plutarch says he is writing lives, not histories, then read the boyhood chapters on Bucephalas and Aristotle. A short, lively way in; it repays checking against Arrian.Read Plutarch’s Life

Alexander left no book, and no memoir. The histories we can read were written centuries after his death from eyewitness accounts that are now lost. Read side by side, they show a commander of unusual technical and logistical imagination, and a conquest that razed cities, sold their people into slavery and killed his own friends. Start with Plutarch, who says plainly that he is writing a life, not a history.

331–330 BC

Gaugamela and the palaces of Persia

Darius chose the ground for the next battle, at Gaugamela, on a plain some distance from Arbela. Arrian gives the Persian reasoning: Darius had been persuaded that Issus was lost because the field was too narrow, so the plain was levelled for scythed chariots and cavalry. Arrian also preserves Alexander’s answer in his dispositions. Behind the front stood a second line, ordered to face about if the Persians got round the flanks. Detachments of archers and Agrianian javelin men were posted at an angle to the line, and the mercenary cavalry in front of the right wing had orders to strike the flank of anyone who rode round it. Light troops stood before the Companion cavalry to meet the chariots, and men opened their ranks to let some pass through, where grooms and guards dealt with them.

On 1 October 331 Alexander led his right obliquely farther to the right, almost off the cleared ground. Darius, afraid his chariots would be useless on rough ground, sent horsemen to ride round and stop the movement. As more Persian cavalry left the line to join that fight, a gap opened. Alexander formed the Companions and part of the phalanx into a wedge and drove through it toward Darius, who, Arrian says, was the first to turn and flee. Arrian records Darius’s motive but not Alexander’s; what his narrative shows is a march that threatened to take the battle off the prepared field and pulled Persian horsemen out of their line.

Victory turned the problem from fighting to governing. At Babylon Alexander ordered the temples Xerxes had destroyed to be rebuilt and made Mazaeus, a Persian who had commanded against him at Gaugamela, governor, with a Macedonian general over the garrison and a separate official collecting revenue. At Persepolis in 330 he appointed another Persian governor, then burnt the royal palace. Arrian says Parmenio advised against destroying what was now Alexander’s own property; Alexander answered that it was revenge for the Persian burning of Athens; and Arrian judged the act neither prudent nor real punishment of the Persians who had done it. Diodorus, from a different tradition, describes a drunken victory feast at which the Athenian Thaïs proposed the fire. The sources do not reconcile the two versions.

326–324 BC

The army turns back

In 326 Alexander fought and defeated the Indian king Porus at the Hydaspes river. At the Hyphasis that July the army would go no farther. Arrian gives the moment to the officer Coenus, who broke a long silence to speak for exhausted men; the speech is Arrian’s composition, as ancient historians’ speeches usually were. Alexander withdrew to his tent for three days. When the army did not change its mind and the sacrifices for crossing proved unfavourable, he announced the return.

In 325 he sent the fleet along the coast under Nearchus and led much of the army west through the Gedrosian desert. Nearchus, quoted by Arrian, gives two reasons: to outdo the legendary failures of Cyrus and Semiramis there, and to keep supplies near the fleet. The march went inland, by night, far from water. When starving guards broke the royal seal on grain meant for the ships, Alexander pardoned them once he learned why. Heat and thirst destroyed a great part of the army and most of its animals.

At Susa in 324 Alexander married Darius’s eldest daughter and, according to Aristobulus, a daughter of an earlier Persian king, and gave about eighty of his Companions brides from Persian, Median and Bactrian noble families, all in Persian-style ceremonies. Then 30,000 young Asians, trained and armed in the Macedonian way and called the Epigoni, “successors,” arrived. Arrian calls the weddings popular in one passage and in another says most Macedonians resented them, along with the Epigoni and the king’s Median dress. At Opis, when Alexander announced the discharge of veterans unfit for service, the army shouted that he should send them all home and campaign with his father Ammon. He had thirteen men taken away for execution, shut himself in for two days, then began giving Persians the army’s commands. The Macedonians threw down their weapons at the palace gates and begged to be let in. The reconciliation ended in a banquet at which, Arrian says, Alexander prayed for harmony and shared rule between Macedonians and Persians.

That autumn his closest friend Hephaestion died of fever at Ecbatana. Arrian notes that accounts of Alexander’s grief varied with each writer’s goodwill or envy toward the two men. Plutarch says the doctor was crucified, music was silenced, and the Cossaean people were attacked and slaughtered as “an offering to the shade of Hephaestion.” The sources repeat the comparison with Achilles and Patroclus; they do not settle what kind of relationship it was.
