The Conquests of Alexander

He named 20 cities after himself and one after his horse

Alexander the Great is supposed to have wept when he saw the size of what he had won, because there were no more worlds left to conquer.

His own record calls that line paraphrased, and probably not his at all.

Nobody who wrote a full account of Alexander's life ever met him. Arrian, Plutarch, and Curtius Rufus, the three fullest histories that survive, were all writing centuries after he died.

Everything spoken in his own words in what follows carries that warning, every time.

Scene 1Thebes, before the crossing

Philip the Second is two years dead, murdered by one of his own bodyguards, and several Greek cities have decided his son will not hold what his father built.

Alexander marches on Thebes first. When the city falls, six thousand people are killed and thirty thousand are sold into slavery.

No other Greek city rises against him again while he lives.

Scene 2Anatolia, three thirty four to three thirty three before the common era

In the spring, Alexander crosses the Hellespont with thirty seven thousand troops and one and a half million pounds of debt.

At the Granicus River in May, he leads the first cavalry charge himself and nearly dies. A Persian commander swings a sword at his head, and Cleitus the Black cuts the man's arm off before it lands.

Cleitus has just saved the life of the man who will kill him at a dinner table eight years later.

By November, Alexander meets Darius the Third at Issus, on a coastal plain too narrow for a Persian army of some hundred thousand men to use its size. Darius flees, leaving his mother, wife, and children behind.

Scene 3Tyre, Gaza, and Egypt, three hundred and thirty two before the common era

Tyre will not surrender, so Alexander spends seven months building a causeway half a mile long through open sea to reach the island city.

When Tyre falls, two thousand military age men are crucified along the beach and thirty thousand people are sold into slavery.

Gaza holds out two more months. Its commander, Batis, is dragged alive behind a chariot when the city falls.

Egypt opens its gates and welcomes him as a liberator from Persian rule. At the oracle of Siwa, the priests call him son of Ammon, and he never once says they are wrong.

Plutarch, writing about four hundred years after Alexander was dead, has him say this about Diogenes.

Alexander, as reported by Plutarch · Life of Alexander · c. 100 CE

“If I were not Alexander, I would wish to be Diogenes.”

Scene 4Gaugamela, the first of October, three hundred and thirty one before the common era

Darius gathers an army ancient writers put at two hundred and fifty thousand men. Modern historians think fifty to a hundred thousand is closer to the truth.

Alexander has forty seven thousand. He breaks the Persian center with a diagonal cavalry charge still studied in military academies two thousand years later.

Darius runs a second time. Within a year his own satrap, Bessus, murders him. Alexander hunts Bessus into Central Asia and has him executed.

Scene 5Maracanda, three hundred and twenty seven before the common era

Between Gaugamela and India, Alexander campaigns for three years through what is now Afghanistan, Uzbekistan, and Tajikistan. He marries Roxana, a Bactrian noblewoman, over the fury of his own officers.

At a drunken banquet in Maracanda, now Samarkand, he kills Cleitus the Black with a spear, in an argument over whether Philip or Alexander deserved more credit for the victories.

Cleitus is the man who cut off the arm reaching for Alexander's head at the Granicus. Alexander refuses food for three days afterward.

Curtius Rufus, a Roman writing about three hundred seventy years later, used one sentence for what Alexander had become.

Curtius Rufus · Historiae Alexandri Magni · c. 50 CE

“His body, panting with unquenchable thirst for blood, was now turning against his friends and generals.”

The man Cleitus had saved was gone. What was left killed him.

Scene 6The Hyphasis, and the road home, three hundred and twenty six to three hundred and twenty three before the common era

Alexander beats King Porus at the Hydaspes River in May, against two hundred war elephants his phalanx has never faced in that number. He wins, but eight years of marching, monsoon rain, and disease have used up his army's patience.

At the next river, the Hyphasis, his veterans refuse to go one step further east. Alexander sulks in his tent for three days, then turns the army around.

The march home through the Gedrosian Desert kills a quarter of his men, roughly fifteen thousand, to heat, thirst, and flash floods.

He reaches Babylon in three hundred and twenty three before the common era and dies on the tenth or eleventh of June, aged thirty two. His empire breaks apart within hours.

Five accounts

Five accounts of the same eleven years survive, and whether Alexander was a liberator or a catastrophe depends entirely on which side of the Hellespont a person was standing.

  1. Greco-Macedonian
  2. Persian / Achaemenid
  3. Indian / Paurava
  4. Modern Central Asian
  5. Revisionist / Anti-Heroic

The turn

Each account skips what would complicate it.

  1. Greco-Macedonian

    The Greek and Macedonian record calls the destruction the convention of siege warfare, and says far less about Thebes, Tyre, Gaza, and the burning of Persepolis, or the drinking and paranoia of the last years.

    From the record
    Genocidal sieges at Tyre, Gaza, and the Branchidae
    Destruction of Persepolis and its cultural treasures
    Alcoholism and increasingly erratic behavior in final years
    Forced deportation of Greek settlers to distant colonies
  2. Persian / Achaemenid

    The Persian account names every ton of silver Alexander carried off, and says less about the satraps who had already revolted against Darius before Alexander arrived, or the courtesy Alexander showed Darius's own captured family.

    From the record
    Internal weaknesses of the late Achaemenid state, including satrapal revolts
    Egyptian and Babylonian populations that welcomed Alexander as a liberator
    Persian imperial violence against subject populations (Ionian revolts, Egyptian rebellions)
    Alexander's respectful treatment of the Persian royal family
  3. Indian / Paurava

    The Indian account is built on an army that mutinied, and says little about the battle Alexander actually won at the Hydaspes, or the Greek coinage and city planning northwestern India kept using long after the Macedonians left.

    From the record
    Alexander's tactical victory at the Hydaspes
    Greek cultural contributions to Gandhara Buddhist art
    Taxila's voluntary submission to Alexander
    The lasting Hellenistic influence on northwestern Indian coinage and urban planning
  4. Modern Central Asian

    The Central Asian account, which names the guerrilla war in the most detail, says less about the Greco-Bactrian kingdoms it produced, kingdoms where a Greek king later became a Buddhist.

    From the record
    Genuine cultural exchange and artistic innovation in Greco-Bactrian period
    Greek contributions to urban planning, coinage, and administrative practices
    Voluntary adoption of Greek language and customs by some Central Asian elites
    The Milindapanha and Indo-Greek Buddhist patronage
  5. Revisionist / Anti-Heroic

    And the revisionist case, which spares him nothing, has the least interest in the library at Alexandria or the language the New Testament was later written in, both of which trace back to the same eleven years it condemns.

    From the record
    Genuine cultural achievements of the Hellenistic world Alexander initiated
    Alexander's tolerance of local religions and customs in conquered territories
    Real military innovation in combined-arms tactics and logistics
    The agency of conquered peoples who adopted Greek culture voluntarily

Close

He founded more than twenty cities across three continents, and named nearly all of them Alexandria, after himself.

On the bank of the Hydaspes he named one more. Bucephala, after the horse that had carried him into battle and died there, from wounds or from exhaustion. The ancient sources cannot agree on which.
