The Ancients – The Fall of Persia | Alexander the Great
Aired: February 19, 2026 | Host: Tristan Hughes | Guest: Dr. Adrian Goldsworthy
Episode Overview
This episode, part three in a special series on Alexander the Great, covers Alexander’s relentless campaign through the Persian Empire following the pivotal Battle of Issus. The discussion centers on his legendary sieges at Tyre and Gaza, his reception in Egypt, the founding of Alexandria, the decisive Battle of Gaugamela, the dramatic entry into Babylon, and the collapse of Persian resistance, culminating in the deaths of both Darius III and the usurper Bessus. Dr. Adrian Goldsworthy, acclaimed historian and author of Philip and Alexander, Kings and Conquerors, returns to discuss how Alexander’s victories not only transformed the ancient world but also redefined the concept of empire and kingship.
Key Discussion Points and Insights
1. State of Play after Issus
(06:29–09:00)
- Alexander’s Position: By late 333 BC, Alexander is only 23, commanding a vast territory from Macedonia and Greece to Asia Minor, yet remains far from the Persian heartlands.
- Persian Resistance: Despite defeating Darius III at Issus, the Persian Empire remains a formidable adversary, possessing vast resources and a persistent naval threat in the Aegean.
- Internal Greek Politics: Greek mercenaries and exiles continue to fight for Persia, with cities like Sparta contemplating resistance to Macedonian dominance.
“He’s still the pygmy fighting against the giant... no matter how brave and skilled he is, the odds are against him.” – Dr. Adrian Goldsworthy (08:33)
2. The Siege of Tyre – Apex of Greek Siegecraft
(11:08–17:36)
- Tyre’s Strategic Importance: A heavily fortified island city in Phoenicia, Tyre stands as a key maritime power.
- Engineering Feats: Alexander’s army constructs a monumental mole to link Tyre to the mainland after initial efforts are destroyed by defenders. The siege lasts eight months, requiring advanced siege engines, floating towers, and naval assaults.
- Turning Point: As more Phoenician and Cypriot fleets defect to Alexander, he gains naval supremacy, allowing him to encircle Tyre.
- Brutality of Conquest: On capturing the city, Alexander enacts harsh retribution, killing or enslaving much of the population, especially targeting elites.
“Alexander isn’t waiting for them to run out of food and surrender. He storms the place in the end... far more formidable than anything his army has faced.” – Dr. Goldsworthy (12:42)
“He makes them, or I’m coming in and killing you.” – Dr. Goldsworthy (16:00)
- Symbolic Closure: Alexander sacrifices to Heracles, dedicating captured siege equipment as offerings.
3. The Siege of Gaza and Path to Egypt
(18:27–20:48)
- Gaza: Facing different challenges (sandy, tunnel-prone terrain), Alexander employs mining tactics against determined Persian defenders. The siege lasts two months and Alexander is wounded.
- Pattern of Relentless Victory: These time-consuming sieges solidify Alexander’s reputation for persistence, but delay his advance, allowing Darius more time to rebuild.
4. The Egyptian Interlude – Diplomacy and Divinity
(22:30–29:43)
- Egypt’s Surrender: The Persian governor yields without resistance; Egyptians, resentful of Persian rule, welcome Alexander as liberator.
- Respect for Local Customs: Alexander presents himself as a legitimate pharaoh, honoring local religious traditions.
“This is one of the greatest diplomatic successes, where he goes in and just people join him...” – Dr. Goldsworthy (23:49)
- Foundation of Alexandria (25:24–26:26): Alexander orders the construction of his eponymous city—destined to become the Hellenistic world’s intellectual center.
- Visit to Oracle of Ammon at Siwa (26:37–29:43): Alexander’s desert journey to consult the oracle cements stories about his divine parentage and foreshadows later claims to divinity.
5. On the Road to Babylon – The Final Confrontation with Darius
(29:43–35:57)
- March Northward: Following the Euphrates and Tigris, Alexander maneuvers his army through difficult terrain. Ancient sources allow precise dating thanks to Babylonian astronomical records.
- Darius’ Preparations: At Gaugamela, Darius assembles a massive force, including cavalry, elephants, and scythed chariots, and engineers the battlefield for his chosen tactics.
6. The Battle of Gaugamela – Decisive Victory
(36:41–44:41)
- Tactical Innovation: Alexander refuses to accept a negotiated peace or attack at night, opting for a head-on, daylight confrontation that maximizes psychological effect.
- Battle Dynamics: Alexander’s famed maneuvering opens gaps in the Persian line. His phalanx and companion cavalry disrupt Darius’ chariot onslaughts. In the chaos, Darius flees, and his army collapses.
“This is the battle where he unequivocally is at the head of the Royal Squadron... and steams straight towards the gap...” – Dr. Goldsworthy (41:23)
- Aftermath: Darius' credibility as great king is shattered. Alexander’s path to Babylon is open.
7. Into Babylon, Susa, and the Heartland of Persia
(45:20–49:35)
- Babylon’s Reception: Alexander is welcomed as king. His clemency and respect for local customs encourage Babylonian acceptance.
- Seizure of Wealth: With the imperial treasuries now under Macedonian control, Alexander gains resources for further campaigns.
“It’s the same sort of thing he does in Egypt... I will be a good king by your standards.” – Dr. Goldsworthy (49:16)
- Onwards to Susa: Alexander is struck by the opulence and architectural splendor of the Persian palaces, further cementing his sense of conquest.
8. The Symbolism of Persepolis – Vengeance Realized
(56:59–60:04)
- The Burning of Persepolis: Alexander destroys the royal palace—deliberately or impulsively—in a symbolic act of retribution for the Persian destruction of Athens.
- Cultural Impact: This act marks the definitive end of Achaemenid royal power and projects Alexander’s new dominance.
“It probably is deliberate... such a clear message. And again, it’s humiliating to Darius.” – Dr. Goldsworthy (59:35)
9. Pursuit and Political Upheaval – Darius’ End and the Fall of Bessus
(61:10–74:01)
- Pursuit of Darius: Darius flees east; a coup led by the satrap Bessus ends in his murder. Alexander adopts the role of avenger, pursuing Bessus as the regicide and new pretender.
- Dissension within the Ranks: The Philotas Affair – Philotas, son of Parmenion (Alexander’s key general), is implicated in a conspiracy and executed; Parmenion is assassinated to prevent potential rebellion.
- Transition to the East:
- Bactria submits to Alexander, Bessus is captured and brutally executed.
- The army’s mission becomes increasingly unclear, causing a rise in internal suspicions and dissent.
“How do you keep the relationship of a king and his companions...? Alexander becomes suspicious of a plot... and he is condemned and executed.” – Dr. Goldsworthy (68:11)
10. Closing Reflections and What’s Next
(74:01–75:12)
- Legacy and Further Challenges: As Alexander’s army pushes deeper into Central Asia, the nature of their struggle changes—less monumental battles, more guerrilla resistance, and a shifting sense of purpose.
- Foreshadowing: The campaign's most grueling phase lies ahead in Afghanistan and India, challenging both Alexander’s leadership and the resilience of his increasingly weary troops.

Summary
In this episode, The Ancients delves into the most dynamic phase of Alexander’s conquests – illustrating the drive, adaptability, and psychological acuity that earned him the epithet "the Great." From feats of engineering at Tyre to psychological warfare at Gaugamela, Alexander proves as astute a statesman as he is a battlefield tactician. He shapes the Middle East with both violence and diplomacy, yet as the empire expands, the limits of footsore armies, cultural tensions, and the enigma of power loom ever larger. The next and final installment promises an even more arduous journey through Afghanistan and India, and the poignant final chapters of Alexander’s life and legend.
“Alexander spends most of his life fighting... the big battles have happened. You’ve got one more to come in India, but otherwise, that’s it. But he keeps on fighting, and he’s wounded more dangerously and more times in this later period than he has been before.”
– Dr. Adrian Goldsworthy (75:12)
Stay tuned for the finale: Alexander’s campaigns into India, the brutal endgame, and his untimely death in Babylon.
