- Lucas: So we've talked a lot about Athens and Sparta, but I think it's time we finally tackle the elephant in the room — Alexander the Great. Specifically, I want to focus on one of his most incredible campaigns: the siege of Tyre in 332 BCE. It's a story that really shows you how Alexander operated. Lucas: After he'd already crushed Darius III at Issus, Alexander could have just marched straight into Persia. But instead, he turned south along the Mediterranean coast. He needed to secure his supply lines and neutralize the Persian fleet, which was still a real threat. The key was the island city of Tyre, in modern-day Lebanon. Luna: Tyre — wasn't that the city that was basically impossible to take? Lucas: Exactly. Tyre was built on an island about half a mile off the coast, with walls that rose 150 feet straight out of the sea. It had two harbors, one on the north and one on the south, and a powerful navy. Alexander knew he couldn't leave a hostile Tyre at his back, so he had to take it. Lucas: But he had no siege experience on water. So he came up with a plan that was audacious even by his standards: he would build a mole, a causeway, from the mainland to the island, using rubble and timber. The old city of Tyre on the coast provided plenty of material. They even tore down buildings for stones. Luna: A causeway in the middle of the sea — that's insane. Lucas: It was an engineering nightmare. The water got deeper as they got closer, and the Tyrians weren't just sitting there. They sent out fire ships, they showered the workers with arrows and catapult fire. Alexander had to build two siege towers on the mole, but the Tyrians loaded a ship with combustible materials and set it on fire, ramming the towers and burning them down. Lucas: So Alexander had to change tactics. He realized he needed control of the sea to isolate Tyre completely. He gathered a fleet from the Phoenician cities he'd already subdued — Sidon, Byblos, Aradus — and even some from Cyprus. In total, he had about 200 ships. Luna: So the Phoenician cities, which had supplied the Persian fleet, now sided with Alexander? Lucas: Right. That was a huge diplomatic win. With his new fleet, Alexander blockaded both harbors of Tyre. He also started building a new, wider mole, and this time he stationed ships alongside it to protect the workers. He brought up siege engines on the mole and on ships — including battering rams mounted on floating platforms. Lucas: But the Tyrian walls were incredibly thick, especially facing the mole. So Alexander sent a group of ships with rams to the south wall, which was weaker. They managed to breach a section, but the Tyrians quickly repaired it. Meanwhile, Alexander's siege engineer, a man named Diades, designed massive rams and catapults. Luna: Diades — I've heard he was like the genius of ancient siege warfare. Lucas: He was. He worked for Philip and Alexander, and he wrote a treatise on siege engines. At Tyre, he came up with some wild designs. But even with all that, the siege dragged on for seven months. Finally, Alexander launched a two-pronged attack: a diversion at one harbor while he concentrated his best troops — the hypaspists, his elite infantry — at a section of the wall that had been weakened. Luna: Hypaspists — those are the shield-bearers, right? Lucas: Yes, they were the elite of the Macedonian phalanx. Alexander led the assault himself. They managed to storm the city, and the fighting was brutal. Alexander was furious at the resistance — the Tyrians had killed some of his men in parley and even crucified prisoners on the walls. When the city fell, 8,000 Tyrians were killed, and 30,000 were sold into slavery. Alexander spared the king and a few nobles. Lucas: The siege of Tyre was a turning point. It showed that Alexander could overcome any obstacle, and it sent a message to every other city: surrender or face annihilation. It also neutralized the Persian navy, because the Phoenician and Cypriot ships now belonged to Alexander. After that, he could march into Egypt and then Persia without worrying about his rear. Luna: So the siege really made his entire Asian campaign possible. Lucas: Absolutely. Without Tyre, Alexander's supply lines would have been cut, and he could have been trapped in Asia. It's one of those what-if moments. But it also shows the cost of his ambition — the sheer destruction, the lives lost. And the causeway he built? It's still there today. The land that connected Tyre to the coast gradually accumulated into a permanent isthmus. So you can literally walk to what used to be an island. Luna: Wow. So Alexander literally changed the geography of the Mediterranean. Lucas: In a way, yes. The old Tyre is now a peninsula. It's a lasting monument to his determination. But it's also a sobering reminder of the human cost of his conquests. The Tyrians fought with incredible bravery, but they were up against a force that simply refused to accept defeat. Luna: Thanks, Lucas. That was a great deep dive into a battle I knew nothing about. Lucas: Glad you enjoyed it. Next time, maybe we'll talk about what happened to Tyre and Alexander's other conquests in the years after his death.
