Transcript
- Lucas: Before we tackle Tyre, let's set the stage: it's early 332 BCE. Alexander has just crushed Darius at Issus, but instead of chasing him east, he turns south along the Mediterranean coast. Why? Because the Persian fleet, mostly Phoenician and Cypriot ships, could still strike his rear and cut his supply lines. He needs to neutralize their ports one by one. Luna: So he's systematically taking out their naval bases. Lucas: Exactly. He takes Byblos and Sidon without a fight — they surrender. But Tyre, the most powerful Phoenician city, refuses. They're confident because their city is on an island, half a mile offshore, with walls that rose right up from the sea. Alexander has no navy of his own at this point — at least, not one that matters. Lucas: So he decides to build a causeway. A mole, or what the Greeks called a choma, from the mainland to the island. The water is shallow near the coast, but it deepens quickly. He uses rubble from the abandoned mainland city of Old Tyre — stones, timber, and earth — and his soldiers start piling it into the sea. Luna: That sounds like an engineering nightmare. Lucas: It was. The Tyrians didn't just watch. They sent out ships to harass the workers, firing arrows and catapult bolts. So Alexander hung leather curtains to protect his men. Then the Tyrians sent a fireship — an old vessel packed with dry brush, pitch, and sulfur — drifting into the causeway. It set the Macedonian siege towers alight and destroyed much of the work. Lucas: By now, Alexander has managed to gather a fleet — about 200 ships from his newly acquired Phoenician and Cypriot allies. With that, he blockades Tyre's harbors. The northern harbor is blocked by a squadron under his admiral Hephaestion, and the southern by the Cyprian contingent. Luna: So he's using their own ships against them. Lucas: Exactly. But the Tyrians still have a trick or two. They send divers — trained swimmers — to cut the anchor ropes of Alexander's ships, setting them adrift. Alexander has to replace the ropes with chains. And they built a new, hidden exit from their harbor to launch surprise attacks. It was a contest of constant adaptation. Lucas: The causeway finally reaches the walls after several months. But the walls facing it are massive — over 150 feet high. Alexander mounts siege towers on ships and tries to breach the walls from the sea, but the Tyrians respond by heaving down boulders and pouring burning sand that gets under armor and burns skin. Luna: Burning sand? That's brutal. Lucas: It was. They'd heat sand in bronze shields and scatter it onto the attackers. It worked like a horror weapon. But Alexander persisted. He found a weak spot on the south side of the island, where the wall was thinner and the water shallower. He assembled a joint attack — battering rams on ships, and a simultaneous assault on the causeway. Lucas: On the day of the assault, July 332 BCE, Alexander's rams finally breach a section of the wall. He leads his hypaspists — elite infantry — through the gap. The Tyrians fight desperately in the streets, but they're overwhelmed. The Macedonians show no mercy: 8,000 Tyrians are killed, and about 30,000 are sold into slavery. Only the king and high officials are spared, and the Sidonian contingent is allowed to leave, having been forced to serve. Luna: That's a savage ending. Lucas: It was, by any standard. But from a strategic perspective, it worked. With Tyre destroyed, the Persian fleet lost its main base. The remaining Phoenician ships either defected or became useless. Alexander could now march into Egypt without worrying about his rear. And he did — just a few months later. Luna: I've read that Alexander showed unusual cruelty at Tyre, compared to his usual policy of clemency. Lucas: Yes, it's a notable exception. He had offered terms twice — first a peaceful surrender, then a truce — but the Tyrians killed his envoys. In ancient warfare, that was a grave insult, and it often justified a harsh reprisal. Also, Alexander needed to send a message: resistance would be met with annihilation. He couldn't afford to leave any stronghold undefeated behind him. Lucas: The siege of Tyre also showcased Alexander's flexibility. He wasn't just a hammer — he could build a causeway, command a fleet, and coordinate combined operations. And the Tyrians, for their part, showed incredible ingenuity. They invented new defensive technologies — the burning sand, the anchor-cutting divers, the fireship. In a way, it was a siege that pushed military engineering forward on both sides. Luna: It's amazing that the causeway is still there — it turned Tyre from an island into a peninsula. Lucas: Exactly. The silting over centuries has connected it permanently. So in a sense, Alexander's siege reshaped the geography. The modern city of Tyre sits on what was once the causeway and the island. You can still see the ruins of the ancient walls underwater. Lucas: Before we move on, I want to mention something about how we keep this show going. We deliberately don't run ads on these episodes. That's a choice we've made from the start, because we think history should be told without interruptions. If you appreciate that approach and want to support it, there's a link in the show notes — buy me a coffee dot com slash fexingo. It's a simple way to help us keep doing this. Luna: Yeah, it's really listener support that makes this possible. We're grateful for that. Lucas: So back to Tyre. One of the things I find most interesting about this siege is how it's recorded. Our main sources — Arrian, Curtius Rufus, and Diodorus Siculus — all differ on details. Arrian says Alexander got 200 ships from his allies; Diodorus says 80 from Sidon alone. The numbers vary, but the core story holds: it was a long, brutal, and decisive victory. Luna: How reliable are those sources? Lucas: They were all writing centuries after the events, using earlier accounts that are now lost. So we have to be cautious. But there's also archaeological evidence: remains of the causeway, traces of the siege works, and the layout of the island. It corroborates the general picture, even if the exact casualty numbers are uncertain. Lucas: The siege of Tyre also had a cultural impact. The city had a famous temple to Melqart, a Phoenician god identified with Heracles by the Greeks. Alexander claimed descent from Heracles, and he wanted to sacrifice there. The Tyrians refused, which added a religious dimension to the conflict. After the fall, Alexander did perform the sacrifice — a symbolic claim to legitimacy. Luna: So it was personal for him too. Lucas: In his mind, yes. He saw himself as carrying out a mission, almost a divine duty. And Tyre stood in his way. Once it fell, the path to Egypt and the oracle of Siwa — where he'd be declared son of Zeus — was open. Tyre was the hinge that swung the door to his divinity. Lucas: A final note: the siege of Tyre is often overshadowed by Gaugamela or Issus, but it was arguably as important. Without Tyre, Alexander could not have secured the Mediterranean. And his success there demonstrated a mastery of siegecraft that would be studied for centuries. It's a testament to human determination on both sides. Luna: And a sobering reminder of what war can do. Lucas: Absolutely. Thanks for joining me on this deep dive.
