- Lucas: Welcome back to the network. If you've been stepping into history with us episode by episode, we’ve spent a lot of time looking at how Greek cities defended themselves against each other or against Macedonian kings. But today, I want to take you to the coast of modern-day Turkey, to the island of Rhodes, around 305 BC. Luna: It was right after Alexander died, wasn't it? Lucas: Exactly. The empire had fractured, and his generals were tearing it apart in what we call the Wars of the Diadochi. One of those generals, Antigonus Monophthalmus, wanted to control the Aegean Sea. He sent his son, Demetrius, to take the island. It was supposed to be a quick victory, but it turned into a six-month nightmare that changed how siege warfare would be done forever. Luna: How big was Demetrius's army? Lucas: Massive by ancient standards. He brought about twenty thousand infantry and four thousand cavalry, supported by a large fleet. The Rhodians, on the other hand, had maybe seven thousand foot soldiers and a handful of ships. They couldn’t fight him out at sea, so they decided to stay behind the walls and see if they could just outlast him. Lucas: The first thing Demetrius did was try to starve them out, blockading the harbor. But the Rhodians had plenty of grain stored up. So he switched to brute force. He started building siege towers, giant wooden structures covered in wet hides to resist fire, designed to tower over the city walls. Luna: Did the towers reach the top of the walls? Lucas: That was the idea. These towers were multi-storied beasts, some reaching over one hundred feet high. They carried catapults and ballistae on the upper decks to shoot down onto the defenders while infantry climbed ramps to walk onto the battlements. It was essentially a mobile fortress designed to swallow the city whole. Lucas: But the Rhodians had a trick. They realized that if the tower was taller than their wall, they could build a second wall inside the city, parallel to the first. When Demetrius’s engineers pushed their tower forward, the Rhodians would simply retreat behind this inner wall, leaving the attackers exposed to crossbow fire from above and below. Luna: So the towers became useless? Lucas: Mostly. And then Demetrius built something even bigger. Historians call it the Helepolis, or City-Taker. It was a massive siege engine on wheels, armored in iron plates, designed to smash through any wall in its path. It was a marvel of Hellenistic engineering, powered by hundreds of men turning cranks to move it forward. Lucas: The Rhodians responded by digging trenches filled with water in front of their walls. The heavy Helepolis sank into the mud, stuck fast. Then, when Demetrius tried to fill the trench with earth and rubble, the Rhodians used a clever counter-tactic. They built tall, narrow towers made of light wood, positioned behind the main wall. Luna: Light wood? That sounds risky. Lucas: It was deliberate. They dropped burning torches from these towers onto the pile of earth Demetrius’s men were shoveling. The earth caught fire, creating a wall of flame that prevented the besiegers from ever filling the gap. For months, the two sides just sat there, trading arrows and failing to gain ground. Lucas: Demetrius eventually got frustrated enough to launch a direct assault with scaling ladders. He brought in specialized troops, including a unit called the Elephas, which were actually elephants fitted with fighting towers. They marched toward the gates, intending to batter them down. Luna: Elephants in a Greek siege? Lucas: It was unusual, but not unheard of for the Diadochi. The problem was that the Rhodians had prepared holes in the street ahead of the gates. When the elephants stepped into them, they couldn’t get out. They thrashed around, knocking down their own towers and causing chaos among Demetrius’s troops. The assault collapsed into a mess. Lucas: By winter, supplies were running low for both sides. Demetrius had spent a fortune on equipment that was now sitting useless outside the walls. He heard rumors that Antigonus was facing threats elsewhere and needed him back. So, under cover of darkness, he packed up his camp and sailed away, leaving behind all his siege machines. Luna: He just gave up? Lucas: He retreated. But the Rhodians didn’t just celebrate; they solved a practical problem. They had thousands of tons of bronze and iron siege equipment left behind. Instead of letting it rust, they decided to melt it all down. The sculptor Chares of Lindos was commissioned to build a statue to honor Helios, their sun god. Lucas: This became the Colossus of Rhodes. It stood over one hundred feet tall, straddling the harbor entrance—or at least that’s what the legends say. Modern historians think it probably stood on land nearby, but the point remains: it was built from the very weapons intended to destroy them. It was a statement that freedom is stronger than force. Luna: That’s a powerful way to repurpose war material. Lucas: It was. And it wasn’t just symbolic. The Rhodians used the wealth from this project to strengthen their economy and maintain their neutrality in the ongoing wars between the other generals. They proved that small states could survive by being smarter, not just harder. Luna: I always thought the Colossus was just a statue. Lucas: It was, but it was also a monument to a specific moment in military history where technology hit a wall. You can keep building bigger machines, but if the people behind the walls are willing to adapt, you might just run out of time before you win. Lucas: Before we go deeper into the aftermath of this siege and how it shaped Rhodian politics for the next century, I want to mention something important about how this show exists. We don’t have corporate sponsors dictating our topics, and we don’t run ads interrupting your commute. That freedom comes entirely from listeners who find value in these conversations. Luna: If today felt useful to you, consider supporting us directly. Lucas: We’d love for you to join that community. You can buy me a coffee dot com slash fexingo to help keep these episodes ad-free and deeply researched. Luna: It really helps us keep making this kind of content. Lucas: Thanks for listening. Now, let’s look at what happened to Demetrius after he left Rhodes. Lucas: When Demetrius returned to mainland Greece, he found himself in a difficult position. His father Antigonus had been killed in battle, and the coalition against the Antigonids was gaining strength. Demetrius had lost a fortune and gained nothing but a reputation for stubbornness. Yet, he managed to salvage his political career. Luna: He still took Athens, right? Lucas: Yes. In fact, the Rhodians’ success inspired others. After the siege, Athens invited Demetrius to come and liberate them from another occupying power. He entered the city as a hero, earning the nickname Poliorcetes, which means Besieger. It was an ironic title, given his failure at Rhodes, but it stuck with him for the rest of his life. Lucas: The irony is thick here. He’s known for sieging cities, yet his most famous failure is what created the world’s most famous statue. It reminds us that history doesn’t always reward the strongest army. Sometimes it rewards the ones who know how to turn a loss into a legacy. Luna: The Rhodians definitely won the PR war. Lucas: They did. And they kept their independence for a long time after. It wasn’t until the Romans came along that their neutral stance finally got them absorbed into the empire. But for nearly two centuries, they were a beacon of Hellenistic culture and trade, protected by the memory of that long, muddy siege. Lucas: There’s a detail in Plutarch’s Life of Demetrius that gets overlooked. He mentions that the Rhodians sent envoys to Demetrius after he left, not to mock him, but to offer a truce and return his captured soldiers. They didn’t want to make an enemy of him permanently. It shows a level of diplomatic maturity that is often missing in these stories of glory. Luna: That’s surprisingly gracious. Lucas: It was. And it worked. Demetrius never tried to take Rhodes again. He focused his energies elsewhere, eventually becoming King of Macedon. But every time he passed the Aegean, he would look back at that island and remember the cost of trying to conquer it. The Colossus stood as a permanent reminder that some things cannot be taken by force. Luna: I wonder if Demetrius ever regretted leaving all that equipment behind. Lucas: Probably. It was incredibly expensive. But looking at the bigger picture, the Rhodians used that bronze to create something that lasted for centuries. Demetrius got a title. The Rhodians got a wonder of the world. In the long run, I’d say they got the better deal. Lucas: Next time, we’ll look at how the Hellenistic kingdoms handled succession crises, because if Demetrius’s life is any guide, family dynamics in ancient politics were just as messy as they are today. Until then, keep exploring.
