Transcript
- Lucas: Welcome back to the show. If you've been stepping into history with us episode by episode through the Achaemenid Empire, you know we've talked about battles, roads, and religious tolerance. But today I want to focus on something that truly shows the Persian military genius: siege warfare. Luna: I've always been curious about that. We hear so much about Greek hoplites and Macedonian phalanxes, but the Persians took cities on a massive scale. Lucas: Exactly. The Achaemenids didn't just rely on cavalry or archers. They developed a sophisticated siege doctrine that combined engineering, logistics, and psychological operations. Think of the sheer number of fortified cities they captured: Babylon, Sardis, Memphis, Miletus, Bactra—and that's just the ones we have records for. Lucas: Herodotus and the Babylonian Chronicle give us glimpses, but we also have archaeological evidence from sites like Persepolis and the reliefs at Behistun. The Persians were masters of adapting what they learned from conquered peoples. Luna: So they didn't have one single 'Persian way' of siege? They borrowed tactics? Lucas: Right. They were incredibly pragmatic. When Cyrus the Great took Babylon in 539 BCE, he famously diverted the Euphrates River to march his troops into the city under the walls. That was a clever use of engineering and surprise—the Babylonians were celebrating a festival and didn't expect an attack from the riverbed. Lucas: But earlier, when Cyrus conquered Sardis, the capital of Lydia, he used a different trick. According to Herodotus, he placed dromedaries—camel riders—in front of his army, because the Lydian horses were terrified of the smell of camels. That broke the Lydian cavalry charge, and then the city fell quickly. Luna: Wait, camels against horses? That's brilliant—but also a bit absurd. Lucas: It worked. And it shows the Persian willingness to think outside the box. Now, by the time of Darius the Great, Persian siege engineering had become more standardized. They built massive earth ramps, used battering rams covered in wet hides to prevent burning, and employed sappers to tunnel under walls. Lucas: One of the most detailed accounts comes from the Ionian Revolt around 499 BCE. The city of Miletus was besieged by the Persians after a long campaign. They built a siege mound and used battering rams against the walls. The defenders, led by the Greek historian Hecataeus? Actually, it was Aristagoras, but he fled. Anyway, the Persians eventually breached the walls and destroyed the city. Luna: That was a turning point. The fall of Miletus essentially ended the Ionian Revolt. Lucas: Absolutely. And it set the stage for the Persian invasions of Greece. But the Persians also used siege towers—called 'helepoleis' in Greek, though that term is later. They were multi-story wooden structures on wheels, filled with archers and lighter infantry, pushed up against the walls. The defenders would try to set them on fire, but the Persians covered them with untreated hides that were hard to burn. Lucas: Another key component was the sparabara—the shield-bearers. These were infantrymen armed with a large wicker shield and a short spear. In sieges, they would form a protective screen for archers and engineers, advancing under a hail of arrows from the walls. Luna: So they were like mobile cover for the siege works. Lucas: Exactly. And the Persian logistics were astonishing. They could move siege trains across hundreds of miles using the Royal Road and the network of supply depots. For the siege of Bactria, which we covered in episode 101, they transported heavy equipment through mountain passes. Lucas: But perhaps the most famous siege from the Persian perspective—though it happened after the empire fell—is Alexander the Great's siege of Tyre in 332 BCE. That was a Persian city, defended by Phoenicians loyal to Darius III. Alexander built a causeway half a mile long to reach the island city, using rubble from the mainland. It took seven months. Luna: And the Persians had actually used Tyre as a naval base. So losing it was a huge blow. Lucas: It was. But the point is, the Persians themselves had taken Tyre earlier, though under different circumstances. When Cambyses II conquered Egypt, the Phoenician cities submitted voluntarily. But if they hadn't, the Persians had the capability to reduce them. Lucas: There's also the siege of Sardis again, under Cyrus, which we've mentioned. But the Persians also had a clever psychological tool: they would offer generous terms to cities that surrendered, and only destroy those that resisted. This encouraged many cities to open their gates without a fight. Luna: That reminds me of the Cyrus Cylinder—the propaganda about freeing Babylonians from Nabonidus. Lucas: Exactly. It was part of a deliberate policy. So when we think of Persian siege warfare, we shouldn't just imagine brute force. It was a combination of engineering, logistics, psychology, and adaptation. They learned from the Assyrians, the Medes, the Greeks, and others, and made it their own. Luna: It's a shame we don't have more Persian sources—the Greek accounts are biased. Lucas: True. But we do have the Persepolis Fortification Tablets and some Babylonian records. They show that siege warfare was a major concern for the empire. Satraps were responsible for maintaining local fortifications and siege equipment. Lucas: So after all this, I think it's fair to say that the Achaemenid Persians were among the most effective besiegers of the ancient world, long before Alexander came along. Luna: If today was actually useful to you, the way these shows stay ad-free is listener support. You can buy me a coffee at buy me a coffee dot com slash fexingo. Lucas: Absolutely. Every little bit helps us keep diving into these topics without corporate interruptions. And speaking of diving deeper—next time, we'll look at how the Persians managed their vast postal system, which was just as impressive as their siege tactics. Luna: Can't wait for that. Until then, thanks for listening.
