The Battle of Thermopylae: How 300 Spartans Held a Mountain Pass

In 480 BCE, a few thousand Greeks marched to block a mountain pass against an empire — and most of them knew they would never march back. The Battle of Thermopylae lasted three days, ended in defeat, and still changed the course of Western history.

This is the real story: why the narrow "Hot Gates" pass made Persian numbers useless, how a local Greek named Ephialtes betrayed the position through a hidden mountain path, and why King Leonidas dismissed most of his army but stayed behind with roughly 300 Spartans and several hundred Thespian volunteers.

A note on the numbers: ancient writers claimed Xerxes commanded millions. Modern historians consider that heavily exaggerated — but even conservative estimates put the Persian force at well over a hundred thousand.

This is Episode 2 of Turning Points, where we break down the moments that redirected history. The series also covers alternate history, unsolved historical mysteries, and untold stories from sports history.

Next episode: the library that burned twice — the Siege of Baghdad, 1258.
