How Ephialtes Sacrificed Everything for a Single, Decisive Historical Betrayal In the annals of ancient history, few acts carry the weight, ruin, and enigma of Ephialtes’ betrayal at the Thermopylae pass. Known as the man whose tortuous advice turned the tide of one of antiquity’s most legendary standings, Ephialtes’ name is etched not in grandeur or honor, but in calculated self-sacrifice for a moment of ultimate personal gain — and addiction to power. ### The Betrayal That Changed the Course of War Ephialtes of Trachis emerged not from royal blood or noble lineage, but from a minor local ruler in Phocis. When the Persian army under Xerxes moved south in 480 BCE, Ephialtes seized a dangerous opportunity: offering crucial intelligence about a hidden mountain path — the Anopaia trail — that skirted the Persian front lines. This path allowed the Persians to outflank the united Greek hoplites entrenched at Thermopylae. His act was a literal turning point — enabling the Persian flanking maneuver that ultimately led to the fall of King Leonidas and his 300 Spartans.
