 ## Context
 The battle was part of the second Persian invasion of Greece. Xerxes I (r. 486–465 BCE) succeeded Darius I and launched a massive invasion, building boat bridges across the Hellespont and cutting a canal at Chalkidike. The oracle at Delphi had warned Athens to "fly to the world's end." [^3]
 
 ## The Battle
-- Greek force of ~6,000–7,000 men held the narrow pass, including 300 Spartans, 700 Thespians, 1,000 Phokians, 1,000 Lokrians, 400 Thebans, 400 Corinthians, 2,120 Arcadians, and others [^3]
-- The 300 Spartans were chosen specifically from men who had male heirs [^3]
-- Greeks exploited the narrow terrain to negate Persian numerical advantage; Persian archers' light arrows were largely ineffective against bronze-armoured hoplites [^3]
-- Xerxes first waited four days expecting the Greeks to flee; Leonidas' reply to a demand to lay down arms was *"Molōn labe"* ("Come and take them") [^3]
-- On days one and two, even the elite Persian Immortals (10,000-strong) failed to break the Greek line [^3]
-- Betrayed by Ephialtes of Trachis, who revealed the Anopaia mountain path to outflank the Greeks [^1][^3]
-- Phokian troops guarding the Anopaia path withdrew to higher ground when the Immortals attacked, allowing the Persians to pass [^3]
-- Leonidas dismissed most allies; ~300 Spartans, ~700 Thespians, and ~400 Thebans fought to the death in a rearguard action [^1]
-- Leonidas was killed in the final stand; Xerxes ordered his head displayed on a stake [^3]
-- Archaeological excavations at Kolonos Hill (the traditional last-stand site) have uncovered spearheads, arrowheads, armor fragments, and evidence of mass cremations consistent with ancient Greek funerary practices [^4]

-- Epitaph by Simonides of Ceos: "Go tell the Spartans, stranger passing by, that here obedient to their laws we lie" [^2]
-- Bought time for the Greek fleet at Artemisium and the subsequent victory at Salamis (September 480 BCE) @t[=480 BCE]
-- Persian invasion was ultimately repulsed at Plataea (479 BCE) @t[=479 BCE]
-- Thermopylae was again the site of battle in 279 BCE (Greeks vs. Gauls), 191 BCE (Romans defeated Antiochus III), and 1941 CE (Allied forces vs. Germany) [^3]
-- Became the archetypal story of sacrifice against overwhelming odds
