Pass at Thermopylae lost
Leonidas of Sparta killed
Reconstructed from historical sources
The pass at Thermopylae falls and Leonidas is killed, while the allied fleet, after three days of sea fights off Artemisium, falls back to Salamis.

THERMOPYLAE.—The pass at Thermopylae is in the king’s hands, and Leonidas, king of Sparta, is dead, killed with the men who stayed beside him on the third day of the fighting.
On the news from the pass, the allied fleet has left its station at Artemisium.
While it was still night, deserters came into the Greek camp with word that the Persians were making a circuit round the mountain, and at dawn the watchers came running down from the heights with the same news.
Or if not that, then the bound of Lacedaemon must mourn a dead king, from Heracles' lineThe priestess at Delphi
The seer Megistias, reading the sacrifices, told the Greeks that death was coming to them with the dawn.
The allies then parted. Some left for their own cities; others stayed with Leonidas. The Thespians, under their general Demophilus son of Diadromes, stayed of their own will, and Leonidas kept the Thebans back with him.
At sunrise the king poured libations, and he waited until about mid-morning before he attacked.
The Greeks fought with their spears until most of these were broken, and then with swords. Leonidas fell, and with him other Spartans of note. Two of the Persian king’s brothers fell too.
Over the body of Leonidas there was a great struggle. The Greeks dragged it clear and drove the enemy back four times. At the last they fought on with swords where they still had them, and with hands and teeth, until the enemy buried them under missiles.
When the war began, the priestess at Delphi told the Spartans that their city must be laid waste by Persian men. Her verse closed: “Or if not that, then the bound of Lacedaemon must mourn a dead king, from Heracles’ line.”
Word from the pass is that the king, told that the dead man had been king and general of the Lacedaemonians, ordered the head of Leonidas cut off and set on a stake.
