Greek city-states vs Persian Empire
The Persians
They hung on defending the pass to let the rest of the Greek defenders escape to seek friendly walls before the Persian cavalry broke through. A noble sacrifice.

The battle occurred during the time of Xerxes at Themoplyae. Just Wiki Thermoplyae or Xerxes, and there you have it. The Battle of Thermopylae was fought for 3 days in the late summer of 480 BC, September perhaps. There have been several books published by historians and each has a different date for the battle; from August to September. But 480 BC is the established year.
