Who were the generals of the Battle of Thermopylae?

One of the most famous battles in the Greco-Persian War was the Battle of Thermopylae. There stood the army of the Spartan king Leonidas, it blocked the passage to Thermopylae so that the Persian army could not penetrate deep into Greece, and thereby ravage its lands. The Spartan army numbered about 10 thousand soldiers, consisting of Spartans and soldiers from other policies. He was opposed by the 100 thousandth Persian army of Xerxes. During the bloody struggle, the Spartans managed to exhaust the Persians, however, at the end of the battle, the traitor told Xerxes about a secret path along which he was later able to lead his soldiers. The Spartans were forced to leave 300 soldiers to cover their retreat. They all died, like their king Leonidas.
