1, the marathon. Persia invaded Greece for the first time. Athens sent Miti Ades 1 10,000 infantry to the Marathon Plain where the Persian army landed, and finally defeated the Persian army with fewer troops.

2. Hot spring pass activity. Spartan King Leonidas was responsible for defending the first line of defense of Greece-Wenquanguan with 300 soldiers from his own country and 7,000 people from other city-states in the Peloponnesian Peninsula, and stopped the Persian army from advancing two days ago. However, in the end, the Spartan army was wiped out because of the disparity in numbers.

3. Battle of Salami Bay. In September 480 BC, more than 300 warships of Athens assembled in Salami Bay, and sent people to pretend to be deserters, and lied to the Persian king that the Athenian fleet was fighting and wanted to send troops immediately. As a result, they successfully lured the Persian king to order more than 600 giant warships of the whole army to sail into the bay. The Greek fleet hid behind Mount Egareos, formed a two-line battle formation and bravely launched an attack.

Persian navy suffered heavy losses in the battle of Salamis, and Xerxes I, who was a personal expedition to Greece, was afraid that the posterior route would be cut off and fled back to China. Its troops retreated to northern Greece.
