I, King Xerxes, am declaring war on Greece to avenge my father.
As the Persians sail to Greece, they loose a critical amount of soldiers in a storm.
The Persians fight the Greeks at Thermopylae for two days but suffer tremendous losses. A Greek traitor then takes the best Persian troops around the Greek army.
General Leonidas led most of the Greeks out of Thermopylae. He stayed alongside the Spartans and Thespians to fight the Persians to his death.
Themistocles pretends to feign retreat in order to lure the Persians into a narrow strait. Once their, the Persians were badly outnumbered and had to retreat to Asia after being badly beaten by the Greeks.
That winter, Xerxes returned to Persia leaving his army in Greece. However, they retreated after they were badly beaten at the battle of Plataea in 479 BCE.
