At the battle of Plataia in 479 BCE Herodotos says there were 5,000 Spartan hoplites (armoured infantry) with 35,000 helot light infantry (they always took seven helots per hoplite to avoid uprisings at home while the army was away). In addition, from Lakadaemonia (the Spartan territory) was an additional 5,000 hoplites and 5,000 light infantry, the whole contingent totalling 50,000.
The other Greek contingents totalled about 60,000, half hoplites, half light infantry.
It was the Battle of Thermopylae in the Second Persian War. The Greeks won. Shortly after Thermopylae the Athenian Navy defeated the Persian Navy at Salamis, and in the next year the Persian Army was defeated by a combined Greek Army at Plataea.

Darius I --- King of Persian Empire during First Persian War, 490 BC. Xerxes --- King of Persian Empire during Second Persian War, 480-479 BC. Mardonius --- Persian general in both Persian Wars. Datis and Artaphernes --- Persian generals at Battle of Marathon. Miltiades --- Athenian general at Battle of Marathon. Leonidas --- Spartan general at Battle of Thermopylae. Themistocles --- Athenian admiral at Battle of Salamis. Pausanias --- Spartan general at Battle of Plataea.
The Athenian army defeated the Persian infantry on the Plain of Marathon. Realising that the Persian cavalry was being shipped around to capture Athens in their absence, the 9,000 Athenian infantry ran back the 26 miles to the city to protect it. They ran in sandals carrying armour, shields and weapons. Today's runners get it softer.
A coalition of southern Greek city-states defeated the invading Persian army and its Greek allies.
The Persian War 499-449 BCE ended with a settlement where the Persians agreed with the anti-Persian Delian League to stay away from Greek city-states in the eastern Mediterranean littoral. The Persians had revenge when they helped the Peloponnesian League led by Sparta to defeat the empire Athens had turned the Delian League into. The Greek inter-city wars continued on unabated, and Persia re-established control over the Asian-Greek cities again as the mainland Greek cities were too busy fighting amongst themselves to worry about them.
It had 180 triremes, each with a crew of 200, making up half of the Greek fleet opposing Persia.
Socrates himself mentions that he served in the Athenian army during three campaigns : at Potidaea , Amphipolis and Delium .
Persian War - the Persian Empire versus varying coalitions of Greek city-states. Peloponnesian War - the Athenian Empire versus the Peloponnesian League led by Sparta.
For the Greeks, the Persian War was warding off Persian dominance. The Peloponnesian War was a protracted fight to terminate the Athenian Empire's attempt to dominate the other Greek city-states.
The Persian army, and the armies of the Greek city-states.
The Athenian empire was stronger at sea, the alliance led by Sparta was stronger on land.
