Persia invaded peninsular Greece to incorporate it within its empire to stop the incessant wars which spilt over into the empire.
The southern Greek cities resisted, and determined to first destroy the Persian fleet to end the amphibious threat to the Greek cities, and to prevent the Persian army being resupplied by sea.
The pass at Thermopylai was blocked by a small army force from the cities, which the Persians tried to outflank by sea, running into the waiting Greek navy in the nearby strat at Artemesion.
Unfortunately for the Greeks they lost the sea battle, and as the blocking force was no longer required, it was withdrawn. The Spartan and Thespian contingent remained behind to cover its withdrawal, sacrificing themselves to let the others get away.
They did not, the Persians won; the Greeks were WAAY outnumbered.

The overall Greek strategy was to thwart the Persian advance at the narrow pass of Thermopylae using a Spartan/Thespian/Theban blocking force , while at sea the Athenian Admiral Themistocles was to prevent Persian naval forces from outflanking the Greek land contingent by making an amphibious landing behind the Spartan King Leonidas and the Greeks . Themistocles was able to defeat the Persians at the sea battle of Salamis and the Greeks were able to withstand the Persian infantry assaults only to be outflanked on the land because the traitor Ephialtes had shown the Persians a way of outflanking the Greeks by showing the Persians a way around the pass of Thermopylae .h

Holding the pass at Thermopylae was used to force a naval battle. The Greeks lost the naval battle, so it was to no avail or effect.
