No , the Spartans along with a Theban contingent of infantry were overwhelmed by Persian forces at the pass of Thermopylae . But, they held up the Persian advance until the rest of the Greek city-states could coordinate their efforts to defeat the Persians. Athens' fleet defeated the Persian Navy at Salamis. Unable to receive supplies by sea, the Persians were forced to retreat overland where they were harassed by Greek guerrillas until the Spartans could exact their revenge at the Battle of Plataea.
