The allied Greek land forces, which Herodotus states numbered no more than 4,200 men, had chosen Thermopylae to block the advance of the much larger Persian army. Ephialtes expected to be rewarded by the Persians, but this came to nothing when they were defeated at the Battle of Salamis. According to Herodotus, he was killed for an apparently unrelated reason by Athenades (Greek: Ἀθηνάδης) of Trachis, around 470 BC, but the Spartans rewarded Athenades all the same.[5] External links[edit] Hidden categories: Articles containing Greek-language text Articles containing Ancient Greek (to 1453)-language text Edit links ./cache/en-wikipedia-org-3089.html ./txt/en-wikipedia-org-3089.txt
