 Militarily, the major lesson of both Plataea and Mycale (since both were fought on land) was to re-emphasise the superiority of the hoplite over the more lightly armed Persian infantry, as had first been demonstrated at Marathon.Taking on this lesson, after the Greco-Persian Wars the Persian empire started recruiting and relying on Greek mercenaries.One such mercenary expedition, the "Anabasis of the 10,000" as narrated by Xenophon, further proved to the Greeks that the Persians were militarily vulnerable even well within their own territory, and paved the way for the destruction of the Persian Empire by Alexander the Great some decades later.
