The Rogue Classicist lists this as a possible date for the Battle of Marathon. This battle in the Greco-Persian Wars is now remembered mostly for the tale about the roughly 25-mile run (now, "marathon") of Pheidippides to report to the Athenians on the battle news. Please read about the origin of the term marathon.
In the summer of 490 B.C., about 25,000 Persians, under King Darius' generals, landed on the Greek Plain of Marathon.
