From the Greek perspective the first war was when Darius assembled a fleet in Cilicia and Samos under Datis and Artaphernes (son of the satrap Artaphernes) and sailed for Eritrea in 490 BC, first taking islands such as Naxos which it had failed to capture in 500, in addition to disembarking at Marathon where they were soundly defeated. Greek (Herodotus) and Persian sources (for instance see Dio Chrysostom XI 148) differ in terms of the significance of Marathon, great victory or minor skirmish.
