In 490 BC, Darius the Great, having suppressed the Ionian cities, sent a Persian fleet to punish the Greeks. (Historians are uncertain about their number of men; accounts vary from 18,000 to 100,000.) They landed in Attica intending to take Athens, but were defeated at the Battle of Marathon by a Greek army of 9,000 Athenian hoplites and 1,000 Plataeans led by the Athenian general Miltiades. The Persian fleet continued to Athens but, seeing it garrisoned, decided not to attempt an assault.
