Answer:
Miltiades fought with Persians and defeated them in the famous battle of Marathon, thus proving that Greeks will not surrender to Persians.
Step-by-step explanation:
It is interesting that after Darius spread his power on the part of Europe Miltiades became his vassal. Still, when the Ionian revolt started Miltiades supported the rebels and eventually settled in Athens. As Miltiades was familiar with the Persian tactics he led the Athenian army in the battle of Marathon. In that battle Persians were heavily defeated.
