What happened when the Persians invaded Greece?

Answer 1

They were initially successful, captiring mainland Greece down to and including Athens, and bringing most of the occupied cities under their side and adding their armies to their own. However their naval defeat at Salamis exposed their supply line, and with the winter coming on they had to send half their army home and withdraw to northern Greece to find sustenance.

In the spring, with their cities no longer threatened by amphibious attack by the Persian fleet, the southern Greeks were able to send out their armies to concentrate against the depleted Persian army and its central Greek allies. They won, and the remaining Persians all went home.
