Histories

As for the Athenians and those whose place was nearest them, that is, for about half of the line, their way lay over the beach and level ground; for the Lacedaemonians and those that were next to them, their way lay through a ravine and among hills. While the Lacedaemonians were making a circuit, those others on the other wing were already fighting.

As long as the Persians' shields stood upright, they defended themselves and held their own in the battle, but when the Athenians and their neighbors in the line passed the word and went more zealously to work, that they and not the Lacedaemonians might win the victory, immediately the face of the fight changed.
