However, Darius the First(ruler of the Persian Empire) was tricky, and send half of his troops to another shore to destroy Athens.
No one was there, so the Persians ran toward Athens.
The remainders of the armies both used a wing formation.Athen's soldiers were able to win the battle.
The Persians were running toward Athens, when the Greeks came in and destroyed the rest of the Persians.
Then, they sent a messenger to tell Athens that they won.That messenger had also ran to Sparta to ask for aid in the war ,but they abstained ,due to religious reasons. That messenger died after delivering his message.His name was Pheidippides.
