When the first Persian invasion of Greece happened, marathon then took its place. This was fought between individuals from Athens and rightly helped out by Plataea and the force from Persia which is commanded by Artaphernes and Datis. The combat was the peak of the first attempt taken up by Persia under King Darius I.
Ionian revolt was completely rumpled which then led to the Persian victory. With the great defeat of the Greek towards the Battle of Lade, Darius then began planning to greatly conquer Greece on his own which led him to send his naval task force. With how Datis and Artaphernes led the troop across the Aegean, subjugating the Cyclades is then involved. The prodigious Battle of Marathon started with how the Persian took their place on the great land of Greece.
When the force from Persia defeated the Greeks from the clash of Lade, the Athenian army was then alarmed and quickly marched and blocked the exits of the island so to stop the enemy from entering. The greatest Athenian runner named Philippides was sent to Sparta to request for some help. With such demand, the Spartan force failed his request since they can never march out of war until the moon rose fully.
With the decline of the Spartan army to help them, an unending gratitude was fully given to the Plataean troop. For approximately five days in time, these armies have surely confronted each other in stalemate. The camp of these Athenians was shielded from the grove of trees and the great delay of the Spartans settled in with how the Athenians were divided. With such division, with Miltiades as a part of it is completely keen in attacking the Persians even when he knows that the Spartans are coming.
The combat still happened. These men are still asking on why it happened even when the Spartans have not yet arrived. It is actually believed, more when Herodotus explained, that those Greeks took in the attack first but there is no distinct evidence or explanation on why they did it before the arrival of the Spartan army.
For this first theory which is quite believed to be indefinite, specifically to such part where the Greeks took advantage of such attack is because the Persian troop left the field of Marathon without any reason at all. There are actually still more variations of it and these include the most widespread one known as the reembarking of the ships of their enemies towards the sea so to take a hold of their attacks from there.
As for the second concept, it speaks simply of how the Persians attack the Athenians because they finally move their way first. Right when the Athenian troop saw the Persians advancing, they then took tactical actions and surely attacked them right in. Though both theories are not established if they are all exact yet it is noticed that the combat happened because of some kind of Persian activity which definitely triggered the war.
With these opposing troops which took up the combat, as for the Persians, though Herodotus said that there are surely a large infantry which was well packed on that day, yet for the poet Simonides, he believed that such eyed campaign force was numbered in around 200,000 which was also estimated by Cornelius Nepos. As for the Plataeans, they are all in a thousand figures while the Athenians are all in about 9,000 men.
Though Persians outnumbered the Greeks yet success was still captured by the latter. It is because of how they took in quick and exceptional tactics. More than that, they are well accustomed to their courageous hearts as well. The Battle of Marathon took place in 490 BC, during the first Persian invasion of Greece.
