The Persians invaded Ionia and the Ionians fought back. Athens sent out many ships and soldiers to help, but they still lost the battle.
We have an army!
Yeah. Still gonna lose, though.
After Athens tried to help the Ionians revolt, Darius the Great wanted revenge, so he attacked at Marathon. The Athenians had 10,000 soldiers and the Persians had 25,000. Thanks to the Athenians' better training and the phalanx, they won.
Alright, we got this!
Pheidippides ran 26 miles from Marathon to the Athenians to tell them that they had won, but died immediately after telling them
Xerxes, Darius' son, lead the Persian army to Greece in hopes to finish what his father started. They wanted to go through a mountain pass, but were stopped by Greeks. Although the Greeks were outnumbered, they used the geography towards their advantage and managed to hold off the Persians for 3 days.
This place is kinda narrow.
A traitor told the Persians about another path around the mountain pass right to Greek soldiers to surround them. Knowing that they knew a way around, the other Greek soldiers retreated back to Greece while the Spartans stood their ground. The Spartans' sacrifice was what gave the Greeks hope.
You can just go around, you know.
The Persians went through a channel to Athens to finish the battle once and for all. However, the Persian ships were too large to turn in the channel, so smaller Greek ships armed with battering rams went in and destroyed the Persian ships
