Thermopylae

In 480 B.C. this sacred place called Thermopylae was carried out the most astonishing and unequal battle between few Greeks and a million Persians. Three hundred Spartans and seven hundred Thespians under the orders of Leonidas, king of Sparta, decided to fight against the Persians and win or die defending the freedom of their country. According to the historian Herodotus the Persian army consisted of about one million seven hundred thousand soldiers who were under the command of king Xerxes. The Persians asked the defenders to give up their arms, but Leonidas replied to them with the historic phrase "Come and get them." This phrase has been and will always be a bright example for generations to come of one's doing his duty for his country. 

A Greek traitor told the Persians of a pass through which they could cut through the mountains (left). This treacherous act caused a devastating blow to the Greek forces.
