Blog Number 36 - Why Greece chose Thermopylae as the battlefield in Frank Miller's '300'

In Frank Miller's '300', very little is mentioned as to why the united Greek army spearheaded (no pun intended) by King Leonidas & the 300 Spartans chose to met the Persian army at Thermopylae. Since the Persian army which numbered in the hundreds of thousands entered Northern Greece and traveled southward with the Persian navy providing support along the coastline, it was decided that Thermopylae would be the best line of defense since it was only 50 feet wide at the time in 480 B.C. and therefore could neutralize Xerxes' much larger army.

I have posted an image from 'Blog Number 24' of the Battle of Thermopylae by Stanley Meltzoff and if you would like to see others relative to the battle, please let me know.
