The Pass of Thermopylæ was a scene strongly associated with ideas of military glory and renown. It was here that, about a hundred and fifty years before, Leonidas, a Spartan general, with only three hundred soldiers, had attempted to withstand the pressure of an immense Persian force which was at that time invading Greece. He was one of the kings of Sparta, and he had the command, not only of his three hundred Spartans, but also of all the allied forces of the Greeks that had been assembled to repel the Persian invasion. With the help of these allies he withstood the Persian forces for some time, and as the pass was so narrow between the cliffs and the sea, he was enabled to resist them successfully. At length, however, a strong detachment from the immense Persian army contrived to find their way over the mountains and around the pass, so as to establish themselves in a position from which they could come down upon the small Greek army in their rear. Leonidas, perceiving this, ordered all his allies from the other states of Greece to withdraw, leaving himself and his three hundred countrymen alone in the defile.
