And so the Spartans and those other Greeks who fought to the death lost the battle for Thermopylae.  The Persian army marched into central Greece, wreaking havoc and destruction.  

Although the Greeks had lost this battle, the great courage shown by the Spartans boosted the morale of other Greeks. They were not ready just yet to surrender to the Persians.

Today, a monument stands on the site of the battle to commemorate the courage of the Spartans and their commander Leonidas.
