In the year 480 B.C., the Greeks and the Persians fight one of the most famous battles in history at a place called Thermopylae. Here, the mighty Persian war machine, which has conquered most of the known world, will attempt an expansion into Europe. The only thing standing in their way will be an army led by 300 Spartans, the greatest soldiers the world has ever known. They will fight to the very last man, and in doing so will protect the cradle of democracy during its infancy, and the battle will go down in history as the greatest military stand of all time. Relying on brilliant tactics, lifelong training, and unshakable allegiance, the doomed Spartans achieved the impossible. The Battle of Thermopylae is literally a textbook case, required reading even to this day at military colleges and officer training around the world.
