Once Leonidas realizes he will be surrounded, he sends away the Greek allies to alert the cities to the south. Being too few to hold the pass, the Spartans instead attack the Persian front, where Xerxes is nearby. Leonidas is killed in the melée. Meanwhile, the Thespians, who had refused to leave, are overwhelmed (offscreen) while defending the rear. Surrounded, the surviving Spartans refuse Xerxes's demand to give up Leonidas' body. They are then all annihilated as the remaining Immortals rain down a barrage of arrowfire.
