In Sparta, his fellow king Leotychidas is fighting a losing battle with the Ephors over the religious harvest festival of Carnea that is due to take place, with members of the council arguing that the army should wait until after the festival is over before it marches, while Leotychidas fears that by that time the Persians may have conquered Greece. Leonidas decides to march north immediately with his personal bodyguard of 300 men, who are exempt from the decisions of the Ephors and the Gerousia. They are subsequently reinforced by about 700 volunteer Thespians led by Demophilus and few other Greek allies.
