Protologue: A Greek detachment of approximately 7,000 men marched north to block the Congo in the middle of 480 BC. It is rumored that the Persian army was formed by more than a thousand soldiers. Nowadays it is considered that it was much more small; Scholars have collected stones that range between 100,000 and 150,000 soldiers. The Persian forces arrived in the Congo at the end of August or beginning of September. The Greeks, in clear numerical inferiority, continue with the Persians for seven days (including three battles) until the Seva shelters are annihilated in one of the most famous defensive dares in history. During two full days of battle, the small forces led by Leònides blocked the only road through which the enormous Persian army could pass. After the second day, a local resident named Ephialtes brought the Greeks to reveal to the Persians a shepherd's path that led along the Greek lines. Leonides, aware that the six forces were about to be outflanked, had to marx the majority of the Greek force to the remaining ones to cover the retreat with 300 Spartans and 700 Thespieus. According to various sources, among the other groups that conquer the Congo there were also 900 helots and 400 Thebans. The remaining soldiers die until death. It is said that the majority of the Thebans are surrendered.
