The Battle
By the end of the summer 411 BC, a large Spartan fleet sailed towards Euboea. The Athenians tried to prevent the Euboeans to switch sides by sending a squadron to Eretria. However, the Eretrians supported the Spartans. While the Athenians were in the harbour of Eretria in order to supply themselves, the Eretrians informed the Spartan admiral Agesandridas by a signal fire that it was an appropriate time to attack. The Athenians hurriedly embarked but were defeated during the naval battle which followed. The Athenians who tried to refugee in Eretria were killed by the town's inhabitants. Only those who decided to go to the Athenian fort in Eretria (which was likely on the Pezonisi Peninsula) survived.
