BATTLE OF ERETRIA The naval Battle of Eretria, between Sparta and Athens, took place in September 411 BC, off the coast of Euboea. During the spring of 411 BC, the Eretrians drove the Athenians out of Oropos with the help of the Boetians. This city was a strategic point for Athens because it allowed them to control all of Euboea. Moreover all the commercial traffic was made through the city. The Eretrians would hope that Sparta would help them to end the Athenian rule on Euboea. |
