During the Corinthian War, Sestos was occupied by Athenian forces led by Conon in 393, and the city came under the control of Ariobarzanes, Satrap of Phrygia. In 365, an attack on Sestos by Cotys I, King of Thrace, was repelled with the aid of Timotheus, for which Athens was awarded with Sestos and Krithotai in the same year. A cleruchy was established at Sestos in 364, but the city was conquered by Cotys I after a surprise attack in 360, and a Thracian garrison was established. The Athenian general Chares seized Sestos in 353 and carried out "andrapodismos" whereby the male population was killed and women and children were enslaved; the city was repopulated by Athenian cleruchs.
