 Athens sent out new settlers to the cleruchs on the Chersonsese under the command of Diopeithes, who proceeded to ravage the territory of Cardia, an ally of Philip.Philip therefore wrote to the Athenians to demand that they desist, but in his speech 'On the Chersonese', Demosthenes persuaded the Athenians that since Athens was effectively at war with Philip anyway, there was no need to do what Philip asked; Diopeithes therefore continued to cause trouble in Thrace.Then, in the Third Philippic of approximately May 341 BC, Demosthenes accused Philip of breaking the peace by intervening in the affairs of Euboea.
