Diodorus Siculus; While these things were going on, war broke out between the Argives and the Lacedaemonians, and in a battle that took place near the city of Orneae the Lacedaemonians won, and after they had taken Orneae by siege, returned to Sparta. Chares the Athenian general sailed to the Hellespont, captured Sestus, slew its adult inhabitants, and enslaved the rest. And when Cersobleptes, son of Cotys, because of his hostility to Philip and his alliance of friendship with the Athenians, had turned over to the Athenians the cities on the Chersonese except Cardia, the assembly sent out colonists to these cities. Philip, perceiving that the people of Methonê were permitting their city to become a base of operations for his enemies, began a siege. And although for a time the people of Methonê held out, later, being overpowered, they were compelled to hand the city over to the king on the terms that the citizens should leave Methonê with a single garment each. Philip then razed the city and distributed its territory among the Macedonians. In this siege it so happened that Philip was struck in the eye by an arrow and lost the sight of that eye.
