After the Macedonians returned, he was sent by Antipater to Athens to "assassinate" Phocion. They disguised themselves as foreign. They were rebuffed, until the old man let Eumenes in. But their cover was blown, but no incident happened. But mobs tried to capture them, and the group dispersed. Eumenes decided to meet Phocion's friend Melanthios in Piraeus, revealed to be Eumenes's family's former slave, Charon. He fled to Pella, but midway, he met Philip busy against Athenians and Thebans. They battled on Mount Thurion. The campaign was victorious, with Alexander easily passing through the Theban and Athenian lines, casually killing then taking weapons from his enemies, then fell back.
