Demetrius (23.1-23.2)

And now the Athenians called upon Demetrius because Cassander was besieging their city. So Demetrius sailed to their help with three hundred and thirty ships and a great number of men-at-arms, and not only drove Cassander out of Attica, but actually pursued him in his headlong flight as far as Thermopylae, and then took Heracleia, which joined him of its own accord, and six thousand Macedonians, who also came over to him.

On his return, he gave their freedom to the Greeks on this side of Thermopylae, made the Boeotians his allies, and captured Cenchreae; he also reduced Phyle and Panactum, fortresses of Attica in which Cassander had garrisons, and gave them back to the Athenians. And they, although before this they had used up and exhausted all the honours that could be bestowed upon him, nevertheless devised a way to show themselves then also the authors of new and fresh flatteries.
