Alcibiades (30.1-30.2)

While Chalcedon was being walled in from sea to sea,[*] Pharnabazus came to raise the siege, and at the same time Hippocrates, the Spartan governor, led his forces out of the city and attacked the Athenians. But Alcibiades arrayed his army so as to face both enemies at once, put Pharnabazus to shameful flight, and slew Hippocrates together with many of his vanquished men.

Then he sailed in person into the Hellespont and levied moneys there. He also captured Selymbria, where he exposed himself beyond all bounds. For there was a party in the city which offered to surrender it to him, and they had agreed with him upon the signal of a lighted torch displayed at midnight. But they were forced to give this signal before the appointed time, through fear of one of the conspirators, who suddenly changed his mind. So the torch was displayed before his army was ready; but Alcibiades took about thirty men and ran to the walls, bidding the rest of his force follow with all speed.
