him fled into the city; at the same instant Pharnabazus, unable to
effect a junction with the Lacedaemonian leader, owing to the
circumscribed nature of the ground and the close proximity of the
river to the enemy's lines, retired to the Heracleium,[2] belonging to
the Chalcedonians, where his camp lay. After this success Alcibiades
set off to the Hellespont and the Chersonese to raise money, and the
remaining generals came to terms with Pharnabazus in respect of
Chalcedon; according to these, the Persian satrap agreed to pay the
Athenians twenty talents[3] in behalf of the town, and to grant their
ambassadors a safe conduct up country to the king. It was further
stipulated by mutual consent and under oaths provided, that the
Chalcedonians should continue the payment of their customary tribute
to Athens, being also bound to discharge all outstanding debts. The
Athenians, on their side, were bound to desist from all hostilities
until the return of their ambassadors from the king. These oaths were
not witnessed by Alcibiades, who was now in the neighbourhood of
Selybria. Having taken that place, he presently appeared before the
walls of Byzantium at the head of the men of Chersonese, who came out
with their whole force; he was aided further by troops from Thrace and
more than three hundred horse. Accordingly Pharnabazus, insisting that
he too must take the oath, decided to remain in Chalcedon, and to
await his arrival from Byzantium. Alcibiades came, but was not
prepared to bind himself by any oaths, unless Pharnabazus would, on
his side, take oaths to himself. After this, oaths were exchanged
between them by proxy. Alcibiades took them at Chrysopolis in the
presence of two representatives sent by Pharnabazus--namely,
Mitrobates and Arnapes. Pharnabazus took them at Chalcedon in the
presence of Euryptolemus and Diotimus, who represented Alcibiades.
Both parties bound themselves not only by the general oath, but also
interchanged personal pledges of good faith.
