History of the Peloponnesian War

For in the siege of Potidaea the hoplite received a wage of two drachmas a day, one for himself and one for his attendant;

and there were at first three thousand of these, and the number was not less than this throughout the siege, besides sixteen hundred who came with Phormio, but went away before the siege was over; and the sailors on the ships all drew the same pay as the soldiers. It was in this way, then, that their money was exhausted at first, and this was the largest number of ships manned by them.
