History of the Peloponnesian War

For a hundred kept guard round Attica, Euboea, and Salamis, while another hundred were cruising about the Peloponnese, besides those at Potidaea and in other places; so that altogether there were two hundred and fifty [in service] in the course of that one summer. And it was this, in conjunction with Potidaea, that most exhausted their revenues.

For at Potidaea the number of heavy-armed that kept guard at two drachmas a day,

(for each man received one for himself and another for his servant,) was at first three thousand; and not fewer than these remained there to the end of the siege, besides one thousand six hundred with Phormio, who went away before it was concluded while all the ships, too, received the same pay. In this way then was their money heedlessly lavished at first; and such was the largest number of ships manned by them.

At the same time that the Lacedaemonians were in the neighbourhood of the isthmus, the Mytilenaeans marched by land, both themselves and their auxiliaries, against Methymna, in hope of its being betrayed to them. After assaulting the city, when they did not succeed as they had expected to do, they withdrew to Antissa, Pyrrha, and Eresus, and having rendered the condition of those towns more secure. and strengthened the fortifications, they returned home.
