History of the Peloponnesian War

This we should scarcely be able to do, even if we had plenty of ships to spare, and were freed from our present necessity of exhausting all our strength upon the blockade. For it is already difficult to carry in supplies past Syracuse; and were we to relax our vigilance in the slightest degree it would become impossible.

The losses which our crews have suffered and still continue to suffer arise from the following causes. Expeditions for fuel and for forage, and the distance from which water has to be fetched, cause our sailors to be cut off by the Syracusan cavalry; the loss of our previous superiority emboldens our slaves to desert; our foreign seamen are impressed by the unexpected appearance of a navy against us, and the strength of the enemy's resistance; such of them as were pressed into the service take the first opportunity of departing to their respective cities; such as were originally seduced by the temptation of high pay, and expected little fighting and large gains, leave us either by desertion to the enemy or by availing themselves of one or other of the various facilities of escape which the magnitude of Sicily affords them. Some even engage in trade themselves and prevail upon the captains to take Hyccaric slaves on board in their place; thus they have ruined the efficiency of our navy.

Now I need not remind you that the time during which a crew is in its prime is short, and that the number of sailors who can start a ship on her way and keep the rowing in time is small.

But by far my greatest trouble is, that holding the post which I do, I am prevented by the natural indocility of the Athenian seaman from putting a stop to these evils; and that meanwhile we have no source from which to recruit our crews, which the enemy can do from many quarters, but are compelled to depend both for supplying the crews in service and for making good our losses upon the men whom we brought with us. For our present confederates, Naxos and Catana, are incapable of supplying us.

There is only one thing more wanting to our opponents, I mean the defection of our Italian markets. If they were to see you neglect to relieve us from our present condition, and were to go over to the enemy, famine would compel us to evacuate, and Syracuse would finish the war without a blow.
