History of the Peloponnesian War

For paying much money to strangers and laying out much more on forts [without and about the city], having also had a great navy a year already in pay, they must needs want money at last, and all these things fail them. For they have spent already two thousand talents, and are much in debt besides. And whensoever they shall give over this course and make pay no longer, their strength is gone, as being auxiliary and not constrained to follow the war as the Athenians are.

Therefore it was fit, he said, to stay close to the city and not to go away as if they were too weak in money, wherein they were much superior.

Nicias, when he spake this, assured them of it, as knowing the state of Syracuse precisely and their want of money, and that there were some that desired to betray the city to the Athenians and sent him word not to go. Withal he had now confidence in the fleet, which, as being before overcome, he had not.

As for lying where they did, Demosthenes would by no means hear of it. But if the army might not be carried away without order from the Athenians but must needs stay in Sicily, then, he said, they might go to Thapsus or Catana, from whence by their landmen they might invade and turn much of the country to them and wasting the fields of the enemies, weaken the Syracusians; and be to fight with their galleys in the main sea, and not in a narrow (which is the advantage of the enemy), but in a wide place, where the benefit of skill should be theirs, and where they should not be forced, in charging and retiring, to come up and fall off in narrow and circumscribed limits.
