History of the Peloponnesian War

But if Syracuse falls, all Sicily falls also, and Italy immediately afterwards; and the danger which I just now spoke of from that quarter will before long be upon you.

None need therefore fancy that Sicily only is in question; Peloponnese will be so also, unless you speedily do as I tell you, and send on board ship to Syracuse troops that shall be able to row their ships themselves, and serve as heavy infantry the moment that they land; and what I consider even more important than the troops, a Spartan as commanding officer to discipline the forces already on foot and to compel recusants to serve. The friends that you have already will thus become more confident, and the waverers will be encouraged to join you.

Meanwhile you must carry on the war here more openly, that the Syracusans seeing that you do not forget them, may put heart into their resistance, and that the Athenians may be less able to reinforce their armament.

You must fortify Decelea in Attica, the blow of which the Athenians are always most afraid and the only one that they think they have not experienced in the present war; the surest method of harming an enemy being to find out what he most fears, and to choose this means of attacking him, since every one naturally knows best his own weak points and fears accordingly.

The fortification in question, while it benefits you, will create difficulties for your adversaries, of which I shall pass over many, and shall only mention the chief. Whatever property there is in the country will most of it become yours, either by capture or surrender; and the Athenians will at once be deprived of their revenues from the silver mines at Laurium, of their present gains from their land and from the law courts, and above all of the revenue from their allies, which will be paid less regularly, as they lose their awe of Athens, and see you addressing yourselves with vigour to the war.
