History of the Peloponnesian War

Meanwhile the Syracusans immediately began to sail freely along the harbor, and determined to close up its mouth, so that the Athenians might not be able to steal out in future, even if they wished.

Indeed, the Syracusans no longer thought only of saving themselves, but also how to hinder the escape of the enemy; thinking, and thinking rightly, that they were now much the strongest, and that to conquer the Athenians and their allies by land and sea would win them great glory in Hellas. The rest of the Hellenes would thus immediately be either freed or released from apprehension, as the remaining forces of Athens would be henceforth unable to sustain the war that would be waged against her; while they, the Syracusans, would be regarded as the authors of this deliverance, and would be held in high admiration, not only with all men now living but also with posterity.
