In short, we Syracusans say, that it is of no use to afford certain information, either to you or to the rest, about what you know yourselves, as well as we; but we entreat you, and at the same time protest, if we do not prevail on you, that we are plotted against by Ionians, who are always our enemies, while we are betrayed by you, Dorians by Dorians.
And if the Athenians reduce us to subjection, though it is by your decisions that they will gain the victory, it is in their own name that they will enjoy the honour; and they will receive no other prize for the victory than those men who put the victory into their hands. If, on the other hand, we are the conquerors, you will also have to submit to the punishment due to the authors of our dangers.
Consider then, and choose at once, either immediate slavery without any peril, or the chance of gaining the victory with us, and so avoiding a disgraceful submission to these men as your masters, as also of escaping our enmity, which would be of no trivial kind.
