"We have come on this embassy, men of Camarina, not because we feared that you will be dismayed by the presence of the Athenian force, but rather through fear of the words that are going to be said on their part, lest these persuade you before you hear anything from us.
For they are come to Sicily on the pretext that you hear, but with the design that we all suspect; and to me they seem to wish, not to resettle the Leontines, but rather to unsettle us. For surely it is not reasonable to suppose that, while desolating the cities in their own country, they are resettling the cities of Sicily, and that they care for the Leontines, on the score of kinship, as being Chalcidians, while holding in slavery the Chalcidians in Euboea, of whom these are colonists.
