For everyone in every place, even where we are not already present, both he that thinks he will suffer wrong, and he that plots to do wrong—on account of the certain prospect that is ever present in their minds, in the one case that he will obtain succour from us in return for his allegiance, in the other that, if we shall come, he will run the risk of not escaping unscathed for his wrongdoings—are both alike under constraint, the latter to be moderate however unwilling, the former to be saved without effort of his own.
This common safety, then, which is now offered to anyone who may ask for it as well as to you, reject not; but availing yourselves of it as others do, join forces with us and instead of having always to be on your guard against the Syracusans, change your course and at length plot against them even as they have plotted against you.”
Thus Euphemus spoke. But what the Camarinaeans had felt was this: They were well disposed to the Athenians, except in so far as they thought that these would enslave Sicily; but with the Syracusans, as is usual with next-door neighbours, they were always at variance. And it was because they were more afraid of the Syracusans, as being so near, that they had in the first instance sent them the few horsemen,[*](6.67.2.) lest they might prove superior to the Athenians even without their aid; and they now resolved for the future to keep on giving to them rather than to the Athenians assistance in fact, though as moderately as possible, and for the present, in order that they might not seem to show less favour to the Athenians, especially since these had proved the stronger in the battle, to give in word the same answer to both.
Having thus determined, they made answer, that, as they were allies of both parties that were at war, it seemed to them to be consistent with their oath to aid neither at present.
So the envoys of both sides went away. The Syracusans on their side were getting ready for the war, while the Athenians who were encamped at Naxos were negotiating with the Sicels, in the effort to bring over as many of them as possible.
Now, of the Sicels that lived more toward the flat country and were subjects of the Syracusans not many[*](Or, retaining οἱ πολλοί, “most had held aloof,” ie. from the alliance with the Athenians.) had revolted; but the Sicel settlements in the interior, which even before had always been independent, with few exceptions straightway sided with the Athenians, bringing down grain for the army and in some cases money also.
