History of the Peloponnesian War

"For I say that going thither you leave many enemies here behind you, and more you endeavour to draw hither.

You perhaps think that the league will be firm that you have made with the Lacedaemonians; which, though as long as you stir not, may continue a league in name (for so some have made it of their own side ), yet if any considerable forces of ours chance to miscarry, our enemies will soon renew the war, as having made the peace constrained by calamities, and upon terms of more dishonour and necessity than ourselves; besides, in the league itself we have many things controverted. And some there be that refuse utterly to accept it, and they none of the weakest;

whereof some are now in open war against us, and others, because the Lacedaemonians stir not, maintain only a truce with us from ten to ten days, and so are contented yet to hold their hands.

But, peradventure, when they shall hear that our power is distracted, which is the thing we now hasten to do, they will be glad to join in the war with the Sicilians against us, the confederacy of whom they would heretofore have valued above many other.

It behoveth us therefore to consider of these things and not to run into new dangers when the state of our own city hangeth unsettled, nor seek a new dominion before we assure that which we already have. For the Chalcideans of Thrace, after so many years' revolt, are yet unreduced; and from others in divers parts of the continent we have but doubtful obedience. But the Egestaeans, being forsooth our confederates and wronged, they in all haste must be aided; though to right us on those by whom we have a long time ourselves been wronged, that we defer.
