History of the Peloponnesian War

This is not to do right; but you should help us without fear of their armament, which has no terrors if we hold together, but only if we let them succeed in their endeavours to separate us; since even after attacking us by ourselves and being victorious in battle, they had to go off without effecting their purpose.

United, therefore, we have no cause to despair, but rather new encouragement to league together; especially as succors will come to us from the Peloponnesians, in military matters the undoubted superiors of the Athenians. And you need not think that your prudent policy of taking sides with neither, because allies of both, is either safe for you or fair to us.
