History of the Peloponnesian War

For men are always exasperated at suffering injuries to which they are not accustomed, and on seeing them inflicted before their very eyes; and where least inclined for reflection, rush with the greatest heat to action.

The Athenians are the very people of all others to do this, as they aspire to rule the rest of the world, and are more in the habit of invading and ravaging their neighbors' territory, than of seeing their own treated in the like fashion.

Considering, therefore, the power of the state against which we are marching, and the greatness of the reputation which, according to the event, we shall win or lose for our ancestors and ourselves, remember as you follow where you may be led to regard discipline and vigilance as of the first importance, and to obey with alacrity the orders transmitted to you; as nothing contributes so much to the credit and safety of an army as the union of large bodies by a single discipline.’

With this brief speech dismissing the assembly, Archidamus first sent off Melesippus, son of Diacritus, a Spartan, to Athens, in case she should be more inclined to submit on seeing the Peloponnesians actually on the march.

But the Athenians did not admit him into the city or to their assembly; Pericles having already carried a motion against admitting either herald or embassy from the Lacedaemonians after they had once marched out. The herald was accordingly sent away without an audience, and ordered to be beyond the frontier that same day; in future, if those who sent him had a proposition to make they must retire to their own territory before they dispatched embassies to Athens. An escort was sent with Melesippus to prevent his holding communication with any one.
