Accordingly Hagnon took his fleet back to Athens, having lost by the plague in about forty days one thousand and fifty out of a total of four thousand hoplites; but the soldiers of the former expedition remained where they were and continued the siege of Potidaea.
After the second invasion of the Peloponnesians the Athenians underwent a change of feeling, now that their land had been ravaged a second time while the plague and the war combined lay heavily upon them.
They blamed Pericles for having persuaded them to go to war and held him responsible for the misfortunes which had befallen them, and were eager to come to an agreement with the Lacedaemonians. They even sent envoys to them, but accomplished nothing. And now, being altogether at their wits' end, they assailed Pericles.
And when he saw that they were exasperated by the present situation and were acting exactly as he had himself expected, he called a meeting of the assembly—for he was still general—wishing to reassure them, and by ridding their minds of resentment to bring them to a milder and less timorous mood. So he came forward and spoke as follows:
" I have been expecting these manifestations of your wrath against me, knowing as I do the causes of your anger, and my purpose in calling an assembly was that I might address to you certain reminders, and remonstrate if in any case you are either angry with me or are giving way to your misfortunes without reason.
