Most people, in fact, will not take trouble in finding out the truth, but are much more inclined to accept the first story they hear. - Thucydides

The Chaonians and the other Barbarians advanced in the centre; on the right wing were the Leucadians, Anactorians, and their auxiliaries; on the left was Cnemus with the Peloponnesians and Ambraciots.The three divisions were a long way apart, and at times not even in sight of one another.

The Hellenic troops maintained order on the march and kept a look out, until at length they found a suitable place in which to encamp; the Chaonians, confident in themselves, and having a great military reputation in that part of the country, would not stop to encamp, but they and the other Barbarians rushed on at full speed, hoping to take the place by storm and appropriate to themselves the glory of the action.

The Stratians perceiving their approach in time, and thinking that, if they could overcome them before the others arrived, the Hellenic forces would not be so ready to attack them, set ambuscades near the city. When they were quite close, the troops came out of the city and from the ambuscades and fell upon them hand to hand.Whereupon the Chaonians were seized with a panic and many of them perished; the other Barbarians, seeing them give way, no longer stood their ground, but took to flight.

(Book 2 Chapter 81.3-6)

You know well as I do that when we are talking on the human plane, questions of justice only arise when there is equal power to compel: in terms of practicality the dominant exact what they can and the weak concede what they must. (Said by Athenian envoy to the Melians)

Civil war brought many hardships to the cities, such as happen and will always happen as long as human nature is the same, although they may be more or less violent or take different forms, depending on the circumstances in each case.
