History of the Peloponnesian War

First, the stone-throwers, slingers, and archers of either army began skirmishing, and routed or were routed by one another, as might be expected between light troops; next, soothsayers brought forward the usual victims, and trumpeters urged on the heavy infantry to the charge;

and thus they advanced, the Syracusans to fight for their country, and each individual for his safety that day and liberty hereafter; in the enemy's army, the Athenians to make another's country theirs and to save their own from suffering by their defeat; the Argives and independent allies to help them in getting what they came for, and to earn by victory another sight of the country they had left behind; while the subject allies owed most of their ardour to the desire of self-preservation, which they could only hope for if victorious; next to which, as a secondary motive, came the chance of serving on easier terms, after helping the Athenians to a fresh conquest.
