History of the Peloponnesian War

It so happened also that Pagondas, seeing the distress of his left, had sent two squadrons of horse, where they could not be seen, round the hill, and their sudden appearance struck a panic into the victorious wing of the Athenians, who thought that it was another army coming against them.

At length in both parts of the field, disturbed by this panic, and with their line broken by the advancing Thebans, the whole Athenian army took to flight.

Some made for Delium and the sea, some for Oropus, others for Mount Parnes, or wherever they had hopes of safety,

pursued and cut down by the Boeotians, and in particular by the cavalry, composed partly of Boeotians and partly of Locrians, who had come up just as the rout began. Night however coming on to interrupt the pursuit, the mass of the fugitives escaped more easily than they would otherwise have done.

The next day the troops at Oropus and Delium returned home by sea, after leaving a garrison in the latter place, which they continued to hold notwithstanding the defeat.

The Boeotians set up a trophy, took up their own dead, and stripped those of the enemy, and leaving a guard over them retired to Tanagra, there to take measures for attacking Delium.

Meanwhile a herald came from the Athenians to ask for the dead, but was met and turned back by a Boeotian herald, who told him that he would effect nothing until the return of himself the Boeotian herald, and who then went on to the Athenians, and told them on the part of the Boeotians that they had done wrong in transgressing the law of the Hellenes.
