History of the Peloponnesian War

but their right, where the Thebans were posted, had the advantage over the Athenians, and drove them back, and pursued them, though but gradually at first. It happened also, that Pagondas having secretly sent two squadrons of horse round the hill when his left was distressed, and these suddenly making their appearance, the victorious wing of the Athenians, thinking that another army was coming against them, was seized with a panic;

and so now on both parts of the field, owing to this supposition, and to the Thebans' pursuing them and breaking their line, the whole Athenian army took to flight.

Some hurried to Delium and the sea-coast, others towards Oropus, others to Mount Parnes, and others as they severally had hope of saving themselves.

The Boeotians, in the mean time, were pursuing them close, and putting them to the sword, especially the cavalry, both their own and the Locrian, which came to their succour just as the rout took place: but the mass of the fugitives escaped more easily than they would else have done, in consequence of night coming on before the business was over.

The next day, the troops at Oropus and those at Delium, having left a garrison in it, (for they still continued to hold it notwithstanding,) returned home by sea.

The Boeotians, after erecting a trophy, taking up their own dead, stripping those of the enemy, and leaving a guard over them, retired to Tanagra, and formed plans for assaulting Delium.
