History of the Peloponnesian War

The armies now came to close quarters, and for a long while fought without either giving ground. Meanwhile there occurred some claps of thunder with lightning and heavy rain, which did not fail to add to the fears of the party fighting for the first time, and very little acquainted with war; while to their more experienced adversaries these phenomena appeared to be produced by the time of year, and much more alarm was felt at the continued resistance of the enemy.

At last the Argives drove in the Syracusan left, and after them the Athenians routed the troops opposed to them, and the Syracusan army was thus cut in two and betook itself to flight.
