Aratus (29.2-29.3)

But Aratus, returning from Cenchreae to Corinth as soon as it was dark, and posting guards along all the roads, led his Achaeans towards Cleonae, and they followed him in such good order and with such swiftness and alacrity that not only while they were on the march, but also when they had got into Cleonae, before the night was over, and had arrayed themselves for battle, Aristippus knew nothing at all of it.

Then, at daybreak, the gates were thrown open, the trumpet gave its loud signal, and dashing at a run and with shouts upon the enemy Aratus routed them at once, and kept on pursuing where he most suspected that Aristippus was in flight, the country having many diverging routes.
