Plutarch, Aratus
Bernadotte Perrin, Ed.

31. In the Aetolian war also Aratus won a good repute. For when the Achaeans were bent on an engagement with the Aetolians in front of Megara, and Agis the king of the Lacedaemonians was come up with an army and joined in urging the Achaeans on to battle, Aratus opposed this counsel, and in spite of much vilification and much scoffing abuse for weakness and cowardice would not abandon, because of any seeming disgrace, which he judged to be for the general advantage, but allowed the enemy to cross the Geraneian range without a battle and pass on into Peloponnesus. [2] When, however, after thus passing on, they suddenly seized Pellene, he was no longer the same man, nor would he wait at all in order that his forces might assemble and come together from all quarters, but at once set out with those he had against the enemy, whom the disorder and wantonness attendant upon their success had wholly weakened. [3] For as soon as they had entered the city, the common soldiers had scattered themselves among the houses, jostling and fighting with one another over the booty, while the leaders and captains were going about and seizing the wives and daughters of the Pellenians, on whose heads they put their own helmets, that no one else might seize them, but that the helmet might show to whom each woman belonged. But while they were in this situation and thus engaged, word was suddenly brought them that Aratus had attacked. Dismay fell upon them, as was natural amid such disorder, and before all had learned of the danger the foremost of them, engaging with the Achaeans at the gates and in the suburbs, were already conquered and in full flight, and being driven in headlong rout, they filled with dismay those who were collecting together and coming to their aid.
