C. Julius Caesar, Gallic War

The Gauls having tried every expedient, as nothing had succeeded, adopted the design of fleeing from the town the next day, by the advice and order of Vercingetorix. They hoped that, by attempting it at the dead of night, they would effect it without any great loss of men, because the camp of Vercingetorix was not far distant from the town, and the extensive marsh which intervened, was likely to retard the Romans in the pursuit. And they were now preparing to execute this by night, when the matrons suddenly ran out-into the streets, and weeping cast themselves at the feet of their husbands, and requested of them, with every entreaty, that they should not abandon themselves and their common children to the enemy for punishment, because the weakness of their nature and physical powers prevented them from taking to flight. When they saw that they (as fear does not generally admit of mercy in extreme danger) persisted in their resolution, they began to shout aloud, and give intelligence of their flight to the Romans. The Gauls being intimidated by fear of this, lest the passes should be pre-occupied by the Roman cavalry, desisted from their design.
