References in classic literature ?
I propose that we retire to a discreet distance from this impregnable position, and there hold a convocation, or council, to deliberate on what manner we may sit down regularly before the place; or, perhaps, by postponing the siege to another season, gain the aid of auxiliaries from the inhabited countries, and thus secure the dignity of the laws from any danger of a repulse.
