C. Julius Caesar, Gallic War

Induced by all these things, the enemy lead over their forces and draw up their line in a disadvantageous position; and as our men also had been led down from the ramparts, they approach nearer, and throw their weapons into the fortification from all sides, and sending heralds round, order it to be proclaimed that, if "any, either Gaul or Roman, was willing to go over to them before the third hour, it was permitted; after that time there would not be permission;" and so much did they disregard our men, that the gates having been blocked up with single rows of turf as a mere appearance, because they did not seem able to burst in that way, some began to pull down the rampart with their hands, others to fill up the trenches. Then Caesar, making a sally from all the gates, and sending out the cavalry, soon puts the enemy to flight, so that no one at all stood his ground with the intention of fighting; and he slew a great number of them, and deprived all of their arms.
