C. Julius Caesar, Gallic War

After this transaction, Caesar, having come up immediately after the battle, and imagining that the enemy, upon receiving the news of so great a defeat, would be so depressed that they would abandon their camp, which was not above eight miles distant from the scene of action, though he saw his passage obstructed by the river, yet he marched his army over and advanced. But the Bellovaci and the other states, being informed of the loss they had sustained by a few wounded men who having escaped by the shelter of the woods, had returned to them after the defeat, and learning that every thing had turned out unfavorable, that Correus was slain, and the horse and most valiant of their foot cut off, imagined that the Romans were marching against them, and calling a council in haste by sound of trumpet, unanimously cry out to send embassadors and hostages to Caesar.
