Caesar bellum Gallicum 1.53-54

So the battle swung back in our favour, and all the enemy turned tail and did not stop running until they reached the Rhine, nearly five miles away from the field of battle. There a very few trusted in their own strength and aimed to swim across, or found boats and thus ensured their own safety. Ariovistus was of their number. He found a small boat moored to the bank, and escaped in it. Our men pursued all the rest of the enemy with the cavalry and killed them.

Ariovistus had two wives, one a woman of the Suebi (he had brought her with him from Germany) and the other one from Noricum, the sister of King Voccio, who had sent her to be married to him in Gaul. Both wives perished in the flight. One of his daughters also died, but the other was captured. Gaius Valerius Procillus, bound in triple chains, was being dragged by his guards in the flight when he met with Caesar himself, pursuing the enemy with the cavalry. It brought Caesar as much pleasure as the victory itself to see this most worthy provincial, his own companion and close friend, snatched from the hand of the enemy and restored to him: nor had Procillus suffered any terrible fate such as would lessen in any degree Caesar's great pleasure and joy. Procillus recounted how in his presence lots had three times been cast to decide whether he should be burned to death or kept back for a later occasion-but thanks to the lots, he was uninjured. So also Marcus Mettius was found and taken back to Caesar.

(54) News of the battle spread across the Rhine. The Suebi who had come to the banks of the river began to move back home; and when the people who dwell near the Rhine realized their panic, they pursued and killed a large number of them.

Caesar had conducted two major campaigns in a single season, and now, a little later than the time of year required, he led his army to the land of the Sequani to winter quarters. There he put Labienus in, charge. He himself set out for Nearer Gaul, to hold assizes.
