Note 247 — Chapter V · WAR AGAINST THE BELGÆ. (Year of Rome 697.) (Book II. of the “Commentaries.”)

The following localities have been suggested for Bibrax: Bièvre, Bruyères, Neufchâtel, Beaurieux, and the mountain called Vieux-Laon. Now that the camp of Cæsar has been discovered on the hill of Mauchamp, there is only room to hesitate between Beaurieux and Vieux-Laon, as they are the only localities among those just mentioned which, as the text requires, are eight miles distant from the Roman camp. But Beaurieux will not suit, for the reason that even if the Aisne had passed, at the time of the Gallic war, at the foot of the heights on which the town is situated, we cannot understand how the re-enforcements sent by Cæsar could have crossed the river and penetrated into the place, which the Belgian army must certainly have invested on all sides. This fact is, on the contrary, easily understood when we apply it to the mountain of Vieux-Laon, which presents towards the south impregnable escarpments. The Belgæ would have surrounded it on all parts except on the south, and it was no doubt by that side that, during the night, Cæsar’s re-enforcements would enter the town.
