Note 283 — Chapter VI · (Year of Rome 698.) (Book III. of the “Commentaries.”) WAR OF THE VENETI—VICTORY OVER THE UNELLI—SUBMISSION OF AQUITAINE—MARCH AGAINST THE MORINI AND THE MENAPII.

The fleet of the Veneti, superior to that of the Romans in number, in the magnitude of their vessels, and in their rigging and sails, must have issued from the river Auray by the Morbihan entrance to the gulf, and met Brutus to fight him, instead of waiting for him at the head of the bay, where retreat would be impossible. This follows from Cæsar’s account: ex portu profectæ, nostris adversæ constiterunt. According to the memoir by M. le Comte de Grandpré, a post-captain, inserted in the Recueil de la Société des Antiquaires de France, tom. II., 1820, the wind must have been east or north-east, for it was towards the end of the summer. It appears that these winds usually prevail at that period, and that, when they have blown during the morning, there is a dead calm towards the middle of the day: it is just what happened in this combat; the calm came, probably, towards midday. It was necessary, indeed, that the wind should be between the north and the east, to allow, on one hand the Roman fleet to leave the Loire and sail towards the Point Saint-Jacques, and, on the other, to permit the fleet of the Veneti to quit the river Auray. These latter, in this position, could, in case of defeat, take refuge in the Bay of Quiberon, or fly to the open sea, where the Romans would not have dared to follow them.

With winds blowing from below, it matters not from what point, the Romans could not have gone in search of their enemies, or the latter come to meet them. Supposing that, in one tide, the Roman fleet had arrived at the mouth of the Loire towards five o’clock in the morning; it might have been towards ten o’clock, the moment when the battle commenced, between Haedik and Sarzeau. Supposing similarly that, as early as five o’clock in the morning, the movement of the Roman fleet had been announced to the Veneti, they could, in five hours, have issued from the river Auray, defiled by the entrance of the Morbihan, rallied and advanced in order of battle to meet the Romans in the part of the sea above described.

As to the place where Cæsar encamped, it is very probable, as we have said, that it was on the heights of Saint-Gildas; for from thence he could see the dispositions of the enemy, and perceive far off the approach of his fleet. In case of check, the Roman galleys found, under his protection, a place of refuge in the Vilaine. Thus, he had his rear secured; rested upon the towns of the coast which he had taken; could recall to him, if necessary, Titurius Sabinus; and lastly, could cross the Vilaine, to place that river between him and his enemies. Placed, on the contrary, on the other side of the Bay of Quiberon, he would have been too much enclosed in an enemy’s country, and would have had none of the advantages offered by the position of Saint-Gildas.
