fleet occupied the first place among all the Celtic cantons in navigation and commerce - and generally the coast- districts between the Loire and Seine, to submit to the Romans and give them hostages. But they soon repented.
When in the following winter (697-698) Roman officers came to these legions to levy requisitions of grain there, they were detained by the Veneti as counter-hostages. The example thus set was quickly followed not only by the Aremorican cantons, but also by the maritime cantons of the Belgae that still remained free; where, as in some cantons of Normandy, the common council refused to join the insurrection, the multitude put them to death and attached itself with redoubled zeal to the national cause.
The whole coast from the mouth of the Loire to that of the Rhine rose against Rome; the most resolute patriots from all the Celtic cantons hastened thither to co-operate in the great work of liberation; they already calculated on the rising of the whole Belgic confederacy, on aid from Britain, on the arrival of Germans from beyond the Rhine. Caesar sent Labienus with all the cavalry to the Rhine, with a view to hold in check the agitation in the Belgic province, and in case of need to prevent the Germans from crossing the river; another of his lieutenants, Quintus Titurius Sabinus, went with three legions to Normandy, where the main body of the insurgents assembled. But the powerful and intelligent Veneti were the true centre of the insurrection; the chief attack by land and sea was directed against them. Caesar's lieutenant, Decimus Brutus, brought up the fleet formed partly of the ships of the subject Celtic cantons, partly of a number of Roman galleys hastily built on the Loire and manned with rowers from the Narbonese province; Caesar himself advanced with the flower of his infantry into the territory of the Veneti.
But these were prepared beforehand, and had with equal skill and resolution availed themselves of the favourable circumstances which the nature of the ground in Brittany and the possession of a considerable naval power presented. The country was much intersected and poorly furnished with grain, the towns were situated for the most part on cliffs and tongues of land, and were accessible from the mainland only by shallows which it was difficult to cross; the provision of supplies and the conducting of sieges were equally difficult for the army attacking by land, while the Celts by means of their vessels could furnish the towns easily with everything needful, and in the event of the worst could accomplish their evacuation. The legions expended their time and strength in the sieges of the Venetian townships, only to see the substantial fruits of victory ultimately carried off in the vessels of the enemy.
Accordingly when the Roman fleet, long detained by storms at the mouth of the Loire, arrived at length on the coast of Brittany, it was left to decide the struggle by a naval battle. The Celts, conscious of their superiority on this element, brought forth their fleet against that of the Romans commanded by Brutus. Not only did it number 220 sail, far more than the Romans had been able to bring up, but their high-decked strong sailing-vessels with flat bottoms were also far better adapted for the high-running waves of the Atlantic Ocean than the low, lightly- built oared galleys of the Romans with their sharp keels. Neither the missiles nor the boarding-bridges of the Romans could reach the high deck of the enemy's vessels, and the iron beaks recoiled powerless from the strong oaken planks. But the Roman mariners cut the ropes, by which the yards were fastened to the masts, by means of sickles fastened to long poles; the yards and sails fell down, and, as they did not know how to repair the damage speedily, the ship was thus rendered a wreck just as it is at the present day by the falling of the masts, and the Roman boats easily succeeded by a joint attack in mastering the maimed vessel of the enemy. When the Gauls perceived this manoeuvre, they attempted to move from the coast on which they had taken up the combat with the Romans, and to gain the high seas, whither the Roman galleys could not follow them; but unhappily for them there suddenly set in a dead calm, and the immense fleet, towards the equipment of which the maritime cantons had applied all their energies, was almost wholly destroyed by the Romans. Thus was this naval battle - so far as historical knowledge reaches, the earliest fought on the Atlantic Ocean - just like the engagement at Mylae two hundred years before[39], notwithstanding the most unfavourable circumstances, decided in favour of the Romans by a lucky invention suggested by necessity. The consequence of the victory achieved by Brutus was the surrender of the Veneti and of all Brittany. More with a view to impress the Celtic nation, after so manifold evidences of clemency towards the vanquished, by an example of fearful severity now against those whose resistance had been obstinate, than with the view of punishing the breach of treaty and the arrest of the Roman officers, Caesar caused the whole common council to be executed and the people of the Venetian canton to the last man to be sold into slavery.
By this dreadful fate, as well as by their intelligence and their patriotism, the Veneti have more than any other Celtic clan acquired a title to the sympathy of posterity.
Sabinus meanwhile opposed to the levy of the coast-states assembled on the Channel the same tactics by which Caesar had in the previous year conquered the Belgic general levy on the Aisne; he stood on the defensive till impatience and want invaded the ranks of the enemy, and then managed by deceiving them as to the temper and strength of his troops, and above all by means of their own impatience, to allure them to an imprudent assault upon the Roman camp, in which they were defeated; whereupon the militia dispersed and the country as far as the Seine submitted.
The Morini and Menapii alone persevered in withholding their recognition of the Roman supremacy. To compel them to this, Caesar appeared on their borders; but, rendered wiser by the experiences of their countrymen, they avoided accepting battle on the borders of their land, and retired into the forests which then stretched almost without interruption from the Ardennes towards the German Ocean. The Romans attempted to make a road through the forest with the axe, ranging the felled trees on each side as a barricade against the enemy's attacks; but even Caesar, daring as he was, found it advisable after some days of most laborious marching, especially as it was verging towards winter, to order a retreat, although but a small portion of the Morini had submitted and the powerful Menapii had not been reached at all. In the following year (699) while Caesar himself was employed in Britain the greater part of the army was sent afresh against these tribes; but this expedition also remained in the main unsuccessful. Nevertheless the result of the last campaigns was the almost complete reduction of Gaul under the dominion of the Romans. While central Gaul had submitted to it without resistance, during the campaign of 697 the Belgic, and during that of the following year the maritime, cantons had been compelled by force of arms to acknowledge the Roman rule.
The lofty hopes, with which the Celtic patriots had begun the last campaign, had nowhere been fulfilled. Neither Germans nor Britons had come to their aid; and in Belgica the presence of Labienus had sufficed to prevent the renewal of the conflicts of the previous year.
While Caesar was thus forming the Roman domain in the west by force of arms into a compact whole, he did not neglect to open up for the newly-conquered country - which was destined in fact to fill up the wide gap in that domain between Italy and Spain-communications both with the Italian home and with the Spanish provinces. The communication between Gaul and Italy had certainly been materially facilitated by the military road laid out by Pompeius in 677 over Mont Genevre[40]; but since the whole of Gaul had been subdued by the Romans, there was need of a route crossing the ridge of the Alps from the valley of the Po, not in a westerly but in a northerly direction, and furnishing a shorter communication between Italy and central Gaul. The way which leads over the Great St. Bernard into the Valais and along the lake of Geneva had long served the merchant for this purpose; to get this road into his power, Caesar as early as the autumn of 697 caused Octodurum (Martigny) to be occupied by Servius Galba, and the inhabitants of the Valais to be reduced to subjection - a result which was, of course, merely postponed, not prevented, by the brave resistance of these mountain-peoples.
