II.--Taming the Rebellious Belgæ
While Cæsar was in winter quarters in Hither Gaul frequent reports were brought to him that all the Belgæ were entering into a confederacy against the Roman people, because they feared that, after all Celtic Gaul was subdued, our army would be led against them. Cæsar, alarmed, levied two new legions in Hither Gaul, and proceeded to the territory of the Belgæ. As he arrived there unexpectedly, and sooner than anyone anticipated, the Remi, who are the nearest of the Belgæ to Celtic Gaul, sent messages of submission and gave Cæsar full information about the other Belgæ.
Cæsar next learned that the Nervii, a savage and very brave people, whose territories bordered those just conquered, had upbraided the rest of the Belgæ who had surrendered themselves to the Roman people, and had declared that they themselves would neither send ambassadors nor accept any condition of peace. He was informed concerning them that they allowed no access of any merchants, and that they suffered no wine and other things tending to luxury to be imported, because they thought that by their use the mind is enervated and the courage impaired.
After he had made three days' march into their territory, Cæsar discovered that all the Nervii had stationed themselves on the other side of the River Sambre, not more than ten miles from his camp, and that they had persuaded the Atrebates and the Veromandui to join with them, and that likewise the Aduatuci were expected by them, and were on the march. The Roman army proceeded to encamp in front of the river, on a site sloping towards it. Here they were fiercely attacked by the Nervii, the assault being so sudden that Cæsar had to do all things at one time. The standard as the sign to run to arms had to be displayed, the soldiers were to be called from the works on the rampart, the order of battle was to be formed, and a great part of these arrangements was prevented by the shortness of time and the sudden charge of the enemy.
Time was lacking even for putting on helmets and uncovering shields. In such an unfavorable state of affairs, various events of fortune followed. The soldiers of the ninth and tenth legions speedily drove back the Atrebates, who were breathless with running and fatigue. Many of them were slain. In like manner the Veromandui were routed by the eighth and eleventh legions; but as part of the camp was very exposed, the Nervii hastened in a very close body, under Boduagnatus, their leader, to rush against that quarter. Our horsemen and light-armed infantry were by the first assault routed, and the enemy, rushing into our camp in great numbers, pressed hard on the legions. But Cæsar, seizing a shield and encouraging the soldiers, many of whose centurions had been slain, ordering them to extend their companies that they might more freely use their swords.
So great a change was soon effected that, though the enemy displayed great courage, the battle was ended so disastrously for them that the Nervii were almost annihilated. Scarcely five hundred were left who could bear arms. Their old men sent ambassadors to Cæsar by the consent of all who remained, surrendering themselves. The Aduatuci, before mentioned, who were coming to the help of the Nervii, returned home when they heard of this battle.
All Gaul being now subdued, so high an opinion of this war was spread among the barbarians that ambassadors were sent to Cæsar by those nations that dwelt beyond the Rhine, to promise that they would give hostages and execute his commands. He ordered these embassies to return to him at the beginning of the following summer, because he was hastening into Italy and Illyricum. Having led his legions into winter quarters among the Carnutes, the Andes, and the Turones, which states were close to those in which he had waged war, he set out for Italy, and a public thanksgiving of fifteen days was decreed for these achievements, an honour which before that time had been conferred on none.
III.--War by Land and Sea in Gaul
When Cæsar was setting out for Italy, he sent Servius Galba with the twelfth legion and part of the cavalry against the Nantuates, the Veragri, and the Seduni, who extend from the territories of the Allobroges and the Lake of Geneva and the River Rhone to the top of the Alps. The reason for sending him was that he desired that the pass along the Alps, through which the Roman merchants had been accustomed to travel with great danger, should be opened.
Galba fought several successful battles, stormed some of their forts, and concluded a peace. He then determined to winter in a village of the Veragri, which is called Octodurus. But before the winter camp could be completed the tops of the mountains were seen to be crowded with armed men, and soon these rushed down from all parts and discharged stones and darts on the ramparts.
