V. The day after the flight of the enemy, before they had recovered from their fright, Cæsar broke up his camp, crossed the Aisne, descended its left bank, invaded the country of the Suessiones, arrived after a long day’s march (45 kilomètres) before Noviodunum (Soissons) (see Plate 7), and, informed that this town had a weak garrison, he attempted the same day to carry it by assault; he failed, through the breadth of the fosses and the height of the walls. He then retrenched his camp, ordered covered galleries to be advanced (vineas agere),[253] and all things necessary for a siege to be collected. Nevertheless, the crowd of fugitive Suessiones threw themselves into the town during the following night. The galleries having been pushed rapidly towards the walls, the foundations of a terrace[254] to pass the fosse (aggere jacto) were established, and towers were constructed. The Gauls, astonished at the greatness and novelty of these works, so promptly executed, offered to surrender. They obtained safety of life at the prayer of the Remi.

Cæsar received as hostages the principal chiefs of the country, and even the two sons of King Galba, exacted the surrender of all their arms, and accepted the submission of the Suessiones. He then conducted his army into the country of the Bellovaci, who had shut themselves up, with all they possessed, in the oppidum of Bratuspantium (Breteuil).[255] The army was only at about five miles’ distance from it, when all the aged men, issuing from the town, came, with extended hands, to implore the generosity of the Roman general; when he had arrived under the walls of the place, and while he was establishing his camp, he saw the women and children also demanding peace as suppliants from the top of the walls.

Divitiacus, in the name of the Ædui, interceded in their favour. After the retreat of the Belgæ and the disbanding of his troops, he had returned to the presence of Cæsar. The latter, who had, at the prayer of the Remi, just shown himself clement towards the Suessiones, displayed, at the solicitation of the Ædui, the same indulgence towards the Bellovaci. Thus obeying the same political idea of increasing among the Belgæ the influence of the peoples allied to Rome, he pardoned them; but, as their nation was the most powerful in Belgic Gaul, he required from them all their arms and 600 hostages. The Bellovaci declared that the promoters of the war, seeing the misfortune they had drawn upon their country, had fled into the isle of Britain.

It is curious to remark the relations which existed at this epoch between part of Gaul and England. We know, in fact, from the “Commentaries,” that a certain Divitiacus, an Æduan chieftain, the most powerful in all Gaul, had formerly extended his power into the isle of Britain, and we have just seen that the chiefs in the last struggle against the Romans had found a refuge in the British isles.

Cæsar next marched from Bratuspantium against the Ambiani, who surrendered without resistance.[256]

March against the Nervii.

VI. The Roman army was now to encounter more formidable adversaries. The Nervii occupied a vast territory, one extremity of which touched upon that of the Ambiani. This wild and intrepid people bitterly reproached the other Belgæ for having submitted to foreigners and abjured the virtues of their fathers. They had resolved not to send deputies, nor to accept peace on any condition. Foreseeing the approaching invasion of the Roman army, the Nervii had drawn into alliance with them two neighbouring peoples, the Atrebates and the Veromandui, whom they had persuaded to risk with them the fortune of war: the Aduatuci, also, were already on the way to join the coalition. The women, and all those whose age rendered them unfit for fighting, had been placed in safety, in a spot defended by a marsh, and inaccessible to an army, no doubt at Mons.[257]

After the submission of the Ambiani, Cæsar left Amiens to proceed to the country of the Nervii; and after three days’ march on their territory, he arrived probably at Bavay (Bagacum), which is considered to have been their principal town. There he learnt by prisoners that he was no more than ten miles (fifteen kilomètres) distant from the Sambre, and that the enemy awaited him posted on the opposite bank of the river.[258] He thus found himself on the left bank, and the Nervii were assembled on the right bank.[259] (See Plate 7.)

In accordance with the informations he had received, Cæsar sent out a reconnoitring party of scouts and centurions, charged with the selection of a spot favourable for the establishment of a camp. A certain number of the Belgæ, who had recently submitted, and other Gauls, followed him, and accompanied him in his march. Some of them, as was known subsequently by the prisoners, having observed during the preceding days the usual order of march of the army, deserted during the night to the Nervii, and informed them that behind each of the legions there was a long column of baggage; that the legion which arrived first at the camp being separated by a great space from the others, it would be easy to attack the soldiers, still charged with their bundles (sarcinæ); that this legion once routed and its baggage captured, the others would not dare to offer any resistance. This plan of attack was the more readily embraced by the Belgæ, as the nature of the locality favoured its execution. The Nervii, in fact, always weak in cavalry (their whole force was composed of infantry), were accustomed, in order to impede more easily the cavalry of their neighbours, to notch and bend horizontally young trees, the numerous branches of which, interlaced and mingled with brambles and brushwood, formed thick hedges, a veritable wall which nothing could pass through, impenetrable even to the eye.[260] As this kind of obstacle was very embarrassing to the march of the Roman army, the Nervii resolved to hide themselves in the woods which then covered the heights of Haumont, to watch there the moment when it would debouch on the opposite heights of the Sambre, to wait till they perceived the file of baggage, and then immediately to rush upon the troops which preceded.[261] (See Plate 10.)
