Subjugation of the Belgae
After this annihilating defeat the Nervii, Atrebates, and Viromandui could not but recognize the Roman supremacy. The Aduatuci, who arrived too late to take part in the fight on the Sambre, attempted still to hold their ground in the strongest of their towns (on the mount Falhize near the Maas not far from Huy), but they too soon submitted. A nocturnal attack on the Roman camp in front of the town, which they ventured after the surrender, miscarried; and the perfidy was avenged by the Romans with fearful severity. The clients of the Aduatuci, consisting of the Eburones between the Maas and Rhine and other small adjoining tribes, were declared independent by the Romans, while the Aduatuci taken prisoners were sold under the hammer en masse for the benefit of the Roman treasury.
It seemed as if the fate which had befallen the Cimbri still pursued even this last Cimbrian fragment. Caesar contented himself with imposing on the other subdued tribes a general disarmament and furnishing of hostages. The Remi became naturally the leading canton in Belgic, like the Haedui in central Gaul; even in the latter several clans at enmity with the Haedui preferred to rank among the clients of the Remi. Only the remote maritime cantons of the Morini (Artois) and the Menapii (Flanders and Brabant), and the country between the Scheldt and the Rhine inhabited in great part by Germans, remained still for the present exempt from Roman invasion and in possession of their hereditary freedom.
