But the consequences of the victory were not confined to this.

As Caesar advanced into the western cantons of the Belgae, one after another gave themselves up as lost almost without resistance; the powerful Suessiones (about Soissons), as well as their rivals, the Bellovaci (about Beauvais) and the Ambiani (about Amiens).

The towns opened their gates when they saw the strange besieging machines, the towers rolling up to their walls; those who would not submit to the foreign masters sought a refuge beyond the sea in Britain.
The Conflict with the Nervii But in the eastern cantons the national feeling was more energetically roused.

The Viromandui (about Arras), the Atrebates (about St.Quentin), the German Aduatuci (about Namur), but above all the Nervii (in Hainault) with their not inconsiderable body of clients, little inferior in number to the Suessiones and Bellovaci, far superior to them in valour and vigorous patriotic spirit, concluded a second and closer league, and assembled their forces on the upper Sambre.

Celtic spies informed them most accurately of the movements of the Roman army; their own local knowledge, and the high tree-barricades which were formed everywhere in these districts to obstruct the bands of mounted robbers who often visited them, allowed the allies to conceal their own operations for the most part from the view of the Romans.
