II. Having thus rendered all retreat impossible to Ambiorix, he advanced with his army towards the country of Liége by way of Zulpich and Eupen, across the forest of the Ardennes. Having arrived on the Meuse, he divided his troops into three corps, and sent all his baggage with the 14th legion, under the command of Cicero, into the fortress of Tongres, the scene of the disaster of Sabinus. Of these three corps, the first was sent towards the north, near the southern frontiers of Brabant; the second towards the west, between the Meuse and the Demer; and the third marched towards the Scheldt, under the command of Cæsar, whose intention was to gain the extremity of the forest of the Ardennes between Brussels and Antwerp, where Ambiorix was said to have taken refuge. When he quitted Tongres, he announced that he should return in seven days. But, unwilling to risk his troops on difficult ground, against men who, scattered, carried on a war of partisans, he sent messengers to invite the neighbouring peoples to go and ravage the country of Liége, and, at his call, all hurried to take part in the pillage. Among them 2,000 Sicambrian cavalry, attracted from beyond the Rhine, conceived the idea of falling upon Cicero’s camp in order to carry off the riches it contained. They arrived at the moment when a part of the garrison had gone to forage. It was with great difficulty, and with the loss of two cohorts, that the Romans repulsed this attack. The devastation of the country of Liége was completed, but Ambiorix escaped. The defeat of Sabinus at Tongres thus cruelly avenged, Cæsar returned to Rheims, convoked there the assembly of Gaul, and caused judgment to be passed on the conspiracy of the peoples of Sens and Orleans. Acco, the head of the revolt, was condemned to death and executed, and Cæsar, after placing his legions in winter quarters in the countries watered by the Moselle, the Marne, and the Yonne, repaired to Italy.

The year 700 had closed without the holding of the consular comitia. Sometimes the tribunes of the people, the only magistrates whose elections took place on a fixed day, opposed the holding of the comitia; sometimes the _interreges_ themselves failed to obtain favourable auspices, or, in moments of trouble, dared not assemble the people.[716] The boldness of the agitators of all parties explains this anarchy.
