it was sure to disorder the forces that did so. Cavalry skirmishes began the battle, although neither force crossed the marsh. Caesar claims his forces came out favourably in these initial actions, and so led his forces back to his camp. Second Phase: Belgic repositioning and main engagement After Caesar's manoeuver the Belgic forces circumvented the camp and endeavoured to approach it from behind. The rear of the camp was bordered by the river Axona (today called the River Aisne), and the Belgae sought to attack the camp via a single fording spot in the river. Caesar claims their intention was to lead a part of their force over the bridge, and either take the camp by storm, or cut the Romans off from the lands on the opposite side of the river. This tactic would both deprive the Romans of land for foraging, and prevent them from coming to the aid of the Remi tribe whose lands the Belgae had the intention of pillaging (as mentioned in the Prelude, above). To counter this manoeuver, Caesar sent all his light infantry and cavalry to manage the difficult terrain (as it would have been more difficult for the heavy infantry to do so). This action is described in his Gallic Wars at 2.10: Caesar, being apprized of [the situation] by Titurius [his legate], leads all his cavalry and light-armed Numidians, slingers and archers, over the bridge, and hastens toward them. There was a severe struggle in that place. Our men, attacking in the river the disordered enemy, slew a great part of them. By the immense number of their missiles they drove back the rest, who, in a most courageous manner were attempting to pass over their bodies, and surrounded with their cavalry, and cut to pieces those who had first crossed the river. Dismayed by the courageous attack by Caesar's men, and by their consequent inability to either take the camp by storm or blockade the Romans from crossing the river, the Belgic forces withdrew to their camp. Then, calling a council of war, they immediately resigned to returning to their home territories, where they might better be able to engage Caesar's invading army. Aftermath So rushed and unorganized was the Belgic departure from their camp, that it seemed very much like a panicked retreat to the Roman forces. However, as Caesar was as yet unaware of their reason for
