Whilst time was thus being wasted in disputes instead of deliberation, Hannibal withdrew the bulk of his army, who had been standing most of the day in order of battle, into camp. [2] He sent his Numidians, however, across the river to attack the parties who were getting water for the smaller camp. [3] They had hardly gained the opposite bank when with their shouting and uproar they sent the crowd flying in wild disorder, and galloping on as far as the outpost in front of the rampart, they nearly reached the gates of the camp. [4] It was looked upon as such an insult for a Roman camp to be actually terrorised by irregular auxiliaries that one thing, and one thing alone, held back the Romans from instantly crossing the river and forming their battle line-the supreme command that day rested with Paulus. [5] The following day Varro, whose turn it now was, without any consultation with his colleague, exhibited the signal for battle and led his forces drawn up for action across the river. Paulus followed, for though he disapproved of the measure, he was bound to support it. [6] After crossing, they strengthened their line with the force in the smaller camp and completed their formation. [7] On the right, which was nearest to the river, the Roman cavalry were posted, then came the infantry; on the extreme left were the cavalry of the allies, their infantry were between them and the Roman legions. The javelin men with the rest of the light-armed auxiliaries formed the front line. [8] The consuls took their stations on the wings, Terentius Varro on the left, Aemilius Paulus on the right.
