The sudden approach of the cavalry to their camp, and the simultaneous appearance of the rest of the army getting into order, left the Carthaginians barely time to get under arms. Hasdrubal was therefore obliged, without waiting for the men to get breakfast, or making any preparations, to despatch his cavalry and light-armed troops at once against the enemy’s cavalry on the plain, and to get his infantry into order on some level ground not far from the skirts of the mountains, as was their custom. For a time the Romans remained quiet; but when the morning was getting on, and the engagement between the light-armed troops still continued undecided, because such of them as were forced from their ground retired on their own heavy infantry and then formed again for attack, Scipio at length thought that the time was come. He withdrew his skirmishers through the intervals of the maniples, and then distributed them equally between the two wings on rear of his line, first the velites and behind them the cavalry. He then advanced, at first in line direct; but when he was about a stade[23] from the enemy, he ordered the Iberians to continue the advance in the same order, while he commanded the maniples and squadrons on the right wing to turn outwards to the right, and those on the left wing to the left. +23.+ Scipio with the three leading squadrons of cavalry from the right wing, preceded by the usual number of velites and three maniples (a combination of troops which the Romans call a cohort), and Lucius Marcius and Marcus Junius with a similar force from the left wing, turned the one to the left the other to the right, and advanced at a great speed in column upon the enemy, the troops in succession forming up and following in column as they wheeled. When these troops were within a short distance of the enemy,—the Iberians in the line direct being still a considerable distance behind, because they were advancing at a deliberate pace,—they came into contact with the two wings of the enemy simultaneously, the Roman forces being in column, according to Scipio’s original plan. The movements subsequent to this, which resulted in the troops on the rear finding themselves in the same line as the troops in front, and engaged like them with the enemy, were exactly the converse of each other—taking the right and left wings in general, and the cavalry and infantry in particular. For the cavalry and velites on the right wing came into line on the right and tried to outflank the enemy, while the heavy infantry came into line on the left; but on the left wing the heavy infantry came into line by the right, the cavalry and velites by the left. The result of this movement was that, as far as the cavalry and light infantry were concerned, their right became their left. Scipio cared little for this, but was intent on something more important, namely, the outflanking of the enemy. For while a general ought to be quite alive to what is taking
