Claudius Nero, on the Roman right flank, struggled to overcome the terrain that blocked his path to the unwary Gauls on Hasdrubal's left. Seeing the futility in wasting further time attempting to reach the inert Gauls, he instead took half of his men in cohorts and led them from behind the battling Roman lines to the extreme Roman left, swinging his troops around and crashing into the Carthaginian right flank with sudden force and intensity. The Carthaginian right wing, composed of Hispanics, could not withstand this two pronged attack of Marcus Livius from the front and Claudius Nero on their flank. They were forced to fall back, taking the Ligures in the Carthaginian centre with them. The elephants were running amok, killing Romans and Carthaginians alike. Hasdrubal fought alongside his men and exhorted them to keep fighting, rallying fleeing soldiers and re-starting the battle wherever he was present.
