These figures look inflated, especially given that Polybius estimated only 10,000 Carthaginian and Gallic dead. Modern estimates suggest Hasdrubal's army was about 30,000 in strength, and Marcus Livius' army of roughly equal numbers. The propraetor L. Porcius Licinius commanded two legions—as many men as the consul. This means that Marcus Livius and Porcius Licinius had between them four legions, i.e. 32,000–40,000 men, including their allies. The numbers of the allied contingents could have been less than usual due to the refusal of some of the Roman clients to provide auxiliaries. Porcius' legions were under-strength. The Roman force was probably further diminished by earlier fighting with Hasdrubal, the evidence of which is the presence of 3,000 prisoners in Hasdrubal's camp. Claudius Nero's 7,000 troops were joined by perhaps 2,000 volunteers en route, and upon his arrival the Romans had 37,000 men concentrated against Hasdrubal.
