to form a barricade. The gaps were filled with kits and packages. As it was difficult to clamber over it, remove the heavy obstacles or cut through the tightly packed saddles, the enemy was delayed for a considerable amount of time. However, they managed to make several openings. The Romans were slaughtered, but a good many managed to escape. Gnaeus Scipio was killed 29 days after his brother. The Roman defeat was almost total and they would have been driven out of Hispania had it not been for Lucius Marcius, an officer who rallied the remnant of the routed forces, assembled a force and joined Tiberius Fonteius, who had been left in charge of Publius Scipio's camp. They pitched a camp north of the Ebro and the soldiers elected Lucius Marcius as their commander. The defences were strengthened and supplies were stored. Hasdrubal Gisgo crossed the Ebro. When the enemy approached, Lucius Marcius gave the battle signal, which caught the Carthaginians by surprise. The Roman army had been annihilated and they wondered where these men were from and who their commander was. They slowly withdrew and as the attack became more consistent they fled. Lucius Marcius withdrew. Lucius Marcius noticed that the Carthaginians were careless in guarding their camps and devised a plan. He considered that it was easier to attack Hasdrubal's camp while he was alone, before the three Carthaginian commanders might unite – the other Carthaginian camps were six miles beyond Hasdrubal's. A Roman contingent with some cavalry hid in a thickly wooded valley between the enemy camps, which cut off the road. The rest marched to the camp quietly at night. There were no outposts nor guards and they entered without opposition. The enemy were killed while half asleep. The Romans then went to the second camp where there was carelessness, too. The men at the outposts were unarmed. The Romans attacked and their shields were bloodied by the previous battle. This frightened the enemy, who fled. Those who were not killed were driven out of the camp. Livy noted that, according to one source, as many as 37,000 of the enemy were killed and 1,830 were captured. Another source held that only Mago's camp was taken, that 7,000 of the enemy were killed and that the battle against Hasdrubal was a sortie; here 10,000 were killed and 4,380 were captured. According to a third source 5,000
