army and "when he got near the Carthaginians and was in full sight of them he encamped on certain low hills opposite to the enemy." There is no mention of Baecula. Thus, this must have been at Ilipa and what both authors described was the Battle of Ilipa. In Polybius, Scipio found his situation embarrassing because the allied troops he had were not enough for him to risk a battle and it seemed dangerous to 'rely on the support of the allies in what promised to be a decisive engagement.' He was forced by circumstances to employ the natives, whose role would be to impress the enemy, while the actual fighting would be down to his legions. Livy wrote that while encamping, Scipio was attacked by Mago and Masinissa with the whole of their cavalry. Polybius specified that Mago thought it favourable to attack while the Romans were preparing their camp and that he would catch Scipio off guard. However, Scipio anticipated this and placed his cavalry, which was equal in numbers, under a hill. Caught by surprise, those who came close to the lines and attacked the parties digging the Roman entrenchments were routed. In Livy, the engagement with the other Carthaginians who were advancing in order was indecisive for a long time, while in Polybius the Carthaginian resistance was short. In Livy, the light infantry came out from the outposts and the entrenchment parties picked their weapons. More and more men came to relieve the wearied soldiers. The enemy withdrew in an orderly manner, but when they were pressed further they fled. Skirmishes between cavalry and light infantry on both sides to test each other's strength lasted for several days. After this, both sides lined up for battle in front of their camp until sunset and then returned to their camp. They repeated this for several days. As both sides had their own troops in the centre and the native auxiliaries on the wings Scipio thought that it was assumed that this would be the order of battle. Therefore, he changed the line-up for the day he intended to fight, placing the Romans on the wings. Polybius was more specific. He wrote that Scipio used two strategies, both consisted of acting in the opposite of the Carthaginians. One was a change of his line-up and the other was the timing of the battle. Hasdrubal repeatedly lined up the
