41. In the same year operations in Spain were chequered. For Mago and Hasdrubal, before the Romans should cross the Ebro, routed immense forces of Spaniards. [2] And Farther Spain would have revolted from the Romans if Publius Cornelius had not hastily led his army across the Hiberus and arrived in the nick of time, while the allies were still wavering. [3] At first the Romans had their camp at Castrum Album,¹ noted as the place where the great Hamilcar fell. [4] The citadel had been fortified and they had previously brought in grain. Yet the country all around was filled with the enemy, and the Roman column had been attacked with impunity by the enemy's cavalry and about two thousand men, either straggling or scattered over the farms, had been slain. The Romans therefore retired from the place to a position nearer peaceful regions and fortified a camp at Victory Mountain.² [5] Thither came Gnaeus Scipio with all his troops, and Hasdrubal the son of Gisgo, making three Carthaginian generals and a complete army; and all three established themselves across [p. 309]the river, opposite the Roman camp. [6] Publius³ Scipio, who set out secretly to reconnoitre with unencumbered troops, did not escape the notice of the enemy, and they would have overwhelmed him in the open meadows if he had not captured a hill near by. [7] Even there he was beset, but by the arrival of his brother he escaped a siege. Castulo⁴ revolted to the Romans, a strong and famous city of Spain, so closely joined to the Carthaginians by alliance that Hannibal's wife⁵ was from that place. [8] The Carthaginians attempted to capture Iliturgis,⁶ because there was a Roman garrison there, and it seemed that they would take the town mainly by starvation. [9] Gnaeus Scipio, to lend aid to the allies and the garrison, set out with an unencumbered legion, passing between their two camps, and after slaying many of the enemy entered the city, and on the following day engaged them in an equally successful sally. [10] Over twelve thousand men were slain in the two battles, more than a thousand men captured, with thirty-six military standards. So they withdrew from Iliturgis. [11] Then began the siege of Bigerra⁷ —these also were allies of the Romans —by the Carthaginians. Gnaeus Scipio on his arrival raised the siege without an engagement.
