After this, it seemed probable that the remainder of the summer would be peaceful; [2] and so it would have been with regard to the Punic enemy: but besides that the tempers of the Spaniards themselves are naturally restless, and eager for innovation, Mandonius, together with Indibilis, who had formerly [3??] been petty prince of the Ilergetes, having stirred up their countrymen, came to lay waste the peaceful country of the Roman allies, after the Romans had retired from the pass to the sea-coast. [4] A military tribune with some light-armed [p. 789]auxiliaries being sent against these by Scipio, with a small effort put them all to the rout, as being but a disorderly band: some having been captured and slain, a great portion of them were deprived of their arms. [5] This disturbance, however, brought back Hasdrubal, who was retiring to the ocean, to protect his allies on this side the Iberus. [6] The Carthaginian camp was in the territory of Ilercao, the Roman camp at the New Fleet, when unexpected intelligence turned the war into another quarter. [7] The Celtiberians, who had sent the chief men of their country as ambassadors to the Romans, and had given them hostages, aroused by a message from Scipio, take up arms and invade the province of the Carthaginians with a powerful army; [8] take three towns by storm; and after that, encountering Hasdrubal himself in two battles with splendid success, slew fifteen thousand and captured four thousand, together with many military standards.
