While the mutiny was going on in the Roman army, a certain Indibilis, one of the chiefs who had come to an understanding with Scipio, made an incursion into the territory of Scipio's allies. When Scipio marched against him he made a very stiff fight, and killed some 1200 of the Romans, but having lost 20,000 of his own men he sued for peace. Scipio made him pay a fine, and then came to an agreement with him. At this time also Masinissa crossed the straits, without the knowledge of Hasdrubal, and established friendly relations with Scipio, and swore to join him if the war should be carried into Africa. This man remained faithful under all circumstances and for the following reason. The daughter of Hasdrubal had been betrothed to him while he was fighting under the latter's command. But King Syphax was desperately in love with the same girl, and the Carthaginians, considering it a matter of great moment to secure Syphax against the Romans, gave her to him without consulting Hasdrubal. The latter, when he heard of it, concealed it from Masinissa out of regard for him. When Masinissa learned the facts he made an alliance with Scipio. Mago, the admiral, despairing of Carthaginian success in Spain, sailed to the country of the Ligurians and the Gauls to recruit mercenaries. While he was absent on this business the Romans took possession of Gades, which he had abandoned.
