Fabius at Tarentum, to the effect, that they would accept of his promise that their past conduct should be unpunished, on condition of their betraying Metapontum together with the Carthaginian garrison into his hands. Fabius, who supposed that the communication they brought was genuine, appointed a day on which he would go to Metapontum, and gave the letters to the nobles, which were put into the hands of Hannibal. He, forsooth, delighted at the success of his stratagem, which showed that not even Fabius was proof against his cunning, planted an ambuscade not far from Metapontum. But when Fabius was taking the auspices, before he took his departure from Tarentum, the birds more than once refused approval. Also, on consulting the gods after sacrificing a victim, the aruspex forewarned him to be on his guard against hostile treachery and ambuscade. After the day fixed for his arrival had passed without his coming, the Metapontines were sent again to encourage him, delaying, but they were instantly seized, and, from apprehension of a severer mode of examination, disclosed the plot. 17.

Hasdrubal, perceiving that the strength of the enemy was increasing by such large accessions, while his own was diminishing, and that events would continue to flow in the same course they had taken, unless by a bold effort he effected some alteration, resolved to come to an engagement as soon as possible. Scipio was still more eager for a battle, as well from hope which the success attending his operations had increased, as because he preferred, before the junction of the enemy's forces, to fight with one general and one army, rather than with their united troops. However, in case he should be obliged to fight with more armies than one at the same time, he had with some ingenuity augmented his forces; for seeing that there was no necessity for ships, as the whole coast of Spain was clear of Carthaginian fleets, he hauled his ships on shore at Tarraco and added his mariners to his land forces. He had plenty of arms for them, both those which had been captured at
