So Hannibal mustered his forces and continued the descent; and on the third day after passing the precipitous path just described he reached the plains. From the beginning of his march he had lost many men by the hands of the enemy, and in crossing rivers, and many more on the precipices and dangerous passes of the Alps; and not only men in this last way, but horses and beasts of burden in still greater numbers. The whole march from New Carthage had occupied five months, the actual passage of the Alps fifteen days; and he now boldly entered the valley of the Padus, and the territory of the Insubres, with such of his army as survived, consisting of twelve thousand Libyans and eight thousand Iberians, and not more than six thousand cavalry in all, as he himself distinctly states on the column erected on the promontory of Lacinium to record the numbers. At the same time, as I have before stated, Publius having left his legions under the command of his brother Gnaeus, with orders to prosecute the Iberian campaign and offer an energetic resistance to Hasdrubal, landed at Pisae with a small body of men. Thence he marched through Etruria, and taking over the army of the Praetors which was guarding the country against the Boii, he arrived in the valley of the Padus; and, pitching his camp there, waited for the enemy with an eager desire to give him battle.
