39. Very opportunely for the commencement of his operations, a war had broken out with the Taurini, the nearest nation, against the Insubrians; but Hannibal could not put his troops under arms to assist either party, as they now chiefly felt the disorders they had before contracted, in remedying them; [2] for ease after toil, plenty after want, and attention to their persons after dirt and filth, had variously affected their squalid and almost savage-looking bodies. [3] This was the reason that Publius Cornelius, the consul, when he had arrived at Pisa with his fleet, hastened to the Po, though the troops he received from Manlius and Atilius were raw and disheartened by their late disgraces, in order that he might engage the enemy when not yet recruited.

[10] Scipio, however, [p. 738]was the first to cross the Po, and having pitched his camp at the river Ticinus, he delivered the following oration for the sake of encouraging his soldiers before he led them out to form for battle:
