+13.+ Meanwhile Publius, though throwing himself heartily into the struggle, yet took all possible precautions to protect his life. He had three men with him carrying large shields, which they held in such a position as to completely protect him from the side of the wall; and accordingly he went along the lines, or mounted on elevated ground, and contributed greatly to the success of the day. For he was enabled to see all that was going on, and at the same time, by being himself in view of all, inspired great zeal in the hearts of the combatants. The result was that nothing was omitted which could contribute to the success of the battle; but any help he saw to be at any moment required was rapidly and thoroughly supplied. [Sidenote: Difficulties of the escalade.] But though the leaders of the escalade had begun mounting the walls with great spirit, they found the operation accompanied by some danger: not so much from the number of the defenders, as from the height of the walls. The defenders accordingly plucked up courage considerably when they saw the distress of the assailants: for some of the ladders were breaking under the weight of the numbers which, owing to their length, were on them at the same time; while on others the first to mount turned giddy owing to their great height, and without requiring much resistance from the defenders threw themselves from the ladders: and when beams, or anything of that sort, were hurled upon them from the battlements, they were swept off _en masse_ and fell to the ground. In spite however of these difficulties nothing could check the zeal and fury of the Roman attack; but as the first fell their place was always taken at once by the next in order. And now, as the day was far advanced, and the soldiers were worn out with fatigue, Scipio sounded a recall for the assaulting party.
