When being brought up it had cleared the walls of their defenders by means of the catapultae and ballistae ranged through all its stories, then Hannibal, thinking it a favourable opportunity, sends about five hundred Africans with pickaxes to undermine the wall: nor was the work difficult, since the unhewn stones were not fastened with lime, but filled in their interstices with clay, after the manner of ancient building.

It fell, therefore, more extensively than it was struck, and through the open spaces of the ruins troops of armed men rushed into the city.

They also obtain possession of a rising ground; and having collected thither catapultae and ballistae, so that they might have a fort in the city itself, commanding it like a citadel, they surround it with a wall: and the Saguntines raise an inner wall before the part of the city which was not yet taken.

On both sides they exert the utmost vigour in fortifying and fighting: but the Saguntines, by erecting these inner defences, diminish daily the size of their city.

At the same time, the want of all supplies increased through the length of the siege, and the expectation of foreign aid diminished, since the Romans, their only hope, were at such a distance, and all the country round was in the power of the enemy.
