Drawn by Faucher-Gudin, from one of the bronze bas-reliefs of the gate of Balawat. The battering-rams were set up and placed in line at a short distance from the ramparts of the besieged town; the ground in front of them was then levelled and a regular causeway constructed, which was paved with bricks wherever the soil appeared to be lacking in firmness. These preliminaries accomplished, the engines were pushed forward by relays of troops till they reached the required range. The effort needed to set the ram in motion severely taxed the strength of those engaged in the work; for the size of the beam was enormous, and its iron point, or the square mass of metal at the end, was of no light weight. The besieged did their best to cripple or, if possible, destroy the engine as it approached them.

Torches, lighted tow, burning pitch, and stink-pots were hurled down upon its roofing: attempts were made to seize the head of the ram by means of chains or hooks, so as to prevent it from moving, or in order to drag it on to the battlements; in some cases the garrison succeeded in crushing the machinery with a mass of rock. The Assyrians, however, did not allow themselves to be discouraged by such trifling accidents; they would at once extinguish the fire, release, by sheer force of muscle, the beams which the enemy had secured, and if, notwithstanding all their efforts, one of the machines became injured, they had others ready to take its place, and the ram would be again at work after only a few minutes' delay. Walls, even when of burnt brick or faced with small stones, stood no chance against such an attack.

The first blow of the ram sufficed to shake them, and an opening was rapidly made, so that in a few days, often in a few hours, they became a heap of ruins; the foot soldiers could then enter by the breach which the pioneers had effected.
