The armies were provided with the engines and materials necessary for the siege of the cities they might meet with in their expedition. If any natural obstructions impeded the approach to a castle, such as a forest or a river, they were, if possible, removed. Rivers were turned out of their courses, if they impeded the operations of the army; and warriors are frequently represented in the sculptures cutting down trees which surround a hostile city.
The first step in a siege was probably to advance the battering-ram. If the castle was built, as in the plains of Assyria and Babylonia, upon an artificial eminence, an inclined plane, reaching to the summit of the mound, was formed of earth, stones, or trees, and the besiegers were then able to bring their engines to the foot of the walls. This road was not unfrequently covered with bricks, forming a kind of paved way, up which the ponderous machines could be drawn without much difficulty.
This mode of reaching the walls of a city is frequently alluded to by the prophets, and is described by Isaiah: “Thus saith the Lord, concerning the king of Assyria, he shall not come into this city, nor shoot an arrow there, nor come before it with shields, nor cast a bank against it.” Similar approaches were used by the Egyptians. They not only enabled the besiegers to push their battering-rams up to the castle, but at the same time to escalade the walls, the summit of which might otherwise have been beyond the reach of their ladders.
The battering-rams were of several kinds. Some were joined to movable towers which held warriors and armed men. The whole then formed one great temporary building, the top of which is represented in the sculptures, as on a level with the walls, and even turrets, of the besieged city. In some bas-reliefs the battering-ram is without wheels; it was then perhaps constructed on the spot, and was not intended to be moved. The movable tower was probably sometimes unprovided with the ram; but I have not met with it so represented in the sculptures. When Nebuchadrezzar, king of Babylon, besieged Jerusalem, he “built forts against it round about.” These forts or towers, if stationary, were solidly constructed of wood; if movable, they consisted of a light frame covered with wickerwork. The Jews were forbidden to cut down and employ, for this purpose, trees which afford sustenance to man. “Only the trees which thou knowest that they be not trees for meat, thou shalt destroy and cut them down: and thou shalt build bulwarks against the city that maketh war with thee until it be subdued.”
When the machine containing the battering-ram consisted of a simple framework, not forming an artificial tower, a cloth of some kind of drapery edged with fringes and otherwise ornamented appears to have been occasionally thrown over it. Sometimes it may have been covered with hides. It moved either on four or on six wheels, and was provided with one ram or with two. The mode of working the rams cannot be determined from the Assyrian sculptures. It may be presumed, from the representations in the bas-reliefs, that they were partly suspended by a rope fastened to the outside of the machine, and that men directed and impelled them from within. Such was the plan adopted by the Egyptians, in whose paintings the warriors, working the ram, may be seen through the frame. Sometimes this engine was ornamented by a carved or painted figure of the presiding divinity, kneeling on one knee and drawing a bow. The artificial tower was usually occupied by two warriors: one discharged his arrows against the besieged, whom he was able from his lofty position to harass more effectually than if he had been below; the other held up a shield for his companion’s defence. Warriors are not unfrequently represented as stepping from the machine to the battlements.
Ezekiel alludes to all these modes of attack. “Lay siege against it,” he exclaims, speaking of the city of Jerusalem, “and build a fort against it, and cast a mount against it; set the camp also against it, and set battering-rams against it round about.”
Archers on the walls hurled stones from slings, and discharged their arrows against the warriors in the artificial towers; whilst the rest of the besieged were no less active in endeavouring to frustrate the attempts of the assailants to make breaches in their walls. By dropping a doubled chain or rope from the battlements, they caught the ram, and could either destroy its efficacy altogether or break the force of its blows. Those below, however, by placing hooks over the engine, and throwing their whole weight upon them, struggled to retain it in its place.
The besieged, if unable to displace the battering-ram, sought to destroy it by fire and threw lighted torches or firebrands upon it. But water was poured upon the flames, through pipes attached to the artificial tower. Other engines and instruments of war were employed by the besiegers. With a kind of catapult, apparently consisting of a light wooden frame covered with canvas or hides, they threw large stones and darts against the besieged, who, in their turn, endeavoured to set fire to it by torches. A long staff with an iron head, resembling a spear, was used to force stones out of the walls. Mines were also opened, and the assailants sought to enter the castle through concealed passages. Those who worked on them, or advanced to the attack, were perhaps protected by the testudo, as represented in the Egyptian paintings; but this defence is not seen in the Assyrian sculptures. Attempts were made to set fire to the gates of the city by placing torches against them, or to break them open with axes.
