Dionysius opened the campaign with the siege of Motya, which was the magazine of the Carthaginians in Sicily; and he pushed on the siege with so much vigour, that it was impossible for Imilcon, the Carthaginian admiral, to relieve it. He brought forward his engines, battered the place with his battering-rams, advanced to the wall towers, six stories high (rolled upon wheels,) and of an equal height with their houses; and from these he greatly annoyed the besieged, with his Catapultæ, an engine(622) then recently invented, which hurled, with great violence, numerous volleys of arrows and stones against the enemy. At last, the city, after a long and vigorous defence, was taken by storm, and all the inhabitants of it put to the sword, those excepted who took sanctuary in the temples. The plunder of it was abandoned to the soldiers, and Dionysius, leaving a strong garrison and a trusty governor in it, returned to Syracuse. The following year Imilcon being appointed one of the Suffetes, returned to Sicily with a far greater army than before.(623) He landed at Palermo,(624) recovered Motya by force, and took several other cities. Animated by these successes, he advanced towards Syracuse, with design to besiege it; marching his infantry by land, whilst his fleet, under the command of Mago, sailed along the coast. The arrival of Imilcon threw the Syracusans into great consternation. Above two hundred ships laden with the spoils of the enemy, and advancing in good order, entered in a kind of triumph the great harbour, being followed by five hundred barks. At the same time, the land army, consisting, according to some authors, of three hundred thousand foot,(625) and three thousand horse, was seen marching forward on the other side of the city. Imilcon pitched his tent in the very temple of Jupiter; and the rest of the army encamped at twelve furlongs, or about a mile and a half from the city. Marching up to it, Imilcon offered battle to the inhabitants, who did not care to accept the challenge. Imilcon, satisfied at his having extorted from the Syracusans this confession of their own weakness and his superiority, returned to his camp; not doubting but he should soon be master of the city, considering it already as a certain prey which could not possibly escape him. For thirty days together, he laid waste the neighbourhood about Syracuse, and ruined the whole country. He possessed himself of the suburb of Acradina, and plundered the temples of Ceres and Proserpine. To fortify his camp, he beat down the tombs which stood round the city; and, among others, that of Gelon and his wife Demarata, which was prodigiously magnificent.
