Metellus, seeing that the people of Thala were determined on resistance, and that the town was defended both by art and situation, surrounded the walls with a rampart and a trench. He then directed his machines against the most eligible points, threw up a mound, and erected towers upon it to protect[208] the works and the workmen. The townsmen, on the other hand, were exceedingly active and diligent; and nothing was neglected on either side. At last the Romans, though exhausted with much previous fatigue and fighting, got possession, forty days after their arrival, of the town, and the town only; for all the spoil had been destroyed by the deserters; who, when they saw the walls shaken by the battering-ram, and their own situation desperate, had conveyed the gold and silver, and whatever else is esteemed valuable, to the royal palace, where, after being sated with wine and luxuries, they destroyed the treasures, the building, and themselves, by fire, and thus voluntarily submitted to the sufferings which, in case of being conquered, they dreaded at the hands of the enemy. LXXVII. At the very time that Thala was taken, there came to Metellus embassadors from the city of Leptis,[209] requesting him to send them a garrison and a governor; saying "that a certain Hamilcar, a man of rank, and of a factious disposition, against whom the magistrates and the laws were alike powerless, was trying to induce them to change sides; and that unless he attended to the matter promptly, their own safety,[210] and the allies of Rome, would be in the utmost danger." For the people at Leptis, at the very commencement of the war with Jugurtha, had sent to the consul Bestia, and afterward to Rome, desiring to be admitted into friendship and alliance with us. Having been granted their request, they continued true and faithful adherents to us, and promptly executed all orders from Bestia, Albinus, and Metellus. They therefore readily obtained from the general the aid which they solicited; and four cohorts of Ligurians were dispatched to Leptis, with Caius Annius to be governor of the place. LXXVIII. This city was built by a party of Sidonians, who, as I have understood, being driven from their country through civil dissensions, came by sea into those parts of Africa. It is situated between the two Syrtes, which take their name from their nature[211] These are two gulfs almost at the extremity of Africa[212] of unequal size, but of similar character. Those parts of them next to the land are very deep; the other parts sometimes deep and sometimes shallow, as chance may direct; for when the sea swells, and is agitated by the winds, the waves roll along with them mud, sand, and huge stones; and thus the appearance of the gulfs changes with the direction of the wind.
