Whilst Pompey was thus busy in the affairs and government of Sicily, he received a decree of the senate, and a commission from Sylla, commanding him forthwith to sail into Africa, and make war upon Domitius with all his forces: for Domitius had rallied up a far greater army than Marius had had not long since, when he sailed out of Africa into Italy, and caused a revolution in Rome, and himself, of a fugitive outlaw, became a tyrant. Pompey, therefore, having prepared everything with the utmost speed, left Memmius, his sister's husband, governor of Sicily, and set sail with one hundred and twenty galleys, and eight hundred other vessels laden with provisions, money, ammunition, and engines of battery. He arrived with his fleet, part at the port of Utica, part at Carthage; and no sooner was he landed, but seven thousand of the enemy revolted and came over to him, while his own forces that he brought with him consisted of six entire legions. Here they tell us of a pleasant incident that happened to him at his first arrival.
Some of his soldiers having by accident stumbled upon a treasure, by which they got a good sum of money, the rest of the army hearing this, began to fancy that the field was full of gold and silver, which had been hid there of old by the Carthaginians in the time of their calamities, and thereupon fell to work, so that the army was useless to Pompey for many days, being totally engaged in digging for the fancied treasure, he himself all the while walking up and down only, and laughing to see so many thousands together, digging and turning up the earth. Until at last, growing weary and hopeless, they came to themselves and returned to their general, begging him to lead them where he pleased, for that they had already received the punishment of their folly.
By this time Domitius had prepared himself and drawn out his army in array against Pompey; but there was a watercourse betwixt them, craggy, and difficult to pass over; and this, together with a great storm of wind and rain pouring down even from break of day, seemed to leave but little possibility of their coming together; so that Domitius, not expecting any engagement that day, commanded his forces to draw off and retire to the camp. Now Pompey, who was watchful upon every occasion, ****** use of the opportunity, ordered a march forthwith, and having passed over the torrent, fell in immediately upon their quarters. The enemy was in great disorder and tumult, and in that confusion attempted a resistance; but they neither were all there, nor supported one another; besides, the wind having veered about beat the rain full in their faces. Neither indeed was the storm less troublesome to the Romans, for that they could not clearly discern one another, insomuch that even Pompey himself, being unknown, escaped narrowly; for when one of his soldiers demanded of him the word of battle, it happened that he was somewhat slow in his answer, which might have cost him his life.
The enemy being routed with a great slaughter (for it is said that of twenty thousand there escaped but three thousand), the army saluted Pompey by the name of Imperator; but he declined if, telling them that he could not by any means accept of that title as long as he saw the camp of the enemy standing; but if they designed to make him worthy of the honour, they must first demolish that. The soldiers on hearing this went at once and made an assault upon the works and trenches, and there Pompey fought without his helmet, in memory of his former danger, and to avoid the like. The camp was thus taken by storm, and among the rest Domitius was slain. After that overthrow, the cities of the country thereabouts were all either secured by surrender, or taken by storm. King Iarbas, likewise, a confederate and auxiliary of Domitius, was taken prisoner, and his kingdom was given to Hiempsal.
Pompey could not rest here, but being ambitious to follow the good fortune and use the valour of his army, entered Numidia; and marching forward many days' journey up into the country, he conquered all where-ever he came. And having revived the terror of the Roman power, which was now almost obliterated among the barbarous nations, he said likewise, that the wild beasts of Africa ought not to be left without some experience of the courage and success of the Romans, and therefore he bestowed some few days in hunting lions and elephants. And it is said that it was not above the space of forty days at the utmost in which he gave a total overthrow to the enemy, reduced Africa, and established the affairs of the kings and kingdoms of all that country, being then in the twenty-fourth year of his age.
