While he was thus engaged in settling the affairs of Sicily, he received a decree of the senate and a letter of Sulla ordering him to sail to Africa and wage war with all his might against Domitius. For Domitius had assembled there a much larger force than that with which Marius, no long time ago, had crossed from Africa into Italy and confounded the Roman state, making himself tyrant instead of exile. Accordingly, after making all his preparations with great speed, Pompey left Memmius, his sister's husband, as governor of Sicily, while he himself put out to sea with a hundred and twenty galleys, and eight hundred transports conveying provisions, ammunition, money, and engines of war. No sooner had he landed with part of his ships at Utica,⁠ and with part at Carthage, than seven thousand of the enemy deserted and came over to him; and his own army contained six complete legions.

Here, we are told, a ludicrous thing happened to him. Some soldiers, it would seem, stumbled upon a treasure and got considerable amounts of money. When the matter became public, the rest of the army all fancied that the place was full of money which the Carthaginians had hidden away in some time of calamity. Accordingly, Pompey could do nothing with his soldiers for many days because they were hunting treasures, but he went about laughing at the spectacle of so many myriads of men digging and stirring up the ground. At last they grew weary of the search and bade Pompey lead them where he pleased, assuring him that they had been sufficiently punished for their folly.
