Victories of Metellus
Meanwhile Metellus fought with better fortune. In a sharp engagement at Italica (not far from Seville), which Hirtuleius had imprudently risked, and in which both generals fought hand to hand and Hirtuleius was wounded, Metellus defeated him and compelled him to evacuate the Roman territory proper, and to throw himself into Lusitania.
This victory permitted Metellus to unite with Pompeius. The two generals took up their winter-quarters in 678-79 at the Pyrenees, and in the next campaign in 679 they resolved to make a joint attack on the enemy in his position near Valentia. But while Metellus was advancing, Pompeius offered battle beforehand to the main army of the enemy, with a view to wipe out the stain of Lauro and to gain the expected laurels, if possible, alone. With joy Sertorius embraced the opportunity of fighting with Pompeius before Metellus arrived.
