Lands were scarce in Apulia at the time and the roving Guiscard could not expect any grant from Drogo, then reigning, for Humphrey had just received his own county of Lavello. Guiscard soon joined Prince Pandulf IV of Capua in his ceaseless wars with Prince Guaimar IV of Salerno (1048). The next year, however, Guiscard left Pandulf, according to Amatus of Montecassino because Pandulf reneged on a promise of a castle and his daughter's hand. Guiscard returned to his brother Drogo and asked to be granted a fief. Drogo, who had just finished campaigning in Calabria, gave Guiscard command of the fortress of Scribla. Dissatisfied with this position, Guiscard moved to the castle of San Marco Argentano (after which he later named the first Norman castle in Sicily, at the site of ancient Aluntium).
