Passage: By summer 1076, through piracy and raids Gisulf II of Salerno incited the Normans to destroy him; that season, under Richard of Capua and Robert Guiscard the Normans united to besiege Salerno. Although Gisulf ordered his citizens to store two years' worth of food, he confiscated enough of it to starve his subjects. On 13 December 1076, the city submitted; the prince and his retainers retreated to the citadel, which fell in May 1077. Although Gisulf's lands and relics were confiscated, he remained at liberty. The Principality of Salerno had already been reduced to little more than the capital city and its environs by previous wars with William of the Principate, Roger of Sicily and Robert Guiscard. However, the city was the most important in southern Italy and its capture was essential to the creation of a kingdom fifty years later.

Question: What happened to Gisulf's property after retreating?
Gisulf's lands and relics were confiscated
