Matilda of Tuscany
Matilda of Tuscany and her husband managed to turn Henry's heir, Conrad, against him in the spring or summer of 1093. Henry had Conrad captured, but he escaped to Milan. According to Bernold of Constance, Henry tried to commit suicide after his son's rebellion, though Bernold probably invented this story to make a comparison between Henry and King Saul. Conrad's disloyalty aroused Henry's suspicion of his relatives, and he put his wife under strict supervision, allegedly for her infidelity. Four Lombard towns (Milan, Cremona, Lodi and Piacenza) made an alliance with Matilda of Tuscany. Henry fled to Verona whose margrave, Henry of Eppenstein, and Eppenstein's brother, Patriarch Udalric of Aquileia, were his last supporters in Italy. Henry's authority remained limited to north-eastern Italy, and Matilda and Welf I's troops prevented his return to Germany.
