In response to Sicard"s murder, the people of Salerno proclaimed Siconulf prince in opposition to Radelchis. At the time Radelchis was holding Siconulf prisoner in Taranto. A group of people from the cities of Salerno and Amalfi went there in disguise as Amalfian merchants and rescued Siconulf from prison, bringing him to Salerno.
lieutenant was Radelchis who first called in the aid of the Saracens against Siconulf in 841, though Siconulf soon retaliated by doing the same against his opponent.
The war lasted ten years, during which the Saracen ravages worsened and churches were despoiled. The major cities in the new principality were Taranto, Cassano Irpino, Paestum, Conza, Sarno, Cimitile (Nola), Capua, Teano, and Sora.
