The war between Venice and Croatia was renewed in Summer 1018, when Krešimir launched a campaign against the Dalmatian cities in an attempt to retake the lost territories. The cities requested Otto Orseolo for help, who intervened on the eastern coast of the Adriatic Sea and managed to successfully repel these incursions from Croatia. According to surviving legal documents, the islands Krk and Rab, that were previously under Croatian control, restated their allegiance to Venice and promised to pay an annual tribute.
