the pace of garibaldi's victories had worried cavour, who in early july sent to the provisional government a proposal of immediate annexation of sicily to piedmont. garibaldi, however, refused vehemently to allow such a move until the end of the war. cavour's envoy, giuseppe la farina, was arrested and expelled from the island. he was replaced by the more malleable agostino depretis, who gained garibaldi's trust and was appointed as pro-dictator.
