Minister of Public Works After Cavour's death king Victor Emmanuel II gave the task to form a new government firstly to
Bettino Ricasoli and then to
Urbano Rattazzi; Rattazzi was the leader of the Left and created a cabinet composed by both political groups. On 3 March 1862, Depretis was appointed
Minister of Public Works, and served as intermediary in arranging with Garibaldi. However, in August 1862 the
Royal Italian Army defeated Garibaldi's army of volunteers, who were marching from
Sicily towards
Rome, with the intent of annexing it into the
Kingdom of Italy. In the battle, which took place a few kilometers from
Gambarie, Garibaldi was wounded and taken as prisoner. Rattazzi's policy of repression towards Garibaldi at
Aspromonte, caused lot of public protests and the Prime Minister was forced to resign in September 1862. Moreover, Francesco Crispi accused Depretis of having mounted the Mazzinian riots in
Sarnico in May 1862 to discredit Garibaldi. After the fall of the Rattazzi government, therefore, it was easy to predict the end of Depretis's political career, when Crispi was elected leader of the Left. Depretis remained on the sidelines during the 8th legislature (1863–65), but he regularly participated in the parliamentary works, intervening regarding the laws for administrative unification and declaring himself hostile to
regionalism. He was particularly active during the
electoral campaign of 1865 and at the beginning of the 9th legislature he was elected vice president of the
Chamber of Deputies.
Minister of Navy In 1866, in anticipation of the war with the
Austrian Empire, after the signing of the
Italo-Prussian alliance, Ricasoli was appointed prime minister by the king to replace General
Alfonso Ferrero La Marmora, who would lead the Italian troops during the war. The king wanted to established a government of "national conciliation" that included members both form the
Right and the Left. in 1866 On 20 June, Depretis was appointed
Minister of the Navy, After the Italian defeat in the
Battle of Custoza, Depretis insisted with admiral
Carlo Persano on the attack against the island of
Lissa, as a revenge for Custoza. But he also refused to give to admiral Persano detailed orders about the expedition in the
Adriatic Sea against the fleet led by
Wilhelm von Tegetthoff. However the Italian
Regia Marina ("Royal Navy") was soundly defeated. To quell the public outcry after the two defeats, Depretis called for process Persano, who was judged by the
Italian Senate, condemned for incompetence in 1867 and cashiered from duty. However the war ended in an Austrian defeat, with Austria conceding the region of
Venetia to Italy. Italy's acquisition of this wealthy and populous territory represented a major step in the process of Italian unification. On 17 February 1867, Depretis resigned as minister of the Navy. His tenure as minister was quite controversial; his apologists contend, however, that, as an inexperienced civilian, he could not have made sudden changes in naval arrangements without disorganizing the fleet, and that in view of the impending hostilities he was obliged to accept the dispositions of his predecessors. ==Leader of the Left==
