Political chaos and budgetary restraints in Italy likewise forced a slowdown in the rapid pace in which the Regia Marina had been arming itself with ironclad warships. In June 1862, Garibaldi, determined to conquer Rome and bring the Papal States into Italy, sailed from Genoa and landed at Palermo, intending to gather volunteers for the impending campaign to Rome. By the time he crossed over into mainland Italy, he had a force of some two thousand volunteers. After landing at Melito on 14 August, Garibaldi and his forces marched at once into the Calabrian mountains. Far from supporting this second expedition however, the Italian government strongly opposed Garibaldi's actions. General Enrico Cialdini dispatched a division of the regular army, under Colonel Emilio Pallavicini, against Garibaldi's volunteer corps. On 28 August the two forces met in the rugged Aspromonte. After roughly 10 minutes of fighting, there were 15 casualties, including Garibaldi himself who had been shot in the exchange of fire. The fighting ended quickly, as Garibaldi and his volunteers surrendered and were taken prisoner. The political backlash to the "battle" at Aspromonte and Garibaldi's subsequent arrest was enormous in Italy. December 1862, Rattazzi's government fell over the controversy, and Luigi Carlo Farini succeeded him as Prime Minister. Persano was thus removed as Italy's Minister of the Navy. When Marco Minghetti became Prime Minister in March 1863, General Efisio Cugia was chosen to replace Persano.
