Some hint of an approaching outbreak seems to have reached the ears of the King or his Ministers; for in August two artillery officers and some other citizens were arrested in Palermo. "But," says La Farina, the Sicilian historian, "nothing could be discovered, since the Sicilians knew better than any nation how to stand firm in preserving silence in all tortures: an ancient virtue not yet destroyed by modern corruption."

The miserable local jealousies which had hindered the former struggles for liberty had for a time disappeared; but there was still in this conspiracy, as in every other, the natural division between the impetuous and the prudent, between the party of speedy action and the party of delay. And while the fiery spirits of Messina and Calabria were eager for an immediate rising, the citizens of the two capitals, Palermo and Naples, were in favour of slower action. At Messina, therefore, the first outbreak took place. On September 1 some officers met at an inn in that town to celebrate the promotion of one of their generals by a dinner. The conspirators seized this opportunity for an outbreak, and surrounded the inn as if from mere curiosity; but when sufficient numbers had gathered they suddenly unfurled the tricolour flag and raised the cries of "Viva Italia!" "Viva Pio Nono!" "Viva la Costituzione!" The officers at last became alarmed, and, rushing out, summoned the soldiers and ordered them to fire. They hesitated to obey, and listened to the appeal of the conspirators, who urged their common cause and the duty of Neapolitans and Sicilians to stand together against their common oppressor. Discipline, however, proved stronger than patriotism; the soldiers fired, and several Sicilians fell, amongst them Giovanni Grillo, the youth who had played the part of the birds in stopping the ears of the King's statues.

The insurgents retreated; but a shoemaker named Sciva, who was at work near the scene of action, left his shop and rushed forward to rally them; and a priest named Kriny also fought gallantly in their ranks. The movement, however, had been too hastily organized; the insurgents were either forced to fly or were arrested on the spot, and Sciva, the shoemaker, was condemned to death. The authorities, indeed, hoped to persuade him to save his life by betraying his friends; but he refused, even on the scaffold, to accept a pardon on such terms, and died bravely. Kriny, as a priest, had his sentence commuted from death to imprisonment. Grillo died of his wounds.

Desperate efforts were made by the Government to obtain information as to the details of this conspiracy. Three hundred ducats were offered to anyone who would kill the chief conspirators; a thousand to anyone who would arrest them. But, though the leaders of the insurrection were hidden in the houses of very poor men, no one could be found to betray them, even for the sake of so large a reward. Even where the Government had made sure of their prey, it sometimes slipped through their hands. One of the insurgents was brought wounded to a house, and his hiding-place was discovered and surrounded by soldiers; but, by a false alarm, the guards were frightened away and the wounded man conveyed elsewhere. The owner of the second place of refuge was arrested, but the fugitive was again enabled to escape. His wound brought on fever, and he remained hidden for fifteen days without food, sucking the end of a sheet for nourishment; he was then so exhausted that his friends thought him dead and carried him to a church; but he revived, and was at last shipped to Marseilles, where he recovered.

A people so vigorous and determined were obviously not far from freedom. The heroism of the Sicilians had strengthened the courage of the Neapolitans; and on Christmas Day the latter rose to the cry of "Evviva Palermo!" This demonstration, however, was only the forerunner of the Revolution; for it was still from Sicily that the first successful action was to come. So little did the Sicilians care to conceal their intentions that a pamphlet was circulated fixing January 12 as the day for the actual rising. The police, thinking that they would be able easily to suppress the movement, began to make arrests; but their efforts were in vain.

La Farina, who afterwards became a member of the Sicilian Assembly, gives the following account of the rising:—

"On the night that preceded the 12th January, 1848, the streets of Palermo were silent and deserted; but in the houses the citizens were wakeful, agitated by fears and hopes. At the dawning of the new day the soldiers were in arms in fortified places and in their own quarters; some battalions of infantry and gensdarmes occupied the public places of the prefecture of police and of the royal palace, where the General De Majo, the Lieutenant of the King, General Vial, Commandant of the Piazza, and other royal officers, were assembled in council. The cannons of Castellamare were drawn out for a festival, for it was the birthday of Ferdinand II., and the roads were extraordinarily full of people; all were waiting for the conspirators to appear, for the sign to be given, for the first cry to break out, when Buscerni, a bold and ready youth, weary of delay, raised on high a musket that he had held concealed, and cried resolutely, 'To arms! To arms!' Then Pasquale Miloro came out armed into the street of the Centorinari; the abbot Ragona and the priest Venuti exhorted the people to rise in the name of God. There ran up to them, in arms, the advocate Tacona, Giuseppe Oddo, Prince Grammonte, Baron Bivona, Lo Cascio, Pasquale Bruno, Francesco Ciaccio, Giancinto Carini, Amodei, Enea, and a few others. Giuseppe La Masa bound to a stick a white pocket-handkerchief, a red one, and a green ribbon, and waved the three Italian colours. Santa Astorina went about distributing tricolour ribbons and cockades."

"At the sight of the arms, and of the small number of those who bore them, the crowd grew thin and dispersed; the shops were closed, and the few eager men remained alone. A few of the unarmed remained with them to divide the honour and perils of the attack; and among these, distinguished by the loftiness of their mind and remarkable probity, were Vincenzo Errante and the Baron Casimiro Pisani. They were not disheartened; they stood firm and bold in their resolve; the bells of the Church of Orsola sounded an alarm, those of the Convent of the Gangia answered them; the Revolution had become irrevocable. Small bands were forming themselves here and there. They had neither rules, orders, nor plans; they did not barricade the streets; they did not make trenches, as is usual in other cities; they did not make head in any one position; troops of children preceded them, dancing and singing; they drew near to the troops, watched their motions and acts, and returned to warn the insurgents even while the blood was dropping from the blows that they had received. One band of the insurgents put to flight a military patrol in the street of the Albergava; others had the same fortune in the Raffadale street, at the church of San Gaetano, near the gate of St. Antonino, in the street of Calderari, and in other places. Thus passed the whole day; two of the insurgents, among whom was L'Amodei, were dead, and ten soldiers; the wounded were more numerous. The insurgents withdrew within the Piazza of Fiera Vecchia, which since the morning had been the centre of the movements and the seat of a committee formed of the first insurgents. There were not more than fifty who had firearms; a company of infantry would have been sufficient to disperse them; but the soldiers remained immovable in the positions which they had taken up, because, remembering the year '20, they had determined not to advance into the populous quarters of the city. To this it is necessary to add that all the houses were lighted for the festival, and that the balconies of the windows were crowded with men, women, and children, who all clapped their hands and gave loud Vivas to Italy, the Sicilian Constitution, and Pio Nono; a spontaneous, unexpected, and universal agreement of the people which made the rulers lose their heads and the soldiers their hearts. In the night the insurgents were recruited from the country districts and the neighbouring communes. The first to arrive were sixty countrymen from Villabate; then others from Misilmeri and from other places. By the next day Fiera Vecchia contained about 300 men armed with guns, and as many more armed with scythes, billhooks, knives, spits, and those iron tools which the popular fury changes into arms. The fortress of Castellamare bombarded the city; the artillery of the royal palace was dragged along the Cassero; but the insurgents attacked, stormed, and destroyed the police commissariats and made themselves masters of the military hospital of San Francesco Saverio; the soldiers who remained prisoners were embraced as brothers, and provided with every accommodation which they needed."

Brilliant as these successes sound, the victory was not yet complete; and to diplomatists, at any rate, the result seemed still uncertain. The Consuls of Austria, France, and Sardinia tried to persuade the insurgents even now to yield, on condition of obtaining a pardon. An attack made by La Masa on the Royalist forces was repelled, and several of the revolutionary committees fled from Palermo. But many of the leaders stood firm, and Mariano Stabile declared that Sicily should recover her ancient liberties, and that Ferdinand and not the people was the rebel. At the same moment the bells sounded, and the Royalist artillery was brought to bear upon the city. For three hours the struggle lasted; but at the end of that time the Royalists were driven back. The Neapolitan soldiers, grown savage by their defeats, began to sack private houses and commit various acts of cruelty; and when the foreign Consuls went again to the Governor's palace to ask for mercy to the insurgents, they were fired upon.

In the meantime new insurgents were pouring in from the country districts, and the revolution was developing a government. Mariano Stabile was made secretary of the Governing Committee, and Ruggiero Settimo, an old man of seventy who had held office under the original Constitution of 1812, and who had helped to proclaim the Spanish Constitution in Sicily in 1820, was chosen President. Nor was the movement any longer confined to Sicily. The Neapolitans had risen in Salerno. The King, in a panic, had dismissed Del Caretto, the head of the police, from office; and General Ruberti, the Commandant of the fortress of St. Elmo, had told the King that he would not fire upon the people. A demonstration in favour of the Constitution of 1820 had taken place; and when the rain threatened to disperse the people, the umbrellas which were opened displayed the Italian colours.
