Insurrection in Sicily--The Austrians expelled from Milan and Venice--Charles Albert takes the Field--Withdrawal of the Pope and King of Naples--Piedmont defeated--The Retreat. On the 12th of January, the birthday of the King of the Two Sicilies, another insurrection broke out in Sicily; this time it was serious indeed. The City of the Vespers lit the torch which set Europe on fire. So began the year of revolution which was to see the kings of the earth flying, with or without umbrellas, and the principle of monarchy more shaken by the royal see-saw of submission and vengeance than ever it was by the block of Whitehall or the guillotine of the Place Louis XV. In Italy, the errors and follies of that year were not confined to princes and governments, but it will remain memorable as the time when the Italian nation, not a dreamer here or there, or a handful of heroic madmen, or an isolated city, but the nation as a whole, with an unanimity new in history, asserted its right and its resolve to exist. King Ferdinand sent 5000 soldiers to 'make a garden,' as he described it, of Palermo, if the offers sent at the same time failed to pacify the inhabitants. These offers were refused with the comment: 'Too late,' and the Palermitans prepared to resist to the death under the guidance of the veteran patriot Ruggiero Settimo, Prince of Fitalia. 'Separation,' they said, 'or our English Constitution of 1812.' Increased irritation was awakened by the discovery in the head office of the police at Palermo of a secret room full of skeletons, which were supposed to belong to persons privately murdered. The Neapolitans were compelled to withdraw with a loss of 3000 men, but before they went, the general in command let out 4000 convicts, who had been kept without food for forty-eight hours. The convicts, however, did not fulfil the intentions of their liberator, and did but little mischief. Not so the Neapolitan troops, who committed horrors on the peasantry as they retreated, which provoked acts of retaliation almost as barbarous. In a short time all Sicily was in its own hands except the citadel of Messina. It is not possible to follow the Sicilians in their long struggle for their autonomy. They stood out for some fourteen months. An English Blue-book is full of the interminable negotiations conducted by Lord Napier and the Earl of Minto in the hope of bringing the strife to an end. When the parliament summoned by the revolutionary government declared the downfall of the House of Bourbon, all the stray princes in Europe, including Louis Napoleon, were reviewed as candidates for the throne. The choice fell on the Duke of Genoa; it was well received in England, and the British men-of-war were immediately ordered to salute the Sicilian flag. But the Duke's reign never became a reality. After an heroic struggle, the islanders were subjugated in the spring of 1849.
