The rising was fixed for the 8th, but on the 7th Charles Albert had changed his mind and wished to delay the movement. Again Santa Rosa and his friends urged him to act with them, but without telling him on which day the insurrection was to break out.

There was, indeed, no time to be lost; for suspicions had already arisen of the designs of the Liberals, and arrests were being made. On March 10th, therefore, Count Palma seized on the citadel of Alessandria and proclaimed the Spanish Constitution. Almost at the same time Captain Ferrero occupied the little town of San Salvario and unfurled the Italian flag in the church. Students and soldiers readily joined the insurgents, and both King and Ministers in Turin were seized with panic. Orders came from the Powers at Laybach that Victor Emmanuel should march to Alessandria, and Balbo called on all loyal soldiers to return to Asti.

But Santa Rosa was as firm in his purposes as the Royalists were undecided. The Spanish Constitution was proclaimed in the fortress of Turin, and the soldiers, who were sent to attack the people, fled after a few shots; Charles Albert represented to the King the wishes of the people; and on the night of March 14th, Victor Emmanuel abdicated in favour of his brother Charles Felix, appointing Charles Albert Regent in Turin. On the following day Charles Albert, in his capacity of Regent, swore to accept the Spanish Constitution.

But it was soon apparent that one vigorous man could not make a revolution successful, when he had to depend on a nobility many of whom were servile admirers of Austria, and on a Regent who "would and would not." Men were appointed to posts in the new administration who had no claim to their office except their rank. The leaders in Alessandria suspected the leaders in Turin; while the hopes of persuading Charles Albert to declare war on Austria grew fainter and fainter.

In the meantime, the new King, Charles Felix, was residing in Modena, under the protection of the Grand Duke. Francis IV. of Modena had shown himself the most distinctly tyrannical of all the princes of Italy; while his extravagance and indifference to the welfare of his people had startled even Metternich. His relationship to the House of Savoy had led him to sympathise at first with Victor Emmanuel in his irritation at the arrogance of Austria; but that very same relationship now led him to hope that he might succeed to the throne instead of Charles Albert, if the latter offended the ruling Powers. He therefore readily supported Charles Felix in his protest against the proceedings of the new Regent.

Charles Felix, on his side, was a man of more rugged and narrow spirit than Victor Emmanuel, and had none of the sense of national dignity which occasionally interfered with the despotic inclinations of his brother. When, therefore, he issued from Modena a denunciation of the new Government, he did not scruple to add that, if order were not soon restored, his august allies would come to his rescue. In the same letter he ordered Charles Albert to go to Novara and place himself under the orders of Della Torre. "I shall see by this," said Charles Felix, "if you are still a Prince of the House of Savoy, or if you have ceased to be so." Charles Albert concealed this letter from his Ministers; and, after a few days of hesitation, fled secretly to Novara.

The feeble officials of Turin would have at once deserted the cause; but, in defiance of their opinion, Santa Rosa published a proclamation declaring that the King was a prisoner in the hands of the enemy, and that he, as Minister of Charles Albert, called on them to stand by the Constitution and declare war on Austria. One or two of the generals fled to Della Torre, at Novara; but at the same time the Genoese rose on behalf of the Spanish Constitution. Della Torre sent orders to Santa Rosa, in the name of the King, to resign his authority. Santa Rosa refused to recognize the King while he remained in a foreign country, and despatched a force against Novara.

But, in the meantime, the news came that General Pepe had in vain tried to rally his forces in defence of the Neapolitan Constitution; that his bands had been dispersed at the first attack of the Austrians; and that the Austrians, having crushed out the freedom of Naples, were marching northwards. The Russian Ambassador thereupon entreated the Junta to modify the Spanish Constitution. Some of the Ministers were inclined to consent; but Santa Rosa knew that to lose the Spanish Constitution was to lose the watchword of the Revolution; and no doubt he felt the indignity of yielding to a foreign ambassador. He therefore refused this proposal, and once more despatched forces against Della Torre, who was now preparing to march on Turin.

Colonel Regis, the leader of the Constitutional forces, succeeded in reaching Novara before Della Torre had begun his advance. The armies met outside the town; but in the middle of the battle the news arrived that the Austrians had crossed the Ticino and were marching into the country. Regis and Ferrero fought gallantly; but the double forces against them were too strong; and though they once or twice repelled the Austrian attack, the want of discipline of the Piedmontese soldiers, combined with the superior force of the enemy, led to a crushing defeat. Santa Rosa, finding it impossible to defend Turin, retreated first to Alessandria and then to Genoa; but the men on whom he relied had lost courage and hope; and he and such of his friends as were fortunate enough to reach Genoa were soon obliged to leave it again and to fly from Italy, most of them to fight in foreign countries for the liberty which they had lost at home.

The reaction set in with the greatest fury. In Piedmont the system of espionage was resumed with double force. The University was closed. Under the influence of favouritism, and in the absence of any free expression of public opinion, corruption of tribunals revived, and the Jesuits, who had lost power during the Liberal interregnum, speedily recovered it. In Naples, the Austrians, after recommending mildness to Ferdinand, yielded to his demands for the right to punish; and the sense of his dishonourable position seems to have called out in him a savagery which he had not previously shown; while the presence of the Austrian troops irritated the country into a state of intermittent insurrection.
