The fact that this happened simultaneously with Sardinia's submission to the will of Europe was a wonderful piece of luck, which, as Massimo d'Azeglio said, could happen only once in a century. When the Austrian Government took the irrevocable step, it did not know yet that the whole onus of breaking the peace would fall upon it. Nor, it must be remembered, did it know the test of the treaty between France and Sardinia, and in view of the French Emperor's recent conduct it may well have become convinced that no treaty at all existed. Hence it is probable that Austria flattered herself that she would only have to deal with weak Sardinia.

The Chamber of Deputies was convoked on April 23 to confer plenary powers on the king. Many deputies were so overcome that they wept. Just as the President of the Chamber announced the vote, a scrap of paper was handed to Cavour, on which were written the words in pencil: "They are here; I have seen them." It was from a person whom he had instructed to inform him instantly when the bearers of the Austrian Ultimatum arrived. They were come; angels of light could not have been more welcome! Cavour went hastily out, while the House broke into deafening cries of "Long live the king!" He said to the friend who brought the message, "I am leaving the last sitting of the last Piedmontese Chamber." The next would represent the kingdom of Italy.

The Sardinian army to be placed on a peace-footing, the volunteers to be dismissed, an answer of "Yes" or "No" required within three days—these were the terms of the Ultimatum. If the answer were not fully satisfactory His Majesty would resort to force. Cavour replied that Piedmont had given its adhesion to the proposals made by England with the approval of France, Prussia and Russia, and had nothing more to say. No one who saw the statesman's radiant face would have guessed that less than a week before he had passed through so frightful a mental crisis. He took leave of Baron von Kellersberg with graceful courtesy, and then, turning to those present, he said, "We have made history; now let us go to dinner."

The French Ambassador at Vienna notified to Count Buol that his sovereign would consider the crossing of the frontier by the Austrian troops equivalent to a declaration of war.

Lord Malmesbury was so favourably impressed by Sardinia's docility and so furious with the Austrian coup de tête that he became in those days quite ardently Italian, which he assured Massimo d'Azeglio was his natural state of mind; and such it may have been, since cabinet ministers are constantly employed in upholding, especially in foreign affairs, what they most dislike. He hoped to stop the runaway Austrian steed by proposing mediation in lieu of a Congress; but the result was only to delay the outbreak of the war for a week, much to the disadvantage of the Austrians, as it gave the French time to arrive and the Piedmontese to flood the country by means of the canals of irrigation, thus preventing a dash at Turin, probably the best chance for Austria. Baron von Kellersberg and his companion, during their brief visit, had done nothing but pity "this fine town so soon to be given over to the horrors of war." Their solicitude proved superfluous.

For the present the statesman's task was ended. He had procured for his country a favourable opportunity for entering upon an inevitable struggle. When Napoleon said to Cavour on landing at Genoa, "Your plans are being realised," he was unconsciously forestalling the verdict of posterity. The reason that he was standing there was because Cavour had so willed it. In spite of the Emperor's fits of Italian sympathy and the various circumstances which impelled him towards helping Italy, he would not have taken the final resolution had not some one saved him the trouble by taking it for him. As a French student of history has lately said, in 1859, as in 1849, there was a Hamlet in the case; but Paris, not Turin, was his abode. Napoleon needed and perhaps desired to be precipitated. Look at it how we may, it must be allowed that he was doing a very grave thing: he was embarking on a war of no palpable necessity against the sentiment, as the Empress wrote to Count Arese, of his own country. A stronger man than he might have hesitated.

The natural discernment of the Italian masses enlightened them as to the magnitude of Cavour's part in the play, even in the hour when the interest seemed transferred to the battlefield, and when an emperor and a king moved among them as liberators. At Milan, after the victory of Magenta had opened its gates, the most permanent enthusiasm gathered round the short, stout, undistinguished figure in plain clothes and spectacles—the one decidedly prosaic appearance in the pomp of war and the glitter of royal state. Victor Emmanuel said good-humouredly that when driving with his great subject, he felt just like the tenor who leads the prima donna forward to receive applause.

Success followed success, and this to the popular imagination is the all-and-all of war. Milan was freed, though the battle of Magenta was not unlike a drawn one; Lombardy was won, though the fight for the heights of Solferino could hardly have resulted as it did if the Austrians had not blundered into keeping a large part of their forces inactive. Would the same fortune be with the allies to the end? Cavour does not appear to have asked the question. He watched the war with no misgivings. It was to him a supreme satisfaction that the Sardinian army, which he had worked so hard to prepare, did Italy credit. He took a personal pride in the romantic exploits of the volunteers, though for political reasons he carefully concealed that he had been the first to think of placing them in the field. He made an indefatigable minister of war (having taken the office when La Marmora went to the front). The work was heavy; the problem of finding even bread enough for the allied armies was not a simple one. On one occasion the French Commissariat asked for a hundred thousand rations to make sure of receiving fifty thousand; the officer in charge was surprised to see one hundred and twenty thousand punctually arrive on the day named. Cavour's thoughts were not, however, only with the troops in Lombardy. The whole country was in a ferment, and instead of accelerating events the question now was to keep pace with them.

When Ferdinand II died, and a young king, the son of a princess of the House of Savoy, ascended the throne, Cavour invited him to join in the war with Austria. The invitation has been blamed as insincere and unpatriotic, but the best Neapolitans seconded it. Poerio said he was willing to go back to prison if King Francis would send his army to help Piedmont. Faithful to his primary object of expelling the Austrians, Cavour would have taken for an ally any one who had troops to give. Moreover, an alliance between Naples and Sardinia meant the final shelving of a scheme which had caused him anxiety, off and on, for many years: that of a Muratist restoration. Though he had always recognised that, were it accepted by the Neapolitans themselves, it would be impossible for him to oppose it, he understood that to place a Murat on the throne of Naples would be to move in the old vicious circle by substituting one foreign influence for another. There is no doubt that the idea was attractive to Napoleon. One of his first cares after he became Emperor had been to find an accomplished Neapolitan tutor for the young sons of Prince Murat. About the time of the Paris Congress emissaries were actively working on behalf of the French pretender in the kingdom of Naples. The propaganda was in abeyance during the war, because Russia made it a condition of her neutrality that the king of Naples should be let alone, but the simple fact that Napoleon had undertaken to liberate Italy was a splendid advertisement of the claims of his cousin. These considerations tended to make Cavour hold out his hand to the young Bourbon king. There is much evidence to show that the first impulse of Francis was to take it, but the counter influences around him were too strong. When he refused, he sealed his own doom, though the time for the crisis was not yet come.

In Central Italy the crisis came at once. This had been foreseen by Cavour all along. At Plombières he made no secret of his expectation that the defeat of the Austrians would entail the immediate union of Parma, Modena, and Romagna, with Piedmont. Napoleon did not then seem to object. To him Cavour did not speak of Tuscany, but he expected that there, too, the actual government would be overthrown; what he doubted was what would happen after. Many well-informed persons thought that the Grand Duke, who would have maintained the constitution of 1848 but for the threats of Austria, would seize the first opportunity of restoring it. Fortunately Leopold II. looked beneath the surface: he saw that an Austrian prince in Italy was henceforth an anachronism. The indignities which he suffered when his Italian patriotism—possibly quite sincere—caused him to be disowned by his relations were not forgotten. He had no heart for a bold stroke, and the exhortations of the English Government to remain neutral were hardly needed. If he wavered, it was only for a moment; nor did he care to place his son in the false position he declined for himself. The Grand Duke left Florence, openly, at two o'clock on April 27, 1859, carrying with him the personal good wishes of all. The chief boulder in the path of Italian unity was gone, but for reasons internal and external much would have to be done before Tuscany became the corner-stone of New Italy. The Tuscans clung to their autonomy. Though Victor Emmanuel was invited to assume the protectorate, it was explained that this was only meant to last during the war. The French Emperor thought that there was an opening for a new kingdom of Etruria with Prince Napoleon at the head. All sorts of intrigues were set afoot by all the great powers except England to re-erect Tuscany as a dam to stem the flood of unity midway. Cavour was determined to defeat them. It was against his rule to discuss remote events. He once said to a novice in public life, "If you want to be a politician, for mercy's sake do not look more than a week ahead." Every time, however, that there arose a present chance of making another step towards unity, Cavour was eagerly impatient to profit by it. He now strove with all the energy he possessed to procure the immediate annexation of Tuscany to Piedmont. The object was good, but what he did not see was, that the slightest appearance of wishing to "rush" Tuscany would so offend the municipal pride and intellectual exclusiveness of the polished Tuscans, that the seeds would be laid of a powerful and, perhaps, fatal reaction. It was at this critical juncture that Baron Bettino Ricasoli began his year of autocracy. His programme was: neither fusions nor annexations, but union of the Italian peoples under the constitutional sceptre of Victor Emmanuel. It was Tuscany's business, he said, to make the new kingdom of Italy. He looked upon himself as providentially appointed to carry that business into effect. He was called Minister of the Interior, and he was, in fact, dictator. When any one tried to overawe him, his answer was that he had existed for twelve centuries. He had not wished for foreign help, and he was not afraid of foreign threats. He often disagreed with Cavour, and he was the only man who never gave in to him. When Ricasoli took office he and the republican baker, Dolfi, who was his invaluable auxiliary, were possibly the only two thorough-going unionists-at-all-costs in Tuscany; when he resigned it twelve months later there was not a partisan of autonomy left in the province. This was the work of the "Iron Baron."
