Subsequently it came to light that Napoleon's surprising readiness in agreeing to the annexation of Central Italy in April had been due to a private arrangement between him and Cavour in the previous month. It was agreed between them in March that Savoy and Nice should be handed over to France as the price of her acquiescence. In the secret treaty of Plombières, Napoleon's reward for helping the Piedmontese, should the war leave Venice, Lombardy, and the Romagna in Victor Emmanuel's hands, had been fixed as the cession of these territories to France. But since Napoleon had withdrawn and made peace when, as yet, only Lombardy had been wrested from Austria, he had waived his claim upon Nice and Savoy at Villafranca, and claimed in exchange a contribution towards his expenses in the war. But the moment Piedmont proposed to annex Tuscany, the Romagna and the Duchies, he returned to his original claim. His action had two important results: one which immediately added to the complication of Italian politics, and one which affected the diplomatic relations of the Great Powers for the next eleven years. In Italy his demand made a lasting breach between Cavour and Garibaldi. The latter never forgave the cession of Nice, his native town, to France, and never could be convinced that the sacrifice of Italian territory was a necessary step towards uniting Italy. In his eyes the agreement with Napoleon had been a kind of treason on the part of Cavour. Among the European Powers, on the other hand, Napoleon's action created an impression, which was never effaced, that he was a predatory and treacherous power.

In England the news was received with the greatest indignation. Lord John was extremely angry, and practically threatened war. He, like Garibaldi, did not realize that Cavour was driven to the concession, nor that Napoleon was, in truth, compelled on his side to demand what he did. The following letter from Sir James Hudson, the English Minister at Turin--"uomo italianissimo," as Cavour called him--is particularly interesting, because, though addressed to Lady John, it reads as though it were also intended for the eyes of the Foreign Secretary, from whom indignation had temporarily concealed the truth that this sacrifice was the only compensation which would have induced Napoleon to look on quietly while the new kingdom of Italy was consolidating on his frontier. The last event Cavour desired was a war between the two Powers whose unanimity forced neutrality upon Austria. Napoleon on his side was practically obliged to demand Savoy and Nice as a barrier against Italy, and because the acquisition of territory alone could have prevented his subjects from feeling that they had lost their lives and money only to further the aims of Victor Emmanuel.

Sir James Hudson to Lady John Russell
TURIN, April 6, 1860
MY DEAR LADY JOHN,--I have seen Braico--Poerio brought him to me after I had offered my services to him in your name, and we have combined to dine together and to perform other feats, besides gastronomic ones, in order to cheer him whilst he resides in these (to a Parthenopean) Boeotian regions.
You mention in your letter the name of that scandal to royalty, Louis Napoleon. What can I say of him? Hypocrite and footpad combined. He came to carry out an "idea," and he prigs the silver spoons. "Take care of your pockets" ought to be the cry whenever he appears either personally or by deputy.
But do not, I beg of you, consider and confound either the King of Sardinia or Cavour as his accomplice. Think for a moment on the condition of Sardinia, who represents the nascent hope of Italy. Think of the evil that man meant--how he tried to trip up the heels of Tuscany, establish a precarious vicarial existence for the Romagna, and plots now at Naples. Not to have surrendered when he cried "stand and deliver" would have been to have risked all that was gained--would have given breathing time to Rome, reinforced and comforted Rome's partisans in the Romagna--have induced doubt, fear, and disunion throughout Italy. Judging by the experience of the last eight years, I must say I saw no means of avoiding the rocks ahead save by a sop to Cerberus. But do not lose confidence in the National party--Cavour or no Cavour, Victor Emmanuel or another, that party is determined to give Italy an Italian representation. I regret that the Nizzards (who have a keen eye to the value of building lots) are wrenched from us by a French filou; but I cannot forget that the Savoyards have constantly upheld the Pope, and have been firm and consistent in their detestation of Liberal Government in Sardinia. I am not speaking of the neutral parts, please remember.
Your most devoted servant,
JAMES HUDSON

Meanwhile the reign of Francis II of Naples and the Two Sicilies, who had succeeded Ferdinand, was proving if anything worse than his father's. Early in 1860 insurrections began to break out in Sicily, and on May 5th Garibaldi, on his own initiative, set sail from Genoa to help the rebels. "I go," he said, "a general without an army, to fight an army without a general." His success was extraordinarily rapid. At the end of May he had taken Palermo from 24,000 regular troops with his volunteers and some Sicilian help, thus making the dictatorship of Sicily, which he had declared on landing, a reality. It soon became known that he intended to recross to the mainland to free the people of Naples itself. Piedmont, of course, wished Garibaldi to succeed in this further undertaking. His cause was her cause. Though this action was entirely independent, his dictatorship had been avowed as a preliminary step to handing over the island to Victor Emmanuel. The King could not, therefore, oppose him nor prevent him re-embarking for Naples without separating himself from the cause of United Italy and making an enemy of almost every patriot in the country; but both he and Cavour were afraid either that Garibaldi might fail, in which case the union of Italy would have been postponed for many years, or that the pace at which changes were coming would lead France or Austria to interfere again.

France, of course, was most anxious to stop the further increase of the power of Piedmont, and therefore to check Garibaldi. Napoleon's idea of "United Italy" was a federation of separate States under the presidency of the Pope, who in his turn would be under the influence of France. He at once put pressure upon Cavour and Victor Emmanuel, compelling the latter to write to Garibaldi, telling him to stop in Sicily. Thus, in spite of her desire that Garibaldi should sail and succeed, Piedmont was compelled publicly to express disapproval of his intention. In England it was supposed that Cavour meant what he made the King say in his letter to Garibaldi, and in addition Palmerston, who was glad enough to see the old Governments of the little States tumbling to the ground, was rather alarmed at the prospect of a United Italy, which would also be a Mediterranean Power. Hitherto the honour of assisting Italy had belonged equally to him and to Lord John. Henceforward, however, Lord John, who had been brought up in the Fox tradition, and whose Italian sympathies had been fortified by his wife's enthusiasm, definitely took the lead in determining England's policy.

The aim of Cavour was to help the revolution as much as possible without making it obvious to Europe that he was doing so; but, like everybody else, Lord John had taken him at his word, and thought that the liberation of Italy might be retarded by Garibaldi's departure from Sicily for the mainland, till information reached him that in reality Piedmont was most anxious nothing should hinder Garibaldi's attack upon Naples. It reached him apparently in the following manner.

Cavour determined to appeal to the Russells personally through a secret agent. With this object Mr. Lacaita [afterwards Sir James Lacaita], who had been exiled from Naples for having helped Gladstone to write his famous letters upon the state of the Neapolitan prisons, which Lacaita knew from inside, was instructed to call upon Lord John in London and to tell him that in spite of her official declaration, Piedmont was desperately anxious that Garibaldi should drive the King of Naples from the throne; for Garibaldi's extraordinary success in Sicily had made his failure on the mainland far less likely, and Cavour was now certain that there was not much power of resistance left in the Neapolitan kingdom. Lacaita, though ill in bed, got up and went to deliver his message. He was told that Lord John was closeted with the French and Neapolitan ambassadors and could not see him. Lacaita guessed that Lord John was at that very moment talking over the means of preventing Garibaldi's expedition, and he immediately decided to ask for Lady John. When informed that she was seriously ill, he insisted upon being taken up into her bedroom, and adjured her for the love of Italy to get Lord John away from the ambassadors at once. A scribbled note begging her husband to come to her immediately brought him upstairs in some alarm. And there he learnt from Lacaita that Victor Emmanuel's letter of July 25th was a blind, that united Italy must be made now or never, and that he would never be forgiven if England stopped Garibaldi.
