The royalist party returned in triumph from Cadiz, having replaced Ferdinand VII. on his throne. In that country, where moderation either in politics or religion is unknown, the power had fallen into the hands of Don Saez, the king's confessor; and the object of Russia being always to exercise a powerful influence in the south of Europe, in order to counterbalance that of England, Count Pozzo received orders to repair to Madrid and use all his endeavours to push M. Hirujo into the ministry, who was a man of moderate views, and consequently inclined to favour the Russian interests. A perfect understanding on this head existed between the Russian minister and M. de Villèle. M. de Hirujo, forerunner of M. Zéa, gained the ascendant at Madrid, and people could reckon upon the government of Ferdinand being conducted with some degree of order and regularity. Pozzo di Borgo then returned to Paris; he was on intimate terms with MM. Pasquier and Molé, friends of the Duc de Richelieu, and disapproved highly of the folly of the royalist party, who tormented France every year with fresh laws, still more remarkable for their silliness and want of importance than for their unpopular tendency; but the ambassador had now hardly any influence upon the government; it was almost entirely confined to the opposition formed in the diplomatic circles and in good society, which before long extended to the conduct of the sovereign. Although he approved of the law regarding the conversion of the rentes,[24] he had no hesitation in giving utterance to his opinion concerning the extreme unpopularity the measure would naturally be attended with. "The King of France," said he, "wishes to become the richest sovereign in Europe; but I greatly fear this measure will lead to some unfortunate catastrophe. People do not play with impunity with the pot-au-feu of the citizens." And the event shewed his opinion to have been well founded.

At this period the Russian ambassador lost his protector, I may almost say his friend. Alexander died on his journey into the Crimea, a pilgrimage enveloped in mystery,[25] and which was immediately followed by the revolutionary movement in St. Petersburg. Some officers were desirous of throwing the government into the hands of the old Russian nobility, always ready to enter into any measure calculated to restore the predominance of the Muscovite aristocracy, which was a sort of republic formed of the great vassals of the crown. Would the Emperor Nicholas repose the same confidence in Pozzo di Borgo that his predecessor had done? He had not like Alexander a sort of brotherhood in arms and affairs with his ambassador, but as Count Nesselrode remained at the head of affairs, he retained his situation and presented his renewed credentials to Charles X. at the time when the storms of the opposition assumed every where a menacing aspect. Two years afterwards the ministry of M. de Villèle was at an end, and the king formed a fresh administration, at the head of which he intended placing M. de Martignac and M. de la Ferronays. The latter was at that time ambassador at St. Petersburg, and enjoyed the confidence of the Emperor Nicholas, who was therefore likely to be satisfied with his appointment to the ministry, and Pozzo di Borgo considered it necessary to support him with all his power; for the interests of Russia had at that time assumed so complicated a form, that the concurrence of France was a matter of the greatest importance to her.

Russia had deeply offended the Porte by signing the treaty of the month of June 1827, which established the independence of Greece; and the Mussulmans, proud of their ancient glory, had been still further irritated by the battle of Navarino. The occupation of Moldavia and Wallachia had given rise to fresh dissensions, which ended by the Russian ambassador's quitting Constantinople. Every thing was thus progressing towards a war likely to involve Russia in considerable danger, especially if England were to take part with the Sultan: the Emperor Nicholas was determined to pass the Balkan, for he found it necessary to employ the superstitious and turbulent disposition of the old Russian nobility in active military operations, to prevent its bursting out in revolutionary attempts.

Under these circumstances Count Nesselrode commissioned Pozzo di Borgo to sound the French cabinet as to the conditions they would require,—not for an armed alliance, but simply to observe a friendly neutrality during the oriental war. Count Pozzo proposed that France should keep up a force of 100, or 150,000, to act as a check upon Austria, and augment her armaments, so as to restrain England; he also hinted that should any important advantages result to Russia from the events of the campaign, the frontiers of France might possibly be reconsidered and the natural boundary of the Rhine granted to her without expense, by arranging an indemnity for Prussia and Holland; and that indeed it was not impossible the Morea might be given her as a compensatory measure, with the same rights as those enjoyed by England over the republic of the seven islands. What a magnificent portion this would have been for France!

The first operations of the campaign were not attended with success: there were sanguinary sieges and doubtful battles. During this time Count Pozzo exhibited the utmost activity in Paris, where the checks sustained by the Russians were the general subject of conversation, and General Lamarque had even published a series of articles to prove that the destruction of the army was inevitable. General Pozzo entered much into society, and at every fresh disaster or difficulty he strove to remove the fears they excited as to the consequences of the war: "Wait, have patience," repeated he incessantly, "and then you will see." The best understanding existed between him and M. de la Ferronays, who exerted himself to calm the minds which England took equal pains to disturb.

The following year the Russian armies were more fortunate, having advanced upon Constantinople, and the position of the ambassador became less difficult; but to counterbalance this advantage, the ministerial revolution took place in the month of August, which placed Prince Polignac, and consequently the English system of precedents and opinions, at the head of affairs. Pozzo de Borgo was much annoyed at this change; the cabinet of St. Petersburg entered into an explanation on the subject with M. de Mortemart, and in proportion as the French ministry advanced in the adventurous path of coups d'état, Count Pozzo multiplied his despatches to his government to warn them of an impending catastrophe. The information he gave on this subject was so positive, that the Emperor spoke to M. de Mortemart, telling him he was well aware some foolish steps were about to be taken in Paris. "The king of France," added he, "is at liberty to act as he pleases in his kingdom, but if evil comes of it, so much the worse for him. Give him warning that he will not be supported, and that Europe will not engage in a quarrel on his account."

The Russian ambassador only became acquainted with the ordonnances of July the evening before they were promulgated; he had neither been informed confidentially, nor had he received any official intimation; only a few days before the event he said in a conference with Polignac, "Prince, I do not wish to inquire into your secrets, I do not ask you what you are about, only take precautions not to compromise Europe;" and then Prince Polignac replied with his habitual smile, so expressive of perfect security, "All we ask is, that Europe will not compromise us." At these words the ambassador turned his back upon him. When the fatal ordonnances appeared the next day in the Moniteur, Pozzo di Borgo expressed great dissatisfaction and alarm at seeing the utter carelessness of the government in the midst of so much difficulty and danger, and the total absence of any military force or precaution. "How," said he, "are there no troops? The bridges are not occupied! Have no military precautions been taken?" "Every thing is quiet," replied they, "nobody stirs." "Every thing quiet!" repeated the ambassador warmly, "yes, every thing will probably be quiet to-day, but to-morrow we shall have firing in the streets, and the next day who knows what may happen? I shall be obliged to ask for my passports."

Here was the commencement of another series of events. It is necessary to judge the conduct of the ambassador during the latter days of the government which was about to expire, and the commencement of that which succeeded to it.

The events of July were characterised by so much agitation and importance, that the corps diplomatique must have found itself placed in an embarrassing position: Charles X. had quitted St. Cloud and sought refuge at Rambouillet, and a municipal commission had restored order in the midst of the insurrection. If Prince Polignac had possessed the slightest political forethought, he would have notified to the corps diplomatique that the king proposed removing his menaced government to such and such a part of the kingdom; this resolution would have served as an official order to all the ambassadors, to accompany the sovereign who had received their credentials, and by whom they were officially accredited, and their presence at St. Cloud would have been a sort of protest against the events then taking place at Paris; it might also have facilitated the negotiation between the royal party and the Hôtel de Ville, for the provisional government would have been afraid of committing itself with Europe, and being exposed to a general war. But with the utter carelessness he displayed in the whole business, Prince Polignac, minister for foreign affairs, made no official communication to the corps diplomatique, but treated every thing with a degree of levity quite in keeping with his predestinarian character.
