Never, in the opinion of both Villiers and of Wylde, had the constitutional cause presented so gloomy an appearance as in the closing months of the year 1838. The Queen’s generals had suffered heavy defeats in the open field and Espartero had been compelled to abandon his operations against Morella, Cabrera’s stronghold. Political rather than strategical considerations appear to have dictated the conduct of the campaign. Fearing that Espartero might grow too powerful, the Cabinet was suspected of having deliberately neglected to reinforce him, whilst keeping his rival and enemy, Narvaez, who commanded the army of reserve, liberally supplied with troops.[408] In England no minister would have ventured to propose that any further assistance, either in men or money, should be sent to the Christinos, who had greatly fallen in the public estimation. The commercial classes were indignant that, notwithstanding the help which the Queen’s cause had received, prohibitory duties upon British manufactures should still be maintained. The newspapers were full of the complaints of the soldiers of the legion, who had returned home with their claims upon the Spanish treasury unsatisfied. The policy of encouraging these men to enter Isabella’s services was now universally condemned. The good name of the British army had, it was feared, suffered from their misconduct at the seat of war. The action of the government, in conferring a knighthood of the Bath upon De Lacy Evans, in no way lessened this impression.[409]

But, in the early spring of 1839, the news arrived of strange proceedings in the Pretender’s camp. Maroto, the Carlist commander-in-chief, having discovered the existence of a plot to overthrow him, had caused four general officers to be shot at Estella, on February 18. Don Carlos, who was in secret sympathy with the conspirators, thereupon deprived Maroto of his command and proclaimed him a traitor. That officer, however, knew that he could count upon the devotion of his men, and he, accordingly, boldly marched upon Tolosa, where the wretched Don Carlos was residing, and compelled him both to revoke his decree and to dismiss his Apostolical advisers. But Maroto, although he had on this occasion triumphed so completely, was well aware that at any moment his troops might turn against him, and that his life depended upon a speedy termination of the war. Notwithstanding that Turner’s attempts to incite the Navarrese chieftains to rebellion had failed, and that Muñagorri’s insurrection had practically collapsed, the longing for peace had not diminished among the men of Biscay and Navarre. After the executions at Estella and his coercion of Don Carlos, Maroto had no alternative but to adopt the popular cry of “Paz y Fueros.” Instead of an obscure lawyer, the commander-in-chief of the Pretender’s armies was now at the head of the counter-insurrection against him.[410]

Whilst the Carlist general had thus the strongest possible inducement for coming to terms with the Christinos, other circumstances had arisen which contributed to the undoing of the Pretender. Espartero was now all powerful and in a position to carry on the war, untrammelled by the intrigues of the Court and of the Cabinet.[411] In France Molé had fallen and Soult was once more at the head of the government. The Marshal, in the previous year, had represented Louis Philippe at the coronation of Queen Victoria, and had returned to France delighted with the welcome accorded him in London by all classes of the population.[412] He was, consequently, very well disposed towards England and far more inclined than any of his predecessors to act up to the spirit of the Quadruple Treaty. No sooner was he in power than orders were sent to the French ships, stationed off the north coast of Spain, identical in every respect with those with which the British admiral was furnished. At the same time, the authorities upon the frontier were strictly enjoined both to prevent supplies from reaching the Carlists and to embarrass the movements of the Pretender’s armies by all means in their power.[413]

Maroto’s first definite proposals of peace seem to have been made to Lord John Hay, either on July 27 or 28. It is probable, however, that for some time past he had been in more or less direct communication with Espartero, with whom he had served in South America. The negotiations, once formally begun, continued for the next month. Espartero, however, wisely refused to grant any suspension of hostilities, and, whilst showing himself always ready to listen to reasonable proposals, pushed on his military operations vigorously. The question which proved the most difficult of settlement was that of the Fueros, which the Biscayans and Navarrese stipulated must be maintained in their integrity. The Queen Regent’s government, in accordance with Palmerston’s advice, was only prepared to make such concessions with regard to them, as might be compatible with the representative form of government which Spain had adopted. The recognition of the sovereignty of Isabella, the regency of Christina and the Constitution of 1837 were also insisted upon. Colonel Wylde was present at most of the conferences which took place. He was authorized to explain to any Carlist officers, with whom he might be enabled to converse, that, “although it would not be consistent with the dignity of the Spanish nation that Her Majesty’s government should guarantee any arrangement, they could rely upon the good offices of the British government should, at any time, the government of Madrid depart from its agreements.”[414]

Espartero’s skilful conduct of the negotiations, combined with the personal reasons which made it imperative for Maroto to conclude a peace, triumphed at last over all obstacles. On August 29, a convention was signed at Vergara settling the points in dispute and providing for the capitulation of Maroto’s army. Two days later the 21 battalions specified in the treaty marched into the camp of the Christinos and, having been harangued by Espartero, proceeded to fraternize joyfully with the Queen’s troops.[415] Don Carlos, nevertheless, was still able to command the fidelity of a certain number of his regiments. But Espartero, the moment the capitulation of Maroto’s people had been completed, pressed these remnants of the insurgent army with the utmost vigour. Their resistance was soon overcome, and, on September 15, 1839, Don Carlos with a few thousand followers was driven across the frontier. On reaching French territory they were at once disarmed, the Pretender and the members of his family being conveyed to Bourges, where they were detained under strict supervision. It was not without difficulty that Louis Philippe’s ministers had obtained his consent to that measure of precaution.

Although Don Carlos had abandoned the struggle, Cabrera in the Maestrargo, and the no less bloodthirsty Count of España in Catalonia, still carried on the war with ruthless barbarity. In November, however, España, having incurred the displeasure of the Carlist junta, was removed from his command. His body shortly afterwards was taken out of the river Segre “tied neck and heels.”[416] Without doubt he had been murdered by the escort which was supposed to convey him to a place of confinement. But it was not till the month of July, 1840, that Espartero succeeded in driving Cabrera and his lieutenant, Balmaceda, into France and in breaking up the last of the Carlist bands.

Spain, however, was not destined to enjoy the blessings of internal peace and tranquillity. Christina had never really accepted the principles of constitutional government, and most of the leading Moderados shared her dislike to democratic institutions. With the object, accordingly, of rendering nugatory certain of the Liberal provisions of the constitution the party, during the session of 1840, introduced a bill abolishing the election of municipal officers, and establishing a system under which they were, in the future, to be appointed by the central government. The Spaniards, however, have always been tenacious of their municipal rights and privileges, and the proposed law was, in consequence, greatly disliked by the people. The Queen Regent and her Moderado advisers would have cared little for popular opposition, provided always that they could have obtained the support of one man. “Espartero,” in the words of Mr. Southern, the British chargé d’affaires, “now formed one of the bodies of the State.”[417] The general who had succeeded in terminating the civil war was, for the time being, the idol of the nation.

Espartero, however, was deaf to the blandishments of the Moderados, and publicly declared that he regarded the municipal bill as unconstitutional.[418] Christina, nevertheless, was confident that he would never resist her personal appeal. She had always recognized the importance of winning his gratitude. For his services he had been created Count of Luchana, Duke de la Victoria, and a Spanish grandee of the first class. After his capture of Cabrera’s stronghold, in 1840, she had conferred upon him the additional title of Duke of Morella. When the municipal law was under discussion in the Chamber, she suddenly announced her intention of proceeding to Caldes, near Barcelona, with Isabella, who was alleged to have been ordered sea bathing. But the significance of her journey to the coast lay in the fact that it would enable her to meet, and to confer with, Espartero, who was directing the final operations in Cabrera’s country.[419] Her interview with the all-powerful general took place, in due course, at Lerida, but it disappointed her expectations. Espartero advised her strongly to refuse her assent to the bill, although it had been passed by both Chambers. It was notorious that the Moderado majority had been obtained by means of corruption and intimidation at the elections of the previous year, and that it in no way represented the will of the nation. Christina wavered. At one time she decided to follow the counsels of Espartero, at another she resolved to adhere firmly to her Moderado policy. Meanwhile, the country was growing dangerously excited, and Barcelona was the scene of serious rioting. Christina, in consequence, decided to move the Court to Valencia, where O’Donnell, on whom she could depend, commanded the troops. Upon her arrival, she boldly announced that she purposed to commission Modesto Cortazar, a former minister of Joseph Bonaparte, to form an ultra-Moderado Cabinet. At the news, the country rose, juntas sprang into existence in the principal towns, and a provisional government was established at Madrid.[420]

Villiers was no longer at Madrid. On succeeding to the earldom of Clarendon, he had returned home, where a seat in the Cabinet had been found for him. When he learnt of the critical state of affairs in Spain, Palmerston at once directed Mr. Aston, Clarendon’s successor, to seek out Christina, wherever she might be, and to attempt to convince her of the imprudence of the course upon which she had embarked.[421] But before he could reach Valencia, she had abandoned the struggle, and had sullenly surrendered the direction of affairs to Espartero. She fully intended, she informed Aston at his first audience, to resign the regency, and no words of his could turn her from her resolution.[422] It was not alone the desire to avoid the disagreeable necessity of having to accept a Progressista government which had prompted her to arrive at this decision. Gonzalez Bravo and the Radicals possessed the proof of her marriage to Nuñoz, the guardsman, by whom she had already had several children. In order to retain the regency, and especially the emoluments appertaining to it, she had allowed it to be generally believed that she was the mistress of the handsome and low-born soldier. But now that her secret had been betrayed, her marriage might be adduced at any moment as a reason for declaring her incompetent to hold the post of Regent.[423] Only by a voluntary abdication could she escape from this further humiliation. Accordingly, on October 12, 1840, she signed the act whereby she resigned the regency, and left it to the Cortes to appoint her successor. A few days later she parted from her daughters, and set out for France. On May 18 of the following year, Espartero was duly elected Regent, whilst Argüelles, a veteran Progressista, was nominated guardian of Queen Isabella.

Christina’s abdication passed almost unnoticed outside Spain. The quarrel between the Sultan and the Pasha had broken out afresh, and England and France were upon the verge of war.
