It was in the early spring of 1869 that the first proposals were made to the Prince; our information as to this is very defective, but it seems that they were at once rejected. Benedetti's suspicions were, however, aroused. He heard that a Spanish diplomatist, who had formerly been Ambassador at Berlin, had again visited the city and had had two interviews with Bismarck. He feared that perhaps he had some mission with regard to the Hohenzollern candidature, and, in accordance with instructions from his Government, enquired first of Thiele and, after a visit to Paris, saw Bismarck himself. The Count was quite ready to discuss the matter; with great frankness he explained all the reasons why, if the throne were offered to the Prince, the King would doubtless advise him not to accept it. Benedetti was still suspicious, but for the time the matter dropped. From what happened later, though we have no proof, we must, I think, share his suspicion that Bismarck was already considering the proposal and was prepared to lend it his support.
In September of the same year, the affair began to advance. Prim sent Salazar, a Spanish gentleman, to Germany with a semi-official commission to invite the Prince to become a candidate, and gave him a letter to a German acquaintance who would procure him an introduction to the Prince. This German acquaintance was no other than Herr von Werther, Prussian Ambassador at Vienna. If we remember the very strict discipline which Bismarck maintained in the Diplomatic Service we must feel convinced that Werther was acting according to instructions.[9] He brought the envoy to the Prince of Hohenzollern; the very greatest caution was taken to preserve secrecy; the Spaniard did not go directly to the castle of Weinburg, but left the train at another station, waited in the town till it was dark, and only approached the castle when hidden from observation by night and a thick mist. He first of all asked Prince Charles himself to accept the throne, and when he refused, offered it to Prince Leopold, who also, though he did not refuse point-blank, left no doubt that he was disinclined to the proposal; he could only accept, he said, if the Spanish Government procured the assent of the Emperor Napoleon and the King of Prussia. Notwithstanding the reluctance of the family to take the proffered dignity, Herr von Werther (and we must look on him as Bismarck's agent[[9]]) a fortnight later travelled from Munich in order to press on the Prince of Roumania that he should use his influence not to allow the House of Hohenzollern to refuse the throne. For the time, however, the subject seems to have dropped. A few months later, for the third time, the offer was repeated, and now Bismarck uses the whole of his influence in its favour. At the end of February, Salazar came on an official mission to Berlin; he had three letters, one to the King, one to Bismarck, one to the Prince. The King refused to receive him; Prince Leopold did not waver in his refusal and was supported by his father; their attitude was that they should not consider the matter seriously unless higher reasons of State required it. With Prince Bismarck, however, the envoy was more successful; he had several interviews with the Minister, and then left the city in order that suspicions might not be aroused or the attention of the French Government directed to the negotiations. Bismarck pleaded with great warmth for the acceptance of the offer; in a memoir to the King, he dwelt on the great importance which the summons of a Hohenzollern prince to the Spanish throne would have for Germany; it would be politically invaluable to have a friendly land in the rear of France; it would be of the greatest economic advantage for Germany and Spain if this thoroughly monarchical country developed its resources under a king of German descent. In consequence of this, a conference was held at Berlin, at which there were present, besides the King, the Crown Prince, Prince Carl Anton, and Prince Leopold, Bismarck, Roon, Moltke, Schleinitz, Thiele, and Delbrück. By summoning the advice of these men, the matter was taken out of the range of a private and family matter; it is true that it was not officially brought before the Prussian Ministry, but those consulted were the men by whom the policy of the State was directed. The unanimous decision of the councillors was for acceptance on the ground that it was the fulfilment of a patriotic duty to Prussia. The Crown Prince saw great difficulties in the way, and warned his cousin, if he accepted, not to rely on Prussian help in the future, even if, for the attainment of a definite end, the Prussian Government furthered the project for the moment. The King did not agree with his Ministers; he had many serious objections, and refused to give any definite order to the Prince that he should accept the offer; he left the final decision to him. He eventually refused.
Bismarck, however, was not to be beaten; he insisted that the Hohenzollerns should not let the matter drop; and, as he could not persuade the King to use his authority, acted directly upon the family with such success that Prince Carl Anton telegraphed to his third son, Frederick, to ask if he would not accept instead of his brother. Bismarck had now declared that the acceptance by one of the Princes was a political necessity; this he said repeatedly and with the greatest emphasis. At the same time, he despatched a Prussian officer of the general staff and his private secretary, Lothar Bucher, to Spain in order that they might study the situation. It was important that as far as possible the official representative of Prussia should have no share in the arrangement of this matter.
Prince Frederick came to Berlin, but, like his brother, he refused, unless the King gave a command. At the end of April, the negotiations seemed again to have broken down. Bismarck, who was in ill health, left Berlin for Varzin, where he remained for six weeks.
We are, however, not surprised, since we know that Bismarck's interest was so strongly engaged, that he was able after all to carry the matter through. He seems to have persuaded Prince Carl Anton; he then wrote to Prim telling him not to despair; the candidature was an excellent thing which was not to be lost sight of; he must, however, negotiate not with the Prussian Government, but with the Prince himself. When he wrote this he knew that he had at last succeeded in breaking down the reluctance of the Prince, and that the King, though he still was unwilling to undertake any responsibility, would not refuse his consent if the Prince voluntarily accepted. Prince Leopold was influenced not only by his interest in the Spanish race, but also by a letter from Bismarck, in which he said that he ought to put aside all scruples and accept in the interests of Prussia. The envoys had also returned from Spain and brought back a favourable report; they received an extraordinarily hearty welcome; we may perhaps suspect with the King that they had allowed their report to receive too rosy a colour; no doubt, however, they were acting in accordance with what they knew were the wishes of the man who had sent them out. In the beginning of June the decision was made; Prince Leopold wrote to the King that he accepted the crown which had been offered to him, since he thereby hoped to do a great service to his Fatherland. King William immediately answered that he approved of the decision.
Bismarck then at last was successful. A few days later Don Salazar again travelled to Germany; this time he brought a formal offer, which was formally-accepted. The Cortes were then in session; it was arranged that they should remain at Madrid till his return; the election would then be at once completed, for a majority was assured. The secrecy had been strictly maintained; there were rumours indeed, but no one knew of all the secret interviews; men might suspect, but they could not prove that it was an intrigue of Bismarck. If the election had once been made the solemn act of the whole nation, Napoleon would have been confronted with a fait accompli. To have objected would have been most injurious; he would have had to do, not with Prussia, which apparently was not concerned, but with the Spanish nation. The feeling of France would not allow him to acquiesce in the election, but it would have deeply offended the dignity and pride of Spain had he claimed that the King who had been formally accepted should, at his demand, be rejected. He could scarcely have done so without bringing about a war; a war with Spain would have crippled French resources and diverted their attention from Prussia; even if a war did not ensue, permanent ill feeling would be created. It is not difficult to understand the motives by which Bismarck had been influenced. At the last moment the plan failed. A cipher telegram from Berlin was misinterpreted in Madrid; and in consequence the Cortes, instead of remaining in session, were prorogued till the autumn. All had depended on the election being carried out before the secret was disclosed; a delay of some weeks must take place, and some indiscreet words of Salazar disclosed the truth. General Prim had no course left him but to send to the French Ambassador, to give him official information as to what had been done and try to calm his uneasiness.
What were Bismarck's motives in this affair? It is improbable that he intended to use it as a means of bringing about a war with France. He could not possibly have foreseen the very remarkable series of events which were to follow, and but for them a war arising out of this would have been very unwise, for German public opinion and the sympathy of all the neutral Powers would have been opposed to Prussia, had it appeared that the Government was disturbing the peace of Europe simply in order to put a Prussian prince on the throne of Spain contrary to the wishes of France. He could not ignore German public opinion now as he had done in old days; he did not want to conquer South Germany, he wished to attract it. It seems much more probable that he had no very clear conception of the results which would follow; he did not wish to lose what might be the means of gaining an ally to Germany and weakening France. It would be quite invaluable if, supposing there were to be war (arising from this or other causes), Spain could be persuaded to join in the attack on France and act the part which Italy had played in 1866. What he probably hoped for more than anything else was that France would declare war against Spain; then Napoleon would waste his strength in a new Mexico; he would no longer be a danger to Germany, and whether Germany joined in the war or not, she would gain a free hand. by the preoccupation of France. If none of these events happened, it would be an advantage that some commercial gain might be secured for Germany.
On the whole, the affair is not one which shews his strongest points as a diplomatist; it was too subtle and too hazardous.
The news aroused the sleeping jealousy of Prussia among the French people; the suspicion and irritation of the Government was extreme, and this feeling was not ill-founded. They assumed that the whole matter was an intrigue of Bismarck's, though, owing to the caution with which the negotiations had been conducted, they had no proofs. They might argue that a Prussian prince could not accept such an offer without the permission of his sovereign, and they had a great cause of complaint that this permission had been given without any communication with Napoleon, whom the matter so nearly concerned. The arrangement itself was not alone the cause of alarm. The secrecy with which it had been surrounded was interpreted as a sign of malevolence.
Of course they must interfere to prevent the election being completed. Where, however, were they to address themselves? With a just instinct they directed their remonstrance, not to Madrid, but to Berlin; they would thereby appear not to be interfering with the independence of the Spaniards, but to be acting in self-defence against the insidious advance of German power.
