When France made war against Mexico, we asked of France explanations of her objects and purposes. She answered, that it was a war for the redress of grievances; that she did not intend to permanently occupy or dominate in Mexico, and that she should leave to the people of Mexico a free choice of institutions of government. Under these circumstances the United States adopted, and they have since maintained entire neutrality between the belligerents, in harmony with the traditional policy in regard to foreign wars. The war has continued longer than was anticipated. At different stages of it France has, in her intercourse with us, renewed the explanations before mentioned. The French army has now captured Pueblo and the capital, while the Mexican government, with its principal forces, is understood to have retired to San Luis Potosi, and a provisional government has been instituted under French auspices in the city of Mexico, which being supported by arms, divides the actual dominion of the country with the Mexican government, also maintained by armed power. That provisional government has neither made nor sought to make any communication to the government of the United States, nor has it been in any way recognized by this government. France has made no communication to the United States concerning the provisional government which has been established in Mexico, nor has she announced any actual or intended departure from the policy in regard to that country which her before-mentioned explanations have authorized us to expect her to pursue.[219]
The probable acceptance of the crown by Maximilian was, however, the subject of frequent communications between the governments of France and the United States. In the course of a somewhat familiar conversation with M. Drouyn de Lhuys, the French minister of state, in August, 1863, Mr. Dayton expressed the fear that in quitting Mexico France might leave a puppet behind her. De Lhuys replied: "No; the strings would be too long to work."
The chances of Maximilian's success in Mexico had been from the first deliberately calculated on the basis of the probable success of the Southern Confederacy; and, therefore, the cause of the Juarez government and the cause of the Union were considered the same. The active sympathy of the Unionists with the Mexican republic made it difficult for the administration to maintain neutrality. This difficulty was further enhanced by the doubt entertained in the United States as to the intentions of France. In this connection Mr. Seward wrote to Mr. Dayton, September 21, 1863, as follows:
The President thinks it desirable that you should seek an opportunity to mention these facts to Mr. Drouyn de Lhuys, and to suggest to him that the interests of the United States, and, as it seems to us, the interests of France herself, require that a solution of the present complications in Mexico be made, as early as may be convenient, upon the basis of the unity and independence of Mexico.[220]
In reply, the French minister declared that the question of the establishment of Maximilian on the Mexican throne was to be decided by a majority vote of the entire nation; that the dangers of the government of the archduke would come principally from the United States, and the sooner the United States showed itself satisfied, and manifested a willingness to enter into peaceful relations with that government, the sooner would France be ready to leave Mexico and the new government to take care of itself, which France would, in any event, do as soon as she with propriety could; but that she would not lead or tempt the archduke into difficulty, and then desert him before his government was settled. He said that the early acknowledgment of that government by the United States would tend to shorten, or perhaps to end, all the troublesome complications of France in that country; that they would thereupon quit Mexico.[221]
To this communication, Mr. Seward replied that the French government had not been left uninformed of the opinion of the United States that the permanent establishment of a foreign and monarchical government in Mexico would be found neither easy nor desirable; that the United States could not anticipate the action of the Mexican people; and that the United States still regarded Mexico as the scene of a war which had not yet ended in the subversion of the government long existing there, with which the United States remained in the relation of peace and friendship.[222]
Before formally accepting the crown, the archduke visited England with a view to securing a promise of recognition for his new position. He was, of course, to pass through Paris, and in view of his approaching visit, Mr. Dayton asked for instructions as to his conduct on the occasion. Mr. Seward replied, February 27, 1864:
I have taken the President's direction upon the question. If the Archduke Maximilian appears in Paris only in his character as an imperial prince of the house of Hapsburg, you will be expected to be neither demonstrative nor reserved in your deportment toward him. If he appears there with any assumption of political authority or title in Mexico, you will entirely refrain from intercourse with him. Should your proceeding be a subject of inquiry or remark, you will be at liberty, in the exercise of your own discretion, to say that this government, in view of its rights and duties in the present conjuncture of its affairs, has prescribed fixed rules to be observed, not only by this department, but by its representatives in foreign countries. We acknowledge revolutions only by direction of the President, upon full and mature consideration.[223]
The archduke visited London in company with his father-in-law, Leopold of Belgium. The British government declined to act on the subject at that juncture, "but gave them reason to hope that, so soon as the action in Mexico would appear to justify it, they would acknowledge him."[224] Spain and Belgium were ready to follow in the wake of France.
About the time of this visit of Maximilian to England, Mr. McDougall, of California, introduced in the Senate a resolution declaring "that the movements of the government of France, and the threatened movement of an emperor, improvised by the Emperor of France, demand by this republic, if insisted upon, war." This resolution was not carried, but some days later, on the 4th of April, 1864, the House of Representatives passed by a unanimous vote a resolution declaring its opposition to the recognition of a monarchy in Mexico. Mr. Seward, fearing a rupture with France on this account, took pains to inform the government of that country, through Mr. Dayton, that this action of the House was in no way binding on the executive, even if concurred in by the Senate.
