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]
