The Mexican government demanded the removal of General Almonte and his associates from the camp of the allies, and in this demand the British and Spanish representatives concurred. A somewhat stormy conference was held between the commissioners of the allied powers at Orizaba, April 2, 1862, at which the French agents virtually said that they did not regard the convention of London or the preliminaries of Soledad as binding upon them. Specifically then the two causes of the rupture were (1) the persistency of the French commissioners in opposing the removal of the Mexican exiles, and (2) their refusal to take part in the conferences which had been arranged by the convention of Soledad to be held with the Juarez government at Orizaba, April 15, 1862. The British government heartily approved of the action of its agent, Sir Charles Wyke, in breaking up the conference and putting an end to the joint action of the three powers.[215] The policy of Spain was completely in accord with that of England. The French government was not satisfied with the convention of Soledad, but did not dispute its validity, and declared that if the negotiations should be broken off, its provisions in regard to the withdrawal of the troops from their vantage ground must be observed. The French government further assumed that, when negotiations with the Mexican government should be broken off, the allied forces would proceed to act jointly under the convention of London.[216] The British and Spanish governments, however, having become convinced of the duplicity of the French government in the matter, terminated the London convention without further discussion and ordered the immediate withdrawal of their forces and agents from Mexican territory. The government of Louis Napoleon, thus left to its own devices by the withdrawal of Great Britain and Spain, and by the helpless condition, for the time being, to which the war of secession had reduced the government of the United States, greatly reinforced its Mexican expedition and placed General Forey in command. Soon after the withdrawal of the British and Spanish contingents, General Almonte instituted a government in the territory occupied by the French and assumed the title of "Supreme Chief of the Nation," but it soon became evident, as Mr. Dayton expressed it, that instead of the emperor having availed himself of the services of General Almonte, Almonte had availed himself of the services of the emperor. Accordingly, shortly after General Forey assumed command, he issued an order dissolving the ministry of Almonte, depriving him of his title and limiting him thereafter "in the most exact manner to the instructions of the emperor, which are to proceed as far as possible, with other Mexican generals placed under the protection of our flag, to the organization of the Mexican army."
