exists as to the purport of the Aix la Chapelle letter; and that the policy therein declared by Mr. Buchanan and his associates, is identical with that which has uniformly been regarded and avowed as the policy of the United States in respect to the Island of Cuba. And a belief endeavored to be inculcated, that the policy of the Ostend conference was adopted in consultation or co-operation with the Red Republicans of Europe, is equally erroneous. This belief has originated in another supposition equally unfounded, that Mr. Soulé was in league with the leaders of the European revolutionary movement. The truth is, that fundamental differences existed between the policy of Mr. Soulé and Mazzini, Ledru Rollin, Kossuth, and Louis Blanc; and besides which fact it is well known that these revolutionary leaders themselves were agreed only upon one point, the necessity of revolution, and that they seldom speak to one another. The policy of the revolutionary party of Europe in reference to Cuba was this. They desired the United States to assist the Democratic party of Spain in creating a revolution at Madrid, which should dethrone the queen, and place the Democratic party in power, by the establishment of a republic, and then leave Cuba at her option to either remain a portion of the Spanish republic, or seek annexation to the United States. This concession to the United States was to be in return for material aid furnished in effecting the Spanish revolution. The revolution thus accomplished was intended to be the initiative of further revolutions on the Continent. The Pyrenees range of mountains which forms the boundary line between France and Spain are populated on either side by the most liberal men in either empire, the great mass of the inhabitants being Republican; and could a republic be established in Spain, the Pyrenees would not only furnish points from which to begin their revolutionary designs against France, but would form a barrier behind which they could defend themselves against any attack which Louis Napoleon might make. The revolution accomplished in France, Kossuth and Mazzini would have but little difficulty in overthrowing the power of Austria in Hungary and Italy. Such were the objects which the revolutionary leaders of Europe had in view in endeavoring to secure the influence of the United States Government in support of their policy.
