The next serious complication arose out of the Ten Years’ War, in Cuba, in 1868, to which reference is made in a chapter on Cuba’s revolutions.  Spain’s leaders seemed quite incapable of grasping the Cuban situation, of seeing it in its proper light.  It is more than probable that, even then, the Cubans would have remained loyal if the Spanish authorities had paid attention to their just and reasonable demands.  As stated by Mr. Pepper, in his Tomorrow in Cuba, “The machete and the torch then gained what peaceful agitation had not been able to achieve.”  The demands of the Cubans are thus stated by Senor Cabrera, in his Cuba and the Cubans:  “A constitutional system in place of the autocracy of the Captain-General, freedom of the press, the right of petition, cessation of the exclusion of Cubans from public office, unrestricted industrial liberty, abolition of restrictions on the transfer of landed property, the right of assembly and of association, representation in the Cortes, and local self-government,” all reasonable and just demands from every point of view of modern civilization.  Spain refused all, and on October 10, 1868, an actual revolution began, the first in the history of the island to be properly classed as a revolution.  The United States soon became concerned and involved.  In his message to Congress on December 6, 1869, President Grant said:  “For more than a year, a valuable province of Spain, and a near neighbor of ours, in whom all our people cannot but feel a deep interest, has been struggling for independence and freedom.  The people and the Government of the United States entertain the same warm feelings and sympathies for the people of Cuba in their pending struggle that they have manifested throughout the previous struggles between Spain and her former colonies (Mexico, Central America and South America) in behalf of the latter.  But the contest has at no time assumed the conditions which amount to a war in the sense of international law, or which would show the existence of a de facto political organization of the insurgents sufficient to justify a recognition of belligerency.”  On June 13, 1870, President Grant sent a special message to Congress, in which he reviewed the Cuban situation.  Another reference appears in his message of December 5, 1870.  In his message of December 4, 1871, he stated that “it is to be regretted that the disturbed condition of the island of Cuba continues to be a source of annoyance and anxiety.  The existence of a protracted struggle in such close proximity to our own territory, without apparent prospect of an early termination, cannot be other than an object of concern to a people who, while abstaining from interference in the affairs of other powers, naturally desire to see every other country in the undisturbed enjoyment of peace, liberty, and the blessings of free institutions.”  In the message of December 2, 1872, he said:  “It is with regret that I have again to announce
