The Spanish party in Cuba, at this time, as we have seen, was known as the "Peninsulars," and it comprised a great majority of the office holders and wealthy planters and slave-holders. It was well organized throughout the Island for the assertion of political influence, and for the suppression of insurgent movements. Its central authority was in a wealthy club at Havana, called the "Casino Espagnol," and similar clubs on a more modest scale, existed in other cities and important towns throughout Cuba, and from these, and under their control, there arose a body known as the "Volunteers." This was ostensibly a military organization to whose battalions all white men in the Island were eligible, but as a matter of fact, membership in the Volunteers was substantially confined to conservatives, loyalists and Spanish sympathizers. The Volunteers, except in a few special cases, did not go into the field, but left the actual fighting with insurgents to be done by regular Spanish troops. They gave their own attention chiefly to the overawing of the inhabitants of the cities and towns, and to restraining them from joining the revolutions. They also acted as spies, discovering and reporting to the Spanish Government the doings of Cuban patriots. The leaders of the organization formed a "Council of Colonels," meeting at the Casino Espagnol, and forming a sort of _imperium in imperio_. During the progress of the Ten Years' War, however, the Volunteers were organized and placed under the command of General Lersuno, and thereafter exerted a much more militant power than ever before. They were not under the direct orders of the Captain-General, but enjoyed an independent authority, and yet they were presently entrusted with the garrisoning of forts and cities, so that the regular Spanish troops could go into the field. They exercised far more military, naval and civil authority than the Captain-General and other royal officials. They actually compelled the retirement of General Dulce from the Captain-Generalship because they regarded him as too kindly disposed toward the Cubans. They similarly drove Caballero de Rodas from office, and they gave Valmaseda and Ceballos, who followed, to understand that the success of their administration depended upon their compliance with the demands and policies of the Volunteers. It was due to their opposition that the so-called Moret law, which provided for the gradual abolition of slavery in Cuba, remained a dead letter, and was not even published in the Island for several years after the outside world had supposed it to be in force. The Volunteers were also responsible for the numerous cases of violence against the patriot party, the most flagrant of which was the execution of eight Cuban students of the University of Havana.
