The next movement worthy of note came in 1849, if we omit the quarrel, in 1837, between General Tacon and his subordinate, General Lorenzo, and the alleged proposal of the slaves in the neighborhood of Matanzas to rise and slaughter all the whites. Neither of these quite belongs in the revolutionary class. In 1847, a conspiracy was organized in the vicinity of Cienfuegos. Its leader was General Narciso Lopez. The movement was discovered, and some of the participants were imprisoned. Lopez escaped to the United States where he associated himself with a group of Cuban exiles, and opened correspondence with sympathizers in the island. They were joined by a considerable number of adventurous Americans, inspired by a variety of motives. The declared purpose of the enterprise was independence as the alternative of reform in Spanish laws. An expedition was organized, but the plans became known and President Taylor, on August 11, 1849, issued a proclamation in which he declared that "an enterprise to invade the territories of a friendly nation, set on foot and prosecuted within the limits of the United States, is in the highest degree criminal." He therefore warned all citizens of the United States who might participate in such an enterprise that they would be subject to heavy penalties, and would forfeit the protection of their country. He also called on "every officer of this Government, civil or military, to use all efforts in his power to arrest for trial and punishment every such offender against the laws." The party was captured as it was leaving New York. The best evidence of the time is to the effect that there was in Cuba neither demand for nor support of such a movement, but Lopez and his associates, many of them Americans, persisted. A second expedition was arranged, and a party of more than six hundred men, many of them American citizens, assembled on the island of Contoy, off the Yucatan coast, and on May 19, 1850, landed at Cardenas. But there was no uprising on the part of the people. The Spanish authorities, informed of the expedition, sent ships by sea and troops by land. After a sharp skirmish, the invaders fled for their lives. Lopez and those who escaped with him succeeded in reaching Key West. He went to Savannah, where he was arrested but promptly liberated in response to public clamor. But even this did not satisfy the enthusiastic liberator of a people who did not want to be liberated in that way. He tried again in the following year. On August 3, 1851, he sailed from near New Orleans, on the steamer _Pampero_, in command of a force of about four hundred, largely composed of young Americans who had been lured into the enterprise by assurance of thrilling adventure and large pay. They landed near Bahia Honda, about fifty miles west of Havana. Here, again, the Cubans refused to rise and join the invaders. Here, again, they encountered the Spanish forces by whom they were beaten and routed.
