October 10, 1868 marks the beginning of the Ten Years War in Cuba and is known as El Grito de Yara and is the Cuban equivalent to the War of Independence.
Ten Years War
On October 10, 1868, Carlos Manuel de C?spedes and a group of planters from the province of Oriente proclaimed the independence of Cuba in the historic Grito de Yara (Cry of Yara). Initially, there was no mention of the social question of slavery, but as the military campaign went on, it became clear that revolutionary success depended upon uniting all Cubans against Spanish rule. Men like Antonio Maceo, a mulatto from Santiago de Cuba, and M?ximo G?mez, a black Dominican exile, contributed to the revolutionary effort. The Cuban masses changed the character of the revolution into a democratic one that sponsored abolition. After a few military victories, the nationalist forces controlled half the island of Cuba. However, the Spanish government was not about to lose its prize possession in the Caribbean. Royalist forces launched a “total war” of destruction, inflicting terrible losses throughout the island.
Even though the Spanish armies were being supplied by the United States, the Cubans remained confident that people in the United States supported them morally and would eventually influence their government to render the Cubans much needed assistance. After ten years of bloodshed and the loss of an estimated 50,000 Cuban and 208,000 Spanish lives, the war was over. Under the 1878 Pact of Zanjon the crown agreed to enact reforms. However, the end of the war represented only the beginning of a truce between Spain and the Cuban revolutionaries. Men like Maceo and G?mez had become experts in guerrilla fighting and led the Cuban nationalists during the following years of the independence movement.
