the benefit of its residents. It funded military expenditures (44% of the revenue), colonial government's expenses (41%), and sent some money to the Spanish colony of Fernando Po (12%). The Spaniards, representing 8% of the island's population, were appropriating over 90% of the island's wealth. In addition, the Cuban-born population still had no political rights and no representation in Parliament. Objections to these conditions sparked the first serious independence movement, especially in the eastern part of the island. Revolutionary conspiracy In July 1867, the "Revolutionary Committee of Bayamo" was founded under the leadership of Cuba's wealthiest plantation owner, Francisco Vicente Aguilera. The conspiracy rapidly spread to Oriente's larger towns, most of all Manzanillo, where Carlos Manuel de Céspedes became the main protagonist of the uprising in 1868. Originally from Bayamo, Céspedes owned an estate and sugar mill known as La Demajagua. The Spanish, aware of Céspedes’ anti-colonial intransigence, tried to force him into submission by imprisoning his son Oscar. Céspedes refused to negotiate and Oscar was executed. History Uprising Céspedes and his followers had planned the uprising to begin 14 October, but it had to be moved up four days earlier, because the Spaniards had discovered their plan of revolt. In the early morning of 10 October, Céspedes issued the cry of independence, the "10th of October Manifesto" at La Demajagua, which signaled the start of an all-out military uprising against Spanish rule in Cuba. Céspedes freed his slaves and asked them to join the struggle. 10 October is now commemorated in Cuba as a national holiday under the name Grito de Yara ("Cry of Yara"). During the first few days, the uprising almost failed: Céspedes intended to occupy the nearby town of Yara on 11 October. In spite of this initial setback, the uprising of Yara was supported in various regions of the Oriente province, and the independence movement continued to spread throughout the eastern region of Cuba. On 13 October, the rebels took eight towns in the province that favoured the insurgency and acquisition of arms. By October's end, the insurrection had enlisted some 12,000 volunteers. Military responses That same month, Máximo Gómez taught the Cuban forces what would be their most lethal tactic: the machete charge. He was a former cavalry officer for the Spanish Army in the Dominican Republic. Forces were taught to combine use of firearms with machetes, for a double attack against the Spanish.
