Simeón Cuba Sarabia

Simeón Cuba Sarabia (15 January 1935 – 9 October 1967), also known as Willy, was a member of the Ñancahuazú guerrilla column led by Che Guevara in Bolivia. Born in the Cochabamba region of Bolivia, he became a leader among tin miners in Huanuni and served as the secretary of organization and secretary of militias of the local mine workers' union. He also carried out various social service activities for the benefit of the miners' families. Cuba Sarabia joined the Communist Party of Bolivia (PCB) but resigned from it in 1965 to become a member of the Bolivian Marxist–Leninist Party which favored armed struggle. When he urged that group to put its principles into practice, he was expelled from it along with Moisés Guevara. It was Moisés Guevara who brought him into Che Guevara's Ñancahuazú guerrilla group in March 1967.

Selected to be a member of the "center" unit which was led by Che Guevara himself, Willy came to be known as a disciplined and courageous combatant. Despite this, and perhaps as a result of his extremely reserved nature, Guevara developed suspicions about him and in his monthly summary for September 1967 wrote in his campaign diary that "The morale of the rest of the group has remained quite good, and I only have doubts about Willy, that he may take advantage of some havoc to try to escape by himself ... " His suspicions would soon prove to have been unfounded.

On 8 October 1967 when the guerrillas' final battle commenced in the Yuro Ravine, Willy was leading the "center" group as they tried to find a way to break out of the Army's encirclement. Willy was just at the point of clearing the steep wall of the ravine when Guevara, following some distance behind him, received a sudden blast of machine gun fire that wounded him in the leg. Willy turned around and went back down the cliff to where Guevara lay. He picked him up and carried him to a location out of the direct line of fire. However, the two guerrillas almost immediately found themselves surrounded by another group of rangers who opened fire against them; Guevara and Willy shot back at them until one of their bullets knocked Che's beret off his head and another disabled his M-2 carbine. Willy moved Guevara out of the line of fire again, then placed himself between his wounded leader and the rangers — who were now firing at them from a distance of less than ten yards — and began to return fire. In this exposed position, Willy was struck almost instantaneously by a hail of bullets and incapacitated. A group of rangers rushed forward, demanding their surrender. Seeing the soldiers approach Guevara, Willy confronted them and shouted, "This is Comandante Guevara. Show him respect!"
