Eulogio Cantillo (September 13, 1911, Cuba - September 9, 1978, Miami, Florida, U.S.) was a general in the pre-revolutionary Cuban army. General Cantillo served as Chief of the Joint Staff during the dictatorship of Fulgencio Batista. Cantillo did not participate in the military coup that brought Batista to power. During the Cuban Revolution, he led Cuban soldiers in the fight against Fidel Castro's 26th of July Movement. After the Cuban Revolution, He was tried by the revolutionary tribunals and sentenced to 15 years in prison. He was released before serving his entire sentence sometime in the sixties, and went into exile in Miami where he died in 1978.
General Eulogio Cantillo was Chief of the Army Aviation Corps before he was appointed as Head of the Joint Chiefs. In the Cuban revolution, Cantillo led an offensive that unfolded in the summer of 1958 under the name Operation Verano, which had the goal of destroying the guerrillas of Fidel Castro that had been causing several army losses since the spring of 1957. At the time of the revolution, Cuba had a regular army of 24 battalions, and a total strength of 20,000 soldiers. For Operation Verano, Cantillo had 14 battalions with about 12,000 soldiers. Most of the soldiers were young recruits.
Cantillo surrounded the mountain range of the Sierra Maestra, and set up roadblocks to prevent supplies from getting to the guerrillas, and attacked from the north to drive the guerrillas down to the south coast. On the south coast he could make better use of air support, and artillery, than in the jungles of Sierra Maestra where guerrillas were impossible to hit. The offensive failed, largely because Cantillo's soldiers fought in unfamiliar terrain (forests and jungles of the Sierra Maestra) and because much of the army was demoralized and unmotivated. They were trained to fight against regular troops and not against 26 July Movement guerrillas that struck with tremendous firepower in one second, and disappeared into the jungle in the seconds after.
On August 8, 1958 Cantillo signed a secret armistice with the 26th of July movement, and thus the entire Verano offensive was over. Reasons to truce is unclear. Some argue that Cantillo sympathized with the guerrillas, while others claim that Cantillo still believed that Castro had over 2000 well-trained and well disciplined guerrillas. Therefore, he needed the truce to regroup his own forces so he could better counter the guerrillas. Fidel Castro however, used this time to create a counteroffensive, known as the Cauto campaign.
He was left as head of the Cuban Military after Batista fled to the Dominican Republic in the early hours of January 1, 1959. He was later arrested by the revolutionary government, and put on trial. He was sentenced to 15 years in prison, but was released before he served his full sentence, and left Cuba to become a Cuban exile in Miami. While in Miami, he joined anti-Castro groups, and eventually died there in 1978.
