Che Guevara in Cuba

“
Che convinced Castro with competence, diplomacy and patience. When grenades were needed, Che set up a factory to make them. When bread was wanted, Che set up ovens to bake it. When new recruits needed to learn tactics and discipline, Che taught them. When a school was needed to teach peasants to read and write, Che organized it.

Guevara arrived in Mexico City in early September 1954, and renewed his friendship with the other Cuban exiles whom he had known in Guatemala. In June 1955, López introduced him to Raúl Castro who later introduced him to his older brother, Fidel Castro, the revolutionary leader who had formed the 26th of July Movement and was now plotting to overthrow the dictatorship of Fulgencio Batista in what became the Cuban Revolution. Guevara recognized at once that Castro was the cause for which he had been searching.[26]
Although he planned to be the group's medic, Guevara participated in the military training with the members of the Movement, and, at the end of the course, was called "the best guerrilla of them all" by their instructor, Colonel Alberto Bayo.[27] The first step in Castro's revolutionary plan was an assault on Cuba from Mexico via the Granma, an old, leaky cabin cruiser. They set out for Cuba on November 25, 1956. Attacked by Batista's military soon after landing, many of the 82 men were either killed in the attack or executed upon capture; only 22 found each other afterwards.[28] Guevara wrote that it was during this bloody confrontation that he laid down his medical supplies and picked up a box of ammunition dropped by a fleeing comrade, finalizing his symbolic transition from physician to combatant.

Only a small band of revolutionaries survived to re-group as a bedraggled fighting force deep in the Sierra Maestra mountains, where they received support from the urban guerrilla network of Frank País, the 26th of July Movement, and local country folk. With the group withdrawn to the Sierra, the world wondered whether Castro was alive or dead until early 1957 when the interview by Herbert Matthews appeared in The New York Times. The article presented a lasting, almost mythical image for Castro and the guerrillas. Guevara was not present for the interview, but in the coming months he began to realize the importance of the media in their struggle. Meanwhile, as supplies and morale grew low, Guevara considered these "the most painful days of the war."[29]
At this point Castro promoted Guevara to comandante of a second army column. However, Guevara's first idea to hit an enemy garrison at Bueuycito did not go as planned. When his men were late to arrive, he began the attack without them. He told a sentry to halt, but when the sentry moved, Guevara decided to shoot. However, his gun jammed, as did the gun of the young rebel who was with him. Guevara fled under a hail of bullets, which in turn brought a hail of bullets from the rebels in the hills, and the barracks surrendered before Guevara repaired his tommy gun. As Guevara said, "My survival instincts took over.
As Guevara reconsidered his tactics, he imposed even harsher disciplinary treatment. Deserters were punished as traitors, and Guevara was known to send execution squads to hunt down those seeking to escape.[31] As a result, Guevara became feared for his brutality and ruthlessness.[32] During the guerrilla campaign, Guevara was also responsible for the execution of a number of men accused of being informers, deserters or spies.
Guevara was also instrumental in creating the clandestine radio station Radio Rebelde in February 1958, which broadcast news to the Cuban people and statements by the 26th of July movement, and provided radio telephone communication between the growing number of rebel columns across the island. Guevara had apparently been inspired to create the station by observing the effectiveness of CIA supplied radio in Guatemala in ousting the government of Jacobo Arbenz.

In late July of 1958 Guevara would play a critical role in the Battle of Las Mercedes by using his column to halt a force of 1,500 men called up by Batista's General Cantillo in a plan to encircle and destroy Castro's forces. Years later, USMC Major Larry Bockman, would analyze and describe Che's tactical appreciation of this battle as "brilliant".[35] As the war extended, Guevara led a new column of fighters dispatched westward for the final push towards Havana. In the closing days of December 1958, Guevara directed his "suicide squad" in the attack on Santa Clara, that became the final decisive military victory of the revolution.[36][37] Radio Rebelde broadcast the first reports that Guevara's column had taken Santa Clara on New Years Eve 1958. This contradicted reports by the heavily controlled national news media, which had at one stage reported Guevara's death during the fighting. Batista, upon learning that his generals were negotiating a separate peace with the rebel leader, fled to the Dominican Republic the next day on January 1, 1959.
