I: Patria o Muerte!
The attack on the Moncada Barracks turned out to be a strategical failure, but it would have a very big impact on the following years regardless of the outcome of the attack.
The rebels were caught and imprisoned, Fidel Castro was sentenced to fifteen years in prison and his brother Raúl got a sentence of thirteen years. Three other leaders got thirteen-year sentences while twenty other rebels received sentences of ten years and four got three years. The rest of the group got either under one year or couldn't be proven guilty.

The Batista regime believed that the major threats toward the brutal regime had been shot down, but after two years all political prisoners of Cuba had to be released due to external political pressure. The Castro brothers travelled to Mexico to live there in exile together with several other Cuban exiles. During this period Alberto Bayo, a leader of the Republican forces in the Spanish Civil War, decided to help them planning their revolution. It was also during this period that the Argentinian, Ernesto Che Guevara came in contact with the organization and decided to help them on their quest to start a fully fledged revolution towards the regime of Fulgencio Batista.

The threat towards the anti-Batista only grew bigger as time went on, and finally the "26th of July Movement" was born named in reference to the failed attack on the Moncada Barracks 26th of July 1953.
In November 1956 a yacht named Granma departed from Mexico towards the east of Cuba, the 60-foot yacht was loaded with 82 people and was overloaded with supplies and after two weeks of voyage the men disembarked two days later than planned due to having overloaded the yacht. They disembarked on the beach of Playa Las Coloradas in the south-western part of Cuba.
This is considered to be the attack that ultimately fired the Cuban Revolution. The Batista army encountered and severely wounded the group by killing two thirds of the men three days after the disembarking which resulted in a retreat into the Sierra Maestra mountains.
