The mission of the guerrillas of the IV Front consisted of operating on the Central Highway in the section between Holguín and Buenaventura with the objective of opening fire on military transports that were circulating, as well as intercepting civilian vehicles that were transporting agricultural products or provisions of all kinds. . Any army vehicle that tried to travel was shot at and that is why they began to pass in long convoys. By then the soldiers did not venture to travel at night.
