What was Che Guevara trying to accomplish in the Congo in 1965?

In 1965, Che Guevara traveled to the Democratic Republic of the Congo with a group of Cuban guerrilla fighters in an attempt to support the Patrice Lumumba Battalion, which was engaged in a civil war.1

This mission was part of Guevara's broader effort to foster revolution abroad after becoming increasingly disillusioned with the direction of the Cuban government and its reliance on the Soviet Union. Ultimately, his efforts in the Congo proved to be a failure, leading him to flee to Tanzania and later to a safe house near Prague.1
