After that war was lost, Bayo had a furniture factory in Mexico, and is said to have been an instructor at the Military Academy of Guadalajara. Bayo had contact in Mexico with prominent Latin American revolutionaries, and was associate/mentor of some, including Ernesto Che Guevara and Fidel Castro. While it is not known if he continued direct contact with Soviet Union agents such as "Comandante Carlos Contreras" Vittorio Vidali after the war was lost in Spain, both were present in Mexico for throughout the same period.
