 Upon Guevara 's return to Cuba in September 1959 , it was evident that Castro now had more political power . The government had begun land seizures included in the agrarian reform law , but was hedging on compensation offers to landowners , instead offering low interest " bonds " , a step which put the United States on alert . At this point the affected wealthy cattlemen of Camagüey mounted a campaign against the land redistributions , and enlisted the newly disaffected rebel leader Huber Matos , who along with the anti @-@ Communist wing of the 26th of July Movement , joined them in denouncing the " Communist encroachment " . During this time Dominican dictator Rafael Trujillo was offering assistance to the " Anti @-@ Communist Legion of the Caribbean " which was training in the Dominican Republic . This multi @-@ national force , composed mostly of Spaniards and Cubans , but also of Croatians , Germans , Greeks , and right @-@ wing mercenaries , was plotting to topple Castro 's new regime .
