During the late 1940s several students saw a communist threat in the advent to government of a bunch of radical far-left politicians and decided to forestall the feared red invasion.

After a series of police raids netting several UCV "hotheads" and serious government warnings to the student’s parents, de Bellard Sr. decided to pack his son off to Colombia, to study at Bogotá University.

Seeing thousands of deaths, mass imprisonment and a resurfacing of the traditional Colombian animosity against Venezuelans, made Eugenio decide to return to Caracas and tell his father that he wanted to study law.

He directed and organized three successful explorations into the Amazon jungle, to places like the top of Tepuis with gigantic holes, to Tapirapeco, where they were the first non-Amazonian humans to be seen by several tribes in the border between Brazil and Venezuela.

In his own words: “During the serious international ordeal of October 1962, when the Kennedy/Kruschev crisis blew up due to Russian nuclear missiles shipped to Fidel Castro’s Cuba, he released important information to the Caracas American embassy on caves that had been visited in the country by the polish engineer that was accused in world press as one of the technicians that set up rockets with nuclear warheads in Cuban caves: Maciej Kuczynski” (Letter to the USA Embassy in Caracas Venezuela, August 5, 1995).
