Tania became one of Cuba’s most successful spies in Latin America, penetrating Bolivia’s highest political circles. When her cover was blown, she joined Che’s guerrilla group but was killed in an ambush in August 1967.

Ulises Estrada was the principal organizer of the Bolivia mission and trained Tania as the key undercover agent. Although “against the rules” in such espionage operations, they fell in love and intended to make a life together.
