Jefferson Cardim de Alencar Osorio

One of his worst persecutors, Ernesto Geisel, eventually became the fourth general dictator of the Brazilian military government from 1974 to 1979.

His plan was to visit several cities and military offices in the south of Brazil and inspire the population to revolt against the new government, overthrowing Castello Branco.

His first military action took place in the city of Três Passos in the northeast region of the Rio Grande do Sul state, together with 20 supporters he found along the way.

Cardim accepted the offer and left Montevideo by car, heading to Chile with his son, who was then 18 and an Uruguayan nephew aged 20.

The operation was monitored by the Brazilian military attaché in Buenos Aires, Colonel Nile Caneppa da Silva.

Two days later, the Uruguayan nephew was released, but Cardim and his son were returned to Brazil in an aircraft serving a Brazilian minister.
