Roberto Viaux

In August, 1973, Viaux was released and exiled to Paraguay. He was not involved in the successful Chilean coup of 1973, and was allowed to return to Chile only in 1990, by President Patricio Aylwin. Viaux lived quietly in retirement in Santiago, until his death on September 5, 2005.

On October 22, 1970, coup plotters loyal to Viaux attempted to kidnap constitutionalist Chilean Army Commander-in-chief General René Schneider, who was adamantly opposed to any prospect of a coup. General Schneider's official car was ambushed at a street intersection in the capital city of Santiago, Chile. When the general drew a gun to defend himself, he was shot point-blank several times. Though he was rushed to a military hospital, General Schneider's wounds proved fatal and he died three days later, on October 25. General Viaux was later convicted of involvement with the plot and imprisoned.

Prior to his involvement in the René Schneider case, Viaux was a very well respected and admired military leader. He became famous when he led a small military insurrection (the Tacnazo) on October 21, 1969. In the Tacnazo, Viaux shut himself up with the Tacna regiment inside its barracks and went on a strike. He demanded a pay-raise for the Army and the resignation of both the Defense Minister and the Army Commander-in-Chief. After tense negotiations with the government, he ended his strike when the Commander-in-Chief resigned and the government promised to study his salary demands.

Roberto Urbano Viaux Marambio (May 25, 1917 in Talca – September 5, 2005 in Santiago) was a Chilean Army General and the primary planner of two attempted coup d'états in Chile in 1969 and 1970. The first was against President Eduardo Frei Montalva, and the second sought to prevent Socialist Salvador Allende's election.
