Annihilation

The government orders the army to "annihilate the actions of subversion," first in Tucuman, then throughout the country. The first leader of the troops in Tucuman is General Adel Vilas, a disciple of the French, who defends torture as the weapon of choice in this type of battle and advocates the extension of the conflict to the universities. He is succeeded by General Domingo Bussi, who studied counterinsurgency in Vietnam. Swept out of Tucuman, the ERP attempts, in the final days of the year, a desperate attack on a Buenos Aires military installation. The attack's failure ultimately leads to the organization's demise. The Montoneros attack a military facility in the province of Formosa, something only the ERP had done until that point, and they are also repelled with heavy losses.
