The ERP-22 de Agosto was an Argentinian guerrilla splinter group of the Military Committee of the Federal District of the People's Revolutionary Army (ERP), established as a result of tactical divergences regarding the organization's position before the general elections of March 11, 1973.

ERP members who disagreed with this position were separated after the meeting of the Central Committee in December 1972 (the first in which Mario Santucho was present after returning from his exile in Cuba), in which they concluded that It was impossible to continue within the organization.

[3] The date of the name refers to the day of 1972 in which the first large-scale joint operation of the ERP, Montoneros and Peronist Armed Forces (FAP) guerrillas took place in order to free many of their main chiefs imprisoned in Rawson.

On November 11, 1973, the group also organized a tribute to the villero leader of the San Pablo neighborhood and militant Nemesio Aquino, a well-known local revolutionary and militant who the group describes as "the worker who knew how to embrace the ideas of revolutionary Marxism and build the organization political-military essential to galvanize the progress of the people in their struggle for power".

[6] Operation Poniatowski is planned for March 6, 1973, but due to problems in one of the cars, it is postponed to day 8, when it is actually executed, under the responsibility of Víctor José Fernández Palmeiro, known as "el Gallego".

The guerrillas reduced the staff and came to Garcia, who slept next to his partner, singer and actress Marina Dorel, and reassured him, while a female militant wore the uniform of one of the maids in case of the arrival of some unforeseen guest.

[6] At first it was believed that everything had been a maneuver to promote itself and although this theory was suggested, the editor knew that he had gone through a difficult experience and the ERP-August 22 had taken his first blow to affirm its independent existence.

A few days before the inauguration of elected president Héctor Cámpora, the ERP-22 decided to launch a new action: the "Operation Mercury", whose objective was to kill Counter-admiral Hermes Quijada.

The guerrillas proceeded to carry out several checks of the area, in order to study their safety and customs: they found as a problem the substantial custody at the nearby house of Minister Arturo Mor Roig, but they were able to determine that the officer usually left his house about the 8:30 and 9:30 in a white Dodge Polara driven by his chauffeur, and did not take a fixed route.

Again the responsibility of the operation fell to Víctor José Fernández Palmeiro aka “El Gallego”, who prepared a plan that consisted of following Quijada's car with a motorcycle (whose driver would receive a signal from a car parked on the direction taken by the Dodge Polara), the passenger would be the “Gallego”, who would jump from it and riddle Quijada with a Falcon submachine gun and then get on again and the driver swiftly take him out of the area .

What they did not say, is that as of April 30, Victor José Fernández Palmeiro (El Gallego), now next to the sixteen martyrs of Trelew, began to live in the heart of his town.
