Installation of military bases in Chongos Bajo, Huamancaca Chico, and Chupaca.
In 1991, under the Fujimori government, military bases were installed in Chongos Bajo, Huamancaca Chico and Chupaca as part of the counteroffensive against the PCP-SL in the Canipaco valley. These bases complemented those installed in 1990 in Chicche and San Juan de Jarpa, significantly reducing the Shining Path presence in the region.
In 1991, during Alberto Fujimori's administration, military bases were installed in the districts of Chongos Bajo, Huamancaca Chico and Chupaca, as part of the military counteroffensive in the Canipaco valley. These installations were added to the military bases previously established in 1990 in the districts of Chicche (Vista Alegre Annex) and San Juan de Jarpa. The installation of these military bases was part of a broader counterinsurgency strategy that included the forced formation of peasant patrols, also initiated in 1991. With the military presence, PCP-SL activity decreased significantly throughout the Canipaco valley.
