Large-scale army operations in the Upper Huallaga region
In 1989, following the Shining Path attack on Uchiza, the Peruvian army began large-scale operations in the Upper Huallaga, establishing multiple military bases and dismantling the urban structure of the PCP-SL. These operations marked the beginning of significant military setbacks for Shining Path in the region.
Beginning in 1989, the Peruvian army implemented large-scale operations in the Upper Huallaga that marked a turning point in the conflict with the PCP-SL. These operations began after the second attack on Uchiza on March 17, 1989, which resulted in a massacre of police and led to the re-declaration of the Alto Huallaga as an Emergency Zone, giving the army maximum authority over the region. Under the command of General Alberto Arciniegas Huby, the political-military headquarters were installed in Uchiza and military bases were established in Tulumayo, Nuevo Progreso, Pizana and Punta Arenas. These operations succeeded in dismantling the committees of parallel popular power (CPPP) of the PCP-SL, removing the Shining Path from the Marginal Highway and undermining their capacity to operate in urban centers.
