Incursions and operations on the left bank of the Huallaga river
For approximately four years (1990-1994), the population on the left bank of the Huallaga River suffered constant incursions and operations by both the Army and the PCP-SL, resulting in deaths of combatants and civilians, until the Army regained control of the area in 1993.
Between 1990 and the first months of 1994, the populations settled on the left bank of the Huallaga River suffered constant incursions and operations by the Army and the PCP-SL. Villagers hid in the bush during these confrontations, fearing both the Army and the Shining Path. The Army carried out operations with helicopter gunships that resulted in the deaths of both Shining Path members and civilians living in the area. In 1993, the Army regained control of Venenillo by establishing a military base at the entrance to Bolsón Cuchara and controlling the villages along the Marginal Highway on the right bank of the Huallaga River.
