At the end of 1989, the PCP-SL appeared in the Tamaya River and Imiria Lake. The Main Force of the Upper Huallaga made incursions into all the hamlets, imposing its organization and establishing Open Popular Committees and Organized Committees. The PCP-SL entered Puerto Alegre on November 4, 1989, one day after the incursion into Masisea. During the 1990 elections, Shining Path supporters stationed themselves on an esplanade near Puerto Alegre to prevent, under threat of death, the inhabitants of Tamaya and Imiria from going to Masisea to vote. The military response included helicopter bombings that attacked the subversives' main checkpoints.
