PCP-SL incursion to Masisea
On November 3, 1989, the Main Force of the PCP-SL of Alto Huallaga raided Masisea, establishing popular committees in the area. This action was followed by the entry into Puerto Alegre the next day and later by the violent impediment of electoral participation in 1990.
On November 3, 1989, the Main Force (FP) of the PCP-SL from the Alto Huallaga raided Masisea. This incursion was part of a series of actions in which PCP-SL established Open Popular Committees and Organized Committees in the hamlets of the Tamaya River and Imiria Lake. One day later, on November 4, 1989, PCP-SL also entered Puerto Alegre. During the 1990 elections, the Shining Path members stationed themselves near Puerto Alegre to prevent, under threat of death, the inhabitants of Tamaya and Imiria from going to Masisea to vote. In response to these actions, a Self-Defense Committee (CAD) was formed in Masisea in 1991 with advice from the Navy.
