Army surprise in Agua Blanca
On December 23, 1987, the Peruvian Army surprised MRTA fighters in Agua Blanca, San Martin, after pursuing them after the capture of Juanjui. This attack was part of the counter-subversive campaign that caused a major setback to the Northeastern Front of MRTA.
After the seizure of Juanjui in November 1987, the MRTA returned to the same camp used before the attack. The Peruvian Army pursued them after a state of emergency was declared in the department of San Martin. Believing they had escaped the army, the MRTA fighters were surprised in Agua Blanca on December 23, 1987. This attack was part of the offensive of the Political-Military Command of the Huallaga Front established in November 1987. The confrontation resulted in a significant defeat for the Tupacamarista Army of the Northeastern Front.
