Establishment of the Political-Military Command of the Huallaga Front.
In November 1987, following the seizure of Juanjui by the MRTA, the government declared a state of emergency in San Martin and established the Huallaga Front Political-Military Command to combat the insurgency in the region.
After the MRTA raid on Juanjui on November 6, 1987, the department of San Martin was declared in a state of emergency. In November 1987, the Political-Military Command of the Huallaga Front was established as the Peruvian State's response to MRTA's armed actions in the region. This military command was created to coordinate counter-subversive operations in the department. The establishment of this command marked the beginning of an intense military campaign against MRTA that resulted in the dismantling of the Tupacamarista Army of the Northeastern Front between November and December 1987.
